Access point range extension
View Patent ↗A technique for expanding the range of coverage for a wireless local area network (WLAN) involves locating a wireless access point (WAP) away from an interworking unit (IWU) at the edges of the WLAN and a (typically) wired network. The WAP, when located away from the IWU, can be referred to as an untethered access point (UAP) because it communicates with the IWU on a wireless channel. Stations on the WLAN will be capable of communicating with the WAP, whether or not it is a UAP, via a known or convenient wireless protocol, such as Wi-Fi, and may or may not be capable of communicating with one another via a direct station-to-station protocol.
1. A system comprising:
a network switch for coupling a first network segment to a second network segment, wherein the first network segment includes a wireless network;
an untethered access point (UAP), wherein the UAP functions as a wireless access point (WAP) for the wireless network;
a wireless distribution point (WDP) coupled to the network switch and wirelessly operationally connected to the UAP, wherein the WDP functions as a non-WAP station on the wireless network; and
an access point (AP) range extension engine:
wherein, in operation:
the UAP receives a message from a station on the wireless network having a destination that is not on the wireless network;
the WDP receives the message from the UAP;
the network switch allocates traffic, including the message, from the first network segment to the second network segment, and
the AP range extension engine performs network analysis to determine which of a plurality of stations on the wireless network can act as the UAP without a first station of the plurality of stations being required to act as a repeater for a second station of the plurality of stations.
