wifi wireless network topic

WIFI is the most widely used wireless network transmission technology today. In fact, it converts wired network signals into wireless signals for reception by related computers, mobile phones, PDAs, etc. that support its technology. If your mobile phone has a WIFI function, you can surf the Internet without going through China Unicom's network when there is a WIFI wireless signal, thus saving on traffic charges. But WIFI signals are also provided by wired networks, such as ADSL at home, residential broadband, etc. As long as you connect a wireless router, the wired signals can be converted into WIFI signals. In many developed foreign countries, cities are covered with WIFI signals provided by the government or large companies for residents to use.
