5/8-inch nuts, bolts, and washers to connect to the tower arm.

 Wood pole mounting only: one 1/4-inch diameter, 3 1/2-inch long lag bolt

Site Planning

To ensure safe and durable wiring, router installation must follow appropriate electrical and building codes. Follow all local codes and regulations. For example in the U.S., follow the National Electrical Code (NEC) requirements, unless local codes in your area take precedence over the NEC code.

Chapter 2 

The maximum length of Cat 5 cable for 10BaseT, 10/100BaseT , and 10/100/1000BaseT Ethernet connections is 300 feet (90 meters).

The Ethernet duplex and speed setting is configurable.

The U.S. 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.

Ethernet data cable installations having lengths greater th an 140 fee t in the outdo or environment mu st 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 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

Tropos routers are radio devices 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 possible sources of 2.4 GHz and 5 GHz interference, such as

cordless phones, wireless 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.

Site Surveys

Due to variations in component configuration, placement, and physical environment, each installation is unique. Before installing routers, 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.

 Antenna orientation—Proper antenna orientation 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. The Tropos 6410 and 6420 routers have integrated antennas; therefore, antenna location and orientation depend on the location of the unit.

 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. A void 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.

Safety

Installing the routers can pose a serious hazard. Be sure to take precautions to avoid the following:

 Exposure to high voltage lines during installation  Falls when working at heights or with ladders  Injuries from dropping tools and equipment  Contact with AC power wiring

Mounting Strategies

Note

When choosing mounting locations, consider the available mounting structures and antenna clearance. The 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 Router” on page 34 and

“Connecting Data and Power Cables” on page 29 to determine the best strategy for the selected

location.

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.

The mounting assembly contains two clamps to secure the router to the mounting structure.

Figure 3 illustrates the proper use of the clamps. The clamps must be routed through slots in the

pole bracket as shown in the figure, and then attached to the pole and tightened. The pole bracket should be leveled before it is secured to the pole.

Pole, Tower, and Streetlight Mounting Instructions

Note

This section explains how to mount the 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 24), and attempt to mount the router with maximum possible clearance around the antennas.

The router should always be mounted with the top of the router horizontal and level and with the antennas facing upward.

It is best to attach ground and data cables to the router before sliding the ro ut er in to the mo un tin g bracket, as explained in this section. Before mounting the router, review the wiring instructions in “Grounding the

Router” on page 34 and “Connecting Data and Power Cables” on page 29 to determine the best strategy

for the selected location.

Chapter 2 

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.
