Is Jinjiang Star's Wi-Fi popular in China? Stay in a new city, even Wi-Fi shows the password, but you can connect without entering the password.

First, in view of what you said, it is obviously universal.

Secondly, the implementation method is introduced.

In public places and chain institutions, wireless management systems are generally deployed, such as Xinquan wireless management. There is a hierarchical relationship between headquarters and branches. Different levels have different management rights, and all network information will be stored in the headquarters server. In short, different hotels are just different LANs for them. If they allow you, you can access all the wireless networks under their names.

Usually, if they have a complete data analysis, some unencrypted information such as your location information and behavior has been recorded and will be kept for at least 6 months, and even some information will be pushed.

Finally, hope to adopt.
