WiFiRe: Rural Area Broadband Access Using the WiFi PHY and a Multisector TDD MAC
The needs of Indian rural telecom, and the economics of currently available broadband access technologies, motivate a new system for rural broadband access, which the authors call WiFiRe (WiFi Rural Extension). The system leverages the widely available, and highly cost-reduced, WiFi chipsets. They, however, retain only the PHY from these chipsets and propose a single-channel, multisector, TDD MAC using directional antennas. The proposed WiFiRe MAC is similar to the WiMAX MAC in several respects. In this paper, they motivate their approach, describe the system architecture and the MAC, analyze the spatial reuse, and then, using a simple scheduler, provide an assessment of the voice and data capacity of a WiFiRe system.
