ZigBee-ready modules for sensor networking

Fully functional ZigBee-ready modules have been designed, implemented, and tested. One of the modules consists of both the IEEE 802.15.4 PHY/MAC and ZigBee networking stack layers, while the other module consists of only the IEEE 802.15.4 PHY/MAC stack layers. Furthermore, a ZigBee based testapplication for temperature sensor networking has been evaluated by utilizing the developed ZigBee-ready modules. The modules can have a line-of-sight radio link up to 180 m, when having only 1-mW output power. It is shown that ZigBee is suitable for sensor networking where long battery life, large networks, and fast network establishment are the requirements.
