摘要： Systems and methods for adaptive frequency hopping for reducing or avoiding electromagnetic interference between two radios operating in the same radio frequency (RF) band are provided. In one aspect, a host device, which includes first and second wireless radios and a hardware processor, can use adaptive frequency hopping among a plurality of RF channels to reduce interference. The device can control the first wireless radio to establish a first wireless connection with a terminal device via a first subset of channels, determine a set of performance statistics for the channels, and replace at least one of the first subset of the channels with a new channel within the plurality of channels based on the statistics. For example, a channel can be replaced if a packet error rate (PER) exceeds a threshold.
