The  transceivers  are comprised of a Software Defined Indoor UnitTM (SDIDUTM) and outdoor unit (ODU). The SDIDUTM is a product and trademark of CarrierComm. This  manual  assumes  the  reader  has  a  basic  understanding  of  how  to  install  hardware,  use Windows  based  software,  and  operate  test  equipment.  For  the  purposes  of  this  manual,  the radios  are  referred  to  as  the  “Digital  Radio  Series”  except  where  it  is  necessary  to  make  a distinction between the models covered or their operating frequency ranges. 2.2  Introduction The  Microwave  Data  Systems  family  of  digital  radios  provides  high  capacity  transmission, flexibility,  features,  and  convenience  for  wireless  communications  networks.    These  radios represent  a  new  microwave  architecture  that  is  designed  to  address  universal  applications  for both  PDH  and  SDH  platforms.    This  advanced  technology  platform  provides  the  flexibility customers need for their current and future network requirements. The  radio  family  is  based  on  a  common  platform  used  to  support  a  wide  range  of  network interfaces and  configurations.  It supports links for 16 x E1/T1, 100BaseTX Ethernet, and  DS-3/E-3/STS-1 (optional, consult factory for availability).  The radio family is spectrum and data rate scalable,  enabling  service  providers  or  organizations  to  trade-off  system  gain  with  spectral efficiency  and  channel  availability  for  optimal  network  connectivity.    The  radio  family  enables network  operators  (mobile  and  private),  government  and  access  service  provides  to  offer  a portfolio of secure, scalable wireless applications for data, video, and Voice over IP (VoIP).  The MDS FOUR.9 Series digital radio family operates in the FCC Public Safety Band of 4.940 to 4.990 GHz, which is generically referred to as the “4.9 GHz band.”  It supports three types of user data payload connectivity as follows: •  100Base-TX  intelligent  bridging  between  two  locations  without  the  delay  and  expense  of installing cable or traditional microwave. •  Scalable Ethernet capability of 25 and 50 Mbps is included.  These scalable radios provide LAN  connectivity  and  offer  performance  trade-offs  between  operational  bandwidths,  data rates, and distance.
User Reference and Installation Guide    2-2 © 2006 Microwave Data Systems Inc.  All Rights Reserved.  MDS Digital Radio Series 05-4561A01, Rev. A  •  16E1 or T1 for cellular backhaul, enterprise voice applications and voice network redundancy The MDS SIX.4 Series digital radio family operates in the FCC Fixed Microwave Services band of 5.925 to 6.425 GHz, which is generically referred to as the “6.4 GHz band.”  It supports four types of user data payload connectivity as follows: •  Gigabit Ethernet intelligent bridging between two locations without the delay and expense of installing cable or traditional microwave. •  Scalable Ethernet capability of 16  to  131 Mbps is included.  These scalable radios provide LAN  connectivity  and  offer  performance  trade-offs  between  operational  bandwidths,  data rates, and distance.  •  32 T1 for cellular backhaul, enterprise voice applications and voice network redundancy with 85 Mbps of Ethernet •  SONET (Synchronous Optical Network) For customers such as cellular carriers requiring backhaul and backbone extension as well as service providers requiring network redundancy, new Points of Presence (POPs), and last mile access, the Digital Radio Series is a cost effective alternative to leased lines with carrier-class quality of performance.  The Digital Series radio is a cost effective solution to meet the growing demand for enterprise Local Area Network (LAN) connectivity between buildings and campuses as well as service providers requiring reliable products for infrastructure expansion, extending Metropolitan Area Network (MAN) fiber access, and network redundancy. The Digital Series includes integrated Network Management functionality and design features that enable simple commissioning in the field at the customer’s premises.  Furthermore, a highlight of MDS radio products is scalability and the capability to support a ring-type architecture.  This ring or consecutive point radio architecture is “self-healing” in the event of an outage in the link and automatically re-routes data traffic to ensure that service to the end user is not interrupted. The Digital Series radio system is composed of a Software Defined Indoor UnitTM (SDIDUTM) and Outdoor Unit (ODU).  It supports 1+0 and 1+1 protection and ring architectures in a single 1 Rack Unit (1RU) chassis.  The modem and power supply functions are supported using easily replaceable plug-in modules.  An additional feature of the SDIDUTM is provision for a second plug-in modem/IF module to provide repeater or east/west network configurations. The overall architecture consists of a single 1RU rack mount Software Defined Indoor Unit (SDIDUTM) with a cable connecting to an Outdoor Unit (ODU) with an external antenna.

