Achieve a new level of interoperability and increase communication, safety and productivity by expanding your existing IP network to include your LMR two-way radio users (RoIP).

The Ritron RadioNexus™ network-ready LMR base station transceiver is available in VHF and UHF frequency band models. A built-in RJ-45 connector and Type 3 or Type 5 E&M analog interface allows easy connection to either an RoIP capable router or “radio gateway” connected to the IP network.

When connected to the IP network via a RoIP capable router or radio gateway the Ritron RadioNexus™ enables compatible LMR radios to communicate across the IP network to any other networked device (i.e. PC, laptop, IP phone, cell phone) including two-way radios regardless of their make, model, frequency band or signaling format (equivalent hardware/software may be required at opposite end). For even greater talk range and/or increased penetration in and around buildings, the RadioNexus™ can even be programmed to communicate through a radio repeater.

For maximum compatibility with other LMR radios the Ritron RadioNexus™ can be programmed to work with virtually any brand of VHF or UHF business band radios.

Ritron RadioNexus™ transceiver provides interoperability of VHF and UHF LMR radios as well as other non-radio devices over the IP network.

• Leverage existing investment in different types of communication networks e.g. IP, LMR radios etc
...all can be connected so they work with each other.
• Adds greater value to 2-way radio equipment - communicate with non-radio devices, radios in other bands, over longer distances.
• Better coordination, Safety, Security - allows monitoring of radio system traffic from virtually anywhere on the planet.
• Interfaces easily with other Radio Gateway/RoIP Router products and console application software products.
• Rugged, reliable, plug-and-play transceiver
• Low cost, economical
• MADE IN USA
