A high-density wi-fi coverage method

Abstract

A high-density WI-FI coverage method relates to the field of communication technology, including a WI-FI module, the WI-FI module includes a microprocessor and a WI-FI module, and the WI-FI module also includes An ad hoc network wireless communication module is provided. After the WI‑FI terminal is connected to the WI‑FI module, the WI‑FI module will feed back the channel bandwidth to the microprocessor in real time. If the channel bandwidth is smooth, the microprocessor will let the WI‑FI terminal connect to the network directly through the WI‑FI module. If the channel bandwidth is congested, the microprocessor transfers the WI‑FI terminal data to the ad hoc network wireless communication module; the networking wireless communication module automatically sorts the WI‑FI terminals, and makes the WI‑FI terminals orderly according to the priority value for network access. Compared with the existing technology, this method is suitable for WI-FI high-density scenarios. When a large number of WI-FI terminals need to be connected to the network, the WI-FI terminals are managed through the wireless communication module of the ad hoc network, so that the WI-FI ‑FI terminals are connected in an orderly manner to keep the WI‑FI channel unobstructed, allowing WI‑FI terminals to access the network quickly and in batches.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a channel allocation method in a high-density WI-FI environment. Background technique [0002] In the field of wireless communication, with the development of wireless communication and the popularization of WIFI devices, there are scenarios where hundreds or thousands of WIFI devices need to be deployed. However, whether it is the 2.4G frequency band or the 5.8G frequency band, the number of available channels is often limited. In a high-density scene with thousands of WIFIs (the so-called high-density scene means that there are a large number of WIFI devices in a limited area ), each channel needs to carry a large number of devices, and WIFI devices on the same channel often interfere with each other in the process of sending and receiving messages at the same time, which will lead to a sharp drop in WiFi transmission speed and greatly reduce network performance.

AI Technical Summary

Problems solved by technology

This kind of method has high algorithm complexity, high CPU usage rate during operation, and takes a long time for each channel allocation. The performance is acceptable for a simple network topology and a small number of WIFI devices, but for network topology with relatively Unsatisfactory performance with multiple WIFI devices

Although another algorithm based on the number of neighbors sorts avoids a large number of complicated RSSI value comparisons and improves the speed of channel allocation to a certain extent, its performance still needs to be further improved for high-density scenarios.
