Channel partitioning for wireless local area networks
First Claim
Patent Images
1. A system for improving performance in wireless communications to an IP network, comprising:
- a) at least one access point that is equipped with at least one transceiver configured to simultaneously transmit and receive on multiple channels;
b) wherein said access point is configured to pool users onto said channels based on channel conditions and to allocate as many users from a respective set of users as possible to each channel;
c) wherein said access point is configured to assign users to channels based on a heuristic algorithm; and
d) wherein;
a) the access point is configured to separate users into a number of classes of users having respective levels of throughput;
b) when the users can be admitted, the access point is configured to allocate said users to said channels as follows;
i) on the each channel, the access point allocates the users from a respective class as possible.1) when the number of users in said respective class is less than the channel capacity for that class, there is no spill-over traffic of calls, and all said users in said respective class are allocated to that channel;
2) when the number of users in a class is more than the channel capacity for that class, there is spill-over traffic of calls, which calls are further assigned by the access point going through said classes in a step-wise manner starting at a higher throughput class so as to pair spill-over traffic having a higher throughput with that having a lower throughput.

Abstract
The present application discloses, inter alia, a system for improving the aggregate throughput of a wireless local area network which includes: at least one access point that is equipped with at least one transceiver configured to simultaneously transmit and receive at multiple frequencies using multiple channels; and the access point being configured to acquire channel conditions of users and to pool sets of users on the channels based on the channel conditions.
