    66Taking on the unique challenge, the team at Motorola Applied Research & Technology Center, Bangalore, headed by Dr. V. Thyagarajan and under technical leadership of Atanu Guchhait, is developing low-cost and medium-range networking technologies (1-1.5Km cell radii) based on the popular IEEE 802.11 a/b/g standards. The aim is to increase the range of the popular standard 10-fold with minimal modifications to the 802.11 standard. This will enable the team to use off-the-shelf components, keeping the equipment prices low. At the same time, increasing the range will allow them to support a large area (main buildings in a village, like school, postal office, administration buildings) in one wireless hop connected to one DSL connection. This ensures reasonable data rates to 20-30 terminals at 256-512 kbps, providing an adequate user experience.

    8 To demonstrate their new technologies, the team is using [wiki:HardwareUsersGuides WARP hardware] and the [wiki:OFDMReferenceDesign WARP reference designs] which are loosely based on 802.11 standards.  The key research focus is on adapting the MAC protocol to handle longer distances and improving PHY performance to work at larger distances. The team (see photo) consists of a cross-disciplinary team which has expertise in hardware, networking protocols, PHY layer designs and radio propagation.
