Picture this frightening scenario: a lone fireman stranded in the middle of a burning building. He reaches for his radio, pressing buttons by touch, not sight, because visibility is down to inches. The only sounds he hears are his colleagues rushing to the scene, still too far away to be of any real help to him or the frail civilian he’s pulled from the flames.

Today’s immediate need is for radio interoperability. Standards, industry and government initiatives are addressing the issue, but not entirely and, arguably, not quickly enough. It is important that standards are developed, and the efforts to define them are invaluable.

Interoperability between different agencies has been highlighted as one of the key challenges to improve emergency services’ responses to incidents - ranging from accidents to natural disasters and terrorist attacks. Mark Ward, national business development manager for Airwave Solutions Australia, explains the benefits of taking a ‘service management’ approach to address this challenge.

This article introduces multipath fading and describes the results of experiments conducted by Alciom on short-range 2.4 GHz RF links in indoor environments.

As microprocessors get increasingly more powerful, so does the appetite for additional software functionalities. Size of embedded systems software increases every year, bringing new types of problems.

Historically, connectors designed specifically for distributing power have been comparatively slow to adapt to changing needs. This product segment had not attracted major investment in research and design for a variety of reasons, including relatively low sales volume, highly customised application requirements and possible liability issues.

The ACMA is seeking public comment on a second consultation paper.

Designing and developing a test system that has component and unpowered testing, device programming, radio signal analysis and calibration, and no operator intervention for production testing of a point-to-multipoint radio product used for remote supervisory control and data acquisition network applications, is the challenge.

Having gained tremendous momentum over a number of years, WiMAX is now widely viewed as a leading candidate for fourth-generation (4G) wireless data communication.

In the November/December issue of Radio Comms Asia Pacific, David Cox, operations director of Pacific Wireless Communications, took issue with the DMR bid to ‘take over the world’ of mobile radio in his article “DMR - is it the road to nowhere?” He argued that Tetra has largely already achieved what DMR is wanting to do so, following on from that argument, this article looks more closely at what the DMR standard is all about.

We’re all familiar with the old ‘break-fix’ model of service - it’s been the way of life for many years. It works well; it generates revenue and keeps you in business alongside hardware sales. The problem is that it’s a short-term solution for a long-term user.

In the November/December issue of RadioComms Asia-Pacific, David Cox, operations manager of Pacific Wireless Communications, took the DMR Association to task for what he described as a “pied piper” march to the “dream of digital utopia” and the new standards that may be adopted. The DMR has responded and this is its reply.

When NT police planned an $8.612 million closed-circuit television system to monitor trouble hotspots in Darwin, it deployed a self-healing wireless network designed by MIMP connecting solutions to manage 109 cameras covering 6 sq km of the city’s streets.

Having gained tremendous momentum over a number of years, WiMAX is now widely viewed as a leading candidate for fourth-generation (4G) wireless data communication.

Lyon-Saint Exupéry airport has selected Sepura Tetra terminals for its radio and communication needs following the recent deployment of a new digital communications system that replaced four legacy analog networks.
