Alltel Wireless (NYSE: AT), America�s largest network, is now offering continuous Axcess Broadband coverage throughout the New Orleans and Baton Rouge metro areas, including along the north shore of Lake Pontchartrain. This next generation EVDO (evolution data optimized) technology provides customers with unlimited wireless access to the Internet at speeds comparable to wired broadband connections such as cable modem or DSL. Axcess Broadband makes it easy to surf the Internet, access e-mail and calendars and download large, graphic-rich files while on the go. Using the service, customers can access advanced business, news and entertainment applications from their laptops, smartphones or handsets at average speeds of 400 to 700 Kbps with maximum speeds of up to 2.4 Mbps. �Alltel Wireless is committed to meeting the growing data needs of our customers in New Orleans, Baton Rouge and surrounding communities,� said Joanna Miller, vice president of business solutions for Alltel Wireless in Louisiana. �Axcess Broadband wireless Internet service delivers an unmatched wireless broadband experience that will keep both traveling business professionals and casual users connected with the fastest and most reliable data services.� Axcess Broadband is now available in Slidell, Mandeville and Covington, as well as in Timberlane, Metairie and Kenner. The continuous service extends north of Baton Rouge to Port Allen, Scotlandville, Baker and Zachary. The new launch in southern Louisiana follows the introduction late last year of Axcess Broadband service in Monroe and Shreveport. Nationally, Alltel has introduced Axcess Broadband in metropolitan areas such as Tampa, Charlotte, Cleveland and Phoenix; in smaller cities such as Little Rock, Ark.; Raleigh, N.C., and Savannah, Ga., and in towns such as Grand Haven, Mich.; Dothan, Al., and Durango, Colo. The company plans to launch Axcess Broadband in additional markets across the country in 2007, giving it one of the largest EVDO footprints of any U.S. carrier. Axcess Broadband is available for $59.99 a month for unlimited use with qualifying voice plans. In addition to supporting a wide range of productivity enhancing business applications, it enables Alltel�s Axcess TV, with more than 25 channels, and XM radio, with 20 of the best satellite radio music channels. To experience the high-speed network, customers will need an EVDO-capable handset, such as the MOTORAZR V3c, or a laptop PC data card, such as the Kyocera Passport 1xEVDO PC Card.
