The primary condition of wireless network optimization is to confirm the distribution of signal strength, and the wireless network optimization can be divided into outdoor optimization and indoor optimization according to spatial region classification, and a drive test mode is adopted in most cases for wireless network optimization in an outdoor environment. For wireless network optimization in an indoor environment, generally, sweep frequency or drive test equipment is manually held, and an area with weak signals in the indoor environment and an indoor interference source are searched through a directional antenna on the equipment to be checked so as to meet indoor signal coverage requirements.
Because the workload of manual frequency sweeping is large, most of the prior methods adopt a passive mode for testing, namely after receiving that the coverage of a certain indoor signal fed back by a user is insufficient, arranging manual work to go to the site for testing through a handheld device, and finding a weak signal area or finding an interference source for further processing. The search of the interference source generally depends on the combination of manpower, sweep frequency equipment and directional antenna, and the gradual approximation is determined on site. Indoor weak coverage optimization relies on manual work and test equipment, and each floor is traversed. The manual floor sweeping test is time-consuming and labor-consuming, low in efficiency and high in cost.
In practical application, 80% -90% of communication services occur indoors, and the traditional network optimization means mainly depends on user complaints, KPI indexes and the like to indirectly judge and position the indoor coverage condition, so that the real condition of the indoor network signal intensity cannot be deeply known. Therefore, the indoor interference source and the network weak coverage are identified, and the problem of the determined coverage of the indoor wireless network signal strength distribution condition is solved in advance is particularly important.
In order to solve the problem of the prior art, embodiments of the present application provide a method, an apparatus, a device, and a storage medium for determining a wireless signal strength.
