The radio network ZigBee is universal, economical, self managing. The specifications are based on the
IEEE 802.15.4 for Wireless Personal Area Networks (WPANs).
For the transmission range of such a radio network there are only rough estimations based on experience of the local conditions. This is especially relevant when installed in buildings. Our tests in a free field (without obstructions) have shown a transmission range of approx. 300m when used together with the ASmicro. It is quite possible that there is still a radio reception registered at greater distances but quite possible that this is unreliable.
The ZigBee radio module in the ASmicro works as a router for the connection sensors and actuators.
