At the heart of the system is an...
My dictionary tells me that an antenna is an insect's feeler or an aerial. This article will take a how and why look at aerials as devices used for sending and receiving radio waves
[ + ]Measurement accuracy up to 50 GHz and higher
The growing demand for radiocommunications calls for higher frequencies since all lower-range frequencies have already been allocated worldwide
[ + ]Wireless sensors: a new computing era
Soon you will begin to hear about wireless sensor networks used everywhere in Asia, from farms to factories. What are they?
[ + ]Identifying an interferer by the characteristics of its signal
In the last of a three-part series on interference in wireless systems, we look at all the different types of potential interfering signals and how to identify them
[ + ]The year of going wireless
With wireless technology such as Wi-Fi becoming ever more popular and commonplace, Sean Casey from Intel takes a look at the year that really saw it take off and at the trends for the coming years
[ + ]The place of wireless
Wireless has been well received ever since the first wireless radio transmission over the Atlantic Ocean by Marconi almost a century ago. Since that time the technology has been harnessed to suit myriad applications
[ + ]Open interfaces at the wireless frontier
Tremendous industry cooperation has been behind the creation of the AISG open standard communications protocol; the development has much import for the future of cellular infrastructure
[ + ]Status and potential of 802.16a WiMAX
The IEEE 802.16a standard, approved in January 2003, provides wireless last-mile broadband access over the frequency bands between 2 and 11 GHz, a range that enables non-line-of-sight performance
[ + ]Emergency call centre partnership for Victoria
Like many state and national governments around the globe, the Australian state of Victoria privatised its government-owned utilities in the late 1990s. Among the assets was an entity known as the National Response Centre (NRC)
[ + ]RFID: Changing the way we work with data
Radio frequency identification (RFID) is the new generation of automatic identification and data capture. These wireless systems allow for non-contact reading and are effective in manufacturing and other hostile environments

[ + ]Making the piezo effect as clear as crystal
The piezoelectic effect is defined that pressure applied on quartz crystal generates voltage and voltage applied across crystal quartz produces mechanical vibration
[ + ]Conquering that 'last mile'
Pioneering work by physicists and engineers at ANU to build a cheap, simple and robust wireless communication system may soon see regional Australia getting a workable connection to the Internet
[ + ]Manufacturers need to find value in RFID applications
RFID has major applications in supply-chain management, but those burdened with implementation costs don't receive much of the value. Manufacturers need to find ways to benefit from RFID technology other than forced compliance
[ + ]HF radio bridges the gap between peacekeepers and NGOs
Peacekeepers and NGOs are confronted with many similar communications problems when they find themselves in trouble spots where public order has broken down
