Tata Communications Selects Proxim Wireless as Supplier of Mesh and Point to Multipoint Unlicensed Broadband Wireless Equipment

San Jose, March 31, 2008 — Proxim Wireless Corporation (NASDAQ: PRXM), a leader in core-to-client solutions for broadband wireless networks, today announced that Tata Communications Ltd. has selected Proxim Wireless as its supplier of Mesh and Point-to- Multipoint broadband wireless equipment operating in unlicensed frequency bands.

Tata Communications Ltd., with revenues of $2 billion is part of the $29 billion Tata Group, which has a global presence in more than 200 countries. Tata Communications has built one of the largest Global Tier-1 IP networks in the world.

The service planning team at Tata Communications evaluated a wide selection of broadband wireless products and vendors. The team picked Proxim as its supplier for Mesh and Point to MultiPoint products due to the excellent coverage and manageability of Proxim Wireless equipment.

Tata Communications and Proxim Wireless have collaborated on a number of projects to date including the Manipal Academy of Higher Education, Taj Hotel properties and Mahindra Resorts. Proxim's Point to Multipoint, Mesh and Wi-Fi products were deployed in these projects to deliver video, voice and data over Wi-Fi to the edge of the network. Proxim's dual-radio architecture separates the mesh backbone traffic from the edge access traffic, increasing capacity compared to a single-radio mesh architecture. Proxim's equipment provides both indoor and outdoor wireless coverage, with seamless mobility, at all deployments.

"Tata Communications was looking for a solution where the features and functionality of the equipment were the key criteria for selection. We carefully evaluated a number of potential suppliers and selected Proxim," stated Mr. Shankar Prasad, President, Retail Business Unit at Tata Communications.

"India is a significant growth market for us. Tata Communications is India's largest Tier- 1 IP network provider and we are honoured to have been selected by them as a preferred supplier. Tata's partnership with Proxim will enable voice, video and data applications over a scalable wireless infrastructure" said Pankaj Manglik, President and CEO at Proxim Wireless.
