CDMA (Code Division Multiple Access) – Cellular protocol followed by Sprint PCS™, Verizon Wireless™, and Alltel™. Service is mostly isolated to North America. Here are the basics of how a cellular device works … a cellular phone is a short-range radio transmitter and receiver. The phone software converts the sounds from the microphone into small pieces of information (packets) that are transmitted by radio signal to the nearest cellular tower. From the tower, the pieces are digitized and transferred throughout the cellular network by fiber-optic cable. The pieces are then broadcast by the cellular tower to be received by a second phone, wherein the software pieces together the parts in their proper order and translates them into what we hear as a friend’s voice. In today’s world, wireless data transfer is also possible through many of the cellular phones available in the marketplace. The CDMA protocol involves a certain principle of packet formation and transmission such that information (both voice and data) can be sent over an extended range with less power. CDMA2000 is a “generational overhaul” over the original CDMA service.

Visiting Navx: An Inside View Into Auto Content Curation
Not long ago GPS Business News had the opportunity to spend two days at Navx’s “Content Factory“ in Bucharest, Romania. Navx, headquartered in France, offers content to car makers and GPS navigation vendors.The briefings at their Content Factory was an interesting experience that offered an insight view into their core business: providing verified, quality content to the auto industry: fuel prices, parking data and electric vehicle charging in tens of countries. Navx mixes automated data processing with a sizeable amount of manual verifications, i.e. between 5,000 and 8,000 phone calls are made per month to verify the data accuracy.
Best apps for navigating indoors: satnav without satellites
How to find your way around airports, shopping malls and other large indoor spaces.We all use satnavs, but they don’t work indoors. We investigate some apps and new technology that could help us find our way in airports, shopping malls and any large buildings. It’s a first-world problem, but a problem nevertheless: How do you navigate an indoor space when GPS does not work?  While it may not yet be ideal, as with everything these days, there’s an app for that – or rather several apps. President of the Royal Institute of Navigation, Dr Roger MacKinley, explained why GPS does not work for indoor navigation:
China to Join Effort on Aircraft Satnav Standards
Europe’s EGNOS augmentation system sharpens the accuracy and reliability of GPS signals so they can safely be used for landing approaches across a growing number of European airports. But aviation is a global enterprise — so the aim is to develop a seamless network of augmentation systems in future. That is the task of an international group of experts, the Satellite Based Augmentation Systems (SBAS) Interoperability Working Group (IWG), whose 27th  meeting took place in Tampa, Florida, September 8-10, hosted by the Institute of Navigation.
