无线ZigBee智能能源钥匙转换
虽然许多人认为交流电网是最普遍的数据网络，但电力线网络尚未广泛成功。现在，配电部门正在考虑在电表和能源消费品（如家用电器）中增加智能，他们需要一种无处不在的通信方案来实现智能电网。看来，ZigBee智能能源标准将是答案，无线通道将是一个关键，虽然新的智能能源协议可能最终运行在多种网络类型之上。

ZigBee began as a low-power standard for wireless personal-area networks. It is based on the IEEE 802.15.4 standard and promulgated by the ZigBee Alliance （www.ZigBee.org）。 The mesh-networking-capable technology targets home automation and industrial networks.
The ZigBee Alliance has essentially completed the ZigBee Smart Energy Version 2.0 specification. The Version 2.0 spec is at the 0.9 draft level， and the ZigBee Alliance is no longer accepting public comments. ZigBee Smart Energy is poised to be the de facto standard for home-area networks （HANs）。 The standard is based on the Internet Protocol （IP）， and the ZigBee Alliance has developed the standard with input from other organizations， including NIST （National Institute of Standards and Technology）， the HomePlug Powerline Alliance， the Wi-Fi Alliance， and others.
