Making better use of the spectrum

26 May, 2010

A digital radio system that is designed to make more efficient use of the spectrum will use a 6.25 kHz bandwidth and have increased range.


Major changes planned for 400 MHz band

01 December, 2009

The identification of a harmonised government band to facilitate interoperability between government agencies, particularly the police, security and emergency services, was one of the major proposals contained in a consultation paper presented at the RadComms conference in Sydney in April.


Radio map may tune in wave of innovation

30 June, 2009

In one of the most detailed radiofrequency mapping projects ever carried out in Britain, one technology innovator is undertaking the first Britain-wide radio spectrum monitoring for Ofcom, the independent regulator and competition authority for British communications industries with responsibilities across TV, radio, telecoms and wireless services.


Averting spectrum saturation

26 May, 2009

Mobile users want better video calls, streaming television and faster downloads, placing more demands on the limited radio spectrum available to operators. Could handsets that intelligently sense their radio environment and opportunistically grab free bandwidth be a solution?


Cognitive radio allows spectrum sharing

01 May, 2009

In 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, 2009

The 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, 2008

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.


Tiny nanotube antennas may yield better signals

08 January, 2004

In 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.
