Wireless Personal Area Network (WPAN): A network for communica- tion and inter-connection of devices within a personal operating space, with emphasis on short-range, low power and low cost. Wireless Internet Service Provider (WISP): A public Internet service provider using wireless network connections to subscribers. Wireless Local Area Network (WLAN): A wireless network that uses licensed or unlicensed radio frequencies such as the 2.4 or 5 GHz ISM bands to connect wireless enabled computers or other devices in a local area extending typically over 10-100 metres. X-10: A power line based home automation technology, primarily used for lighting control. ZigBee: A wireless networking technology based on the IEEE 802.15.4 PHY and MAC standard, and aimed at short range, very low power and low data rate monitoring and control applications.