A  Power Supply Input DC Input -48 VDC -48v (Isolated Input); 2-pin captive power connector. The unit requires an input of -48 volts dc ±10% at the front panel DC Input  connector.    The  total  required  power  is  dependent on the option cards and protection configuration (1+0, 1+1).  The SDIDUTM  front  panel  power  connector  pin  numbering  is  1 through 2, from left to right, when facing the unit front panel. Pin  1  is  the  power  supply  return  and  is  connected  to  unit chassis  ground  internally.    Pin  2  should  be  supplied  with  a nominal -48 V dc, with respect to  the  unit chassis (ground).  A  ground-isolated  supply  may  be  used,  provided  it  will tolerate grounding of its most positive output. The recommended power input is -44 to -52 V dc at 2 Amps minimum.  It is recommended that any power supply used be able to supply a minimum of 100 Watts to the SDIDUTM. A  mating  power  cable  connector  is  supplied  with  the SDIDUTM.    It  is  a  2-pin  plug,  5  mm  pitch,  manufactured  by Phoenix  Contact,  P/N  17  86  83  1  (connector  type  MSTB 2,5/2-STF).   This connector has screw clamp terminals that accommodate 24  AWG  to  12  AWG  wire.   The  power  cable wire  should  be  selected  to  provide  the  appropriate  current with  minimal  voltage  drop,  based  on  the  power  supply voltage  and  length  of  cable  required.    The  recommended wire size for power cables under 10 feet in length supplying -48 Vdc is 18 AWG. The  SDIDUTM  supplies  the  ODU  with  all  required power  via the  ODU/SDIDUTM  Interconnect  cable.    The  SDIDUTM  does not  have  a  power  on/off  switch.    When  DC  power  is connected to the SDIDUTM, the digital radio powers up and is operational.    There  can  be  up  to  204  mW  of  RF  power present at the antenna port (external antenna version).  The antenna should be directed safely when power is applied.

A  2.5  System Description The overall digital radio architecture consists of a single 1RU rack mount Software Defined Indoor UnitTM (SDIDUTM) with a cable connecting to an Outdoor Unit (ODU).  The ODU is designed for use  with  an  external  antenna  only.  This  SDIDUTM/ODU  architecture  is  advantageous  when compared to a single IDU with external mount antenna, since supporting a signal from the IDU rack to the antenna can result in significant signal losses, which would be difficult to avoid without the use of expensive coaxial cable or a waveguide. 163H160HFigure  2-4 shows the SDIDUTM  and  interfaces from a functional point of view.  The  functional partitions for  the  I/O,  Modem/IF,  and  power  supply  modules  are  shown.   The  SDIDUTM comes with  the  standard  I/O  capability  that  can  be  upgraded.    In  addition,  the  Modem/IF  function  is modular.  This allows the addition of a second Modem to support protection or ring architectures.  The power supply is similarly modular.

