Wideband Code-Division Multiple Access, deployed in 5 MHz increments; AT&T launched in US in 2004. Wireless Fidelity, refers to 802.11x networks; Although an Ethernet LAN protocol, it functionally provides 3G services in localized "hotspots." Most major carriers offer WiFi options with their cellular data service plans. 802.11b is the most common, offering up to 11MB data rates. Other 802.11 standards (a,g,n) offer enhanced data rates, more reliable and broader coverage. Worldwide Interoperability Microwave Access, deployed on licensed and unlicensed spectrum. Provides high-throughput WiMax broadband connections over long distances; implementation of the IEEE 802.16 standard, provides metropolitan area network connectivity at speeds up to 75 Mbps. Can transmit signal 30 miles. Mobile Videoconferencing and Interactive Multimedia The 3G mobile phones of the 21st century are just beginning to take advantage of sophisticated broadband capabilities and will pave the way for the imminent development of a new breed of personal communicators. With speeds reaching 384K bps, nearly three times faster than basic rate ISDN, for fast moving mobile terminals and even higher speeds for users who are stationary or moving at walking speed, 3G systems are changing the way we communicate, access information, work, and interact socially and personally. To get perspective, consider that global 3G sales and services revenues are expected to exceed $9 billion in 2005. Other research concludes that by the year 2008 there will two billion mobile users worldwide and that 3G networks will carry traffic from more than one billion of these and account for two-thirds of global cellular service revenues. In the early 1990's, consumer mobile phones were designed to enable and enhance Person-to-Person communications and-despite their initial size, cost and limited coverage-have forever changed the way people interact. In just over a decade, mobile phones went from a nice accessory to THE critical mode of personal communication and an indispensab
