IEEE 802.16 is a type of network connection that lets different devices on the same network communicate with each other. This type of network connection is often used for things like Wi-Fi connections, which allow you to connect to the Internet on devices like your phone or computer. Devices on a IEEE 802.16 type of network use radio waves to communicate with each other, like two-way radios you might have seen. This type of connection is faster than some other types of network connections and works over longer distances.