User Reference and Installation Guide    2-15 © 2006 Microwave Data Systems Inc.  All Rights Reserved.  MDS Digital Radio Series 05-4561A01, Rev. A  The  ODU  RF  Up/Down  Converter  card  provides  the  interface  to  the  antenna.    The  transmit section up-converts and amplifies  the modulated  Intermediate Frequency (IF) of 350  MHz from the  IF  Processor  and  provides  additional  filtering.    The  receive  section  down  converts  the received signal, provides additional filtering, and outputs an IF of 140 MHz to the IF Processor. The 64-QAM Modem performs the modulation and demodulation of the payload and forward error correction using advanced modulation and coding techniques.   Using  all-digital processing, the 64-QAM  Modem  uses  robust  modulation  and  forward  error  correction  coding  to  minimize  the number of bit errors and optimize the radio and network performance.  The 64-QAM Modem also scrambles,  descrambles  and  interleaves/de-interleaves  the  data  stream  in  accordance  with Intelsat standards to ensure modulation efficiency and resilience to sustained burst errors.  The modulation  will  vary  by  application,  data  rate,  and  frequency  spectrum.  The  highest  order modulation  mode  supported  is  64  Quadrature  Amplitude  Modulation  (QAM).  164H161HTable  2-5 summarizes the TCM/convolutional code rates for each modulation type supported by the MDS Digital Radio Series. Table 2-5.  MDS Digital Radio Series TCM/Convolutional Code Rates Modulation Type  Available Code Rates 16-QAM  3/4, 7/8, 11/12 32-QAM  4/5, 9/10 64-QAM  5/6, 11/12  The major functions of the SDIDUTM can be summarized as follows: •  I/O Processing – The SDIDUTM comes with a standard I/O capability that includes support for up to 16xT1/E1 and 2x100Base-TX  user payloads, 2x100Base-TX for SNMP, and  voice orderwire.   In addition,  option  cards  for  DS-3/E3/STS-1,  1-2  x  STM-1/OC-3,  and  4xDS-3/E3/STS-1  may  be added.  The SDIDUTM architecture is flexible and allows for the addition of other I/O types in the future. •  Switch/Framing  –  The  SDIDUTM  includes  an  Ethernet  Switch  and  a  proprietary  Framer  that  are designed to support 1+1 protection switching, ring architecture routing, and overall network control functions. •  Network  Processor  –  The  SDIDUTM  includes  a  Network  Processor  that  performs  SNMP  and Network Management functions. •  Modem/IF – The SDIDUTM Modem performs forward-error-correction (FEC) encoding, PSK/QAM modulation and demodulation, equalization, and FEC decoding functions.  The IF chain provides a 350  MHz  carrier,  receives  a  140  MHz  carrier,  processes  OOK  telemetry,  and  provides  –48V power.  Two modems can be used for 1+1 protection or ring architectures. •  Power Supply – The SDIDUTM power supply accepts -48 Vdc and supplies the SDIDUTM and ODU with power.  A second redundant power supply may be added as an optional module. The Modem Processor and its associated RAM, ROM, and peripherals control the digital and analog Modem  operation.  It  also  provides  configuration  and  control  for  both  the  IF  and  I/O  cards.  The
User Reference and Installation Guide    2-16 © 2006 Microwave Data Systems Inc.  All Rights Reserved.  MDS Digital Radio Series 05-4561A01, Rev. A  SDIDUTM  interfaces  with  the  ODU  to  receive  and  provide  modulated  transmit  and  receive waveforms.   The SDIDUTM also provides the physical interface for the user payload and network management.  In  transmit  mode,  the Framer  merges  user  payload  with  radio  overhead-encapsulated  network management data.  This combined data stream is transmitted without any loss of user bandwidth.  In the receive mode, the Framer separates the combined data stream received from the 64-QAM Modem.   The  SDIDUTM  supports  Scalable Ethernet  data  rates,  such as  25  or  50  Mbps  via the 100BaseT data interface port.   The  SDIDUTM  provides  network management  data  on  10  Mbps ports  accessible  via  the  10/100BaseTX  port.    The  Central  Processor  Unit  (CPU)  provides  the embedded control and network element functionality of the NMS.  The CPU also communicates with other functions within the SDIDUTM for configuration, control, and status monitoring. In Ethernet models, the payload of each user Ethernet data packet and all T1 can be encrypted using an AES encryption algorithm.  In addition, the encryption engine is re-seeded with a new, randomly generated key stream every 10 seconds, in order to provide enhanced security.   The initial key is based off of a pass phrase entered into each Digital Radio Series unit by the network administrator.  Consult factory for the availability of this encryption function. The power supply converts -48 Vdc to the DC voltage levels required by each component in the system. 2.6  Consecutive Point Architecture The consecutive point network architecture of the Digital Radio Series is based upon the proven SONET/SDH ring.  Telecommunications service providers traditionally use the SONET/SDH ring architecture to implement their access networks.  A typical SONET/SDH network consists of the service provider’s Point of Presence (POP) site and several customer sites with fiber optic cables connecting these sites in a ring configuration (see 165H162HFigure 2-5).  This architecture lets providers deliver high bandwidth with high availability to their customers.
User Reference and Installation Guide    2-17 © 2006 Microwave Data Systems Inc.  All Rights Reserved.  MDS Digital Radio Series 05-4561A01, Rev. A   Figure 2-5.  Ring Configuration. SONET/SDH rings are inherently self-healing.  Each ring has both an active path and a standby path. Network traffic normally uses the active path. Should one section of the ring fail, the network will switch to the standby path.   Switchover occurs in  seconds.  There may be a brief delay in service, but no loss of payload, thus maintaining high levels of network availability. The consecutive point architecture implemented in the Digital Radio family is based on a point-to-point-to-point topology that mimics fiber rings, with broadband wireless links replacing in-ground fiber cable.  A typical consecutive point network  consists of a POP and several customer sites connected  using  MDS  Digital  Radio  Series  units.    These  units  are  typically  in  a  building in  an east/west configuration.  Using east/west configurations, each unit installed at a customer site is logically connected to two other units via an over-the-air radio frequency (RF) link to a unit at an adjacent site. Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and in-building connections is repeated at each site until all buildings in the network are connected in a ring as shown in 166H163HFigure 2-6. .  For 2 x 1+0 and 2 x 1+1 nodes payload and NMS connections need to be jumpered between two SDIDUTMs.  For 1 x 2+0 nodes, there is no need for jumpers as there  is  a  single  SDIDUTM.    For  SDH  or  SONET  payloads,  the  configuration  is  similar  but  an external add/drop MUX and a second SDH/SONET interface card are required.

Consecutive Point Network 2.7  2 + 0 (East-West) Configuration  The  SDIDUTM  supports  an  east/west,  or  2+0,  configuration  that  allows  a  consecutive  point architecture to be achieved with only a single 1 RU chassis at each location.  In this configuration the SDIDUTM contains two modems supplies and may contain two power supplies.  One modem is referred to as the west modem and the other as the east modem.  The SDIDUTM is connected to two ODUs,  one broadcasting/receiving in one direction of the ring architecture and the other broadcasting/receiving in the other as shown in Figure 2-7.

In this configuration, protection is provided in a single 1 RU chassis.  The SDIDUTM contains two power supplies and two modems.  The power supply, ODU, IF/telemetry and modem are protected.  The digital framing and LIUs are not.  One modem is referred to as the west modem and the other as the east modem.    1+1 protection can be run in two modes called diversity and non-diversity.   In diversity mode, the link between each pair of modems is the same, as shown in 168H165HFigure 2-8, providing complete redundancy.  This arrangement requires bandwidth for both links and non-interference between the links, but it provides hitless receive and transmit switching.  The SDIDUTM supports both frequency and spatial diversity.  In frequency diversity, two frequencies are used.  In spatial diversity, two non-interfering paths are used.  In either case, the proprietary framer chooses the best, or error-free, data stream and forwards it to the Line Interface Units (Luis).

