Proxim Wireless Announces Solutions for Community Access Networks; Dual-Radio, Multi-Frequency Outdoor Wi-Fi Mesh Access Points Complement WiMAX Products for Scalable Networks; Equipment Grant Program Speeds Adoption for Deserving Communities

Business Wire, April 27, 2006

SAN JOSE, Calif. & LAS VEGAS -- Proxim Wireless Corporation, a global provider of broadband wireless equipment and wholly-owned subsidiary of Terabeam, Inc. (NASDAQ:TRBM), today introduced two major initiatives aimed at advancing the deployment of broadband wireless networks for municipalities worldwide. The company announced a family of dual-radio, multi-frequency, ruggedized outdoor Wi-Fi mesh products, leveraging its heritage of excellence in enterprise-class Wi-Fi as well as outdoor broadband wireless networking, including the globally renowned ORiNOCO(R) wireless LAN and Tsunami(R) point-to-multipoint and WiMAX product lines. The ORiNOCO AP-4000MR-LR provides a powerful cornerstone for large metropolitan Wi-Fi deployments, while the AP-4900MR-LR enables broadband wireless communications unique to public safety by operating at the 4.9 GHz frequency band. The company also announced a selective equipment grant program to speed the benefits of these products to deserving communities.

"As a leading vendor of broadband wireless technologies including Wi-Fi and WiMAX, we have developed a set of complementary solutions designed to enable truly viable and scalable Community Access Networks," said Robert Fitzgerald, Chief Executive Officer, Proxim Wireless. "A robust multi-use network requires a combination of technologies. Our ORiNOCO outdoor mesh products, in conjunction with our Tsunami point-to-multipoint and point-to-point systems, provide the performance, reliability and cost profile to ensure that end users receive services of the highest quality, and network operators can grow the network as demand increases. It is our opinion that Proxim's end-to-end offering provides the best solution available today for municipalities and service providers."

"Providing Wi-Fi coverage over an entire metropolitan area - well beyond hot spots - is now a truly global trend," said Craig J. Mathias, a Principal with the wireless and mobile advisory firm Farpoint Group (Ashland, MA). "Proxim's entry into this market adds both credibility and a very strong player to the metro Wi-Fi opportunity, which is absolutely huge."

Invitation to US Communities - Wireless Equipment Grant Program

In addition to announcing its new outdoor mesh products, Proxim Wireless is also announcing a special "Equipment Grant Program" for selected municipalities. To qualify for consideration, municipalities must currently be in the planning stages of deploying a Community Access Network. Under the Program, Proxim plans to award to two cities, each of which meets certain qualifications, a quantity of its new outdoor mesh products without cost for use in Municipal Wi-Fi or Public Safety applications.

More About ORiNOCO(R) Outdoor Mesh Products

The ORiNOCO(R) AP-4000MR-LR series of ruggedized, dual-radio wireless mesh access points is based on the world-renowned ORiNOCO enterprise-class Wi-Fi platform. One radio provides Wi-Fi (802.11b/g) end user access, while the other radio in the same compact product enclosure provides mesh backhaul using a pre-802.11s protocol. By using two radios operating at different frequencies, system capacity is doubled and interference is significantly reduced. Furthermore, the mesh protocol secures links using AES encryption, supports both fixed mesh (all APs mounted statically) or mobile mesh (in-vehicle versions of the mesh AP interacting with APs mounted statically) configurations, and VLAN information is kept intact over mesh links to enable virtual networking. Another advantage is draft 802.11e and draft 802.1p quality of service (QoS) enabling converged but differentiated carriage of voice, video and data traffic.

The ORiNOCO outdoor mesh access point is available in three variants. All of them are based on a common platform of two radios, with one radio providing 802.11 b/g Wi-Fi end user access, and the second radio providing mesh backhaul at:

--5.8 GHz for the U.S. municipal market as well as other markets where this is an available band (AP-4000MR-LR)

--4.9 GHz (public safety band designated by the FCC) specifically for public safety organizations (AP-4900MR-LR)

--5.4-5.7 GHz frequency band for European countries (AP-4000MR).

End-to-End Solutions for Enterprise-Quality, Cost-Effective Wireless Mesh

Proxim Wireless has the depth of experience and breadth of portfolio to offer end-to-end (from very high capacity backhaul to end user access) wireless solutions. A complete, advanced municipal network will need to encompass backhaul, middle mile, edge access, client devices, and network optimization. Proxim Wireless provides the entire solution:

--ORiNOCO AP-4000MR-LR for simultaneous 802.11a and 802.11b/g Wi-Fi edge access with mesh networking

--ORiNOCO AP-4900MR-LR for simultaneous 4.9 GHz public safety and 802.11b/g Wi-Fi edge access with mesh networking

--Tsunami MP.11, providing capabilities of WiMAX in license-free frequency bands worldwide, for last mile connectivity to a wireless mesh network
