Cognitive radio allows spectrum sharing
01 May, 2009In the event of a disaster, the emergency services have to be able to trust communication networks. But what happens if the network is overloaded or even off the air as a result of the disaster?
Spectrum licensing review
27 April, 2009The Australian Communications and Media Authority has released a discussion paper as part of a review of the technical frameworks that apply to spectrum licences.
Millimetric radio may speed data transfer
05 August, 2008Researchers 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.
Tiny nanotube antennas may yield better signals
08 January, 2004In the future, mobile phone calls and television pictures could become a lot clearer thanks to tiny antennas thousands of times smaller than the width of a human hair. At least that's the speculation of a University of Southern California researcher who has been investigating nanotube transistors.
