Two new standards from the ZigBee Alliance are a great fit for lighting applications: Light Link and ZigBee IP. Based upon the IEEE 802.15.4 standard for personal area networks, ZigBee works in the 2.4-GHz unlicensed industrial, scientific, and medical (ISM) band and adds extra layers to the protocol to implement wireless mesh networks.
Light Link is a ZigBee application as well as an open global standard designed for consumer lighting and control products. It lets consumers implement wireless control over all of their LED fixtures, light bulbs, timers, remote controls, and switches (see the figure). For example, they can easily change lighting remotely to develop the right environment for ambiance or a task. It also helps manage energy consumption.
