Using picocells to build high-throughput 802.11 networks
Jul 1, 2004
By Gregory Davi In a typical indoor 802.11 wireless network, a single access point can cover
2500 to 10,000 square feet. Picocells are substantially smaller RF coverage
areas and are used to provide high data throughput for dense wireless
terminals/appliances by minimizing the amount of bandwidth that is shared
among wireless users....
