5/8-inch nuts, bolts, and washers to connect to the tower arm.
Wood pole mounting only: two 5/8-inch diameter, 3-inch long lag bolts
Preparing for Installation
Site Planning
To ensure safe and durable wiring, installation of the Tropos 5320 MetroMesh router must
follow appropriate electrical and building codes. Follow the National Electrical Code (NEC)
requirements, unless local codes in your area take precedence over the NEC code.
The following distance limits apply to installations that have 10/100 Base-T Category 5 network
cables attached to the Tropos 5320 MetroMesh router:
300 feet maximum between devices for 100BaseT operation
600 feet maximum for 10BaseT operation.
The Ethernet duplex and speed setting is configurable.
Note
National Electrical Codes (NEC) Article 800 requires the use of Agency Listed (UL/CSA/TUV) Building
Entrance Protector for all power and data communications cables entering a building. The NEC
intends by Article 800 to protect the building and occupants from fires caused by transient voltage and
current surges.
Note
Ethernet data cable installations having lengths greater than 140 feet in the outdoor environment must
use a UL497 approved (UL/CSA/TUV Listed) primary protection device at the building entrance.
Ethernet data cable installations having lengths less than 140 feet in the outdoor environment may use
Tropos 5320 MetroMesh Router Installation Guide 4
a UL497A (UL/CSA/TUV Listed) secondary protection device at the building entrance. Tropos Data
Protection Device and Network Protection Units are UL497A secondary protection devices.
Location Guidelines
The Tropos 5320 MetroMesh router is a radio device and therefore susceptible to interference
that can reduce throughput and range. Follow these guidelines to ensure the best performance:
Install the unit in an area where trees, buildings, and large steel structures do not obstruct
radio signals to and from the antenna. Direct line-of-sight operation is best.
Install the unit away from microwave ovens or other devices operating in the 2.4 GHz or 5
GHz frequency range.
Install the unit away from other possible sources of 802.11a or 802.11b/g interference, such
as cordless phones, home spy cameras, frequency hopping (FHSS) and DSSS LAN
transceivers (non-802.11), electronic news gathering video links, radars, amateur radios,
land mobile radio services, local government sites (such as law enforcement), fixed
microwave services, local TV transmission and private fixed point transmitters.
Preparing for Installation
Antenna Options
You can purchase the Tropos 5320 MetroMesh router with an integrated omni-directional
antenna, or use an approved external antenna. Omni-directional antennas are best for systems
requiring a signal distribution in more than one direction. To comply with regulatory RF
exposure limits, locate antennas a minimum distance of 7.9 inches (20cm) from people. For
antenna model numbers, refer to “Approved Antenna Configurations and Attenuation Settings”
on page 48.
Note
Antenna(s) must be installed by a trained professional. Operating the unit with non-qualified antennas
is a violation of U.S. FCC Rules Part 15.203(c), Code of Federal Regulations, Title 47. See “Approved
Antenna Configurations and Attenuation Settings” on page 48 for a listing of antenna options.
Site Surveys
Due to variations in component configuration, placement, and physical environment, each
installation is unique. Before installing the Tropos 5320 MetroMesh router, perform a site
survey to determine the optimum placement of units for maximum range, coverage, and network
performance. Consider the following factors when performing a site survey:
Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum
radio range is achieved at the lowest workable data rate. A decrease in receiver threshold
sensitivity occurs as radio data rate increases.
Tropos 5320 MetroMesh Router Installation Guide 5
Antenna type and placement—Proper antenna configuration is a critical factor in
maximizing radio range. As a general rule, range increases in proportion to gain and antenna
height measured from the ground.
Physical environment—Clear or open areas provide better radio range than closed or filled
areas. The less cluttered the operating environment, the greater the range.
Obstructions—A physical obstruction, such as a building or tree, can block or hinder
communication. Avoid locating antennas in a location where there is an obstruction between
sending and receiving devices.
Building materials—Radio penetration is influenced by the building material used in
construction. For example, drywall construction permits greater range than concrete blocks.
Diversity—The Tropos 5320 MetroMesh router supports transmit and receive diversity for
802.11b/g. Diversity requires two antennas.
Power Source

Mounting Strategies
When choosing mounting locations, consider the available mounting structures and antenna
clearance. The Tropos 5320 MetroMesh router should always be mounted with the top of the
unit horizontal and level and with the antennas facing upward.
It is usually best to attach ground and data cables to the router prior to mounting. Before
mounting the router, review the wiring instructions in “Grounding the Tropos 5320 Router” on
page 21 and “Connecting a Data Port” on page 29 to determine the best strategy for the selected
location.
Note
To eliminate potential interference from the mounting structure, the router should be
mounted with at least 4 feet of clearance around the antennas.
Acceptable options for mounting on a streetlight are shown in Figure 2. In each case the router is
mounted to assure clearance for the antennas above the height of the streetlight.

Pole, Tower, and Streetlight Mounting Instructions
Pole, Tower, and Streetlight Mounting Instructions
This section explains how to mount the Tropos 5320 MetroMesh router on a pole, tower, or
streetlight. It is best to mount the router to aluminum or galvanized steel structures. The
mounting brackets are designed to pierce any oxidation layers that are on the outside of the pole,
thereby assuring good quality connection to the grounded structure.
Due to potential antenna obstruction issues, the router is not designed to be directly mounted on
a building wall. If it is necessary to mount the router on a wall, follow the instructions for
mounting on a wooden pole (“Wood Pole Mounting” on page 13), and attempt to mount the
router with maximum possible clearance around the antennas.
Note
The Tropos 5320 MetroMesh router should always be mounted with the top of the router horizontal
and level and with the antennas facing upward.
Note
It is best to attach ground and data cables to the router before sliding the router into the mounted sun
shield, as explained in this section. Before mounting the router, review the wiring instructions in
“Grounding the Tropos 5320 Router” on page 21 and “Connecting a Data Port” on page 29 to
determine the best strategy for the selected location.
Note
Mounting to wood, concrete, or painted poles may require primary grounding for the unit. Check the
national electrical codes in your area for specific rules.
