2.7.2 Wi-Fi Device
Depending on the environment in which Raspberry Pi is installed, when Raspberry Pi requires a network connection function, there are many cases where it is more advantageous to connect wirelessly than to connect by wire.
From the Raspberry Pi 3 model B, Raspberry has built-in Wi-Fi that supports 802.11 b/g/n wireless LAN. Therefore, you can wirelessly connect to the LAN network without using additional Wi-Fi access devices and utilize the communication function.
To use Wi-Fi, you need to make some settings. Please refer to the description in [11.5 Wireless Connection] for more information.