In this mode, one ODU at each location transmits to both two ODUs at the other location.  This mode does not require the extra bandwidth or interference protection of diversity mode.  It provides hitless receive switching and hot standby.  The SDIDUTM automatically switches transmit ODU upon appropriate ODU alarm or ODU interface error, minimizing transmit outage time.

This configuration provides individual 1 + 1 link protection as described in section 172H169H2.8, as well as the full-scale protection inherent in the consecutive point architecture as described in section 173H170H2.6.  At each location within the network, data may be dropped or inserted.  Front panel connections for drop/insert capability are shown in 174H171HFigure 2-11.  In this configuration each SDIDUTM contains two power supplies and two modems.

The Over-the-air channel has a data-bandwidth capacity that is set by the frequency-bandwidth, modulation, and coding.  The data-bandwidth may be allocated to various I/O card interfaces, including STM-1, 2 Mbps per E1, up to 50 Mbps Ethernet, and up to 1 Mbps NMS.  Only up to 100 Mbps of data-bandwidth may be allocated for Ethernet data, and the two I/O card 100BaseTX interfaces will share that 100 Mbps data-bandwidth. There is also an option mini-I/O card, which provides STM-1 Optical/OC-3 or STM-1 Electrical interfaces.  The optical interface is single mode at 1300 nm.  Consult factory for availability of Mini-IO STM-1/OC-3 Module. 2.11  Power Management RF power management is a radio design feature that controls the power level (typically expressed in dBm) of the RF signal received from a transmitter by a receiver.  The traditional goal of power management is to ensure that the RF signal at a receiver is strong enough to maintain the radio link under changing weather and link conditions. Traditional  power  management  techniques  such  as  Constant  Transmit  Power  Control  (CTPC) and Automatic Transmit Power Control (ATPC) transmit at  a  high power level  to  overcome the effects  of  fading and  interference.    However, these  techniques  continue  to  operate  at  a  higher
User Reference and Installation Guide    2-23 © 2006 Microwave Data Systems Inc.  All Rights Reserved.  MDS Digital Radio Series 05-4561A01, Rev. A  power level than needed to maintain the link in clear weather.  Because transmit power remains high when the weather clears, the level of system interference increases. Radios  operating  at  high  transmit  power  will  interfere  with  other  radios,  even  if  the  interfering source is miles away from the victim.  High interference levels can degrade signal quality to the point that wireless radio links become unreliable and network availability suffers.  The traditional solution to system interference is to increase the distance between radios. However, the resulting sparse deployment model is inappropriate for metropolitan areas. In response to the need for a high-density deployment model the MDS Digital Radio Series use a unique power control technique called AdTPC.  AdTPC enables MDS Digital Radio Series units to transmit  at  the  minimum  power  level  necessary  to  maintain  a  link  regardless  of  the  prevailing weather  and  interference  conditions.  The  MDS  Digital  Radio  Series  is  designed  and manufactured  to  not  exceed  the  +23  dBm  maximum  power  allowed.    The  purpose  of  power management is to minimize transmit power level when lower power levels are sufficient.  AdTPC also extends the concept of power management by controlling not only the power (dBm) of the RF signal, but its quality (signal-to-noise ratio) as well. In contrast to ATPC, the AdTPC technique dynamically adjusts the output power based on both the actual strength and quality of the signal.  Networked radios constantly monitor receive power and  maintain  10-12  BER  performance  under  varying  interference  and  climate  conditions.   Each radio detects when there is a degradation in the received signal level of quality and adjusts the transmit power level of the far-end unit to correct for it. AdTPC provides maximum power in periods of heavy interference and fading and minimum power when conditions are clear. Minimal transmit power reduces potential for co-channel and adjacent channel  interference  with  other  RF  devices  in  the  service  area,  thereby  ensuring  maximum frequency  re-use.  The  resulting  benefit  is  that  operators  are  able  to  deploy  more  radios  in  a smaller area. 2.12  MDS Digital Radio Series Software and Network Management All Digital Radio Series parameters are accessible in three ways: 1.  Using a standard web-browser via HTTP to access the built in webserver. 2.  Via SNMP using the fully featured MIB, allowing for automation of data collection and network management. 3.  Via a command line client accessible from a terminal client connected to the serial port, or telnet over the NMS Ethernet. The GUI, SNMP, and CLI control are discussed in the Digital Radio Series User Interface Manual.

