School wifi can be used to limit the number of people using it by limiting the number of concurrent login accounts. The specific practice is to set the maximum number of devices that each account can log in to at the same time in the school's network management system, and when this number is exceeded, subsequent login requests will be restricted.
Similarly, schools can also control the number of times an account is used according to the time limit, such as setting a limit of five hours per day for each account, and then restricting subsequent requests when the time limit is reached. These restrictions can effectively avoid network congestion, ensure the fair distribution of network resources, and improve the efficiency of network use.
