Abstract
A method for channel quality estimation is executable by a network device. The network device divides channels into a plurality of groups according to a number of channels available in a competing network environment in which the first network device is located, and selects a representative channel from each of the plurality of groups which is central to the frequencies of each available competing channel. The selected representative channels are each tested and each of the channel quality estimations is taken as channel quality estimation of all channels of a group, to save time in estimating and increase efficiency.
Claims10
A network device wireless communicating with at least one other network device through a plurality of channels, wherein the network device and the at least one other network device are inside a coverage area of a wireless network, the network device comprising:
- at least one processor;
- a non-transitory storage system coupled to the at least one processor and configured to store one or more programs configured to be executed by the at least one processor, the one or more programs including instructions for:
- dividing the plurality of channels into a plurality of groups according to a channel profile of the wireless network;
- selecting a representative channel from each of the plurality of groups, to obtain a plurality of representative channels;
- sending packets to the other network device through the plurality of representative channels;
- receiving channel quality estimations from the other network device;
- and
- updating a table of channel quality estimations according to the channel quality estimations, wherein each channel quality estimation represents channel quality of all channels of a group.
