MR400 Series CDMA Repeater is a CDMA Repeater for CDMA cellular signals.
1)used for small area coverage
2)easy to install and free of maintenance

Our CDMA Signal Amplifier provides an affordable solution to solve the indoor coverage problems due to signal fading and attenuation caused by architecture obstacles.

 

The CDMA Signal Amplifier is mainly deployed for small points of in-building wireless signal coverage, when installation of standard repeaters will generate great interference to the wireless network or the area to be covered is widely distributed. Its easy installation and maintenance can help carrier get fast return.

 

The CDMA Signal Amplifier works as a relay between the BTS and mobiles. It picks up the strongest signal from the BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

Mini Repeater

 

Features for Mini Repeater

 

  • Super-compact size with light weight to facilitate wall-mount installation;
  • Low power consumption and no interference to BTS;
  • Smart Automatic Level Control (ALC) ensures output level stable and adjustable continuously;
  • Unique color LEDs to indicate power supply and signal level of uplink and downlink;
  • Linear power amplification to effectively suppress intermodulation and spurious emission;
  • "Plug & Play" - basically no needs for configuration and free of maintenance.

 

 

Application for Mini Repeater

 

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

  • Small blind area or weak-signal area, e.g. underground or semi-underground rooms, small basements, underground parking lots;
  • Small zones with hot traffic: meeting rooms, supermarkets, offices, pubs, coffee shops, gyms, etc.;
  • Elevators (especially when cabling in the elevator shaft is difficult);
  • Private homes or villas at outskirts with bad signal coverage.
