New Wireless Data Standard Threatens 3G
It is no secret that wireless operators are struggling to deliver on the much-hyped promise of next-generation networks that combine voice and data on cellular networks. Collectively, they have spent billions on licenses and equipment to roll out a broad array of new data-centric services for customers. But emerging technologies could offer a leap past so-called third-generation (3G) systems just as they are getting off the ground.
One such technology is the nascent IEEE 802.20 standard, a member of the 802 family that includes the better-known 802.11b, or Wi-Fi . The Wi-Fi LAN (local area network) standard has proliferated in recent years by offering broadband wireless connections for laptops and other mobile devices.
