Reliability

In a wireless network, it is important to ensure reliable communications - that is, to make sure communications reach their destinations uncorrupted. Corruption or loss of messages could result, for example, from radio interference or from poor transmission/reception conditions.

The reliability measures employed by ZigBee allow a wireless network to operate in a protected environment, even when there are other ZigBee networks nearby operating in the same frequency band. Adjacent ZigBee networks will not interfere with each other. In addition, ZigBee networks can operate in the neighbourhood of networks based on other standards, such as Wi-Fi and Bluetooth.

The techniques employed by ZigBee to ensure reliable communications are described on the next page.
