  • Introducing Private Mobile Networks

  • Key Features of a PMN

  • Recent spectrum auction has provided the opportunity to create a private network in any geographic location, that exists separate from the GSM network

  • Whilst on campus, mobile phone users can call others without using their existing mobile provider (e.g. T Mobile, Orange etc)

  • Mobile phones detect the new network and utilise it to connect to other users on campus

  • Users can also use existing PABX or SIP gateway to make external calls, again bypassing the mobile operators network

  • Key Features

  • A PMN (Private Mobile Network) provides users with the ability to add existing mobile telephones to their own internal voice network.

  • PMN is a private GSM network available to users within a campus site.

  • PMN is available across a wide area linking sites within one network.

  • PMN maintains continuity even when the public network is not functioning.
