What is the Data Latency for ZigBee Networks?
top Sensor systems have a broad range of data-latency requirements. If sensor data are needed within tens of milliseconds, as opposed to dozens of seconds, the requirement places different demands on the type and extent of the intervening network. For many sensor applications, data latency is less critical than battery life or data reliability. For simple star networks (many clients, one network coordinator), ZigBee can provide latencies as low as ~16 ms in a beacon-centric network, using guaranteed time slots to prevent interference from other sensors. You can further reduce latencies by several milliseconds if you forego the beacon environment and are willing to risk potential interference from accidental data collision with other sensors on the network. Data latency can also affect battery life. Generally, if you relax data-latency requirements, you can assume that the battery life of the client nodes will increase. This is even truer of network hubs, which are required to coordinat
