Arcwave to Present MSO Case Study of Planned Deployment of ''Wireless Bridges'' at Broadband Wireless World Conference.

CAMPBELL, Calif. -- Presentation to Review Wide Open West's Planned Deployment of Wireless Plant Extension Solution to Reach Small to Medium Sized Businesses Unreachable by Wired Plant

Arcwave, Inc., the leader in providing wireless solutions for the cable industry, today announced that Chris Martin, vice president of marketing for Arcwave, will present a customer case study at the Broadband Wireless World Conference in Las Vegas at 8:30 a.m. on Friday, April 22, 2005. The presentation, "Wireless Opens New Markets for Cable Operators," will feature a review of how Wide Open West, the nation's 15th largest cable operator, will deploy Arcwave's ARCXtend wireless plant extension solution to offer high-speed Internet services to small to medium sized businesses (SMBs) within their service area.

Wide Open West recently completed a successful field trial of Arcwave's ARCXtend solution to customers in Illinois. The company plans to deploy ARCXtend units as a cost-effective alternative to T1 service for the numerous SMBs in their service area that are currently without affordable broadband service.

The presentation will review how wireless plant extension solutions can enable cable operators to leverage their extensive coax networks and advanced IP service capability to target a large portion of the domestic SMB high-speed data market, estimated at more than eight million businesses, that has been previously unreachable due to cost, regulatory or deployment delay considerations. While approximately 90 percent of the $100 billion SMB market for voice and data services is within close proximity to existing cable networks, an estimated 50 percent of the SMB market is currently not serviceable by cable operators due to zoning restrictions, "right of way" challenges and the expense of laying new fiber or coaxial cable in commercial areas.

The presentation will focus on how convenient "plug and play" wireless plant extension systems can seamlessly integrate into a cable operator's network and operating infrastructure to create a wireless bridge for the transmission of the cable industry's DOCSIS standard signals between the wired network and one or more customer sites at speeds significantly faster than DSL.

Broadband Wireless World will take place April 21-22, 2005 at the Caesar's Place Events Center in Las Vegas, NV.
