4.4 RF EXPOSURE WARNING
4.4.1 General
In order to satisfy the FCC RF exposure requirements, it must be ensured that the
installation complies with the following requirements.
4.4.2 Donor Antenna requirements
The Donor antenna connected to the BASE port in the Repeater is usually installed
outdoor. This antenna has a very sharp beam (Yagi type or similar) pointed to the
BTS This type of antenna has 12-20 dBi gain. Cable and jumper loss is at least 2dB.
The Donor antenna must be installed to provide a minimum separation distance of
1 m from any personnel within the area.
4.4.3 Mobile Antenna requirements
The second antenna is connected to the MOBILE port in the Repeater. This interface
serves either an Outdoor antenna or an Indoor antennas array, in accordance with the
application.
In case of Outdoor application, the antenna type is omnidirectional (isotropic)
with 0 to 2 dBi typical gain, or wide beam with up to 10 dBi gain. This antenna is
installed on a mast to cover a shadowed outdoor area. Cable and jumper loss is at
least 2dB. Installation of this antenna must provide a minimum separation distance of
1 m from any personnel within the area.
In case of Indoor coverage, the output power is split into several, omni directional
antenna with 0 to 2 dBi typical gain, and distributed to different indoor areas (in
building floors, tunnels, basements, parking lots, shopping centers etc.). At least 5
such antennas must be connected to the Repeater with cables and splitters. In this
application, the maximum EIRP from each antenna shall not exceed 3W.
Consequently, the minimum required separation distance from any personnel within
the area is 20 cm. Less separation is needed if the power is divided into more than 5
antennas covering many floors or areas.
