Z-Wave is a wireless networking specification dominated by the Danish company Zensys. Z-Wave is an emerging short-range wireless communication technology based on radio frequency, low cost, low power consumption, high reliability and suitable for networks. The working frequency band is 908.42MHz, and the effective coverage of the 868.42MHz signal is 30m indoors and more than 100m outdoor, which is suitable for narrow bandwidth applications. Z-Wave technology is also a low-power and low-cost technology that strongly promotes low-rate wireless personal area networks.
