Proxim's Ultra-Secure WiMAX Product Family is Industry's First to Receive FIPS 140-2 Level 2 Certification

Secure Mobile Video Surveillance, Data Connectivity, and VoIP for Governments, Utilities, Financial Services, Healthcare and Enterprises

Silicon Valley, CA (Vocus) March 5, 2009

Proxim Wireless Corporation (http://proxim. com/) (NASDAQ: PRXM), a leading provider of end-to-end broadband wireless systems that deliver the quadruple play, today announced that the Proxim Tsunami™ MP.11 HS (http://proxim. com/products/mp11_hs/) (High Security) line of base stations and subscriber units are the first point-to-multipoint wireless broadband products to be certified with Federal Information Processing Standards Publications (FIPS) 140-2 Level 2 validation, meeting security requirements for cryptographic modules. FIPS 140-2 Level 2 (http://en. wikipedia. org/wiki/FIPS_140-2) validation is a requirement for any cryptographic product which will be used in a U. S. government agency network, and meets the stringent security requirements of healthcare organizations, financial institutions and other highly secure enterprises.

“FIPS certification is paramount in our ability to sell the concept of using a broadband wireless network for Homeland Security applications,” said Tim Stewart, President of Netunwired, a provider of VoIP and wireless backhaul for broadband networks, and Senior Wireless Engineer for Avrio Group. “We find that for most city deployments, AES encryption on the radio interface has become commonplace in RFPs. However, for Federal deployments, the encryption must also be FIPS compliant to ensure that the highest security standards are maintained and sensitive data is not intercepted and deciphered.”

The Tsunami MP.11 HS product family provides governments, utilities, financial services, healthcare and ultra-secure enterprises with the industry’s first FIPS 140-2 level 2 compliant point-to-multipoint products in the 5.1-5.95 GHz, 4.9 GHz, 2.4 GHz, and 1.8 GHz frequency bands. Combining FIPS 140-2 level 2 compliance, advanced AES-256 encryption, and secure management to meet strict U. S. Federal Government standards as well as HIPAA (http://en. wikipedia. org/wiki/HIPAA) requirements, the MP.11 HS is Proxim’s ultra-secure broadband wireless solution for wireless video, data connectivity, VoIP and mobility. Whereas competitors’ approaches to high security wireless broadband require multiple products to be bolted together to achieve FIPS 140-2 compliance and AES-256 encryption, Proxim is a truly integrated solution that offers these security features – as well as secure management – in one box.

“We have over 10 years experience in assisting our clients through the process of achieving FIPS 140-2 certification, and we have confirmed that Proxim’s Tsunami MP.11 HS line of products are the first point-to-multipoint wireless products on the market to achieve this critical certification,” said Matthew Appler, CEO, Corsec Security, Inc. “This FIPS 140-2 validation of Proxim’s MP.11 HS products provides the high degree of security, assurance and dependability mandated for all government deployments – while also exceeding the requirements of even the most secure enterprises.”

By combining this high security with the high throughput required for bandwidth-intensive video, the Tsunami MP.11 HS solution is appropriate for use in security video surveillance in ports, cities, and along transportation infrastructures. In addition, the products are designed to handle the specific challenges of delivering bandwidth-intensive video to mobile law enforcement vehicles, enabling mobile security patrol units to view wireless video surveillance in real-time. The Tsunami MP.11 HS enables this via new support of the governmental 1.8 GHz frequency while also enabling mobile roaming with seamless handoffs at speeds of up to 120 mph (200 km/hour).

Though the Tsunami MP.11 HS supports the 1.8 GHz governmental frequency and meets or exceeds FIPS standards with the performance needed for real-time wireless video, the Tsunami MP.11 HS is effective for much more than just governments. The Tsunami MP.11 HS is also ideal for any and all non-governmental organizations in need of highly-secure broadband wireless solutions, and the new product family is available immediately for all customers globally. This means that all enterprises and organizations concerned with deploying ultra-secure point-to-multipoint wireless systems now have access to Proxim’s MP.11 HS solution.

The FIPS 140-2 standard is a joint effort by the National Institute of Standards and Technology (NIST) in the United States, and the Communications Security Establishment Canada (CSEC). Already mandated by law in the U. S. and very strictly enforced in Canada, FIPS 140-2 is also currently being reviewed by ISO to become an international standard. The standard provides stringent third-party assurance of security claims on any product containing cryptography that may be purchased by a government agency.

Proxim Makes it Easy with GSA Inclusion

The General Services Administration (GSA) Schedules program establishes long-term, government-wide contracts with commercial firms to provide access to commercial products and services. This contract can be utilized by any federal agency and in many cases by state and local governments as well. The Tsunami MP.11HS product is being added to the GSA Schedule and can be purchased through authorized GSA resellers by federal, state and local governments directly without the need to go through a lengthy RFP process which would otherwise be required. Additionally, agencies can easily search for and purchase other Proxim products online using the GSA Advantage website by visiting: http://www. gsaadvantage. gov/ (http://www. gsaadvantage. gov/).
