Cyber Telecom - GSM / Cellular Repeater Boaster
A gsm
repeater, cell phone repeater, or wireless gsm signal booster, called a
bi-directional amplifier (BDA) in the wireless telecommunications industry, is a
device used to boost the cell phone reception to the local area by the usage of
a reception antenna, a signal amplifier and an internal rebroadcast antenna.
These are similar to the gsm broadcast towers used to broadcast by the network
providers, but are much smaller, usually intended for use by one building.
Modern gsm repeater amplifiers work by rebroadcasting gsm signals inside the
building. The systems usually use an external, directional antenna to collect
the best gsm signal, which is then transmitted to an amplifier unit which
amplifies the signal, and retransmits it locally, providing significantly
improved signal strength. The more advanced models often also allow multiple
cell phones to use the same repeater at the same time, so are suitable for
commercial as well as home use.
Other
advantages of gsm repeaters include an increase in the cell phone's battery life
and a lower level of radiation emitted by the handset - both caused by the lower
power required to broadcast the signal to the local bi-directional amplifier,
due to its proximity to the phone.
