Glossary of Terms
Repeater or
Cell Enhancer A Radio Frequency (RF) amplifier which can simultaneously
amplify and re-broadcast Mobile Station (MS) and Base
Transceiver Station (BTS) signals.
Band Selective Repeater A Cell Enhancer designed for operation on a range of channels
within a specified frequency band.
Channel Selective
Repeater A Cell Enhancer, designed for operation on specified channel(s)
within a specified frequency band. Channel frequencies may be
factory set, remotely set by computer, or on-site programmable.
BTS Base Transceiver Station
C/NR Carrier-to-Noise Ratio
Downlink (D.L.) RF signals transmitted from the BTS and to the MS
