37dBm 460MHz Channel Selective Digital TETRA Repeater with 12.5KHz Bandwidth


Digital Repeater Introduction:

The Digital Repeater GW-37DR-T is the simplest method to extend the coverage area by amplifying the incoming signal. The Repeater supports uplink/downlink configuration in channel selective mode to let RF engineer have much flexibility and security to plan for their coverage network. Since the installation environment for Repeater may be critical. The Digital Repeater is used IP65 cabinet with effective heat sink design to let the unit operate safety in both indoor and outdoor environment. In addition, GW-37DR-T can do remote supervision though RF modem or Ethernet. 


Digital Repeater Features

◇ High linearity PA; High system gain;

◇ Support multi operators' network simultaneously

◇ Intelligent ALC technology;

◇ Full duplex and high isolation from uplink to downlink;

◇ Automatic Operation convenient operation;

◇ Integrated technique with reliable performance;

◇ Local and remote monitoring (optional) with automatic fault alarm &remote control;

◇ Weatherproof design for all-weather installation;


Digital Repeater Applications

    To expand signal coverage of fill signal blind area where signal is weak or unavailable.

    Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.

    Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots etc.

    It 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 ‐75dBm;

    And can meet the requirement of antenna isolation to avoid self‐oscillation.

When you choose the channel number.

Please note,

460 + (N * 0.0125) = 460.9125MHz,

N is channel number. N = 73


460 + (N * 0.0125) = 461.1125MHz,

N is channel number. N = 89
