ARNING
In order to satisfy the FCC RF exposure requirements, you must ensure that the
installation complies with the following:
One antenna is connected via cable that has typical 1~10 dB attenuation (depends
on the length of the cable) to the BDA base port. This antenna is installed outdoor
and has very sharp beam (Yagi type or similar) pointed to the donor (BTS). This
type of antenna has about 10dBi gain. Typical specifications: gain: 8 dBd (=10.1
dBi), VSWR: better than 1.5:1, Impedance: 50 ohm. The outdoor antenna must be
installed to provide a minimum separation distance of 1 m (100 cm) from persons
within the area.
The second antenna is connected to the BDA MOBILE port. There are two
applications: Outdoor and Indoor.
In the case of Outdoor the type of antenna is omni directional (isotropic) with 0-to 2
dBi typical gain, or wide beam with up to 8 dBi gain, and is installed on a mast to
cover shadowed, outdoor, areas within the normal coverage area of the Base
Station. This antenna must be installed to provide a minimum separation distance
of 1 m (100 cm) from persons within the area
In the case of Indoor coverage the power is split to several, omni directional
(isotropic) antenna with 0-to 2 dBi typical gain, and distributes to different indoor
areas (in building floors, tunnels, basements, parking lots, shopping centers etc.).
Typical specifications: gain: 2 dBi, VSWR: better than 2:1, Impedance: 50 ohm. At
least 4 such antennas must be connected to the BDA using cables and splitters. In
this case the max. EIRP from each antenna will not exceed 3W so that the minimum
required separation distance from persons within the area is 20cm.
