MP-622 Overview 1 - 111MP-622 OverviewA Trapeze Networks Mobility Point (MP) model MP-622 provides IEEE 802.11 wireless access to the network. MP access points are designed for use with a Trapeze Networks Mobility Exchange (MX). MPs require hardware installation only. All configuration for an MP is performed on the MX. Hardware OverviewThe MP-622 provides only external antenna options and is designed to operate as the “root bridge” in point-to-multipoint configurations, supporting wireless bridge connections to as many as six units. The MP is housed in a weatherproof enclosure for mounting outdoors and includes brackets for attaching to a wall, pole, radio mast, or tower structure. The unit is powered through an Ethernet cable connection from a power injector module installed indoors.A wireless bridge system offers a solution for connectivity between remote Ethernet wired LANs, or to provide Internet access to an isolated site where a wired link may be difficult or expensive to deploy. The wireless bridge connection provides data rates of up to 54 Mbps.Radio CharacteristicsThe IEEE 802.11a and 802.11g standards use a radio modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/CA). The 802.11a standard operates in the 5 GHz Unlicensed National Information Infrastructure (UNII) band, and the 802.11g standard in the 2.4 GHz band. IEEE 802.11g includes backward compatibility with the IEEE 802.11b standard. IEEE 802.11b also operates at 2.4 GHz, but uses Direct Sequence Spread Spectrum (DSSS) and Complementary Code Keying (CCK) modulation technology to achieve a communication rate of up to 11 Mbps.The MP-622 provides a 54 Mbps half-duplex connection for each active channel.Warning!Installation must be performed by qualified service personnel only. Read and follow all warning notices and instructions marked on the product or included in the documentation. Before installing the product, read the Regulatory Information document. The Trapeze Regulatory Information document is located at: http://www.trapezenetworks.com/support/contact_support/ and can be downloaded in PDF format.Note:The MP radios are disabled by default and can be enabled only by a system administrator using the MX.

MP-622 Installation Guide1 - 4The table below describes the wireless status LEDs in RSSI mode.External Antenna OptionsThe AP bridge provides various external antenna options for both 5 GHz and 2.4 GHz operation. In a point-to-multipoint configuration, an external high-gain omnidirectional, sector, or high-gain panel antenna can be attached to communicate with bridges spread over a wide area. The MP-622 unit requires an omnidirectional or sector external antenna for 2.4 GHz operation. The MP-622 supports one or two antennas per radio. If there are two antennas connected to the radio then antenna diversity is used to send all traffic types. If there is one antenna then proper operations of antenna diversity may be affected. By default there is one external antenna so there will be no use of antenna diversity for MPs with external antennas defined.set ap num radio num external-antennas numThe MP-622 supports one or two antennas per radio. If there are two antennas they must be the same antenna model. A single antenna will always be connected to the connector 1 for 2.4 GHz and connector 3 for 5Ghz.The MP-622 supports four antenna ports, two for the 11a radio and two for the 11bg radio. The supported antennas models are: 802.11bg Radio ANT-1120-OUT ANT-1360-OUT 802.11a Radio ANT-5120-OUT ANT-5360-OUT ANT-5PNL-OUT (for single antenna only for use on port 3)External antennas connect to the N-type RF connectors on the wireless bridge either directly or using coaxial cables.Ethernet PortThe wireless bridge has one 10BASE-T/100BASE-TX 8-pin DIN port that connects to the power injector module using the included Ethernet cable. The Ethernet port connection provides power to the wireless bridge as well as a data link to the local network.LED Status Description11a(three LEDs)Off No signal detected or the 802.11a radio is disabled.Slow Flashing Green The 802.11a radio is enabled with a low level signal.Fast Flashing Green Indicates a medium level signal.On Green Indicates a high level signal.11b/g(three LEDs)Off No signal detected or the 802.11b/g radio is disabled.Slow Flashing Green The 802.11b/g radio is enabled with a low level signal.Fast Flashing Green Indicates a medium level signal.Note:This is a new command, and it is only supported in MSS 7.1 or higher.

