25 Planning your WLAN Network The wireless network is much different with a wired network. The Installation of a wireless network requires some additional planning. This planning includes RF Link Engineering like RF Path planning, site selection, and back-bone network preparation. The radio links between all end sites are specified as three types of environmental connection listed as below: LOS(Line Of Sight) OLOS(Optical LOS) NLOS(Non LOS) Because High Frequency Radio travels in a straight forward line, a clear LOS(line-of-sight) between antennas is efficient and ideal. Frequently, locations of the desired links are fixed. When you cannot achieve a clear line-of-sight, you must plan according to a basic consideration: The Basic considerations for sites include: ▪ Installation Facility must be constructed (Electric Pole, Tower) ▪ Possibility of future obstructions - Trees that may obstruct the path - Buildings between the sites that may obstruct the path ▪ Lightening ▪ Distance between the sites and Network Structure. ▪ Strong RF interference
26 Site Survey & Planning Definition A site survey is a task-by-task process by which the surveyor discovers the RF behavior, coverage, interference, and determines proper hardware placement in a facility. The site survey’s primary objective is to ensure that mobile workers and the wireless LAN’s clients experience continuously strong RF signal as they move around the facility.

27 Wireless Network Planning Procedure 1 (Location) 1. Select and identify enough location candidates to determine freely as the install point regardless of some design change to some extent. 2. The most crucial parameter is the range at which APU and CSU or other Wi-Fi Client are required to operate. The range can be determined by a conventional formula which consider a various kinds of environmental and radio equipments. 3. Another consideration in installing APU and CSU is the network connection like a CATV Coaxial Cable and CAT5 Ethernet Cable. Even though some location is the best location in terms of RF performance, the actual installed location is restricted by a limitation of cable reach. Procedure 2 (Radio Link Path) 1. Choose the proper antenna type with a site survey result. 2. For best performance, mount the APU and CSU in a location where there is LOS(Line Of Sight) to each antenna. 3. Perform the field survey to summarize every obstacle like tree and earth bulge in consideration of OLOS(Optical LOS). 4. With the site survey result, adjust the tilt and angle of antenna so that there is maximum clearance within the FRESNEL ZONE of the direct path. Note: The best means of achieving FRESNEL ZONE clearance is to raise the height of APU or CSU mounting point as high as possible 5. In order to get the more exact information on RF radio link path, Calculate the Link Budget for Radio Link between APU and CSU which is referred in the end of this section. Note: The link budget is a rough calculation of all known elements of the link to determine whether the signal will have the proper strength to the other end of the link. Procedure 3 (RF Channel Selection) 1. Check all range of channels by RF measurement with Frequency Analyzer in order to see the interference effect with APU and CSU. Actually, RF interference is likely to arise from any other wireless system operating within the same frequency band as ISM/UNII Band Radio Products. Note: The final selection of operating channel should be done with the testing results of both APU and CSU. Procedure 4 (Radio Performance Tuning) Please refer to the Radio Link Test WLAN Cable Access Point 6220 NTPM99CA Rel 1.0 Issue 1 Aug 2004

48 Procedure 1-5 Checking CATV Signal and Power Level and Tuning Action Step Action 1. Connect an actual coaxial cable to the coaxial port on the APU. 2. Connect a measurement coaxial cable to the monitoring port on APU. 3. Measure the Signal Power level at monitoring port Note: In case of installation using a Trunk or Distribution Cable & Connector, it is crucially recommended to measure the RF Signal level directly at the termination of the coaxial cable from CATV AMP(TBA) or Splitter before connecting to APU in order to ensure a perfect operation of Cable Modem inside APU. If the measured Signal level is outside from the allowed range referred in DOCSIS, you should adjust the AMP Power level or perform another proper tuning method to meet the requirement of RF signal level. It is also recommended to measure AC voltage from CATV UPS Power Supply to ensure a perfect operation. Note: In case of installation using a Drop Cable, it is recommended to measure the AC voltage from Local CATV Power Supply to ensure a perfect operation. But if you can confirm that a power supply facility is compliant to the power requirement of APU, this step can be skipped 4. Check if the acquired power level converted by adding 20dBmV to monitored value satisfy the range (-15dBmV ~ +15dBmV) referred in DOCSIS standard. But, some level margin should be added to the measured power level by 1 ~ 3 dB. WLAN Cable Access Point 6220 NTPM99CA Rel 1.0 Issue 1 Oct. 2004

50 Procedure 1-6 Power ON and Visual Checking the LED Operation Action Step Action 1. Make sure that you know what each one of LED Lights means for the unit. Please refer to the LED indicators in Page 2. Turn ON the HFC Power Supply. 3. Check if the LED operation follows the pre-defined steps during and after booting. 4. Refer to the System Failure Analysis Procedure in the next page 5. Check if the LED 1(Power) is ON. Note: If there is no LED light, check if the power supply which provides the CATV (HFC) network with AC power (45 ~ 95VAC) signal is working properly and that the CATV power is detected at the end of the coaxial cable. (If any problem has been found in the power system, the unit has to be entered into a Repair Process) 6. Check if LED 2(CM Link) flashes for over 100 seconds from when power is first supplied. If the LED flashes for more than 100 seconds, check if the data signal level at the monitoring port on the APU meets the recommended range of the signal level.

