UmSITE-TM3

The UmSITE-TM3 is a cost-efficient tower-mounted GSM solution for a wide range of applications, including:

  • Rural networks
  • Private networks
  • Rapid deployment networks
  • GSM related research and development

You can start building your network from a single UmSITE-TM3 and expand it to a nationwide network.

This tower-mounted base station may serve as a simple BTS or a complete network-in-the-box (NITB). As a NITB it integrates BSC, MSC, HLR, VLR and SMSC core network components. External connectivity is provided by VoIP (SIP) for voice and SIP and SMPP for SMS.

The UmSITE-TM3 has two independent TRX, each with 3W RF transmit power (6W total).