This information is critical to the successful design and deployment of a network. Site  evaluations  are  required  to  confirm  whether  or  not  a  building  meets  network  design requirements.  The main objectives are as follows:

User Reference and Installation Guide    3-7 © 2006 Microwave Data Systems Inc.  All Rights Reserved.  MDS FOUR.9 Series 05-4561A01, Rev. A  3.6.2  Site Evaluation Process The following steps must be completed to perform a successful site evaluation.  Each step in the process is detailed in the following subparagraphs: •  Ensure RF Safety compliance: Ensure that appropriate warning signs are properly placed and posted at the equipment site or access entry.  For a complete list of warnings, refer the Safety Precautions listed at the beginning of this manual. •  Ensure  Compliance  with  Laws,  Regulations,  Codes,  and  Agreements:  Ensure  that  any installation performed as a result of the site evaluation is in full compliance with applicable federal and local laws, regulations, electrical codes, building codes, and fire codes. •  Establish Radio Line of Sight between radios: The most critical step in conducting a site evaluation is confirming a clear visual and radio Line of Sight (LOS) between a near radio and a far radio.  If LOS does not exist, another location must be used. Radios  used  in  a  link  must  have  a  clear  view  of  each  other,  or  visual  “line  of  sight”.  Binoculars may be used evaluate the path from the desired location of the near radio to the desired location of the far unit. To confirm Line of Sight: -  Ensure  that  no  obstructions  are  close  to  the  transmitting/receiving  path.    Take  into consideration trees, bridges, construction of new buildings, unexpected aerial traffic, window washing units, etc. -  Ensure  that  each  ODU  can  be mounted  in  the position  required  to  correctly  align it with its link partner. The radios must also have a clear radio line of sight. If a hard object, such as a mountain ridge or building, is too close to the signal path, it can damage the radio signal or reduce its strength. This happens even though the obstacle does not obscure the direct, visual line  of  sight.  The  Fresnel  zone  for  a  radio  beam  is  an  elliptical  area  immediately surrounding the visual path. It varies in thickness depending on the length of the signal path and the frequency of the signal. The necessary clearance for the Fresnel zone can be calculated, and it must be taken into account when designing a wireless links.   As shown in the picture above, when a hard object protrudes into the signal path within the Fresnel zone, knife-edge diffraction can deflect part of the signal and cause it to reach the  receiving  antenna slightly later  than  the  direct signal.  Since  these  deflected  signals are  out  of  phase  with  the  direct  signal,  they  can  reduce  its  power  or  cancel  it  out altogether.  If  trees  or  other  'soft'  objects  protrude  into  the  Fresnel  zone,  they  can attenuate (reduced the strength of) a passing signal. In short, the fact that you can see a

A  location  does  not  mean  that  you  can  establish  a  quality  radio  link  to  that  location. Microwave Data Systems provides a link planner spreadsheet that calculates the Fresnel ratio and helps  determine  link  feasibility.   Contact  your technical  support representative for a copy of the spreadsheet.   Determine  ODU  Mounting  Requirements:  ODUs  can  be  mounted  on  an  antenna  mast, brick, masonry or wall.  Refer to detailed installation sections. •  Determine SDIDUTM Installation Location: SDIDUsTM  can be installed tabletop or cabinet, wall mount, or rack mount.  The site must provide DC power or an optional AC/DC converter may be used.  Refer to detailed installation sections. •  Document Potential  Sources of  Co-location  Interference: When ODUs are located on  a roof  or  pole  with  other  transmitters  and  receivers,  an  interference  analysis  may  be required to determine and resolve potential interference issues.  The interference analysis needs  to  be  performed  by  an  RF  engineer.    The  specific  information  required  for  each transmitter and receiver includes the following: -  Transmitting and/or receiving frequency -  Type of antenna -  Distance from ODU (horizontal and vertical) -  Polarity (horizontal or vertical) -  Transmit power level -  Antenna direction •  Measure the Link Distance: The two ways to measure link distance are as follows: -  GPS: record the latitude and longitude for the near and far ODU sites and calculate the link distance.  Record the mapping datum used by the GPS unit and ensure the same mapping datum is used for all site evaluations in a given network. -  Range finder: measure the link distance (imperial or metric units may be used). Once  the  link  distance  has  been  measured,  verify  that  the  link  distance  meets  the availability requirements of the link.  Microwave Data Systems has created a spreadsheet tool that calculates the link availability based on the details of the link. The Microsoft Excel spreadsheet is available on Internet, at http://www.microwavedata.com/, and is shown on the following page. The following parameters should be entered (items in yellow): •  Operating Frequency: Enter 4900 •  Transmit Antenna Gain: Enter the gain of the external antenna. •  Transmit Output Power: Selectable between +5 to +23 dBm  in 1 dB steps. •  Receive Antenna Gain: Enter the gain of the external antenna if used.

