GSMA Mobile World Congress 2013


With more than 1,700 companies exhibiting their latest products and services, seen by a record 72,000 visitors, the GSMA’s Mobile World Congress in Barcelona was a rousing success. In addition to showcases like the Connected City, which featured a complete urban environment, “powered by mobile,” there were a plethora of new gadgets, including waterproof phones, glove-friendly touch screens, 3D printed phone cases, and more.

Since NFC (Near Field Communication) was the buzz throughout the show, it seemed appropriate that the show also featured the NFC Experience, a collection of SIM-based NFC services for attendees. According to the GSMA, participants were able to create a virtual NFC badge on their handsets to speed their access into Congress. NFC-enabled smart posters around the venue provided access to information and services.

Also of note: the BBC News/Technology reported that the GSMA predicts mobile operator data revenues will overtake voice revenues globally by 2018, and that health-related applications will perhaps be the most popular, saving hundreds of billions in medical costs.

Uncertain Times for DefenseWill OpenRFM Shake Up the Microwave Industry?
By Barry Manz

Throughout the history of the RF and microwave industry there has never been a form factor standardizing the electromechanical, software, control plane, and thermal interfaces used by integrated microwave assemblies (IMAs) employed in defense systems. Rather, every system has been built to meet the requirements of a specific system, which may be but probably isn’t compatible with any other system. It’s simply the way the industry has always responded to requests from subcontractors that in turn must meet the physical, electrical, and RF requirements of prime contractors. Read More...
