Embodiment Construction
[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings.
[0043] see figure 1 , figure 1 It is a flow chart S100 of the positioning algorithm based on 2.5G wireless network signal profit and loss of the present invention; the flow chart S100 includes steps S101 to S105;
[0044] In step S101, the antenna gain and loss of the signal transmission between the mobile terminal and the base station in the 2.5G wireless network are obtained; a high-gain directional antenna must be used in the 2.5G wireless network, and the narrower the main lobe width of the antenna, the higher the gain. At a specific power, the higher the gain, the greater the radiation range;
[0045] According to an embodiment of the present application, in the signal transmissi...
