Only for in-building applications
One must be aware that FCC regulation mandate that this repeater is to be used only for
in-building applications and thus feed passive or active DAS (Distributed Antenna
Systems) accordingly.
FCC RF Exposure Limits
This unit complies with FCC RF exposure limits for an uncontrolled environment. This
equipment can only be installed in in-building applications, driving passive or active DAS
systems. All antennas must be operated at a minimum distance of 30 cm between the
radiator and any person’s body.
Antenna Installation
Installation of an antenna must comply with the FCC RF exposure requirements. The
antenna used for this transmitter must be mounted on permanent structures.
The FCC regulation mandate that the EIRP of type B signal boosters should not exceed
5W.
Therefore the max antenna gain allowed for this type of signal booster should be limited
to the values given by equation (1) for the service antenna and equation (2) for the
donor antenna
Equation (1) - Max SERVICE antenna gain
Max SERVICE antenna gain (dBi) = 37 – (33dbi - # of antennas in dbi – cable losses in dbi).
For example:
No. of Antennas
Cable Losses
Max Allowed Antenna Gain
4 3 37 - (33-6-3) = 13dBi
1 3 37- (33-3) = 7dbi
10 3 37- (33-10-3) = 17dbi
Equation (2) - Max DONOR antenna gain
Max DONOR antenna gain (dBi) = 37 – (27dbi - cable losses in dbi).
