The first Machine-to-Machine (M2M) applications can be traced back to World War II, and the ability to have machines “talk” to each other (via data communication networks) is essential for monitoring and controlling assets within homes, businesses, and even critical national infrastructure projects of today.
The nation's new billion-dollar epicenter for fighting global cyberthreats sits just south of Salt Lake City, tucked away on a National Guard base at the foot of snow-capped mountains. The long, squat buildings span 1.5 million square feet, and are filled with super-powered computers designed to store massive amounts of information gathered secretly from phone calls and emails.
Embedded wireless networks are one of the fastest growing applications, outpacing the overall semiconductor industry, due to the rapid uptake of embedded wireless communication in the form of smartphones and portable medical devices. Embedded wireless networks are also found in automobiles, enabling smarter safety features, better engine performance management, and as networked infotainment devices
The global economy is on the upswing in 2013, which means semiconductor companies have a great opportunity to reap the benefits. According to analyst firm IHS, revenue is expected to grow 6.4 percent this year after two straight years of decline. As a result, semiconductor professionals are asking themselves two questions: How can we take advantage of this growth, however brief it might be? And what happens if the economy takes a plunge...
Before there was Edward Snowden and the leak of explosive documents showing widespread government surveillance, there was Mark Klein — a telecommunications technician who alleged that AT&T was allowing U.S. spies to siphon vast amounts of customer data without warrants.