A  Select the Grounding Location for both the ODU and SDIDUTM:  The units must be properly grounded in order to protect them and the structure they are installed on from lightning damage.  Final ODU/SDIDUTM installation requires: •  Grounding all ODUs as specified by supplier •  Grounding all SDIDUsTM to the rack •  Confirming the Presence of DC Power for the SDIDUsTM 3.6.3  Critical System Calculations 3.6.3.1  Received Signal Level (RSL) and Link Budget The received signal level (RSL) can be estimated using the following formula: RSL (dBm) = PTX + GTX ANT  – LPath + GRX ANT Where: PTX  is the transmitter output power (in dBm)             GTX ANT is the gain of the transmit antenna (in dB)             GRX ANT is the gain of the receive antenna (in dB) LPath    is the Path loss, defined by: LP    (dB) = 36.6 + 20log10(F*D) Where: F is the Frequency in MHz (4900 GHz), D is the Distance of path in miles This link budget is very important in determining any potential problems during installation.    The expected RSL and measured RSL should be close (+/- 5 to 10 dB) 3.6.3.2  Fade Margin Calculation The  fade  margin  is  the  difference  between  the  actual  received  signal  and  the  MDS  FOUR.9 Series  Radio’s  threshold  for  the  modulation  mode  selected.    The  fade  margin  can  be  used  to determine availability and should be at least 10 dB. 3.6.3.3  Availability Calculation Availability of the microwave path is a prediction of the percent of time that the link will operate without  producing  an  excessive  BER  due  to  multipath  fading.    Availability  is  affected  by  the following: •  Path length •  Fade margin
User Reference and Installation Guide    3-13 © 2006 Microwave Data Systems Inc.  All Rights Reserved.  MDS FOUR.9 Series 05-4561A01, Rev. A  •  Frequency •  Terrain (smooth, average, mountainous, valleys) •  Climate (dry, temperate, hot, humid) Depending on the type of traffic carried over the link and the overall network design redundancy, fade margin should  be included to support  the desired availability rate.  Critical data  and  voice may require a very high availability rate (99.999% or 4.9 minutes of predicted outage per year).  To  improve  availability,  the  fade  margin  can  be  increased  by  shortening  the  path  length, transmitting at a higher power level, or by using higher gain antennas. Availability can be computed using the following formula, which is known as the Vigants Barnett Method. Availability = 100 × (1 – P) P = 2.5 × 10-9 × C × F × D3× 10(-FM/10) Where F is the frequency in MHz (4900 MHz)            D is the distance in miles            FM is the fade margin in dB           C is the climate/terrain factor as defined below: Humid/Over Water: C = 4 (worst case channel) Average Conditions: C = 1 Dry/Mountains: C = 0.25 (best case channel)  Example: Assume 21 dB fade margin, over 5 miles with average climate/terrain, at 4.9 GHz.  The availability  comes  out  to  be  99.9986.    This  corresponds  to  the  link  being  unavailable  for  7.6 minutes per year. 3.6.4  Frequency Plan Determination When configuring Digital Radio Series units in a point-to-point or consecutive point configuration, careful engineering should be applied in order to minimize potential interference between nearby radios.    Nearby  radios  should  operate  on  different  frequencies,  transmitting  in  the  same  band (high  side  or  low  side).  When  designing  multi-radio  configurations,  antenna  size,  antenna polarization, and antenna location are critical.   The frequency plan must be selected based on desired data rate and expected link conditions.  In a  high  interference  environment  or  with  lower  gain  antennas,  higher  bandwidth,  more  robust modulation formats must be employed.  The available frequency plans are illustrated in Figure 3-3. The channel assignments  shown in the figures correspond to the channel numbers entered via the graphical user interface (GUI) or SNMP.

Frequency Plans for 4.9 GHZ and 6.4 GHz Band (Pubs Note: The lower chart needs to be revised for 6.4 GHz—Greg Mills?) 3.6.5  Antenna Planning The  ODU  must  be  used  with  an  external  antenna.    The  choice  of  antenna  should  provide adequate link performance for most applications. Larger antennas have the advantage of providing narrower beamwidths and high isotropic gain, which  yields  better  link  performance  (higher  fade  margin,  better  availability),  and  improves immunity to spatial interference (due to the smaller beamwidths).  However, larger antennas are more  costly  to  purchase  and  install  than  smaller  antennas  and  in  some  cases,  they  require special  equipment  for  installation  due  to  narrower  beamwidths.    They  are  also  more  easily affected by wind.

Consult factory for antenna manufacturer options. 1.  Select where the cable will enter the building from the outside. 2.  Determine the length of cable required.  Allow three extra feet on each end to allow for strain relief, as well as any bends and turns. 3.6.6  ODU Transmit Power Setup Setting the ODU transmit power is conditional on the band and application. The installer of this equipment is responsible for proper selection of allowable power settings. If there are any questions on power settings refer to your professional installer in order to maintain the FCC legal ERP limits. The SDIDUTM employs spectrally efficient shaped Quadrature Amplitude Modulation (QAM).  This waveform is not a constant envelope waveform.  Therefore, the average power and peak power are different.  The difference in peak and average power depends on the constellation type and shaping factor, where spectral efficiency such as more constellation points or lower shaping factor leading to peak powers higher than average powers.  The peak power is typically 5-7 dB greater than the average power in the SDIDUTM, and never exceeds 7 dB.  Regulatory requirements are usually based on peak EIRP which is based on peak power and antenna gain. 3.6.6.1  4.9 GHz Band In the 4.9 GHz Public Safety band the peak EIRP (Effective Isotropic Radiated Power) is limited to +57.8 dBm at the antenna for bandwidths up to 15 MHz and is reduced for narrower bandwidths in accordance with FCC Part 90.1215. The ODU must therefore be adjusted so that the station does not exceed the allowable limit. The installer is responsible during set up of transmit power to not exceed FCC limits on transmission power. These maximum power levels are provided in Table 3-2 for various antenna configurations, along with the operational bandwidths.  Note that though regulatory limits are stated in terms of peak power, the system transmit power levels are calibrated as averaged power readings. Average power is used for link calculations. Therefore the levels provided in table 3-2 are average power levels that have been certified to correspond with the maximum peak EIRP allowed. EIRP is calculated for link budget with external antennas as,  EIRP(avg) dBm = External Antenna Gain (dBi) + 23 dBm 3.6.6.1.1  ODU with External Antenna  When using external antennas with gains greater than 23 dBi, the transmit power must be reduced in dB from that given in Table 3-1 by the antenna gain difference above 23 dBi for the mode that is being used. For example, using a 6-foot dish antenna with 37 dBi gain, the output power would be dropped by

