Chapter 1. Site Planning
The installation of a wireless network requires much the same basic planning as any wired network. The
main difference is that the wireless signal requires some additional planning. This planning includes RF
path planning, site preparation, and installation of outdoor components, such as outdoor units, antennas,
lightning protection devices, and cabling suitable for outdoor conditions.
Although the technology implemented in this broadband fixed wireless system can make use of multi-
path signals to reduce the effect of obstructions in the path, the characteristics of the path must be
carefully examined. With this knowledge, components and network requirements can be correctly
planned for your specific application.
This section provides insight into the planning necessary to prepare your site for your broadband fixed
wireless system.
General Considerations
A basic consideration is the physical location of the sites at each end of the link. Because microwave
signals travel in a straight line, a clear line-of-sight between antennas is ideal. Frequently, however, the
locations of the desired links are fixed. When you cannot achieve a clear line-of-sight, you must plan
accordingly.
Other general site considerations include:
▪ Whether a tower must be constructed (and whether permits are required)
▪ Possibility of future obstructions
º Will trees grow high enough to interfere with the signal? Are there plans to erect buildings
between the sites that may obstruct the path?
▪ Availability of grounding
º Good grounding is important. Also, in areas prone to lightning, a lightning arrestor is strongly
recommended.
▪ Distance between the indoor portion of the system and the user’s network.
▪ Whether the SU may potentially be served by different BSUs. Prior to installation, try to determine
the best BSU access and available sighting location.
▪ Whether strong RF interference exists in the neighborhood, within or adjacent to the operating
frequency.
The following sections are provided to help you determine which information is critical to your site, and to
aid in the decision-making process.

Specific Considerations
Weather
You should research any unusual weather conditions common to the site location. These conditions can
include excessive amounts of rain, wind velocity, or extreme temperature ranges. If extreme conditions
exist that may affect the integrity of the radio link, take these conditions into consideration early in the
planning process.
Rain
Except in extreme conditions, attenuation (weakening of the signal) due to rain does not require serious
consideration for frequencies up to the range of 6 GHz. When microwave frequencies are at the 10-12
GHz range or higher, attenuation due to rain becomes much more of a concern, especially in areas where
rainfall is of high density and long duration. The systems discussed in this manual operate at frequencies
below 6 GHz, so rain is not a concern.
Temperature
Temperature can adversely affect the radio link when phenomena such as temperature inversion or very
still air accompanied by stratification occur. Temperature inversion can negate clearances; still air, along
with stratification, can cause severe refractive or reflective conditions, with unpredictable results.
Temperature inversions and stratification can also cause ducting, which may increase the potential for
interference between systems that do not normally interfere with each other. Where these conditions
exist, you should use shorter paths and adequate clearance.
Wind
Any system components mounted outdoors are subject to the effect of wind. You should know the
direction and velocity of the wind common to the site. Antennas and their supporting structures must be
able to prevent these forces from affecting the antenna or causing damage to the building or tower on
which the components are mounted. Antenna designs react differently to wind forces. This is known as
wind loading.
BSU and SU Wind Loading
Maximum operational wind speed during operation of BSUs and SUs is 50 m/s (112mph).
Survivable wind speed (tested to equivalent speed) is 90m/s (200mph).
The wind loading effect of the BSU and SU on their respective mounting masts is provided in Figure 1
(BSU) and Figure 2 (SU). The units of force in pounds can be converted to metric units by multiplying by
