In a typical broadcast transmission, radio signals bounce off objects in the environment, reaching the receiver over multiple paths. 'Multi-path' signals can produce fading and distortion resulting in temporary failure of reception
Savi Technology has begun deploying solar-powered RFID readers and signposts, enabling users in the defence and commercial sectors to conserve energy and reduce costs while tracking supplies in real time.
They came, they presented, they exhibited, they networked and they dined. They said they were "impressed", "delighted", they said it was worthwhile and then they asked where the 2008 event will be.
Held in conjunction with the RadioComms Connect 2007 conference, the ARCIA gala dinner brought together over 350 industry professionals, including manufacturers, suppliers, designers and system users, to celebrate the industry.
The VX-820 series of commercial handheld radios are IP57 submersible and come standard with a powerful 2000 mAh Li-Ion battery for long talk times. A 3000 mAh Li-Ion battery is also available. Designed for use in hazardous environments, the devices each exceed the military specification 810C/D/E/F. They are claimed to be the smallest digital APCO25 radios in the world.
Radio frequency tagging has reached the motor vehicle manufacturing industry but not just as a guide to warehouse parts: the latest tags are actually attached to components inside a working car
Smart and adaptive antenna technologies are entering a stage of full market acceptance, according to a report from West Technology Research Solutions (WTRS), a Silicon Valley-based research, publishing and consultancy company focused on emerging wireless technologies.
Macquarie University electronics PhD student Michael Boers has defeated competitors from universities in the US, Canada and Korea by designing and building an ultra-efficient radio frequency (RF) power amplifier.
Wearable, wire free and easy to set up do not usually describe devices that monitor heart rate and cardiac activity
Until now, the ability to perform multicasting over the internet has not been possible. Omnitronics has implemented a technique to overcome this issue to enable a number of radios to be linked together over the internet in a peer-to-peer arrangement. Once in operation, audio received from any radio will be transmitted to every other radio.
The first 42 radio dishes of the Allen Telescope Array (ATA) are working and collecting data from outer space, according to the University of California, Berkeley and the SETI Institute
IDS Microchip and austriamicrosystems have partnered to develop a UHF RFID reader IC targeted at the portable reader market. These readers would be used to interrogate Gen 2 RFID tags allowing contactless identification of goods or materials in a broad range of applications.
IDTechEx will stage the conference Active RFID and RTLS in Dallas, USA. The conference’s title emphasises the fast growing real-time locating systems (RTLS) used from hospitals to dockyards for locating people and assets.
