( Depend on the area condition) 2.One indoor antenna only use for about 50 ~100 square meters. (in open space).If want to make all use of 2000 square meters which the host supports, need to add more indoor antennas and power divider / splitter. The repeater makes the signal stronger in places with poor signal coverage such as: 1) Underground areas: basements, parking lots, tunnels; 2) Other places where cellular signal is shielded by metal or concrete walls offices, supermarkets, cinemas, hotels; 3) Places distant from the BTS like private houses. Steps that describe the work of Repeater. 1) The outside antenna receives the signal from the nearest mobile base station. 2) The outside antenna sends the received signal through the coax cable to the installed Repeater. 3) The Repeater accepts the low signal and improves it. 4) The improved signal goes to the inside antenna through the connection coax cable. 5) The inside antenna send the improved good signal to your mobile phone. Installation Approaches: 1) Fix up outdoor antenna reception on housetop or outside the window and point it to the signal tower. 2) Connect outdoor antenna to “BTS” port in repeater machine through cable. 3) Connect indoor antenna(s) to “MOBILE’ port in repeater machine through cable also. 4) Plug power adaptor into AC power socket and finish installation.