MP-622 Overview 1 - 5The wireless bridge appears as an Ethernet node and performs a bridging function by moving packets from the wired LAN to the remote end of the wireless bridge link.Power Injector ModuleThe MP-622 receives power through the network cable connection using Power-over-Ethernet (PoE) technology. An outdoor power injector module is available seperately and provides two RJ-45 Ethernet ports, one for connecting to the MP-622 (PoE Output), and the other for connecting to an MX or a local LAN switch Data (Input).The Input port uses an MDI (i.e., internal straight-through) pin configuration. You can therefore use straight-through twisted-pair cable to connect this port to most network interconnection devices such as a switch or router that provide MDI-X ports. However, when connecting the access point to a workstation or other device without MDI-X ports, you must use crossover twisted-pair cable.Figure 1–3. Power Injector Module The MP-622 does not have a power switch. It is powered on when the Ethernet port is connected to the power injector module, and the power injector module is connected to an AC power source.The power injector module automatically adjusts to any AC voltage between 100-240 volts at 50 or 60 Hz. No voltage range settings are required.Grounding PointIn order for the MP-622 includes a built-in lightning protector to work properly, the unit must be properly connected to ground. A grounding screw is provided for attaching a ground wire to the unit.Note:The power injector module does not support Power over Ethernet (PoE) based on the IEEE 802.3af standard. The wireless bridge unit must always be powered on by being connected to the power injector module.Warning!The power injector module is designed for indoor or outdoor use.Ground WireEthernet Cabl eTo MP-622

MP-622 Network Configurations 2 - 122MP-622 Network ConfigurationsThis chapter illustrates network configurations supported for the MP-622.Infrastructure ConfigurationIn an infrastructure topology, the MP-622 provides access to a wired LAN for 802.11a/b/g wireless workstations. Since the MP-622 has a weatherproof casing, it can be installed outdoors (for example, on a pole) to provide network access to clients located outside.Figure 2–1. Infrastructure Topology with Outdoor AP The MP-622 can be connected directly to an MX or indirectly over the network.ClientBackboneMX-216MX SwitchCampus Building

MP-622 Installation Guide2 - 2WLAN Mesh ConfigurationWLAN mesh services allow an MP to provide wireless services to clients without a wired interface for the MP. Instead of a wired interface, the MP has a radio link to another MP with a wired interface.WLAN mesh services can be used at sites where running Ethernet cable to a location is inconvenient, expensive or impossible. Note that power must be available at the location where the Mesh AP is installed.The following illustration shows how a client can connect to a network using WLAN mesh services.Figure 2–2. WLAN Mesh Topology In the illustration, a client is associated with a Mesh AP, which is an MP without a wired interface to the network. The Mesh AP is configured to communicate with a Mesh Portal AP, an MP with wired connectivity to an MX. Communication between the Mesh AP and the Mesh Portal AP takes place over a secure radio link (a Mesh Link). When associated with the Mesh AP, the client has the same connectivity to the network as if the Mesh AP is using a wired link.The Mesh AP and Mesh Portal AP make use of both radios. One radio (for example, the 802.11a radio) can be used for Mesh Link communications, using an SSID reserved for this purpose, while the Mesh AP can use its other radio for client associations in the same way a non-Mesh AP can.ClientMesh APMesh Portal APMesh LinkBackboneMX-216MX Switch

MP-622 Network Configurations 2 - 3Wireless Bridge ConfigurationYou can use WLAN mesh services in a wireless bridge configuration, with MP-622 units serving as bridge endpoints in a transparent Layer 2 bridge. A typical application of wireless bridging is to provide network connectivity between two buildings using a wireless link, as shown in the following illustration.Figure 2–3. Point-to-Point Wireless Bridge Topology The wireless bridge is established between a Mesh Portal AP and a Mesh AP to which it is associated. The bridged data packets are those present on the Ethernet interfaces of the two MPs. A Mesh AP serving as a bridge endpoint picks up packets from a wired port and transfers them to the other bridge endpoint. A simple source/destination learning mechanism is used to avoid forwarding packets across the bridge unnecessarily.A Mesh Portal AP serving as a bridge endpoint can support up to five Mesh APs serving as bridge endpoints in a point-to-multipoint configuration.