52 CSU Installation & Configuration Mounting and Installation Concept Figure 3-25 CSU Installation Concept on User’s facility By default, CSU is pole mounted. Each unit is shipped with a pole mounting module. WLAN Cable Access Point 6220 NTPM99CA Rel 1.0 Issue 1 Oct. 2004
53 Procedure 2-1 Mounting the CSU on the Steel Wire Strand Action Step Action 1. Prior to an installation, check if the Pole has the strength and stability to sustain the weight of the CSU at a strong wind 2. Please find a mounting tool for installing CSU illustrated in Figure 3-26 3. Place the CSU face (RADOME side) down on a flat surface. 4. Using the mounting tool, attach the Mounting Tilt Brackets to the back of the CSU and insert the two stainless steel M6 hex head screws and M6 split lock washers into the hole. Figure 3-26 Assembling the mounting bracket on the CSU 5. Lift the CSU to the selected installation point on the pole and then attach the clamp to the original location while lashing the CSU to the pole or using a hoisting rope to keep the unit in place during mounting work. 6. Slide two mounting nuts through a washer to each bracket hole as illustrated in Figure 3-27 WLAN Cable Access Point 6220 NTPM99CA Rel 1.0 Issue 1 Aug 2004
54 7. Adjust the direction of CSU Antenna RADOME toward APU and fasten sufficiently to secure the CSU on the pole. Figure 3-27 Assembling the mounting bracket with a installation tool 8. Adjust the up/down tilt (- 50 º to 50 º) and move the top or bottom of the CSU until the unit is roughly positioned at the correct angle and height.

55 Procedure 2-2 Mounting the CSU on the Steel Wire Strand Action Step Action 1. Loosen the EMI cap and slide the CAT5 or 6 cable without RJ45 connector into the hole of the EMI cap shaped like hood. 2. Follow the conventional procedure of creating a CAT5 or 6 Ethernet cable Note: It is recommended to use a shielded cable like S-FTP(Foiled Twisted Pair) or STP (Shielded Twisted Pair) in which wire pairs are covered with overall shield material to prevent EMI effects to or from the near electronic devices or facilities. Note: The cable from CSU to POE Injector and from POE Injector to CPE (PC) should be a straight-through cable. 3. Connect a cable to the CSU’s POE port through the hole of EMI cap and tighten it firmly Figure 3-29 Connecting Ethernet Cable to CSU and Securing the Port Cap. WLAN Cable Access Point 6220 NTPM99CA Rel 1.0 Issue 1 Aug 2004
56 4. Secure the cable in the EMI cap by tightening it with a cable tie. Over-wrap the connectors with black self amalgamating tape or shrink the tubing with sliding over the cable to ensure a waterproof sealing. This is the most crucial step of the installation. If this procedure is not completed, a long-term and complex problems could occur. 5. Tighten the EMI cap securely with the special tool including the product package. WHEN INSTALLING THE UNIT, CHOOSE A LOCATION THAT PROVIDES A MINIMUM SEPARATION OF 20 cm FROM ALL PERSONS DURING NORMAL OPERATION.Figure 3-30 Over-wrapping the EMI Cap and Shielded Cable with a Tape or shrink tube 6. Connect the ground wire to the ground point at the lower right end of CSU back panel. Figure 3-31 Connecting the ground wire to the ground point 7. Connect the other end of the data cable to the POE Injector indoor. 8. Plug the power cord of the POE Injector into an electrical outlet WLAN Cable Access Point 6220 NTPM99CA Rel 1.0 Issue 1 Oct. 2004
57 Figure 3-32 Connecting CSU and User PC by an Ethernet Cable though POE Injector Mounting Tips • Verify the Line-of-Sight -- Before installing the CSU, make sure a clear line-of-sight exists. Line of sight (LOS) can be defined as each antenna clearly seeing the other antenna, and seeing the remote locations when viewing from the central base location. Be sure to look level with the center of origin of the transmission (i.e., the middle of the antenna). Repeat this procedure from the remote location. Any disruption of the signal path due to trees, buildings, or any other obstructions may cause the link to function incorrectly. If you see any obstructions between two antennas, move one or both antennas to another location. • Use mounting hardware provided to secure the unit to the pole. • Leave the unit mounting loose enough to allow for movement when performing the alignment/testing procedure. The unit should be tightened only after the alignment/testing procedure is completed. • Install the unit away from microwave ovens and 2.4 GHz cordless phones. Microwave ovens and some cordless phones operate on the same frequency as the unit and can cause signal interference. • Begin at the lowest point, so the tape overlaps from bottom to top creating a shingled effect. This creates an effective barrier against water runoff. Apply this "shingle effect" to each layer of the sealing process. Apply two layers of electrical tape to the connector, and leave approximately 3 inches of cable exposed on either side of the connector.
