DRAGONWAVE ACHIEVES CERTIFICATION FROM

METRO ETHERNET FORUM

Horizon Compact is now fully MEF 9 and MEF 14 certified

for carrier-Ethernet service delivery over microwave

Ottawa, Canada,  Nov 18, 2009 - DragonWave Inc. (TSX: DWI; NASDAQ: DRWI) a leading global supplier of packet microwave radio systems for mobile and access networks, today announced that it has received Metro Ethernet Forum (MEF) certification for its Horizon Compact packet microwave radio solution. The MEF certification program provides service level benchmarks for manufacturers’ equipment and service provider performance in complex Ethernet-based networks. Horizon Compact is now MEF 9 and MEF 14 certified.

Iometrix, an independent testing lab and the official certification lab of the Metro Ethernet Forum, performed the testing of DragonWave’s Horizon Compact high-capacity packet microwave radio system.  MEF 9 and MEF 14 are complementary specifications that provide a comprehensive set of test cases to determine the readiness of Carrier Ethernet equipment to deliver standard Ethernet services and ensure interoperability in a multi-vendor environment.

“DragonWave’s Horizon Compact product successfully passed the very stringent compliance testing required for MEF 9 and MEF 14,” said Bob Mandeville, President of Iometrix. “MEF standards contribute to the accelerated worldwide adoption of Carrier Ethernet services”.

“As a member of the MEF, we feel strongly that certification of our Horizon Quantum is important for our customers who are making decisions about deploying packet-based networks and services,” said Alan Solheim.  “Independent certification provides the differentiation needed to build confidence in the interoperability of equipment in our customers Packet Microwave networks.”
