The CSIRO is using some of the latest radio technologies to ensure that the most is made of the spectrum and that users are given the high-speeds of data transmission that they want

Many of us dedicate our working lives ensuring the health and safety of society, or we support those who put themselves on the line, day in day out, because we value the security they provide to our communities

While Australia's railways continue to be riddled by different, often incompatible communications systems, the efficiency and continued development of the network are at risk. Antoine Rouot of Nortel discusses a new digital radiocommunications system.

A trunked radio system in Bangkok's underground railway enables the system to carry out maintenance, deal with emergencies, give train information to passengers and tell the control centre where the train is via induction loops laid in the tunnels

A name change and the grant of a 4 W licence were two of the highlights of the EAN's (now GS1 Australia) Impetus 2005: Vision in Progress: Global Standards and RFID conference in Melbourne

TIGER - the Tasman International Geospace Environment Radar - is taking a much larger bite at southern skies following the opening in February of its second radar base in Invercargill, New Zealand

Radio astronomers at Britain's Jodrell Bank Observatory, working with colleagues from Europe and the US, have demonstrated a technique they say will revolutionise the way they observe

The ubiquitous coaxial feeder cable provides the RF link on mobile base stations from Melbourne to Minneapolis. Bought by the metre, its 'buy and install' cost is negligible on the total base station price scale

Frequency selective devices such as amplifiers, filters, directional couplers, attenuators and the like are characterised by their performance versus frequency. Measuring these characteristics is performed by various methods, most are frequency swept

Radio communications between emergency services has reached a point where it is essential that political games and technical wrangling must be put aside for the common good

With microprocessors now part of the radio scene, the need to monitor system voltages with a power-on reset (POR) ensures proper initialisation at power-up. Joe Chong of Maxim begins a two-part article on monitoring and sequencing supply voltages

For most electronic systems, monitoring system voltages with a power-on reset (POR) ensures proper initialisation at power-up

In recent years, the Asia-Pacific region has bucked the global trend of declining telecom growth. The uptake of mobile services and popularity in many territories has seen significant growth in both subscribers and network infrastructure

Back in 1912, the Reverend John Flynn became acutely aware of the needs of people living in outback Australia. The community facilities that we now take for granted in our cities simply did not exist in the outback back then (and often still don't today)

My dictionary tells me that an antenna is an insect's feeler or an aerial. This article will take a how and why look at aerials as devices used for sending and receiving radio waves
