Outsourced systems - a higher price to be paid
From these sectors our industry has adopted many business approaches that have provided real benefits for users, manufacturers and service providers
[ + ]EMC for functional safety
Electronic technologies are increasingly used in equipment that has an impact on safety. Unfortunately, all electrical and electronic technologies are inherently prone to suffering inaccuracy due to electromagnetic interference (EMI)
[ + ]Generating frequency agile and custom waveforms
There is considerable interest in generating complex waveforms to test radar and communications systems. An arbitrary waveform generator (AWG) is one of the most flexible methods of signal simulation
[ + ]Radio set to bounce into 2006 and beyond
Recent natural and man-made disasters have demonstrated the importance of radiocommunications to the basic functioning of society. In spite of many beliefs that the mobile phone would spell the demise of two-way radio, the industry is buoyant with growth
[ + ]Vertel & Kenwood take a walk in the sky
As the 25th tallest freestanding structure in the world, Sydney Tower (also known as Centre Point Tower) stands as a testament to the Australian innovative spirit
[ + ]Wireless revolution is coming down the line
A British rail operator is on track to expand its wireless internet service across its entire fleet of trains. The plans will transform every GNER train into a 'mobile office'
[ + ]Ensuring the best use of spectrum
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
[ + ]Ban Ni-Cads now and protect the planet
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
[ + ]Putting rail back on track
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.
[ + ]Underground system gets it all together
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
[ + ]More power and name change to GS1
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 opens second eye across Tasman
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 boost their vision
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
[ + ]A cable is a cable, is a cable - is not
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 tracked measurements
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
