Abstract
A system and method is provided for improving signal quality in communications among fully wireless systems including a host device in wireless communication with a primary accessory which further wirelessly communicates with a secondary accessory. The host device generates information for use by the primary accessory in determining which channels have interference and should be avoided. The information may include an adaptive frequency hopping (AFH) channel map for communications between the host and the primary device, from which the primary device can infer which frequency bands have interference and generate a second AFH map for communications between the primary accessory and the secondary accessory accordingly. In other examples the information includes the second AFH map generated by the host, for example, based on an out-of-band scan. In further examples, the information includes an indication of channels used by recognized nearby access points.
