Towerstream Announces Deployment of Alvarion(R) Mobile WiMAX(TM) Equipment in Chicago Network

CHICAGO and MIDDLETOWN, R.I., Oct 01, 2008 /PRNewswire-FirstCall via COMTEX News Network/ -- Alvarion's FCC Certified BreezeMAX(R) 3650 solution brings enhanced wireless broadband services to businesses in downtown Chicago

Towerstream (NASDAQ: TWER), a leading fixed WiMAX(TM) service provider, today announced it is now delivering WiMAX service to businesses in downtown Chicago using the 802.16e BreezeMAX(R) 3650 solution from Alvarion (NASDAQ: ALVR). The addition of this FCC Certified solution to Towerstream's existing network will enable the company to reach additional businesses in the city and ensure Towerstream's customers continue to receive optimal service.

"Adding Mobile WiMAX equipment to our existing Chicago network is an important step to not only ensure our customers are receiving optimal high-speed, wireless broadband service, but also to prepare our network for the future as WiMAX technology continues to emerge and evolve," said Jeff Thompson, President and CEO of Towerstream. "Installing 802.16e compliant technology from Alvarion enables us to take advantage of the economies of scale that Mobile WiMAX offers, while helping us bring our customers the speed, bandwidth and reliability they expect from Towerstream."

The addition of Alvarion's Mobile WiMAX gear provides Towerstream with non-line-of-sight capabilities. As a result, the company can now offer its high-speed, wireless broadband service to additional businesses in downtown Chicago that did not previously have line-of-sight to a Towerstream Point of Presence (PoP). Towerstream is able to provide this enhanced service to businesses of all sizes in the area, while utilizing its existing network infrastructure and equipment.

"By adding Mobile WiMAX equipment to its network in Chicago, Towerstream continues to demonstrate leadership in the quickly evolving wireless broadband market," said Greg Daily, President of Alvarion, Inc. "Alvarion's equipment enables Towerstream to maximize WiMAX's potential in terms of cost, coverage and enhanced services."
