Radio over IP

Radio over IP allows a number of push to talk radio handsets to be connected locally into an existing SIP based voice switching network including:

  • CISCO Call Manager or Juniper VoIP

  • Asterisk PBX

  • WAVE 5000 from Motorola (formerly WAVE from Twisted Pair)

  • Commercial SIP based VoIP PBXs

The push to talk network can interface with existing VoIP handsets, can connect calls onward to desk phones or cellular phones and to specialist PTT applications for Android or iOS  

Vocality's various radio-based solutions provide an answer to common radio connectivity and compatibility challenges.

Beyond Line-of-Sight (LOS) 

Devices such as Vocality RoIP, BASICS Radio Relay or BASICS Hybrid allow the direct connectivity of several handsets into the unit, and the push to talk radio conversation and associated signalling is converted into IP.

Unlike a straightforward gateway application, the Vocality units have a special functionality that cannot be found in other gateways. Vocality's PACE functionality allows the radio calls to be extended over IP with the maximum reliability, but the minimum of bandwidth overhead.

A combination of silence suppression, packet aggregation, de-jittering and efficient but clear voice compression bring significant bandwidth savings to the network operator, and importantly, the calls are clearer and more reliable to the user. In this way, users can extend a PTT radio network over -

  • Mobile satellite terminals (Thuraya IP+, Inmarsat BGAN)

  • Field deployed tactical IP (via line of site connectivity, satcom or fiber)

  • Terrestrial IP (extend radio networks for ambulance, taxi or emergency comms)

 

Cross-banding interoperability

Connecting multiple radios on different bands into a Vocality solution, different radio networks can be cross-connected.

By using this solution, different agencies or blue light services can have an easy and effective way to interconnect their service, removing the possibility that their services cannot work together in the case of an event. 

 

Remote Control

Using either in-band E&M signalling, or by using a data circuit (sync or async) carried alongside the radio extension or gateway, remote radio networks can be controlled from a central location.
