Service Provider Cuts Capital and Operational Expenses for Offering WiMAX and GSM Services to
Businesses and Consumers

OTTAWA, ONTARIO--(Marketwire - May 5, 2008) - DragonWave Inc. ("DragonWave") (TSX:DWI)(AIM:DWI) a
leading global supplier of next-generation wireless networks, today announced that M3 Wireless is cost-
effectively converging its WiMAX data and GSM voice services for business and residential customers on
a DragonWave IP backhaul solution. DragonWave's AirPair product interlinks 27 sites across M3's meshed
Ethernet network spanning Bermuda.

"DragonWave gives us a robust transport solution that stands to meet our needs now and into the
future," said Lloyd Fray, chief executive officer (CEO) of M3 Wireless. "We selected the AirPair
product initially because of its unique Ethernet functionality, such as rapid-link shutdown and
Quality of Service support. As we deployed DragonWave across more and more of our network, we were
able to realize the terrific cost savings of converging data and voice on the same IP, pseudowire
infrastructure."

M3 is the only purely Bermuda-operated provider of cellular data and voice services. It offers
broadband connectivity to business and consumer customers, and in 2006 the service provider extended
its innovative WiMAX offerings to island-wide deployment. As service uptake intensified, M3 sought a
more scalable backhaul solution that would provide interference-free, licensed-band wireless
performance. In standardizing on the DragonWave solution, M3 was able to backhaul not only the data
services but also its GSM voice services on the wireless, 100 Megabits per second (Mbps)
infrastructure. AirPair has dramatically reduced M3's capital and operational expenses for
transporting mixed services by merging the backhaul data and voice traffic on a single IP-based
infrastructure.

"With demand intensifying for personal broadband services such as WiMAX, wireless backhaul is a
growing concern for service providers," said Peter Allen, president and CEO of DragonWave. "Our
AirPair product has a strong track record of providing cost-effective, dependable backhaul in markets
worldwide, and we look forward to working with M3 Wireless as it continues to expand its offerings in
Bermuda."

DragonWave's Horizon and AirPair products operate within both licensed and unlicensed radio
frequencies in the 6-to-38-GHz range, ensuring interference-free performance for customers' traffic.
The DragonWave solution provides scalable, ultra-low latency, wire-speed native Ethernet connectivity
up to 800 Mbps full duplex. The system is extremely easy to deploy and manage, with a full suite of
network management options. AirPair has indoor and outdoor deployment options, and is a highly
reliable platform enabling 99.999% service availability.
