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

The growing demand for radiocommunications calls for higher frequencies since all lower-range frequencies have already been allocated worldwide

Soon you will begin to hear about wireless sensor networks used everywhere in Asia, from farms to factories. What are they?

In the last of a three-part series on interference in wireless systems, we look at all the different types of potential interfering signals and how to identify them

With wireless technology such as Wi-Fi becoming ever more popular and commonplace, Sean Casey from Intel takes a look at the year that really saw it take off and at the trends for the coming years

Wireless has been well received ever since the first wireless radio transmission over the Atlantic Ocean by Marconi almost a century ago. Since that time the technology has been harnessed to suit myriad applications
