A Cellular Distributed Antenna System (DAS) is a network of antennas strategically placed throughout a building, venue, or area to enhance and distribute cellular signals. The purpose of a Cellular DAS is to improve the coverage and capacity of wireless communication networks, ensuring a strong and reliable signal for mobile devices within a specified area. Active DAS consists of three-stage system, that is:

Applications :

  • Airports
  • Road tunnels
  • Railway tunnels
  • Subway and tramway tunnels
  • Shopping malls
  • Hotels
  • Convention centres
  • Hospitals etc.

Point of Interface (POI):

  • Supports Wideband frequency from 700 to 3800 MHz as one product.
  • Supports Multi Operator, Multi Technology
  • Local control via USB and web based Remote management.
  • POI shelf has 8 plugs in dual-band RF cards. Each RF card supports up to 2 BTS ports.
  • Up to 16 different BTSs can be connected.
  • Maximum input power - DL: +43 dBm; UL: -10 dBm
