HAN Home Area Network

A home network or home area network (HAN) is a type of computer network that facilitates communication among devices within the close vicinity of a home. Devices capable of participating in this network, for example, smart devices such as network printers and handheld mobile computers, often gain enhanced emergent capabilities through their ability to interact.

A home-area network (HAN) connects in-home digital devices, such as PCs, mobile phones, entertainment technology, thermostats, home security systems and smart appliances, into a common network. In the context of energy utilities, HAN is a means for utility companies to extend their reach beyond the meter, and to incorporate the “smart thermostat,” direct load control appliances, smart appliances and in-home energy display into utility systems, as well as to enable demand response (DR) and energy efficiency programs.
