Dragonwave Expands Frequency Coverage to Support Carrier Ethernet Services in More Global Markets

Support for 6 to 8 GHz Frequencies Valuable for Wireless Backhaul in North American, European and
Equatorial Deployments

OTTAWA, CANADA--(Marketwire - March 31, 2008) - DragonWave Inc. (AIM:DWI)(TSX:DWI), a leading global
supplier of next-generation wireless networks, today announced that it has expanded its coverage to
include the 6 to 8 GHz range of licensed radio frequencies. This enhanced frequency coverage on the
Horizon Compact product dramatically improves DragonWave's relevance as a provider of wireless
backhaul solutions for a variety of geographic markets around the world.

"Mobile and fixed wireless services are reaching more and more areas of the world, and, as they do,
backhaul is emerging as a common source of bottlenecks," said Michael Kennedy, president, with Network
Strategy Partners. "Wireless Carrier Ethernet provides a simple and cost efficient solution to this
problem, and having frequency coverage from 6 to 38 GHz enables applications in a wide variety of
environments."

Carriers seek 6 to 8 GHz frequency coverage for backhauling wireless traffic in remote, rural areas or
in high rain regions such as equatorial zones because it enables interference-free transport over
longer distances. In North America the upcoming availability of 700 MHz spectrum for access coupled
with a Carrier Ethernet solution operating at 6 to 8 GHz frequencies delivers a compelling solution
for bridging the urban-rural digital divide.

"DragonWave's support of the 6 to 8 GHz range enhances our ability to offer cost-effective and high-
performance network solutions on a global basis," said Robert Dew, director, network engineering with
NextWave Broadband Inc., which partners with DragonWave to supply service providers worldwide with
fully integrated, end-to-end, mobile broadband and transport network solutions. "One of the main
reasons that this partnership is so successful is DragonWave's introduction of enhanced functionality
in close sync with the evolving needs of our customers."

The Horizon Compact-delivering 800 Mbps full duplex capacity-operates in licensed radio frequencies up
to 38 GHz. DragonWave is the only equipment provider supporting such a wide frequency band in an all-
outdoor configuration. DragonWave's Horizon Compact keeps a carrier's capital and operational
expenditures in check by integrating all of the necessary functionality of traditional wireless indoor
and outdoor units in a single, outdoor, 9-inch-square, native Gigabit Ethernet microwave transmission
system. Installation and other operational burdens are reduced, as the Horizon Compact demands no
footprint in indoor base-station cabinets and uses standard CAT5E cabling with Power over Ethernet.
Furthermore, the Horizon Compact enables "virtual integration" into DragonWave partners' equipment, as
it can be powered and managed directly via the base-station equipment without requiring the
development of new interfaces.

"Our move to support 6 to 8 GHz frequencies is another sign that Carrier Ethernet has moved beyond an
initial adoption stage," said Alan Solheim, vice president of product management at DragonWave.
"Carriers now need solutions tailored for deployments other than the high-density metropolitan areas
where services were first introduced. With many of our customers seeking to upgrade legacy equipment
to IP (Internet Protocol) in more areas of their service footprint, this made the time right to expand
our frequency coverage. And we will continue to do so, as necessitated by arising market
requirements."

The DragonWave solution offers a full suite of network-management options and supports 50 ms switching
and 99.999 percent service availability over point-to-point, ring and mesh network topologies. Horizon
Compact delivers industry-leading IP functionality including jumbo frames, 802.1 prioritization, flow
control and virtual local area network (VLAN) management-as well as fast modulation shifting,
integrated radio frequency (RF) loopback and Automatic Transmit Power Control.
