Radio Solutions

Terrestrial Trunked Radio (TETRA) is a digital trunked mobile radio standard developed by the European Telecommunications Standards Institute (ETSI). The purpose of the TETRA standard was to meet the needs of traditional Professional Mobile Radio (PMR) user organisations such as those listed below.

The air interfaces, network interfaces as well as the services and facilities are specified in sufficient detail to enable independent manufacturers develop infrastructure and radio terminal products that would fully interoperate with each other. For example, radio terminals from different manufacturers can operate on infrastructures from other manufacturers.

The ability for full interoperability between different manufacturer's products is a distinct advantage of open standards developed by ETSI. As the TETRA standard is supported by several independent manufacturers this increases competition, provides second source security and allows a greater choice of terminal products for specific user applications.

Because the TETRA standard has been specifically developed to meet the needs of a wide variety of traditional PMR user organisations it has a saleable architecture allowing economic network deployments ranging from single site local area coverage to multiple site wide area national coverage.   Besides meeting the needs of traditional PMR user organisations, the TETRA standard has also been developed to meet the needs of Public Access Mobile Radio (PAMR) operators.

ROIP (Radio Over Internet Protocol)...

 User devices connect to base stations, and base stations connect to IP gateways. At the IP gateway, software CODECs   sample and transcode the voice communication into IP packets. The transcoded voice stream is transmitted through   Internet links to one or more other gateways, where it is converted into the special language of that device, enabling the   various devices to talk to each other. So, for example, a P25 public safety radio has its air interface converted to IP,  passed along wires or fibre optics to another gateway and converted into CDMA or GSM for cell phones. The ability for  devices to speak to other devices is managed through a system of virtual talk groups. Software manages user access  rights, talk controls, and talk group membership. This allows for users to be added to, or removed from, a talk group in  near real time using a computer mouse and a simple drag and drop functionality. Because of the IP backbone, a user  may be connected to a talk group regardless of their physical location.



is  it secure?

IP-based systems enable dynamic interoperability across disparate communications devices by securely linking the appropriate devices for the duration needed. Intelligent software allows those with authority to connect devices, monitor usage, assign privileges and monitor conversations. RoIP systems support high levels of security through encryption, user and device authentication, secure user login, and use policies. The security in the IP section of the communications doesn’t change whatever security there is in the over-the-air portion of communications

what are the benefits of RoIP?

Internet Protocol-based radio interoperability provides a number of benefits to emergency response organizations. Some advantages enabled by RoIP include:
• Complete interoperability with current communications equipment, from P25 radios to legacy systems, across multiple frequencies.
• Secure talk group connections between radios and any other communications device including land line phones and computers.
• Dynamically scalable communications platforms allowing users to control who is on talk groups, assign listen-only privileges, monitor conversations and users present, and remove users from a talk group, all in real time.
• Geographically independent communications, with remote control over interoperable talk groups and the ability to join physically distributed users.
• Enriched media - such as images, and maps - delivered through IP enabled devices

What are the caveats?

While traditionally achieving radio interoperability meant buying a new radio system, RoIP separates the issue of interoperability from the issue of new equipment. With RoIP, users can connect nearly any communications device to any other communications device. However, RoIP is not a replacement for new radio systems. It does not add coverage or handset features. IP-based systems should be considered part of your emergency communications toolkit – not the whole thing.

How is RoIP related to Core Services?

RoIP systems use the IP and SIP standards, among others, so connecting competing systems isrelatively easy if the agencies, CODECs, and gateway addresses are known. But with thousands oforganizations with radio systems, where does this information reside? How do you connect with anorganization you may not have known before the emergency occurred? Core Services are shared toolsthat benefit all emergency agencies by enabling interoperability across emergency response domains and jurisdictions. The two Core Services of Agency Registry and Identity Management store an agency’s contact information and the rules of who can link radio systems/form talk groups for what areas. By accessing the Core Services when an emergency strikes, different RoIP products (as well as data communications products) can access the information they need to enable interoperable communications.
