Case Studies - Wireless

A large equipment manufacturer in the United States was planning to build devices integrating ATM and mobility to provide high bandwidth access to wireless devices. Recognizing our expertise in the area, the customer commenced a Dedicated Facility with us.

We implemented a fully operational Wireless and ATM integrated network solution (25 Mbps shared bandwidth) for the customer that was one of the first of its kind. It involved licensing and extensive use of the Company's ATM routing/routing stacks and certain proprietary extensions to handle mobility. After the primary delivery in January 1999, we also provided support for field trials at the customer's end-user sites in the United States and Europe.

A major telecommunication equipment manufacturer in the United States had developed an IEEE 802.11 based product for wireless LAN access inside an office or corporate environment. However, this product did not have the requisite security features to be used widely in public places. The customer wanted to make a wireless LAN product by using PPP over Ethernet, which would provide secure connectivity for Wireless networks in public places such as airports, hotels and convention centers.

In order to demonstrate proof of concept, we initially developed a quick prototype, which was deployed successfully at a community in North America in mid-1999. Subsequently, we implemented the software for the full-featured 11 Mbps shared bandwidth product. Our primary responsibility was to develop the client component of the product, residing in laptops/desktops and access server functionalities including support for roaming. We were also involved in the licensing and porting of its PPP and RADIUS Client software products on the Server component.
