2.2 How Does It Work
The single-band indoor amplifiers operating within one band guarantee better
cellular service and reduce dropped calls by enhancing signal strength. The
in-building repeaters work combining with two antennas. One is donor antenna and
the other one is service antenna. The signals obtained from nearest cell tower by
donor antenna, will be filtered and boosted by amplifiers, and then, the amplifiers
retransmit the amplified signals via cable to a service antenna to give subscribers
better service. That is the downlink process (Tower to Cell phone), and vice versa for
uplink (Cell phone to Tower).
