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.
The ACMA is implementing some measures to remove regulatory barriers to spectrum trading and leasing, and to provide better information to radiocommunications users.
Jim2 Business Engine software is an integrated job tracking and accounting business management system for communications applications that reduces administration and keying errors.
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.
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:
The ACMA has completed licensing for spectrum for mobile telecommunications services at more than 2000 sites throughout regional and remote Australia.
C4i has brought into service the ninth of 20 fire control centre SwitchplusIP systems being delivered to Aviation Rescue & Fire Fighting (ARFF) of Airservices Australia.
The Wavenis Open Standard Alliance is an independent, non-profit, technology standards organisation that was created in 2008 to open and standardise the technology. It is also responsible for managing the Wavenis technology roadmap.
The Australian Communications and Media Authority (ACMA) has finalised radiocommunications licensing arrangements to facilitate mobile communication services on aircraft.
The mini-PACCS on-site man-down system is designed for people working alone in industrial, healthcare, aged care, security and high-risk facilities.
Australian Satellite Communications and Cobham SATCOM have launched ReadyConnect, a portable, quick-deploy emergency response solution.
With the installation of Zetron’s series 4000 dispatch system and its series 3300 VoIP call-taking system, the emergency communication centre in Morgan County, West Virginia, is now equipped to deal with current and upcoming changes in public-safety technology.
TETRA is a radio system that is being widely used around the world in all sorts of applications. An opportunity to talk about these applications and the technology involved, and to display some of the latest equipment, was at the TETRA World Congress in Singapore.
The primary remit of public safety communications is to provide a safe and secure environment to allow people to go about their daily business. This goal is not something that changes with the country, although the approaches taken and solutions required will differ as the geographical area and population density varies from one market to another.
