MP-622 Installation Guide
About This Guide
This guide details how to install a Trapeze Networks™ Mobility Point™ (MP™) access point,
model MP-622, in a Trapeze Networks Mobility System™ wireless LAN (WLAN). The MP-622 is
suitable for installation outdoors.
This guide is intended for network administrators or others involved in installing MP access
points in a network
Trapeze Networks Mobility System
The Trapeze Networks Mobility System is an enterprise WLAN solution that seamlessly
integrates with an existing wired enterprise network. The Trapeze system provides secure
connectivity to both wireless and wired users in large environments such as office buildings,
hospitals, and university campuses.
The Trapeze Mobility System fulfills the three fundamental requirements of an enterprise
WLAN: it eliminates the distinction between wired and wireless networks, allows users to work
safely from anywhere (secure mobility), and provides a comprehensive suite of intuitive tools for
planning and managing the network before and after deployment, greatly easing the operational
burden on IT resources.
The Trapeze Networks Mobility System consists of the following components:
RingMaster tool suite—A full-featured graphical user interface (GUI) application used to
plan, configure, deploy, and manage a WLAN and its users
One or more Mobility Exchange™ (MX™) switches—Distributed, intelligent machines for
managing user connectivity, connecting and powering Mobility Point (MP) access points, and
connecting the WLAN to the wired network backbone
Multiple Mobility Point™ (MP™) access points—Wireless access points (APs) that
transmit and receive radio frequency (RF) signals to and from wireless users and connect them
to an MX switch
Mobility System Software™ (MSS™)—The operating system that runs all MX switches and
MP access points in a WLAN, and is accessible through a command-line interface (CLI), the
Web View interface, or the RingMaster GUI

MP-622 Installation Guide
1
MP-622 Overview
A 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.
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.
Hardware Overview
The 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 Characteristics
The 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.

External Antenna Options
The 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 num
This is a new command, and it is only supported in MSS 7.1 or higher.
Note:
The 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 Port
The 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.
1- 4
MP-622 Installation Guide
The 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.
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.
Power Injector Module
The 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
Ethernet Cabl e
Ground Wire
To MP-622
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.
The power injector module is designed for indoor or outdoor use.
Warning!
Grounding Point
In 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.

MP-622 Network Configurations
This chapter illustrates network configurations supported for the MP-622.
Infrastructure Configuration
In 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.

WLAN Mesh Configuration
WLAN 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
MX-216
Backbone
MX Switch
Mesh Portal AP
Mesh Link
Mesh AP
Client
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.

MP-622 Installation Guide
Wireless Bridge Configuration
You 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
MX-216
MX Switch
Building 1
Building 2
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
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.)
Installation Requirements and Recommendations
For best results, follow these requirements and recommendations before installing an MP-622.
RingMaster Network Plan and Work Orders
If 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 WLAN
MX Appliance Recommendation
Trapeze 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.
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.
Weather Conditions
When 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.
Installing and Connecting an MP-622
3–1
Installing and Connecting an MP-622
Installation Requirements and Recommendations
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 Cabling
When 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.
Note:
See the Outdoor Power Supply Installation Guide for details on installing the power
supply for the MP-622.
Grounding
It 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 Advisories
When 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 Exposure
Federal 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 Advisories
For additional radio safety warnings, the Regulatory Information document.

Installing an MP-622
Installing an MP-622
The 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 Unit
You can mount the MP-622 using either the pole-mounting bracket or the wall-mounting bracket.
Use one of the following procedures.
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.
Using the Pole-Mounting Bracket
Perform the following steps to mount the unit to a 1.5 to 2 inch diameter steel pole or tube using

4. Use the included nuts to tightly secure the MP-622 to the bracket.
Connecting External Antennas
For 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.

MP-622 Installation Guide
Installing and Connecting an MP-622
Installing an MP-622
1. Connect the Ethernet cable from the wireless bridge to the RJ-45 port labeled “Output” on the
power injector.
2. Connect a straight-through unshielded twisted-pair (UTP) cable from a local LAN switch to the
RJ-45 port labeled “Input” on the power injector. Use Category 5e or better UTP cable for 10/
100BASE-TX connections.
Warning!
You must align the UTP cable with the pins in the RJ-45 “Input” port. If you force the
cable into the port, you will damage the unit and can bend the power injector pins.
The picture below shows an example of a port with two bent bottom pins.
3. Insert the power cable plug directly into the standard AC receptacle on the power injector.
4. Plug the other end of the power cable into a grounded, 3-pin socket, AC power source.
Note:
For International use, you may need to change the AC line cord. You must use a line
cord set that has been approved for the receptacle type in your country.
Checking the LED Indicators
The 11a and 11b/g LEDs on the MP-622 operate in two display modes, which are configurable
through the software. The default AP mode indicates data traffic rates. The RSSI mode indicates
the received signal power and is used when aligning antennas in a bridge link.

Connecting an MP to an MX
Note:
For lightning protection at the power injector end of the cable, consider using a
lightning arrestor immediately before the cable enters the building.
You can connect an MP directly to an MX or indirectly to the MX through an intermediate Layer 2
or Layer 3 network. If you are connecting the MP directly to an MX, use the following procedure to
insert the cable into the MX and verify the link.
You can use the CLI or RingMaster to configure an MP connection. If you are installing the
MP-622 as a Mesh AP in a WLAN Mesh or wireless bridge configuration, you must configure the
MP connection before deploying the MP-622 in its final location. (See the Mobility System
Software Configuration Guide.)
Figure 3–7 shows how to insert a Cat 5 cable into 10/100 Ethernet port on an MX. Refer to this
figure as you perform the procedure.

Aligning Antennas for Bridge or Mesh Links
If 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.

MP-622 Installation Guide
Installing and Connecting an MP-622
Installing an MP-622
When 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.
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.
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.

Cables and Pinouts
This chapter describes the wiring and pin assignments for the cables and connectors that can be
used with the MP-622.
Twisted-Pair Cable Assignments
For 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.
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.
Warning!
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 Assignments
Use 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).
Cables and Pinouts
5–1
The 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 Wiring
Because 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.

Wireless Bridge Link Planning
The 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.
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.
Data Rates
Using 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.

Wireless Bridge Link Planning
6-1
Radio Path Planning
Although 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
Visual Line of Sight
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.
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.
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.

MP-622 Installation Guide
Antenna Height
A 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).

Total Link Distance
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.

Example
A 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
Wireless Bridge Link Planning
6-3
(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.
Never construct a radio mast, pole, or tower near overhead power lines.
Warning!
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.
Antenna Position and Orientation
Once 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 vertical
Antenna 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.

Radio Interference
The 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.
