Radio Interoperability includes the use of Radio over IP – RoIP

Catering for centralised or decentralised network structures, the radio interoperability solution provided by Omnitronics has been proven in a variety of operating environments including emergency dispatch centres, oil and gas operations and the transportation industry.

Audio Bridging Interoperability

The 619 range of Audio Bridges are a group of products that provide a uniform way to interconnect radio equipment from different manufacturers and in different bands. Typically, Omnitronics’ Audio Bridges are used to interconnect multiple repeaters together at a remote site and to provide multiple paths within a radio network providing ultimate interoperability.

This ability is paramount to the mission of all organizations that are involved in providing a service to our communities. However, radio networks can become so complex that providing interoperability can seem daunting.

The Omnitronic’s range of Audio Bridges makes this simple, providing you with the choice and flexibility your organization requires. In addition, our Audio Bridges are used for Rebanding and Narrowbanding to make the transition simple without any downtime.

The Omnitronics’ range of Audio Bridges includes:

  • 619DSRI – This sophisticated eight-port digital bridge provides the highest level of functionality including the ability to dynamically re-configure radio networks to suit operational requirements.
  • 619EI – These devices offer the most affordable and simple way to interconnect disparate radio systems.

Why Interoperability?

Interoperability is vital to many organizations and is often mentioned as one of the key reasons to go with one product or solutions over another. However, this term can be quite ambiguous as the range of interoperability can vary significantly.

Omnitronics strive to give organizations complete interoperability and flexibility from between frequency bands to full inter-agency cooperation across protocols.

Frequency Interoperability

Often organizations require multiple frequency bands to manage their communications. Take the example of an Oil Rig. They may require marine band to talk to passing ships, air band for helicopters and UHF or VHF for personnel on the platform itself. Ideally all of these parties should be able to communicate with each other quickly and easily. By adding Audio Bridges to your network, this is made possible. This technology also makes Rebanding and Narrowbanding simple, without any downtime.

IP Phone Interoperability

By adding SIP compatibility to your network through IP gateways, phone users are able to access radio networks from their desks or even from their smart phone.

Analog and Digital – Phased Migration

A common hesitation many organisations have towards upgrading their radio networks to digital is the significant time and cost associated with changing over all their radios at one time. This is especially complex when there are radios spread across large geographical areas.

By using a combination of IP gateways across your radio network, RediTALK or Alto dispatch operators can communicate to all radio users no matter if they are operating Analog or Digital radios.

This means that organizations can gradually phase the upgrade of their repeater sites over multiple budget periods and that over the course of the migration everyone can keep talking to each other.

As far as the dispatch console operator is concerned, their screen will look the same regardless of the protocol. It won’t matter to them what is under the hood, just what functions are available to them on any particular channel. For example, the digital channels may have the option of individual calling whilst the analog channels may have the option for Selcall.


Digital Systems Interoperability: DMR (TDM), Digital FDM, TETRA and P25 Interoperability

Digital Mobile Radio (DMR) provides professional organizations with an affordable and simpler choice in digital systems. Developed by the European Telecommunications Standards Institute (ETSI), DMR offers multiple tiers of complexity for differing communications needs.

This flexibility and the wide choice in certified manufacturers such as Hytera, ICOM, Kenwood, Motorola, Simoco and Tait has resulted in DMR becoming the fastest growing digital radio solution.

However, so much choice can be confusing and that’s where Omnitronics can help. We have worked directly with many of the above Radio Manufacturers to create the DRG100 gateway that can interconnect them into one common network.

By using this approach, a number of benefits are achieved by DMR users:

  • Multiple protocols (both analog and digital) and manufacturers can be used on the same network.
  • Radios can be accessed simultaneously by a Mixture of Dispatch Consoles.
  • The cost and complexity of the Dispatch GUI is reduced by loading time critical and proprietary functions to the Gateway.
    Organizations have the flexibility to Change Protocols or Radio Manufacturers.
  • 3rd Party Integrators such as IP Voice Recorders can interface to the Omnitronics network, not all the differing interfaces.
  • Some functions such as GPS have not been defined by ETSI to date and therefore differing manufacturers use proprietary interfaces for this which Omnitronics has incorporated.
  • The DRG100 offers higher network functionality such as the ability to do conferencing and multicasting to suit the application and the IT environment.

Omnitronics has developed a range of interfaces for differing DMR manufacturers, including both proprietary and DMR—AIS standard features. Depending on the manufacturer, we also offer the additional choice of connecting via both Donor Radio and via IP.


Radio over IP (RoIP) Solution

Why Use an IP Gateway for Digital Radio?

As digital radios already operate over IP and gateways have historically been used to connect analog radios over IP networks, a question regularly arises about why you would need a gateway such as the DRG100 for digital radios.

Below we discuss the 5 Key ways in which RoIP gateways add value to Digital Radio Networks.

  1. Saves Costs - Gateways allow radios with Point-to-Point Protocols to be shared amongst a number of operator positions.
  2. Flexibility - Networks can easily be added to and expanded when Radio over IP gateways are used.
  3. Networking Choice - Many IT departments require particular network configurations in order to utilize the wider IT environment and often the networking choices for a base station or node controller are limited. By adding a gateway to the equation organizations are provided with much more networking choice such as the ability to do conferencing or multicasting.
  4. Greater Interoperability - A mixture of radio types (Both Analog and Digital) can interconnect on the one network. This helps support migration or connectivity to networks where analog is still required in some environments.
  5. Simpler Maintenance - Changes in proprietary consoles such as loading time critical and proprietary functions are more easily managed and confined to the Gateway, meaning the GUI does not need to be upgraded. This significantly reduces cost and upgrade time when multiple users exist.
