GSM 900M RF Repeater

Model
  • GSM 900M:  UNRG6

Description

Picture of GSM 900M RF RepeaterGSM 900M RF Repeater is designed to solve problems of weak mobile cellular signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Repeaters system is to receive low-power cellular signal from BTS via radio frequency (RF) transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.

According to your requirement for working frequency, you can choose either type of RF Repeaters:

  • Band Selective RF Repeaters System: to amplify all signals in the whole band (Various bandwidth is available upon request)
  • Wireless Channelized RF Repeaters System: to amplify only the signals transmitted by the customized 1 or 2 or 4 or 6 or 8 channel (A narrow band with customized central frequency)

Application
To expand signal coverage of fill signal blind area where signal is weak or unavailable.
  • Outdoor/Rural: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
  • Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots etc
The Single Band GSM850, CDMA800 RFR is mainly applicable to such case:
  • The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than -70dBm;
  • And can meet the requirement of antenna isolation to avoid self-oscillation.
