Radio over IP

Flexible solutions for both analogue and digital radio. Interconnecting radio users, dispatchers and systems

Radio over IP (ROIP) Solutions

Radio over IP (RoIP) leverages modern digital technology to offer a cost-effective means of interconnecting radio systems and operators. It is a solution that enhances and adds value to both existing radio communications networks, and newly established channels.

Transitioning to RoIP offers some tremendous benefits to organizations that rely on two-way radio communications, which can easily be obtained on either legacy analog networks or digital through the use of IP gateways for radio.

Common RoIP Applications

Interoperability and Flexibility are two of the main benefits of Radio over IP or RoIP networks. Due to the flexibility of RoIP, there is a virtually endless list of combinations which you can choose. Contact us today to see how RoIP can add value to your network.

Interconnect Multiple Digital and Analog Radio Types

By using a gateway infrastructure you can also connect operators on PC consoles to radios of multiple radio types: analog or digital; conventional or trunked; open-standard or proprietary. The DRG range digital radio gateway can be programmed with a wide variety of digital protocols whilst the IPR range can connect analog radios to the same network. 

Operator Access to Remote Radios

By using IP gateways, operators on PC-based or hardwaredispatch consoles can connect to Analog Radios across a LAN or WAN without the need for backroom equipment. The transmit and receive audio, along with the PTT and Busy/COS signals, are transported over the link transparently. SELCAL, ANI and DTMF are also transported reliably, regardless of the level of compression that is employed.

Radio to Phone Connectivity

The IPR110+ SIP compatible gateway provides a connection to a private SIP PBX or to a public VoIP service provider. This diagram shows how the radio connected to the IPR110+ becomes an extension on the SIP server’s database. It is given a phone number that enables calls to be routed between it and the PBX or the PSTN. Phone users accessing the radio network are able to make PSTN calls by keying pre-defined DTMF or SELCALL strings.

Replace Leased Lines or a UHF/VHF Link

Two or more radios can be connected back-to-back over an IP link. This can typically be used to interconnect repeater sites over a Wide Area Network. The PTT and COS signals are transported over IP as data messages. The IP gateway will then  provide a configurable output to the radio.

Radio Bridging across IP

The IPR range of gateways can support radios on multiple frequency bands. Each IPR unit is linked to a common multicast group address. When one transceiver receives audio, voice packets are transmitted to this multicast address. Any other IPR unit that is linked to that address will accept those VoIP packets and re-transmit the audio to its respective radio.

Introduction to SIP for Radio

SIP is an IETF driven protocol that has revolutionized telecommunications. It is a signalling protocol that controls multimedia communications sessions over IP. Its sole purpose is to negotiate, setup and tear down the sessions whilst the actual multimedia communications is carried-out by other protocols such as VoIP.

Historically, two-way radio was considered an adjunct to the corporate communications system and was treated as an independent system, isolated from the broader corporate communications infrastructure. To provide interoperability between users of the radio network and other communications systems (including other radio systems) required the installation of special bridging and patching equipment.

Whilst this works to a certain extent, it doesn’t make it easy for an organization to streamline the flow of communications through-out its workforce. To enable an organization to achieve maximum levels of collaboration and productivity, it needs to unify its communications mediums, regardless of whether they are digital or analog radio, PBX, mobile phones or PC’s.

However, just having “IP connected” radios doesn’t mean that an organization can achieve unified communications. That’s why SIP needs to be an integral part of VoIP gateways and adapters.

Benefits of using SIP with Land Mobile Radio:

1. Able to Interact with Broader Communication Mediums

Radio over IP gateways/adapters that are SIP compliant enable the connected radio system to interact with a broader range of corporate communications mediums, without worrying about proprietary technology. In such an organization, subscribers on handheld portables or vehicle mounted radios can communicate with people who are not normally connected to the radio network. As an example, calls can be made between radio users and office staff with SIP compliant telephones. More recently, there has been a proliferation of soft-phones that are also SIP compliant. Omnitronics is starting to see applications where this level of unified communications eliminates the need for office staff to be desk bound and dramatically increases productivity.

2. Offers Dynamic Configuration

Radio over IP devices that are SIP enabled provide greater flexibility within radio networks because SIP makes it possible to structure these networks so that they can be re-configured dynamically. This applies to both user calls and inter-site links. For example, radio calls can be made to specific destinations, on demand. This brings efficiency to a network from both the IP and radio traffic viewpoints. SIP also allows links between radio sites to be managed such that link paths can be re-configured to meet specific operating needs.

IP Connectivity Methods

There are a number of methods of connecting Radios over IP and this will depend on your IP network. The table below explains the Advantages and Disadvantages of each of the methods.

Unlike many competing products, the Omnitronics’ Range of IP Gateways  support all the below connectivity methods. Contact Us if you have any questions about your particular network requirements.

Digital Radio Gateways

Omnitronics’ Range of Digital Radio Gateways provide organizations with a range of benefits  including added security, redundancy and flexibility.

See Also: Why use an IP Gateway for Digital Radios?

The gateways operate as an interface between Omnitronics’ dispatch solutions and a digital radio such as a MotoTRBO mobile, a DMR repeater or a P25 base.  Whether your organization is running different digital radio systems (including DMR, P25, Tetra etc) or a combination of them, it doesn’t matter.

The Digital Radio Gateways translate voice and data into the same digital protocol, meaning differing radios and protocols will all be able to connect to the one network. Users are no longer restricted in their choice of protocol nor need to convert their entire network in one swoop. True interoperability is now within reach.

DRG100

The original Omnitronics Digital Radio Gateway uses proprietary hardware and operating system software to provide a secure, reliable and flexible gateway between dispatch console IP networks and radio IP networks.The gateway forms a natural firewall between the two networks and provides an unsurpassed level of flexibility for integration into your IP infrastructure.

A P25 version is also available with the vocoder included at the gateway, eliminating the need for a vocoder at every operator position.

DRG200i

The DRG200i is designed to address the need for accessing both channels on Tier II (Conventional)digital radios such as DMR, NXDN and dPMR. It will interface into controllers, repeaters and base radios that support an IP console interface such as DMR–AIS. The device can simultaneously and independently receive from and transmit to both channels.

IPR110+

The IPR110+ carefully combines VoIP & SIP technologies to enable dynamic connections to remote radios making radio communications more accessible and easy to use.  

The IPR110+ is used for two main purposes:
1. Providing radio network coverage to SIP phone users
2. Extending telephone coverage to rugged or difficult locations that are best accessed through wireless communications.

The gateway enables users to connect to remote radio networks from their existing office based SIP compatible PBX systems and, at the same time, it gives users of two-way radios the ability to dial SIP phones or telephone extensions from the field.
The powerful IPR110 Plus builds on the features of the highly regarded IPR100 by providing remote RS-232 channel change and higher levels of security.

The real power of this device comes from the product’s ability to manage connections with SIP phones and SIP compatible PBX systems. This product is perfect for organisations requiring occasional access to a radio network using SIP Phones.
