The invention provides a wireless terminal STA positioning method and device which are applied to wireless controller ACs in the wireless local area network (WLAN), wherein the ACs are used for managing a plurality of wireless access points (APs). The wireless terminal STA positioning method includes the following steps of sending a collection control instruction to the relevant APs of STAs to be positioned, wherein the collection control instruction is used for indicating the relevant APs to send a beacon measurement request (BMRQ) to the STAs to be positioned; acquiring signal intensity parameters between N APs and the STAs to be positioned through downlink interfaces of the ACs, wherein the N is a natural number; and calculating positions of the STAs to be positioned according to the signal intensity parameters between the N APs and the STAs to be positioned as well as positions of the N APs when N is larger than or equal to three. Compared with wireless terminal STA positioning methods and devices in prior art, the wireless terminal STA positioning method and device have the advantages of being low in cost, good in compatibility, and capable of substantially reducing networking deploy costs of users.

The invention provides an indoor covering device and a multi-system covering system. The device comprises a baseband expansion module, and a plurality of multi-system distributed modules which are arranged in the covering area; the baseband expansion module in a downlink is used for receiving a downlink baseband signal output by a baseband data processing module of a small base station, performing bit width conversion for the downlink baseband signal and distributing to each multi-system distributed module; the multi-system distributed modules are used for receiving the downlink baseband signal from the baseband expansion module, performing bit width module for the downlink baseband signal, and performing radio frequency processing to obtain a downlink radio frequency signal for achieving signal covering. According to the device, the baseband expansion module is used for performing bit width conversion for the downlink baseband signal and distributing the downlink baseband signal to each multi-system distributed module in the covering area, then the multi-system distributed module is used for converting the downlink baseband signal into the radio frequency signal for achieving network covering, and therefore, the network coverage range can be expanded, and medium and large size scenes can be covered with the signal well.

Embodiments of the invention provide a method and a device for transmitting network data, and belong to the technical field of communication. According to the method, safety equipment comprises a first CPU, a second CPU and a memory; a first gateway subsystem runs on the first CPU, and a second gateway subsystem runs on the second CPU, wherein the first CPU uses the first gateway subsystem to create a plurality of first virtual devices, the second CPU uses the second gateway subsystem to create a plurality of second virtual devices corresponding to the first virtual devices respectively, and amemory area shared by the first virtual devices and the second virtual devices corresponding to the first virtual devices is arranged in the memory; each first virtual device receives a service message sent by a network device in the first network, extracts effective data in the service message, and stores the effective data in a data writing area of the first virtual device in the memory area; and each second virtual device reads the effective data from the data writing area of the corresponding first virtual device and forwards the effective data. By the adoption of the method and the device, the network layout cost can be reduced.