A    Antenna Gain (External) – 23 dBi = Antenna Gain Difference 37.6 dBi – 23 dBi = 14.6 dB For mode 100FE1 (single channel configuration with 30MHz emission bandwidth) the power would be lowered from    Tx Power – Antenna Gain Difference = Tx Power (External Ant) +5 dBm – 14.6 dB =  -9.6 dBm (-10 dBm).  Table 3-1 also presents transmit power settings for various antenna dish sizes. For link budget, EIRP (Avg) dBm = 37 dBi + Tx Power Setting (dBm). Table 3-2.  Maximum Power Settings for 4.9GHz Public Safety Band Operation (US). Antenna Diameter Antenna Gain, dBi* (example) Maximum Tx Power Setting, dBm EIRP 8 foot dish  39.5  17  56.5 6 foot dish  36.1  21  57.1 4 foot dish  33.1  23  56.1 3 foot dish  30.5  23  53.5 2 foot dish  27.1  23  50.1 * Note: Many antenna manufacturers rate antenna gain in dBd (dB referred to a dipole antenna) in their literature. To convert to dBi, add 2.15 dB. Power settings for other modes of operation can be easily extrapolated from Table 3-2. For link budget calculations,  EIRP (Avg) dBm= Antenna Gain (dBi) + Tx Power Setting (dBm).  Though transmitter radiated power is limited in the 4.9 GHz band regardless of antenna size, the receiver benefits from gain of larger antennas.  3.6.6.2  6.4 GHz Band In the 6.4 GHz Fixed Microwave Services band the peak EIRP (Effective Isotropic Radiated Power) is limited to +55 dBw at the antenna for any bandwidths. The ODU must therefore be adjusted so that the station does not exceed the allowable limit. The installer is responsible during set up of transmit power to not exceed FCC limits on transmission power.  EIRP is calculated for link budget with external antennas as,

A  3.7  Installation of the Digital Radio Series The following sections provide installation guides for: •  SDIDUTM Installation •  ODU Installation 3.7.1  Installing the Software Defined IDUTM The SDIDUTM can be installed in the following three options: 1.  Table top or cabinet 2.  Wall mount 3.  Rack mount The SDIDUTM should be: •  Located where you can easily connect to a power supply and any other equipment used in your network, such as a router or PC. •  In a relatively clean, dust-free environment that allows easy access to the rear grounding post as well as the front panel controls and indicators.  Air must  be able to pass freely over the chassis. •  Accessible for service and troubleshooting. •  Protected from rain and extremes of temperature (it is designed for indoor use). 3.7.1.1  Installing on a Table Top or Cabinet The SDIDUTM can be placed on a tabletop or cabinet shelf.  In order to prevent possible disruption, it is recommended to use a strap to secure the SDIDUTM. 3.7.1.2  Installing on a Wall An installation option for the SDIDUTM is mounting the unit to a wall.  If the wall mount option is being considered, plan to position the SDIDUTM at a height that allows LEDs, the connectors on the front panel, and the rear grounding post to be visible at all times and easily accessible.  Also, including plastic  clamps  to  support and  arrange  the  ODU/ SDIDUTM  Interconnect Cable should also be considered.

SDIDUTM Dimensions 3.7.2  Installing the ODU The ODU is intended for mounting on either a pole or antenna mast.  Each site must be  assessed for  the mounting method, location, and height.   After defining the mounting location and height for the ODU, re-confirm the line of sight. When operating a  1+1 configured  SDIDU™, i.e. an SDIDU™ with two  power supplies and two modem modules installed, in 1+0 mode, the ODU must be connected to the modem in the bottom slot.  If the ODU is connected to the modem in the top slot, the SDIDU™ will not communicate with the ODU, and a link cannot be established. 3.7.2.1  Installing the Mounting Poles First  install  the  mounting  poles,  on  which  you  will  mount  the  ODU.  It  is  important  to  note  the direction in which the ODU will point when installing the mounting pole. The  mounting  pole  must  be  mounted  in  a  vertical  position.    Failure  to  do  so  may  result  in improper alignment of the ODU.  Vertical tilt of the ODU is accomplished from the tilt-mounting bracket. The mounting pole must be grounded.  Now that you have installed the mounting pole, you are ready to install the ODU onto the mounting poles.  Refer to80H177HFigure 3-6 through 181H178HFigure 3-9.

