Zigbee targets Internet of Things

The Zigbee Alliance has published its latest spec allowing huge numbers of Zigbee devices to directly connect which is seen necessary for future Internet of Things (IoT) applications.

Zigbee (the path a bee flies) is an IEEE standard (IEEE 802.15.4) and the new IP Direct Internet Connection addition adds support for network and security layers and an application framework that is scalable with IPv6 connected devices. The Zigbee Alliance state it is the first IPv6 open wireless mesh standard.

The main advantages of Zigbee against other systems is that it's very low power, automatically meshes new nodes and supports a wide range of standards such as 6LoWPAN, IPv6, PANA, RPL, TCP, TLS and UDP as well as supporting end-to-end encryption. It operates in the licence exempt 2.4GHz band as well as other bands in other regions.
