Abstract
A data transmission method, where a host acquires parameter information of a wireless communication channel between a wireless microphone array and the host, that is, a signal-to-noise ratio or bandwidth. The host reduces sampling frequency of the wireless microphone array or decreases a quantity of data transmission paths between the wireless microphone array and the host when the acquired parameter information satisfies a first preset condition such that bandwidth occupied when the wireless microphone array transmits data is reduced.
