GSM 900 MHz Signals Booster Repeater for Mobile Phones
The Booster can strengthen the GSM signals at your premises; no more drop calls or experiencing poor mobile phone calls! Background
GSM mobile networks are everywhere around the world but depending on where a mobile phone is located, regrettably the quality of the GSM signals differ significantly from excellent to poor. The item in auction is designed to address the signals strength issue by boosting the signals in two directions (Full Duplex) :
1. signals transmitted from a mobile phone are received by the signal booster over the air via the booster's indoor antenna and these signals are amplified and retransmitted over the air via the booster's outdoor antenna to a nearby cellular phone base station.
2. signals transmitted from a cellular phone base station are received over the air by the booster via the booster's outdoor antenna and these signals are amplified and retransmitted over the air via the booster's indoor antenna to a mobile phone.
The GSM Booster can be viewed as an intermediate agent to help to set up a reliable wireless link between a mobile phone and the GSM mobile networks infrastructure.
Applications:
The Booster is particularly useful in zones with poor GSM coverage such as basements, car parks and tunnels. It can also be used in offices, homes, supermarkets, cinemas and hotels etc.
It is specifically designed for indoor uses.
Design
The Booster employed advanced filtering technology to reject the out of bands signals in the amplification stages, this results in crystal clear voice communication for an established GSM call as the GSM uplink and downlink signals are effectively isolated . Its AGC (Automatic Gain Control) mechanism ensures an optimum power is provided for the cell phone site as well as the mobile phone; all these are performed without user's intervention.
How the Booster benefits you
Reduce drop calls and improve GSM voice communication quality.