Installing and Connecting an MP-622 3 – 133Installing and Connecting an MP-622Installation Requirements and RecommendationsFor best results, follow these requirements and recommendations before installing an MP-622.RingMaster Network Plan and Work OrdersIf you are using RingMaster to plan your Trapeze Networks Mobility System installation, you might want to create and verify a network plan for the entire Trapeze network installation and generate an MP work order, before installing MP access points. A network plan and the MP work orders generated from it provide the following information about MP access point installation and configuration: Number of MP access points required for adequate WLAN capacity in each coverage area Detailed installation location for each MP access point Settings for all MP access points in the WLANMX Appliance RecommendationTrapeze Networks recommends that you install and configure the MX before installing an MP. If the MX is already installed and configured for the MPs, you can immediately verify the cable connection(s) when you plug the cable(s) into the MP.Weather ConditionsWhen planning an MP-622 installation, you must take into account any extreme weather conditions that are known to affect your location. Consider these factors: Temperature — The MP-622 is tested for normal operation in temperatures from -30 to 55 °C (-22 to 131 °F). Operating in temperatures outside of this range may cause the unit to fail. Wind Velocity — The MP-622 can operate in winds up to 90 MPH and survive higher wind speeds up to 125 MPH. You must consider the known maximum wind velocity and direction at the site and be sure that any supporting structure, such as a pole, mast, or tower, is built to withstand this force. Lightning — The MP-622 includes built-in lightning protection, except anntenna ports. However, you should make sure that the unit, any supporting structure, and cables are all properly grounded. Additional protection using lightning rods, lightning arrestors, or surge suppressors may also be employed. Note:Before installing an MP, you might need to generate a network plan and an MP work order with RingMaster. (See RingMaster Network Plan and Work Orders below.)Warning!MP model MP-622 is designed to receive power only from a Trapeze-approved power injector. Connecting an MP access point to a Power over Ethernet (PoE) device that is not approved by Trapeze Networks can damage the equipment.

Installing and Connecting an MP-622Installation Requirements and RecommendationsMP-622 Installation Guide3 – 2 Rain — The MP-622 is weatherproofed against rain. Also, prolonged heavy rain has no significant effect on the radio signal. However, it is recommended to apply weatherproof sealing tape around the Ethernet port and antenna connectors for extra protection. If moisture enters a connector, it may cause a degradation in performance. Snow and Ice — Falling snow, like rain, has no significant effect on the radio signal. However, a build up of snow or ice on antennas may cause a degradation in performance. In this case, the snow or ice has to be cleared from the antennas to restore proper operation of the unit.Ethernet CablingWhen you have determined a suitable location for the MP-622, you must plan a cable route from the MP-622 outdoors to the power injector module indoors. Consider these points: The Ethernet cable length should never be longer than 328 ft (100 m). Determine a building entry point for the cable. Determine if conduits, bracing, or other structures are required for safety or protection of the cable. For lightning protection at the power injector end of the cable, consider using a lightning arrestor immediately before the cable enters the building.GroundingIt is important that the MP-622 unit, cables, lightning arrestors, and any supporting structures are properly grounded. The MP-622 unit includes a grounding screw for attaching a ground wire. Be sure that grounding is available and that it meets local and national electrical codes.MP Radio Safety AdvisoriesWhen you enable the MP radio(s) as part of MX configuration, the radios are able to receive and transmit radio frequency energy as soon as you connect the MP to the MX, either directly or through the network. Radio Frequency ExposureFederal Communications Commission (FCC) Docket 96-8 for Spread Spectrum Transmitters specifies a safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC-certified equipment. When used with the proper antennas (shipped in the product), Trapeze Networks MP access point products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1-1991. Proper installation of the MP access point according to the instructions in this manual will result in user exposure that is below the FCC recommended limits.Additional Radio Safety AdvisoriesFor additional radio safety warnings, the Regulatory Information document.Note:See the Outdoor Power Supply Installation Guide for details on installing the power supply for the MP-622.

