HPC-G27 GSM900mhz Mobile Phone signal booster

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.    

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.

We provides signal boosters kits for any Homes, Offices, Cars, RV's, Boats and more. All amplifier kits come with Indoor and Outdoor Antennas, Cables, Power adapters and more.

Specification of HPC-G-27 Dual band repeater:

The installtion of the Repeater

Outdoor antenna ( for receiving the signal from the BTS ) + Cable ( transfering the received signal) + Repeater ( for amplifying the received signal) + cable( for transfering the amplified signal) + indoor antenna( for shooting the amplified signal), 

(Note : Omni indoor antenna is 3dBi,it can work with about 200m2 . If need repeater coverage larger area , need add more antenna,the HPC-G-27 Max can work with 10pcs indoor antenna.  ( when add antenna ,please remember to take splitters )

Installation Approaches:

Fix up outdoor antenna reception on housetop and point to signal tower

Connect outdoor antenna to 'outdoor' port in repeater machine through cable

Connect indoor antenna(s) to 'indoor' port in repeater machine through cable also

Plug power adaptor into AC power socket and finish installation

Technique Supporting:

If still no signal receipt after activated repeater, please check if outdoor antenna point to

signal tower or elsewhere have strong signal and check if strength achieve -70DBM.

If strength is not steady, please check if outdoor and indoor antenna are too close.

Please ensure the outdoor and indoor antenna have distance of 20 meters at least ,

with a wall between and net a same horizontal line
