# IoT Wireless Technologies - Besides Wi-Fi and Bluetooth: - **Z-wave** and **Zigbee** are two other wireless technologies commonly used by smart locks, smart light bulbs, and other IoT smart home devices. - Facts about Z-Wave and Zigbee: - Z-wave transmits around the 900-MHz band and requires less power than Wi-Fi. - Zigbee operates in either the 2.4-GHz band or the 900-MHz band, requires less power than Wi-Fi, and generally reaches a range of about 20m inside. - Z-Wave and Zigbee are not compatible. - Both Z-Wave and Zigbee devices can connect in a mesh network. - Typically, Zigbee and Z-Wave compete about equally for the smart home device wireless standard of choice. - Another standard used in the IoT industry is **RFID** (radio-frequency identification)
