As the largest event in the industry, IMS is the place where component, subsystem, and service providers make their biggest annual announcements and showcase their latest, most exciting technologies. In case you missed the show, here is a selection of some of the innovative new products that were on display at IMS2014.
The nascent Internet of Things (IoT) movement promises to drive a relentless shift towards an interconnected network of devices. According to research firm Gartner, the growth of the IoT will far exceed that of other connected devices and will grow to 26 billion units by 2020, representing an almost 30-fold increase from 2009. This article explains why the ultimate success of the IoT will depend on active support from satellite networks.
Frequency deviation (fDEV) — the peak frequency change, above and below the unmodulated carrier frequency — is a critical parameter of FM. Therefore, it is imperative to accurately measure fDEV. The Bessel Null Method is a simple way to verify fDEV accuracy — in a way that is not dependent on the fDEV specs of any signal generator — with excellent precision and high confidence.
The best crystal oscillators are capable of very low phase noise, but a number of pitfalls await the unwary system designer, any of which can seriously degrade the oscillator's performance. Some of the more common design issues are discussed in this article.
