Problems solved by technology

[0007] However, there are still many problems in the application of this technology. For example, when using a wireless local area network with a frequency of 2.4GHz, fatal failures may occur in other electronic products such as microwave ovens that are close to the frequency range of 2.4GHz due to the radio wave interference of the wireless local area network.
[0008] Moreover, the wireless local area network can allocate 13 communication channels, but strong interference occurs between these channels, so it is impossible to listen to more than 3 channels at the same time. In order to solve the above problems more effectively, it is necessary to introduce new related technologies