Allow three extra feet on each end to allow for strain relief, as well as any bends and turns.
User Reference and Installation Guide    3-24 © 2006 Microwave Data Systems Inc.  All Rights Reserved.  MDS FOUR.9 Series 05-4561A01, Rev. A  3.  Route the cable. The SDIDUTM is equipped with TNC female connector on the front of the chassis.  Depending on the  ODU  type,  it  will  be  equipped  with  either  a  N-type  or  TNC  female  connector  at  its interconnecting  port.    A  length  of  coaxial  cable  (such  as  Times  Microwave  Systems  LMR-400, LMR-300 or LMR-200) fitted with the appropriate N-type or TNC male connectors is required to connect the ODU to the SDIDUTM.  This cable assembly may be supplied in fixed lengths with the digital  radio.    Bulk  coaxial  cable  of  equivalent  specification may  also be  used,  with  terminating connectors applied during cable installation. Based on an evaluation of the cable routing path, pull the ODU/SDIDUTM Interconnect cable from one unit to the other, utilizing cable trays, ducts, or conduit as required.  Take care that the ODU/ SDIDUTM Interconnect cable is not kinked or damaged in any way during installation.  Be sure to protect  the  TNC  connectors  from  stress,  damage and  contamination  during  installation  (do  not pull  the  cable  by  the  connectors).    If  multiple  ODU/  SDIDUTM  Interconnect  cables  are  to  be installed along the same route, the cables should all be pulled at one time.  Be sure the installed cable does not have any bends that exceed the specified cable bend radius.  The ODU/ SDIDUTM Interconnect cable should be adequately supported on horizontal runs and should be restrained by hangers or ties on vertical runs to reduce stress on the cable.  Outside the building, support and restrain the cable as required by routing and environmental conditions (wind, ice). The ODU/SDIDUTM and interconnection must be properly grounded in order to protect it and the structure it is installed on from lightning damage.  This requires that the ODU, any mounting pole or mast and any exposed interconnect cable be grounded on the outside of the structure.  The SDIDUTM  must  be  grounded  to  a  rack  or  structure  ground  that  also  has  direct  path  to  earth ground. The  ODU  must  be  directly  connected  to  a  ground  rod  or  equivalent  earth  ground.    The  ODU/ SDIDUTM interconnect cable  should  also  be  grounded  at  the  ODU, where  the  cable enters  the structure and at intermediate points if the exposed cable run is long (typically at intervals of 100 ft),  with  the  cable  manufacturer’s  grounding  kits.    Lightning  protection  devices  used  with  the interconnect  cable  must  be  appropriate  for  the  transmission of  the  interconnect  signals  (DC  to 350 MHz).   Provide a sufficient but not excessive length of cable at each end to allow easy connection to the ODU  and  SDIDUTM without  stress  or  tension  on  the  cable.    Excessive  cable  length,  especially outdoors,  should  be  avoided  to  minimize  signal  attenuation  and  provide  a  more  robust  and reliable  installation.    If  installing  using  bulk  coaxial  cable,  terminate  the  ODU/  SDIDUTM Interconnect cable at each end with a TNC male connector on the SDIDUTM side and either a N-type  or  TNC  male  connector  on  the  ODU  side  that  is  appropriate  for  the  cable  type.    Use  of connectors,  tools  and  termination  procedures  specified  by  the  cable  manufacturer  is recommended.  Once the cable has been installed but before connection has been made to either unit, a simple DC continuity test should be made to verify the integrity of the installed cable.  A DC continuity tester or digital multimeter may be used to verify a lack of DC continuity between the cable center conductor  and  outer  conductor,  with  the  opposite  end  of  the  cable  unconnected.    With  a temporary test lead or shorting adapter connected to one end of the cable, DC continuity should be verified between the center and outer conductors at the opposite end.

The following information will assist you in the event that servicing becomes necessary. TECHNICAL ASSISTANCE Technical assistance for MDS products is available from our Technical Support Department during business hours (8:00 A.M.–5:30 P.M. Eastern Time). When calling, please give the complete model number of the radio, along with a description of the trouble/symptom(s) that you are experiencing. In many cases, problems can be resolved over the telephone, without the need for returning the unit to the factory. Please use one of the following means for product assistance: Phone: 585 241-5510   E-Mail: mailto:TechSupport@microwavedata.com FAX: 585 242-8369  Web: http://www.microwavedata.com/ FACTORY SERVICE Component level repair of radio equipment is not recommended in the field. Many components are installed using surface mount technology, which requires specialized training and equipment for proper servicing. For this reason, the equipment should be returned to the factory for any PC board repairs. The factory is best equipped to diagnose, repair and align your radio to its proper operating specifications. If return of the equipment is necessary, you will be issued a Service Request Order (SRO) number and return shipping address. The SRO number will help expedite the repair so that the equipment can be repaired and returned to you as quickly as possible. Please be sure to include the SRO number on the outside of the shipping box, and on any correspondence relating to the repair. No equipment will be accepted for repair without an SRO number. A statement should accompany the radio describing, in detail, the trouble symptom(s), and a description of any associated equipment normally connected to the radio. It is also important to include the name and telephone number of a person in your organization who can be contacted if additional information is required. The radio must be properly packed for return to the factory. The original shipping container and packaging materials should be used whenever possible.
