GPS Weakness Could Sink Wireless

A timing expert from the National Institute of Standards is concerned that the ease with which GPS signals can be jammed could spell trouble for wireless networks, as well as many other commercial endeavors, in the coming years.Dr. Marc Weiss of the Time and Frequency division of the US National Institute of Standards and Technology (NIST) laid out his concerns at the recent Mobile Network Security Strategies conference in New York City. Weiss said that wireless networks increasingly require pinpoint accurate timing to synchronize transmissions between basestations and deliver faster connectivity, and they rely on global positioning system (GPS) signals from satellites to deliver that data.
