Bridge VoIP and Radio Networks
Transport and switching networks have experienced explosive growth thanks to low-cost fiber optic cable and ubiquitous data gear. Radio networks, however, have evolved much more slowly, with legacy radio infrastructure still in heavy use today.
Radio Gateway solutions bridge the chasm between IP-based networks and various radio nets. Interoperability between unlike technologies is supported for:
- Land Mobile Radios (LMR), Air Ground Radios, etc.
- Military radios
- HF, VHF, and UHF radio nets
- VoIP endpoints
- SIP/AS-SIP trunking
- T1, E1, E&M, and LSRD trunking
- Fixed line/PBX subscribers
- REDCOM Sigma® Softphone for Android™ with PTT
With the ability to bridge radios into both legacy and VoIP networks, radio users have global access to Command & Control centers, smartphones, softphones, public networks as well as 3G, 4G, and VoLTE users.
An Intelligent Radio Gateway
Sigma® XRI is REDCOM’s intelligent Radio Gateway solution, and it’s far more powerful than a simple converter box. REDCOM Sigma XRI includes full switching, routing, and conferencing capabilities coupled with radio features such as:
- Flexible PTT and PTS controls
- VOX and COR
- Tunable 4-wire TX/RX audio interfaces
- Audio Monitoring
- Secure Radio over IP
- Interoperability with mobile clients
Connecting Public Safety and Military Radios with IP devices
Public safety organizations often face communications interoperability challenges when arriving at the scene of an incident. A single emergency event might involve many departments and individuals including fire (P25, Analog, VHF), sheriff (P25, P1, UHF), police (P25, P27/800), park police (DMR), participants with LTE phones, and emergency managers in an office far away from the scene. Differences in waveform, band, channel, or trunking may prevent these organizations from communicating with each other.
The problem is no different at the tactical edge. Warfighters working alongside Non-Government Organizations (NGO), Joint, and/or Coalition forces encounter serious challenges communicating with each other due to the varying signal and communications paths employed by each entity.
REDCOM solves these interoperability challenges with Sigma XRI, a low-SWaP C2 platform with voice, video, chat, and radio interoperability in a single tiny box. By connecting up to four donor radios directly to the XRI-400, users can instantly bridge the gap between disparate radio networks, endpoints, or frequencies, allowing for seamless communications between organizations. Additionally, Sigma XRI-400 allows radio users to communicate directly with users on any SIP end device (e.g. SATCOM, VoIP phones) and can even participate in voice conferences.