Installing and Connecting an MP-622Installing an MP-622Installing and Connecting an MP-622 3 – 3Installing an MP-622The MP-622 includes a bracket kit for mounting the unit to a 1.5 to 2 inch diameter steel pole or tube. The pole-mounting bracket allows the unit to be mounted to part of a radio mast or tower structure. The unit also has a wall-mounting bracket kit that enables it to be installed on a building wall or roof when using external antennas.Hardware installation of the MP-622 involves these steps:1. Mount the unit on a wall, pole, mast, or tower using the mounting bracket.2. Mount external antennas on the same supporting structure as the MP-622 and connect them to the unit.3. Connect the Ethernet cable and a grounding wire to the unit.4. Connect the power injector to the Ethernet cable, a local LAN switch, and an AC power source.5. For wireless bridge or Mesh Services installations, align antennas at the bridge or mesh link endpoints.Mounting the UnitYou can mount the MP-622 using either the pole-mounting bracket or the wall-mounting bracket. Use one of the following procedures.Using the Pole-Mounting BracketPerform the following steps to mount the unit to a 1.5 to 2 inch diameter steel pole or tube using the mounting bracket:Note:If you are installing the MP-622 as a Mesh AP in a WLAN Mesh or wireless bridge configuration, the MP does not have a wired link to an MX. You must configure the MP connection using a wired link to an MX before deploying the MP-622 in a final location. See the Mobility System Software Configuration Guide for information about configuring WLAN Mesh Services and wireless bridging.Note:Always attach the bracket to a pole with the open end of the mounting grooves facing up.

Drill four holes in the wall that match the screws and wall plugs included in the bracket kit, then secure the bracket to the wall.4. Use the included nuts to tightly secure the MP-622 to the bracket. Connecting External AntennasFor some applications, when deploying an MP-622, you must mount external antennas and connect them to the unit. Typically, access point operation requires a 2.4 GHz antenna, and bridge link operation requires a 5.0 GHz antenna.The primary port for 802.11bg (2.4Ghz) is port 1 and the primary port for 802.11a is Port 3. The MP-622 supports one or two antennas connected to each band. If you install one antenna it must be installed in the primary port. If you install two antennas they must be the same antenna model. There are no additional configuration requirements for adding the second antenna. If antenna diversity between the two antennas is a desired option it must be configured.The default for the 802.11bg radio is ANT-1360-OUT. set ap apnum radio num antennatype {ANT-1120-OUT | ANT-1360-OUT | ANT-5360-OUT | ANT-5120-OUT | ANT-5PNL-OUT}The antenna-location must be either indoors or outdoors.

Installing and Connecting an MP-622Installing an MP-622MP-622 Installation Guide3 – 14Aligning Antennas for Bridge or Mesh LinksIf you are installing MP-622 units for wireless bridge or Mesh Services operation, after the units have been mounted, connected, and the radios are operating, the antennas must be accurately aligned to ensure optimum performance on the bridge or mesh links. This alignment process is particularly important for long-range point-to-point links. In a point-to-multipoint configuration, the Mesh Portal AP uses an omnidirectional or sector antenna, which does not require alignment, but Mesh APs still need to be correctly aligned with the Mesh Portal antenna. Point-to-Point Configurations – In a point-to-point configuration, the alignment process requires two people at each end of the link. The use of cell phones or two-way radio communication may help with coordination. To start, you can just point the antennas at each other, using binoculars or a compass to set the general direction. For accurate alignment, monitor the RSSI’s LED indicator as you move the antenna horizontally and vertically. Point-to-Multipoint Configurations – In a point-to-multipoint configuration all Mesh APs must be aligned with the Mesh Portal antenna. The alignment process is the same as for point-to-point links, but only the Mesh AP end of the link requires the alignment.The LEDs are viewed right to left as you look at the back of the MP. The range from 1 to 12 will cover the signal range to accurately align the antenna. The signal strength LEDs indicate the received radio signal strength for a particular bridge link. The more LEDs that turn on, the stronger the signal. (RSSI level 1 should equate to the lowest useful signal). Alternatively, you can monitor the Receive Signal Strength Indicator (RSSI) value directly from the management interface. The higher the RSSI value, the stronger the signal.When you move the antenna during alignment, the radio signal from the remote antenna can be seen to have a strong central main lobe and smaller side lobes. The object of the alignment process is to set the antenna so that it is receiving the strongest signal from the central main lobe.Figure 3–8.

