Z-Wave is a wireless communications specification designed to allow devices in the home (lighting, access controls, entertainment systems and household appliances, for example) to communicate with one another for the purposes of home automation.-Wave is designed to provide reliable, low-latency transmission of small data packets at data rates up to 100kbit/s, unlike Wi-Fi and other IEEE 802.11 -based wireless LAN systems that are designed primarily for high data rates. Z-Wave operates in the sub-gigahertz frequency range, around 900 MHz.
