DragonWave Solution Fuels Business Only Broadband's Expansion in Chicago and Into New Markets

DragonWave at heart of Business Only Broadband's multi-million-dollar Chicago upgrade and introduction
of services in New York

OTTAWA, ONTARIO--(Marketwire - Nov. 5, 2007) - DragonWave Inc. "DragonWave" (TSX:DWI)(AIM:DWI), a
leading global supplier of next-generation wireless networks, today announced that Business Only
Broadband, a provider of fixed wireless broadband solutions in the Chicago area, has selected a
DragonWave solution to roll out higher-bandwidth services to business customers. Business Only
Broadband is deploying DragonWave technology to increase the speeds of its primary, secondary and
disaster-recovery connectivity services in Chicago to more than 300 Megabits per second (Mbps)-and to
introduce those services in additional markets.

"We are near completion of our multi-million-dollar upgrade in Chicago, and we will be counting on
DragonWave to help us expand into New York, as well," said Richard S. Kingston, chief executive
officer of Business Only Broadband. "Our corporate customers seek to protect network operations
against failure and diversify networks that have been solely reliant on traditional, wire line local
exchange carriers. Consequently, we conducted an extensive search for a quality wireless partner
providing very high levels of scalability, reliability and security, and we found everything we were
looking for in DragonWave alone."

Added Chris Craven, chief operating officer of Business Only Broadband: "As clients look to Metro
Ethernet, MPLS (Multi Protocol Label Switching) and load-balancing solutions, Business Only Broadband
and DragonWave will team up to provide the best alternative to have secure, diverse data delivery."

Business Only Broadband is Chicago's largest wireless broadband provider, with a network of 29
transmission sites configured in self-healing ring architecture. The network is engineered
specifically to meet the data-continuity needs of today's business environment, such as redundant data
centers, interconnection with multiple Tier 1 transit providers, no common point of failure with the
embedded Telco infrastructure, full duplex-committed information rate services and scalable bandwidth
on demand.

"We believe our solution provides Business Only Broadband with a future-proofed strategy for ongoing
growth in Chicago, New York and additional markets," said Alan Solheim, vice president of product
management at DragonWave. "The power, cost-effective flexibility and security of DragonWave are the
tools that Business Only Broadband needs to serve fast-growing customers with changing bandwidth
requirements and the need to protect mission-critical application traffic."

DragonWave's Horizon and AirPair products operate within both licensed and unlicensed radio
frequencies in the 11-to-38-GHz range, ensuring interference-free performance for customers' traffic.
