Problems solved by technology
[0002] The existing wireless routers have low power due to the limitation of radiation intensity. When the signal penetrates obstacles, the transmission power is weak, and it is not easy for the user terminal to connect to the network. For example, in the home environment or office environment, due to the wall In some locations, user terminals such as mobile phones or computers cannot connect to the wireless network. The existing solution is to increase the transmission power of the wireless router so that the wireless signal also has a strong power after penetrating obstacles. signal, but due to its high transmission power, it will be exposed to high electromagnetic pollution
Another method is to connect multiple routers in series for relay transmission. Although it solves the problem of high electromagnetic pollution, because it is relay transmission through routers, there are many overlapping areas of transmission signals, which is very easy to cause waste of resources.
In addition, the existing wireless routers do not have the audio playback function, the function is single, and it is inconvenient to use
