design with good heat conduction. It is not waterproof and

therefore, should be installed at indoor locations only.

Figure 1: Indoor Coverage (Typical Application)

5.2. Typical In-Building Coverage

The R20 repeater is designed to provide optimal coverage over an area of

approximately 1,000 to 2000 sq. meters (10,000 to 20,000Sq ft.).

However, ultimate performance depends on the obstructions

blocking/absorbing of the RF signals in side the building and the available

forward signal level at the donor antenna. Typical coverage is usually

planned for relatively small areas such as large conference rooms or

several adjacent rooms in smaller office areas.

Coverage is primarily determined by the available forward signal level at

the outdoor antenna input, loss due to the RF cable length, type of RF

cable installed and achievable isolation for optimum R20 performance.

Indoor coverage varies greatly due to the nature of various building

construction techniques and materials. Approximations of signal

level/coverage can be determined with the following assumptions:

• 10-to12dBi-donor antenna. 7dBi indoor directional antenna.
