    15. 15. Wireless Mesh Networks <ul><li>Mesh routers (MRs) manage routing automatically based on ad hoc network technologies </li></ul><ul><li>Devices are flexible and self-configuring </li></ul><ul><li>All or a subset of MRs act as access points (Wi-Fi hot spot) </li></ul><ul><li>Some devices are the gateways to the Internet </li></ul><ul><li>Backhauling: WiFI, Hiperlan, WiMax, BPLC ... (maybe LTE MESH in the future) </li></ul>Internet mesh gateway mesh router mesh client Access Link Backhaul Gateway Link
