Radio over IP (RoIP) in its simplest form is the ability to transmit radio signals over internet protocols, which allows communication over local area networks and diverse wide area networks (WANs) of wired and wireless networks such as mobile and satellite.
RoIP has many use cases at the tactical edge, for example:
- Facilitate two-way radios of Push-to talk to communicate on a global range.
- Communicate with a diverse set of end-user devices (EUDs) .e.g. mobile phones, laptops, etc.
- More robust operations and resilient communications by extending land mobile radio (LMR) capabilities to communicate over satellite.
However, at the tactical edge a key advantage of RoIP is the ability for coalition partners to communicate. However, a common challenge is to bridge the gap between the partners who have different radio types.
VoyagerEMm – a TrueTactical™ radio gateway
VoyagerEMm is a low-SWaP (runs on 2 watts of power) radio gateway and is part of the Voyager m-series. VoyagerEMm was developed for operators to close the communication gap between partners using different Land Mobile Radios (LMR). The VoyagerEMm supports connecting up to four donor radios via RJ45 radio ports.
With the VoyagerEMm, operators have the flexibility to connect multiple LMRs:
- With a dedicated IP stream of SIP / Unicast / Multicast Audio
- Bond the LMRs together to act as a broadcast station.
- Bond and/or Trunk LMRs to Voice over Internet Protocol (VoIP) networks and telephone lines.
With four RJ45 radio ports supporting Press to Talk (PTT), volume controls and Squelch (SQL), operators can easily support communication among different users, groups, or agencies using different radio types.
Furthermore, with VoyagerEMm’s built-in compute, operators can use the VoyagerEMm as a standalone server to connect multiple radio groups. With support for multicast, unicast RTP and SIP, VoyagerEmm can work alongside 3rd party call management solutions that support the same protocols.
When paired with the Voyager m-series compute module, the VoyagerVMm, operators can support a wide range of 3rd party call management solutions at the tactical edge.
Tactical radio integration – bridging the RoIP gap
The Voyager tactical radio integration kit (Voyager TRIK-M) is a holistic solution for the deployment of battalion wide communications that supports all the radios required for operation across the battlefield and coalition partners.
TRIK-M integrates the VoyagerEMm alongside a wide range of radio brackets that protect and power radios from leading vendors such as L3 Harris, Thales, Viasat, Collins, and MANET providers.
RoIP for multi-lingual coalition deployments
In a multi-nation deployment, it is often the case that English is not the first language. However, with Voyager TRIK-M, operators can deploy Voyager compute modules on which AI powered translation services e.g. Instant Connect Enterprise (ICE) or CISTECH MACE (Mobile AD-HOC Communications Environment) can be used to affect mission understanding outcomes.
As an example, VoyagerVM 4.0 supports hardware accelerated inference, making it faster to convert english based text and voice to multiple languages. With the Voyager TRIK-M it has never before been easier to bridge the understanding gap in C2 operations among multi-lingual coalition partners.
Conclusion
VoyagerEMm is a TrueTactical radio gateway, designed to fit the hand of the warfighter. With minimal power requirements and weight, VoyagerEMm lightens the load that forward based signal operators need to carry. With VoyagerEMm go anywhere with LMRs and maintain resilient communications that truly have a global reach.
