FOCUS State-of-Art Interoperability and Data Sharing


standards, with Project 25 ISSI and NetworkFirst, or at the subscriber level by incorporating multi- mode radios.


Raytheon offers enhanced interoperability for military and public safety operations with its Wide Area Interoperability System and ACU products. These enable fi rst responders operat- ing on different systems or frequencies the ability to communicate across entire regions and states. WAIS software easily integrates into existing sys- tems and allows users to control interconnected, on-site interoperability systems from any point on a network.


The ACU-1000 solution provides simultaneous cross-connection of different radio networks to telephone or SATCOM systems, as well as radio- over-Internet and voice-over-Internet talkpaths. The system connects up to 12 audio devices (and can be expanded to 24) and has the ability to in- terconnect radios in any band. ACU-2000 IP interoperability offers addi-

tional SIP capabilities that allow disparate communica- tions systems to be connected, monitored and controlled


over an Internet-based network. The local Interoperability Gateway provides SIP capability for full radio network in- teroperability, while the server-based version uses SIP to provide cross-connection capability for radios and other four-wire devices.


Motorola Solutions has also developed a system to en- sure enhanced communications among first responders operating on divergent systems. Motorola Solutions’ Moto- bridge capabilities are offered in both fixed and mobile ap- plications. Motobridge is a scalable, Internet-based system that builds on traditional components to create a flexible, dynamic interoperability solution for the public safety sec- tor. Its distributed architecture design allows each compo- nent to function independently in case of damage or loss of power.


Among the networks that can be supported for interopera- bility are two-way radio systems, Project 25 systems, telephone (IP, cellular and landline), Sprint push-to-talk networks, and radio systems from any manufacturer. Motobridge is also in- teroperable with MOTOTRBO™ radio systems and SMART- NET™, SmartZone™ and ASTRO® 25 systems. Motobridge offers an IP Dispatch application that allows network administrators to quickly set up communication with radio users via a simple graphical user interface. Pre- confi gured emergency communication plans are stored and easily activated with the click of a mouse. Effective joint re- sponse planning is achieved with the Virtual Control Head feature, which connects various dispatch control points and telephone users via full-duplex telephone conferencing.
