Do WIFI phones still use traffic?

As long as the Android phone is successfully connected to wifi, it will not use the data traffic of the phone.

Wi-Fi, the Chinese name for wireless fidelity, is a technology that can wirelessly connect terminals such as personal computers and handheld devices (such as PADs and mobile phones). It's actually a high-frequency radio signal.

Wireless security is really a brand of wireless network communication technology, which is owned by Wi-Fi Alliance. The purpose is to improve the interoperability between wireless network products based on IEEE 802. 1 1 standard. At present, most people will confuse Wi-Fi with IEEE 802. 1 1. Even equate Wi-Fi with wireless Internet access.

Wireless security is really networked through radio waves; Wireless router is common, so in the effective range of radio wave coverage of this wireless router, wireless fidelity connection can be used for networking. If a wireless router is connected to an ADSL line or other Internet access line, it is also called a hotspot.
