OpenBTS implements a complete GSM stack for voice and SMS. It also supports GPRS and UMTS 3G data standards. With an off-the-shelf server and software defined radio (SDR), it is now possible to build your own mobile network. These networks can be used to support true fixed-mobile convergence, bring coverage to remote areas or experiment and innovate within the cellular network itself. Because OpenBTS converts all cellular signaling and media directly to SIP and RTP, the integration environment should be familiar.

In this webcast, you will learn:

  • How traditional mobile networks are architected and compare them to a new, IP focused, hybrid architecture
  • How to build a mobile network using Open Source software and hardware components
  • What non-traditional use cases exist for radio access networks and detail APIs available for future innovation
