Using picocells to build high-throughput 802.11 networks
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....
