Qinghai Provincial Center for Disease Control and Prevention uses Huimingjie self networking equipment (1 set of basic node equipment, 2 sets of portable node equipment, 4 sets of individual node equipment, 12 sets of self networking digital walkie talkies) to realize wireless ad hoc network, which has played an important role in the response to public health emergencies such as health emergency communication, disaster relief, disease prevention, infectious disease and epidemic situation disposal in Qinghai Province. In wireless ad hoc networks, lines between cell nodes are usually composed of multiple node devices. Although the wireless transmission distance is limited, the purpose of mutual communication between two node units that are far away can be achieved by adding intermediate node equipment. The network can be automatically formed without the preset base station as the basis, which is highly destructive. Based on the wireless technology of Mesh ad hoc network, it shows a new idea of wireless network access.
