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.

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.

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.

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.

Increasing complexity has long been a major embedded systems developer concern. Some industries have seen this trend earlier than others but it appears none will escape the trend. It is just a matter of time until this is a concern across every market segment.

SIP (session initiated protocol) technology, developed for IP communications, has moved radio communications from being an isolated system to being truly unified with the broader communications infrastructure allowing for communications between digital and analog radio, PBX, mobile phones, computers and more.

The ACMA’s field operations section has many responsibilities, including the role of identifying and resolving interference to radiocommunications services. Recently, the team received notice of interference to the new 6.8 km CLEM7 tunnel in Brisbane. An ACMA team was assembled to investigate the issue.

Cumberland County, Tennessee’s PlantCML COR^P25 land mobile radio network in the US includes a Zetron Advanced Communication radio dispatch system. It is providing the county with improved 9-1-1 emergency dispatch functionality and better radio coverage and interoperability among the public safety agencies it serves.

I keep on saying it and now I’m going to say it again - RadioComms Connect was the busiest, the biggest and the best in its relatively brief four-year history. From small beginnings it has grown to last year’s size that even forced onto the concourse of the stadium two companies. But they didn’t seem to worry as people passed to and from on their way to the presentations.

Radio Communications Solutions is a professional sales and service two-way radio company that has been servicing central and northern Queensland since 1999. It offers a range of products and sells and services most major brands, including Motorola, Icom, Tait, GME and Uniden.

The ACMA has released details of forthcoming changes to the 400 MHz band following its extensive review. These changes are likely to affect operations of two-way radios, and the Australian Radio Communications Industry Association (ARCIA) has issued a statement that, it says, clarifies some of the points raised by the authority. Headed ‘ACMA changes to radio licences’, the statement goes on:

Traditionally, the basic mobile communication requirements of underground mines have been analog two-way voice radios and low-speed data links. With the tremendous development of open standard data communication products, safety and monitoring systems and protocols for wired and wireless applications, TCP/IP and 802.11 are now the de facto standards. These standards have paved the road for the realisation of the mines’ high-speed communications systems.

In a move to improve system reliability and flexibility, while providing a platform for mobile data capability, KiwiRail, the organisation responsible for managing New Zealand’s rail network, has begun a major upgrade to the nationwide radio system used to help the safe movement of trains and track workers around the country.
