High and low frequency combined ad hoc network method and device

The invention provides a high and low frequency combined ad hoc network method and equipment. The method is applied to a source node, and comprises the following steps: after a low-frequency measurement and control networking sub-device of the source node receives a communication request sent by a source node control system, establishing a routing link between the source node and a destination node; sending routing planning information to high-frequency-band directional transmission sub-equipment of each node in a routing link, so that the high-frequency-band directional transmission sub-equipment of each node in the routing link generates beam control information; the source node low-frequency band measurement and control networking sub-equipment receives beam control information sent by the source node high-frequency band directional transmission sub-equipment, and beam forming is controlled according to the beam control information; and sending communication information to the next node in the routing link
