Repeater General Information and Safety Precautions
1-13
The repeater receives the basestation signal via an external antenna see Figure 1-3. This signal is
amplified and filtered by the repeater and ultimately retransmitted via a second antenna. The entire
process is duplicated for the reverse path where the handset signal is amplified and filtered and
retransmitted to the basestation. This technique provides PCS coverage inside buildings or in
outside areas that previously did not have sufficient signal strength.
