Abstract— In telecommunication networks, especially wireless, it is common for computers (machines) in residential scenarios and hotspots to see multiple access points (APs). These APs often provide wireless broadband but are connected to the Internet via independent, relatively slow links. With current wireless norms, one station is capable of connecting to only one AP. So, wireless clients must compete over throughput with all stations in the same SSID. Each client will be, therefore, left with a small portion of the bandwidth that fluctuates relatively to potential stations activity. However, in the ideal case, a client could benefit simultaneously from connections to all available access points and get the sum of their available backhaul bandwidth. Such perspective launched several proposals aiming to aggregate AP backhaul bandwidth, multiply the overall throughput and improve resources management. These propositions are basically founded on two different concepts namely the client based and the AP based backhaul aggregation.
Index Terms— Aggregating AP, backhaul bandwidth, co-channel signaling, fair backhaul aggregation, sharing AP.