Installing and Connecting an MP-622Installing an MP-622Installing and Connecting an MP-622 3 – 15When aligning the antennas the MP with the antenna that is being aligned to must be set to send link-calibration packets. Use the following command to setup the MP that the MP-622 is being aligned with.set ap num radio num link-calibration mode {enable | disable}Link-calibration should be disabled under normal operation of the MP.If the MP-622 is installed with two directional antennas, connect the first antenna to the primary antenna port with antenna diversity off and align it. Then disconnect the first antenna and connect the second antenna to the primary antenna port. If the second antenna is being aligned with a different MP, disable link-calibration on the original MP and enable it on the new MP. Once both antennas are properly aligned, connect them to their desired ports.To align the antennas in the link using the output LEDs, start with one antenna fixed and then perform the following procedure to align the other antenna:1. Pan the antenna horizontally back and forth while checking the RSSI LEDs. If using the pole-mounting bracket with the MP-622, you must rotate the mounting bracket around the pole. Other external antenna brackets may require a different horizontal adjustment.2. Find the point where the signal is strongest (all LEDs on) and secure the horizontal adjustment in that position.3. Loosen the vertical adjustment on the mounting bracket and tilt the antenna slowly up and down while checking the LEDs.4. Find the point where the signal is strongest and secure the vertical adjustment in that position.Note:Sometimes there may not be a central lobe peak in the RSSI LED indicators because vertical alignment is too far off and only two similar peaks for the side lobes are detected. In this case, fix the antenna so that it is halfway between the two peaks.

Cables and Pinouts 5 – 155Cables and PinoutsThis chapter describes the wiring and pin assignments for the cables and connectors that can be used with the MP-622.Twisted-Pair Cable AssignmentsFor 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. The following figure illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.Figure 5–1. Pin Numbering on RJ-45 Connector 10/100BASE-TX Pin AssignmentsUse unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).Warning!Each wire pair must be attached to the RJ-45 connectors in a specific orientation.Warning!Never plug a phone jack connector into a power injector RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.1881

MP-622 Installation Guide5 – 2The RJ-45 Input port on the power injector is wired with MDI pinouts. This means that you must use crossover cables for connections to PCs or servers, and straight-through cable for connections to switches or hubs. However, when connecting to devices that support automatic MDI/MDI-X pinout configuration, you can use either straight-through or crossover cable.Straight-Through WiringBecause the 10/100 Mbps Input port on the power injector uses an MDI pin configuration, you must use “straight-through” cable for network connections to hubs or switches that only have MDI-X ports. However, if the device to which you are connecting supports automatic MDI/MDI-X operation, you can use either “straight-through” or “crossover” cable.Figure 5–2. Straight-Through Cable Wiring Crossover WiringBecause the 10/100 Mbps port on the power injector uses an MDI pin configuration, you must use “crossover” cable for network connections to PCs, servers or other end nodes that only have MDI ports. However, if the device to which you are connecting supports automatic MDI/MDI-X operation, you can use either “straight-through” or “crossover” cable.Figure 5–3.

Wireless Bridge Link Planning 6 - 166Wireless Bridge Link PlanningThe MP-622 supports fixed point-to-point or point-to-multipoint wireless links. A single link between two points can be used to connect a remote site to a larger core network. Multiple bridge links can provide a way to connect widespread Ethernet LANs.For each link in a wireless bridge network to be reliable and provide optimum performance, some careful site planning is required. This chapter provides guidance and information for planning your wireless bridge links.Data RatesUsing a 5 GHz integrated antenna, the MP-622 can operate over a range of up to 9.6 miles (15.4 km) or provide a high-speed connection of 54 Mbps. However, the maximum data rate for a link decreases as the operating range increases. A 9.6 mile link can only operate up to 6 Mbps, whereas a 54 Mbps connection is limited to a range of 0.81 mile (1.3 km).When you are planning each wireless bridge link, take into account the maximum distance and data rates for the various antenna options. A summary for 5 GHz (802.11a) antennas is provided in the following table. For full specifications for each antenna, see Antenna Specifications. Note:The planning and installation of a wireless bridge link requires professional personnel that are trained in the installation of radio transmitting equipment. The user is responsible for compliance with local regulations concerning items such as antenna power, use of lightning arrestors, grounding, and radio mast or tower construction. Therefore, it is recommended to consult a professional contractor knowledgeable in local radio regulations prior to equipment installation.Table 6– 1.

