Megafon Chooses Proxim for One of the Largest WiMAX-Capable Networks in Russia

Population of 32 Million Gain Affordable Broadband Access to Internet

San Jose, April 15, 2008 — Proxim Wireless Corporation (NASDAQ: PRXM), a leader in core-to-client solutions for broadband wireless networks, today announced that it has provided Tsunami™ MP.11 5054 radios for a wireless network in Russia to MSS Povolzhie, an Internet service provider and subsidiary of Megafon. This network will enable broadband Internet access for a population of over 32 million residents as well as businesses in a 2,500 square kilometer region. The contract was won in conjunction with RK Telecom and Geyser, Proxim's partners in Russia.

Prior to the installation of the Proxim Wireless network, the branches of Sberbank, Nafta and Lukoil and residents in the Samara region had no broadband access to the Internet. Megafon recognized that the businesses and residents needed a service that could offer broadband data and VoIP connectivity and evaluated the market for a flexible and scalable solution. Megafon required a wide frequency range — 5.150 to 6.080GHz — and channel sizes of 5, 10, and 20 MHz in a single product for deployment flexibility. Megafon's specification also demanded IEEE 802.16 WiMAX Quality of Service (QoS) for the wireless metropolitan access network.

"The residents and businesses in the region are really pleased to finally have broadband Internet access. Following the success of this project, we are now planning to extend Internet access to all regions of Povolzhie, starting with deployments in the larger cities," said Michael Borodko, Head of Information Technology Department, OJSC MSS Povolzhie. "We have been extremely pleased with the rapid installation and the reliable performance of the wireless network. It is robust and scalable as well as being flexible and therefore able to accommodate our specific requirements."

RK Telecom and Geyser specified the wireless network: "Proxim wireless equipment allowed us to deploy a network enabling high performance long range broadband access services to a large number of customers for the right price," said Mr. Druzhkov Nikolay, Commercial Director at RK Telecom.

"This installation demonstrates the flexibility, scalability and reliability of our Tsunami product line. Russia is an important growth area for Proxim offering significant opportunities, and it is good to know that we have the right products to meet the specialized requirements of that market," Lionel Chmilewsky, Executive VP Worldwide Sales at Proxim Wireless.
