How spread spectrum could spread
Traditionally, telemetry and SCADA data radio users have opted for narrowband licensed channels, primarily for protection from possible interference sources and the security of bandwidth for critical infrastructure.
[ + ]Australian technology to provide live video link to Mars
When a manned mission is eventually sent to Mars, the whole world will be able to watch ‘live’ television coverage of the mission using the Deep Space Array Based Network Beamformer developed by an Australian research scientist.
[ + ]Antenna for ultra-wideband communications
Virginia Tech researchers have developed a compact ultra-wideband antenna for a range of home, motor vehicle, medical and military applications.
[ + ]How the latest analysers measure up
While it sometimes seems a little difficult to engender much enthusiasm among some of the more technologically jaded members of the radio communications profession, there seem to be very few things likely to bring out the little-kid-on-Christmas-morning attitude than laying hands on the latest and greatest device tool of the trade.
[ + ]Data system smoothes the journey
Dublin Bus, Irish public transport operator, has chosen Tait to carry out an upgrade of its existing communications infrastructure.
[ + ]Wireless sensor networks that organise themselves
Self-organising networks of wireless sensors are being used by researchers for a wide range of environmental monitoring.
[ + ]Wireless network monitors cows' health
A wireless measuring system, consisting of sensors and transmission units, helps to keep livestock healthier with a minimum use of resources.
[ + ]Tune in to RadioComms Connect for a great reception in November
It’s bigger, it’s better and it’s longer, and it’s unique in the Australasian two-way radio world. It’s RadioComms Connect 2008, which is back for its second year and set to take the radio industry by storm when it comes to Melbourne in November.
[ + ]Emergency communications via satellite
A 10 kg GSM mobile phone network has been developed by European researchers to allow rescue workers to set up communications hours, or even minutes, after a man-made or natural catastrophe.
[ + ]Wireless ocean monitoring
A marine wireless network has been developed by researchers at the University of Queensland to help manage the Great Barrier Reef and other sensitive environments.
[ + ]Luggage handling at Hong Kong Airport
A multi-year contract to supply Hong Kong international airport with up to 70 million RFID labels will see speedier and more reliable luggage handling for many of the 48 million passengers that use the airport each year.
[ + ]Millimetric radio may speed data transfer
Researchers have proved the viability of a new and as yet untapped radio frequency band which will increase the speed and capacity of data transfer to wireless devices like laptops and iPods, and potentially between a home DVD player and high-definition TV.
[ + ]The booming business of Active RFID and RTLS
The RFID business value is expected to grow by five times in the next 10 years. The Active RFID business is growing by about 10 times, driven by the $475 million military order for Savi Technology and innovations such as the first 100,000 RFID labels from Power ID that have greatly enhanced range over alternatives.
[ + ]Super strength signalling in marine and coastal regions
A particular window of time when mobile signals and radio waves are ‘super strength’ — allowing them to be clearer and travel greater distances — has been discovered by Salil Gunashekar as part of his doctoral studies at the University of Leicester’s Department of Engineering in England.
[ + ]Major changes to land mobile under discussion
Major changes to land mobile frequencies and modes of operation are up for consideration in two papers released by the ACMA (Australian Communications and Media Authority) just before its RadComms conference. The two discussion papers, ‘Spectrum Options: 403-520 MHz band’ and ‘Five-year Spectrum Outlook 2009-2014’ were of particular interest to many in the audience and came in for a good deal of discussion.
