What is WIMAX?

WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m).
With WiMAX, WiFi-like data rates are easily supported, but the issue of interference is lessened. WiMAX operates on both licensed and non-licensed frequencies, providing a regulated environment and viable economic model for wireless carriers.
WiMAX can be used for wireless networking in much the same way as the more common WiFi protocol. WiMAX is a second-generation protocol that allows for more efficient bandwidth use, interference avoidance, and is intended to allow higher data rates over longer distances.
The IEEE 802.16 standard defines the technical features of the communications protocol. The WiMAX Forum offers a means of testing manufacturer's equipment for compatibility, as well as an industry group dedicated to fostering the development and commercialization of the technology.
WiMax.com provides a focal point for consumers, service providers, manufacturers, analysts, and researchers who are interested in WiMAX technology, services, and products. Soon, WiMAX will be a very well recognized term to describe wireless Internet access throughout the world.

Why would I use WiFi over WIMAX?

All wireless networks are not the same.
Wi-Fi is a wireless LAN technology and operates in unlicensed spectrum over fairly short ranges – up to a few tens of meters. Wide-area wireless technologies, like GSM, UMTS, CDMA, EV-DO (a CDMA technology), and WiMAX, just to name a few, operate on licensed spectrum reserved to a given carrier. These have a range of perhaps many kilometers, but, as is always the case with wireless, the further you go, the slower you go due to fading of the radio signal itself.
While Wi-Fi is subject to interference, there's a lot more spectrum available to it than is the case with cellular, and Wi-Fi spectrum is free as opposed to the big bucks – and high monthly fees – associated with wireless WANs. Tradeoffs, tradeoffs, tradeoffs. In reality, though, the two technologies will ultimately work together seamlessly – that's what fixed/mobile and mobile/mobile convergence are all about. You be hearing a lot more about these over the next few years, and eventually you won't know which wireless technology you might be using at any given moment in time.

Indoor Positioning and Navigation – The Next LBS Frontier?
We frequently hear and read about navigation and positioning along the highways and byways, but what about “indoor positioning”? In areas where GPS doesn’t work - inside a building, like a mall - what can you use to find your way? How might someone find you if disaster strikes and you are trapped? Tristian Lacroix, the vice president of business development for IndoorLBS.com, provides an update on the technologies and applications that have bubbled to the top after years of research and trials.