MP-622 Installation Guide6 - 2Radio Path PlanningAlthough the MP-622 uses IEEE 802.11a radio technology, which is capable of reducing the effect of multipath signals due to obstructions, the wireless bridge link requires a “radio line-of-sight” between the two antennas for optimum performance. The concept of radio line-of-sight involves the area along a radio link path through which the bulk of the radio signal power travels. This area is known as the first Fresnel Zone of the radio link. For a radio link not to be affected by obstacles along its path, no object, including the ground, must intrude within 60% of the first Fresnel Zone. The following figure illustrates the concept of a good radio line-of-sight.Figure 6–1. Radio Line-of-Sight If there are obstacles in the radio path, there may still be a radio link but the quality and strength of the signal will be affected. Calculating the maximum clearance from objects on a path is important as it directly affects the decision on antenna placement and height. It is especially critical for long-distance links, where the radio signal could easily be lost.When planning the radio path for a wireless bridge link, consider these factors: Avoid any partial line-of-sight between the antennas. Be cautious of trees or other foliage that may be near the path, or may grow and obstruct the path. Be sure there is enough clearance from buildings and that no building construction may eventually block the path. Check the topology of the land between the antennas using topographical maps, aerial photos, or even satellite image data (software packages are available that may include this information for your area) Avoid a path that may incur temporary blockage due to the movement of cars, trains, or aircraft.Note:For wireless links less than 500 m, the IEEE 802.11a radio signal will tolerate some obstacles in the path and may not even require a visual line of sight between the antennas.Visual Line of Sight Radio Line of Sight

Wireless Bridge Link Planning 6 - 3Antenna HeightA reliable wireless link is usually best achieved by mounting the antennas at each end high enough for a clear radio line of sight between them. The minimum height required depends on the distance of the link, obstacles that may be in the path, topology of the terrain, and the curvature of the earth (for links over 3 miles).For long-distance links, a mast or pole may need to be constructed to attain the minimum required height. Use the following table to estimate the required minimum clearance above the ground or path obstruction (for 5 GHz bridge links).To avoid any obstruction along the path, the height of the object must be added to the minimum clearance required for a clear radio line-of-sight. Consider the following simple example, illustrated in the figure below.Figure 6–2. Establishing a Clear Line-of-Sight ExampleA wireless bridge link is deployed to connect building A to a building B, which is located three miles (4.8 km) away. Midway between the two buildings is a small tree-covered hill. From the above table it can be seen that for a three-mile link, the object clearance required at the mid-point is 5.3 m (17.4 ft). The treetops on the hill are at an elevation of 17 m (56 ft), so the antennas at each end of the link need to be at least 22.3 m (73 ft) high. Building A is six stories high, or 20 m Table 6– 2.

MP-622 Installation Guide6 - 4(66 ft), so a 2.3 m (7.5 ft) mast or pole must be constructed on its roof to achieve the required antenna height. Building B is only three stories high, or 9 m (30 ft), but is located at an elevation that is 12 m (39 ft) higher than building A. To mount an antenna at the required height on building B, a mast or pole of only 1.3 m (4.3 ft) is needed. Antenna Position and OrientationOnce the required antenna height has been determined, other factors affecting the precise position of the MP-622 must be considered: Be sure there are no other radio antennas within 2 m (6 ft) of the MP-622 Place the MP-622 away from power and telephone lines Avoid placing the MP-622 too close to any metallic reflective surfaces, such as roof-installed air-conditioning equipment, tinted windows, wire fences, or water pipes The MP-622 antennas at both ends of the link must be positioned with the same polarization direction, either horizontal or verticalAntenna Polarization — The MP-622’s integrated antenna sends a radio signal that is polarized in a particular direction. The antenna’s receive sensitivity is also higher for radio signals that have the same polarization. To maximize the performance of the wireless link, both antennas must be set to the same polarization direction. Ideally the antennas should be pointing upwards mounted on the top part of a pole.Figure 6–3. Antenna Polarization Markings on the MP-622 Warning!Never construct a radio mast, pole, or tower near overhead power lines.Note:Local regulations may limit or prevent construction of a high radio mast or tower. If your wireless bridge link requires a high radio mast or tower, consult a professional contractor for advice.

Wireless Bridge Link Planning 6 - 5Radio InterferenceThe avoidance of radio interference is an important part of wireless link planning. Interference is caused by other radio transmissions using the same or an adjacent channel frequency. You should first scan your proposed site using a spectrum analyzer to determine if there are any strong radio signals using the 802.11a channel frequencies. Always use a channel frequency that is furthest away from another signal.If radio interference is still a problem with your wireless bridge link, changing the antenna polarization direction may improve the situation.
