System measures multiple tags and tests new antenna designs
A system capable of simultaneously measuring hundreds of RFID tags and rapidly testing new RFID tag prototypes has been designed by researchers.
[ + ]Frequency 'sweet spot' helps signals travel in tunnels
Underground tunnels, usually a difficult environment for radios, can have a frequency 'sweet spot' at which signals may travel several times further than at other frequencies, according to researchers at the National Institute of Standards and Technology (NIST), in the US.
[ + ]Where we could be going with radio
This look at what could happen in the future with radio services is taken from a presentation by Chris Chapman, ACMA chairman, when he addressed nearly 300 delegates at the RadComms conference in Melbourne.
[ + ]Wireless networks that build themselves
Wireless sensors in embedded systems in devices from traffic lights to mobile phones, designed to create wireless communications networks automatically, could benefit a range of areas, including emergency management, security, helping vulnerable people to live independently, traffic control, warehouse management and environmental monitoring.
[ + ]Wide-range astronomy antenna
A new antenna structure that works in a wide range of frequencies has been presented by researchers from Carlos III University of Madrid (UC3M) in collaboration with the National Astronomical Observatory in Spain.
[ + ]Is RF a danger to health? – Part Two
This is the second part of a multi-part series looking at various RF effects including sperm count, interruption of sleep patterns and brain tumours. Researchers at the Cleveland Clinic in America studied 361 men at their infertility clinic to investigate the effect of mobile phone use on semen quality.
[ + ]What’s in store for RFID in 2008?
RFID has been moving ahead in leaps and bounds according to reports released throughout 2007. However, what is in store for 2008? Will RFID technology continue to move forwards or will another technology surge ahead and steal the limelight?
In a recent interview with Radio Comms, Asia-Pacific, Scott Austin, president Syscan Australasia, shed a little light on the subject.
[ + ]Is RF a danger to health? - Part one
Over the years there have been ongoing concerns, scare stories and many reports on the possible harming effects of RF emissions, particularly in relation to mobile phones
[ + ]Underground mine radio - Sending signals through rock
A radio system operating at just below 1000 Hz has been designed to send and receive emergency text messages to miners working underground
[ + ]Double antennas double the signal
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
[ + ]Magnetic GPS tracking unit
Private investigators listen up: MagneticGPSTracker from the USA has launched a low-cost, easy-to-install magnetic covert GPS tracking system
[ + ]Telemetry brings distance closer
With the growing acknowledgement of global warming and the effect it has on our climate, in particular our precious water resources, there is now more than ever a realisation of the importance of water conservation
[ + ]They came, they saw, they conquered
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.
[ + ]Radio makes cords obsolete
New research at the Georgia Institute of Technology could soon make that tangle of wires under desks and in data centres a thing of the past
[ + ]Another sell-out dinner!
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.
