Trade Lead Description:
A cell phone booster http://www. wirelessphonejammer. com/cell-phone-jammer/product_jdetv445px3yc445wcncl55520097185484859.html, a type of bi-directional amplifier (BDA) as commonly named 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 cellular broadcast towers used to broadcast by the
network providers, but are much smaller, usually intended for use by one building. Modern cellular repeater amplifiers work by rebroadcasting cellular signals inside the building.
There is a good cell phone booster (www. wirelessphonejammer. com) website there. The systems usually use an external, directional antenna to collect the best cellular signal, which
is then transmitted to an amplifier unit which amplifies the signal, and retransmits it locally, providing significantly improved signal strength. Posted from China - Beijing on 7 October, 2009
