8.2 Tuning Procedures
The Base Station does not require any tuning beyond the adjustments
performed during manufacture.
As part of the Base Station installation process, a technician will
configure three variable attenuators in the transmit chain. These
attenuators allow the technician to compensate for the variable
transmission line loss and antenna gain associated with each PWAN
cell site installation.
