Radio over IP (RoIP) devices

Radio over IP is a cost effective way to interconnect radio systems. Radio over Internet Protocol (RoIP) transfers the analogue audio signals used by Land Mobile Radio/Repeater Systems, digitally over the LAN (or Internet). In addition to voice, RoIP also transfers signals that are specific to LMR applications, such as PTT and CORControl lines. It is a technology that enhances and adds value to radio communications networks. The key benefits are: network flexibility, cross-banding interoperability and lower costs

Key benefits

  • RoIP provides secure connection between different Radio Networks in different geographical locations and creates one Network for all. 
  • By using Telegrupp RoIP devices, it is possible to connect multiple radios on different bands into one cross-connected Network. We are able to cross-connect VHF and UHF, tactical radios and mobile radios. Different agencies and/or blue light services can have an easy and effective way to interconnect their service into one Network. 
  • Availability of equipment and decreasing costs of equipment
  • The system uses an existing infrastructure 

Typical applications

  • LMR (Land Mobile Radio) interoperability
  • Cross-banding interoperability
  • Remote control (operator access) of radios
  • Communication gateway between multiple digital and analog radios
  • Radio bridging across IP
  • Users: mining, construction, security, multi-radio sites, road and rail, aid agencies, oil and gas, military, marine
