Range
Short range: Covers distances up to a few tens of meters. Examples include Bluetooth and Visible Light Communications (VLC), typically found in smaller IoT installations. Wireless short-range technologies often serve as alternatives to serial cables. Medium range: Extends from tens to hundreds of meters, with a maximum distance generally less than 1 mile. This is a primary category for IoT access technologies, encompassing Wi-Fi, IEEE 802.15.4, and 802.15.4g WPAN, as well as wired technologies
