Recent emergency situations have arisen in Britain, including severe flooding, extreme weather and even terrorist attacks. These have highlighted, repeatedly, just how vulnerable some sections of society can be in such circumstances. Now British researchers, writing in the International Journal of Emergency Management suggest that wireless could hold the key to remedying this problem.

Operating railways safely has been of paramount importance since the earliest days of steam locomotion. How to ensure that a driver can not only see but act on a signal aspect has always been top of the list of requirements. Now radio is providing a means of reducing human failure as this story of US experiences shows.

Two radio links - one to a mine and the other to a construction site - have allowed broadband communications where there was practically no coverage before.

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.

Imec presented several solutions for 60 GHz communication at the recent International Solid State Circuit Conference in the US.

Altair Semiconductor and Aeroflex have formed a joint long-term evolution collaboration.

Remote central locking is among the most convenient aspects of modern motoring. Transmission of the radio signal that activates the system is not particularly secure, however. A new encryption technique increases security without draining the key’s battery.

The primary remit of public safety communications is to provide a safe and secure environment to allow people to go about their daily business. This goal is not something that changes with the country, although the approaches taken and solutions required will differ as the geographical area and population density varies from one market to another.

The launch of the International Centre for Radio Astronomy Research is a boost to the Square Kilometre Array (SKA) project.

The ACMA’s field operations section has a broad range of responsibilities and undertakes a number of activities around Australia, including signal monitoring, compliance investigations and identifying and investigating domestic and radiocommunications interference. The section has also been engaged to take measurements for the digital switchover.

Last September, the ACMA released a discussion paper seeking views on possible changes to regulatory arrangements for VHF marine radio used by recreational boat operators.

Antenna technology is in a constant state of change as performance requirements get tougher and systems become more complex. This has two important consequences. First, more testing - and more test data - is required to validate and verify system performance. Second, that testing must be completed in less time and at lower cost to help ensure timely and profitable completion of in-spec systems.

A radio system that tells bus drivers about road accidents and traffic jams has been set up in Changchun, the capital city of Jilin province in north-east China.

Berkeley Varitronics Systems has released a handheld mobile phone detector fittingly called the Bloodhound that enables security officers to scan real time for unauthorised mobile phone activity in correctional facilities and detect the precise location of the caller using a direction-finding antenna.

The National Institute of Standards and Technology and partners from industry and academia have designed and tested experimental antennas that are highly efficient and yet a fraction the size of standard systems with comparable properties.
