Other knowledge of wireless network.

Wireless Internet access is widely used in big cities. Although the wireless communication quality transmitted by Wi-Fi technology is not very good, the data security performance is worse than that of Bluetooth, and the transmission quality needs to be improved, but the transmission speed is very fast, reaching 54Mbps, which meets the needs of personal and social informatization.

The main advantage of Wi-Fi is that it does not need wiring and is not limited by wiring conditions, which is very suitable for the needs of mobile office users. Moreover, because the transmitted signal power is lower than 100mw, which is lower than the transmitted power of mobile phones, Wi-Fi surfing the Internet is relatively the safest and healthiest.
