IP INTEROPERABILITY SOLUTION
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 E&M analog interface allows easy connection to the IP
network using a simple router or VoIP gateway.
When connected to the IP network via a router or VoIP gateway the Ritron RadioNexus™ enables compatible
LMR radios to communicate across the IP network to any
Markets:
• Local, State, and Federal Government
• Businesses
• Schools, Colleges, Universities
• Retail Operations
For over 27 years, Ritron has been designing and manufacturing a wide range of wireless solutions. They include portable and mobile 2-way
r
adios, base stations, radio extender repeaters, radio callboxes, telemetry systems, voice alarm reporters and OEM transceivers.
Ritron recommends a supported Cisco router model 2651XM, 3725 or 3745
with the following installed options NM-HD-2V, VIC2-2E&M.
For enhanced communication capability with other network devices and LMR radios, Ritron recommen ds the WAVE (W
V
oice Environment) software application from Twisted Pair Solutions. For a whitepaper on LMR integration go to

other networked device (i.e. PC, laptop, IP phone, cell
phone) including two-way radios regardless of 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 with 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. Features include:
PC programmability, rugged, all-steel, heavy-duty
construction, 2 Watt transmitter, Automatic “ON” feature,
CTCSS or DCS signaling, wide or narrow band operation,
BNC connector for external antenna, local speaker, local
microphone jack, small and compact size (only 1.4”H x 3.8”W
x 5.6” L), wall or desk mountable, 110 VAC or 12 VDC
operation.
VHF “License-Free” models are available

RadioNexus® Application
Benefits:
• 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.
