The multi-mode UHF/VHF data radios will be used for both legacy analog and advanced digital needs for GE's LOCOTROL system for railway systems.More>>

Power consumption is a central design consideration for wireless sensor networks whether they are powered using batteries or energy harvesters. Vital to success for either approach, however, is the need for hardware that uses power intelligently.More>>

Using robust radios coupled with a variety of sensors, geophysicists in Ecuador have implemented real-time monitoring systems for the country's volcanoes and other seismically active areas, leading to improved knowledge and public safety.More>>

Cathodic protection devices have been used for decades to monitor steel pipes for corrosion. A new family of radios is designed to automate this process, connecting directly to the corrosion monitoring system.More>>

A survey of more than 700 IEEE Fellows, done by the Institute of Electrical and Electronics Engineers in conjunction with the Institute for the Future, sought to learn what science and technology developments are most likely to take hold within the next 10 to 50 years.More>>

Beef is big business, more than $50 billion/year, in fact. So, it goes without saying that tracking cows is important, especially in the wake of BSE (bovine spongiform encephalopathy a.k.a. mad cow disease) and other animal diseases. The USDA is developing the National Animal Identification System...More>>

There was significant channel congestion and the wireless systems didn't always function as the exhibitors had hoped.More>>

Last month you got me started on building a direct sequence spread spectrum (DSSS) transceiver. You covered the transmitter discussion and promised to come back to explain the receiver and error-correction code.More>>

It's clear that developers see RFID-and-sensor networks as a key growth area. A sampling of recent developments in tags (sidebar) and infrastructure prove it.More>>
