In one embodiment, the multiple connection quality evaluation parameters include at least one of a frequency band quality evaluation parameter and a channel quality evaluation parameter. The number or types of frequency band quality evaluation parameters and channel quality evaluation parameters can be one or more.

In one embodiment, the frequency band quality evaluation parameter may reflect the frequency band quality of multiple candidate communication frequency bands. Among them, each frequency band covers a frequency range. For example, assuming that the candidate communication frequency band includes 4 frequency bands Band(1)~Band(4), the frequency band quality evaluation parameters can reflect the respective frequency band quality of these 4 frequency bands Band(1)~Band(4).

In an embodiment, the frequency band quality of the frequency band Band(k) can be represented by the power when the wireless signal sharing device 11 operates in the frequency band Band(k).

For example, assuming that the channels 101(1) to 101(n) belong to the frequency band Band(k), the channel quality evaluation parameters can reflect the individual channel quality of the channels 101(1) to 101(n) in the frequency band Band(k).

In one embodiment, the number of connected devices of channels 101(1) to 101(n) can be regarded as the first channel quality evaluation parameter. The first channel quality evaluation parameter can reflect the total number of wireless signal sharing devices operating on the target communication channel 101(i) in the current environment. If the number of connected devices of the target communication channel 101(i) is larger, it means that there are more wireless signal sharing devices currently operating on the target communication channel 101(i), which may cause the bandwidth resources of the target communication channel 101(i) to be occupied More.

The second channel quality evaluation parameter can reflect the total number of wireless communication devices connected by the wireless signal sharing device 11 via the target communication channel 101(i) in the current environment. If the channel utilization rate of the target communication channel 101(i) is higher, it means that the wireless signal sharing device 11 is currently connected to more wireless communication devices via the target communication channel 101(i), so it may also cause the target communication channel 101(i) to fail. Bandwidth resources are occupied more.

In one embodiment, the wireless signal quality of the channels 101(1) to 101(n) can be regarded as the third channel quality evaluation parameter.

For example, the wireless signal quality of the target communication channel 101(i) can be expressed by Received Signal Strength Indication (RSSI). If the measured RSSI value of the target communication channel 101(i) is larger, it means that the wireless signal quality of the target communication channel 101(i) is better.

After the wireless communication device 12 and the wireless signal sharing device 11 establish a connection based on a certain channel, the processor 22 can obtain the third channel quality evaluation parameter corresponding to this channel.

These initially screened communication channels may have the least number of connected devices (or relatively few) and/or the lowest (or relatively low) channel utilization. Then, the processor 22 can sequentially establish a connection with the wireless signal sharing device 11 based on the communication channels that have been preliminarily screened out, and obtain the corresponding third channel quality evaluation parameters. Then, the processor 22 can determine the channel with the best (or relatively better) wireless signal quality as the target communication channel from the communication channels that have been preliminarily screened according to the third channel quality evaluation parameter.

Thereafter, the wireless signal sharing device 11 and the wireless communication device 12 can synchronize and perform wireless communication with each other based on the target communication channel (ie, the target communication channel 101(i)).
