Home Area Network (HAN)
HAN is a network of energy management devices, consumer electronics, signal-controlled appliances, and applications within a home. It is the communication capability within a home. HAN specifications include Zigbee, HomePlug, Z-Wave, and Wireless M-Bus. Instead of a network of servers and computers, HAN connects devices that are capable of sending and receiving signals from a meter, in-home displays, and HEM applications.
