Patent ID: 11502709

Abstract:
This embodiment discloses a dual-band signal booster for a public safety radio network. The signal booster disclosed herein performs a low-noise amplification and a frequency down/up conversion on a radio frequency signal received from a donor antenna, amplifies the amplified and converted signal to a high-power level, and transmits the amplified signal to a service antenna. Further, the signal booster disclosed herein performs the low-noise amplification and the frequency down/up conversion on a radio frequency signal received from the service antenna, amplifies the amplified and converted signal to a high-power level, and transmits the amplified signal to the donor antenna. According to this embodiment, it is possible to simultaneously service a plurality of channels to increase a communication capacity. Further, it is possible to variably set a class, frequency and bandwidth of each channel as needed, which makes it possible to provide communication qualities optimized according to installation field conditions.
