Abstract
A system includes a wireless switch and a plurality of wireless nodes. A mobile device connects to the wireless switch by communicating a packet to the wireless switch via two or more of the plurality of wireless nodes.
Claims11
A system, comprising:
- a wireless switch;
- and
- a plurality of wireless nodes,
- herein a mobile device connects to the wireless switch by:
- transmitting a data packet to the wireless switch via a primary associated wireless node;
- receiving an indication from the primary associated wireless node as to whether the data packet was successfully received;
- and
- transmitting the same data packet to the wireless switch via at least one other associated wireless node, and
- wherein the wireless nodes communicate with one another to determine the achieved level of redundancy of the same packet in order that only one access point sends on a single instance of the data packet to the wireless switch, and the at least one other associated wireless node discards the redundant packet, and
- wherein the wireless switch transmits the single instance of the packet on to a communication network.

A method, comprising:
- associating a mobile device with at least two wireless nodes;
- transmitting, by the mobile device, a data packet to a first wireless node of the at least two wireless nodes;
- receiving an indication from the first wireless node as to whether the data packet was successfully received;
- transmitting, by the mobile device, the same data packet to a second wireless node of the at least two wireless nodes;
- communicating between the wireless nodes to determine the achieved level of redundancy of the same packet in order that only one access point sends on a single instance of the data packet to the wireless switch;
- discarding the redundant packet by the other wireless node;
- and
- transmitting the packet on to a communication network by the one access point.
