Abstract: Embodiments of the present invention relate to the field of network communications and provide a backhaul device and a backhaul device control method. The backhaul device includes: an access-side baseband transmit module, an access-side baseband receive module, a backhaul-side baseband transmit module, a backhaul-side baseband receive module, a radio frequency channel, a first switch module, a second switch module, an access antenna, and a backhaul antenna. Therefore, problems of low resource utilization of a radio frequency channel and high system development costs in the prior art are resolved, and the radio frequency channel can be shared, so as to improve resource utilization. In addition, considering that the radio frequency channel includes multiple components, the radio frequency channel is shared, which reduces a quantity of components required for a system and development costs of the system.
