- Use Cases: Commonly used for wireless control and monitoring in smart homes.
-
Z-Wave
- Definition: A proprietary technology operating in the 908/915 MHz band in the U.S. and 868 MHz in Europe, Z-Wave is primarily used for home automation.
- Use Cases: Widely adopted in smart home applications for lighting and security systems.
-
Cellular Low-Power WAN Technologies (NB-IoT, LTE-M)
- Definition: These standards provide solutions for cellular IoT applications, coexisting with 5G technologies for enhanced connectivity.
- Use Cases: NB-IoT is suited for smart agriculture and smart cities, while LTE-M is ideal for real-time applications in logistics and healthcare. In factory automation production process, wireless communication technologies such as NB-IoT and LTE-M are particularly effective for remote monitoring and diagnostics of fin press machines, enabling technicians to access real-time equipment status and data for troubleshooting and repairs.
-
Non-Cellular Low-Power WAN Technologies (LoRaWAN, Sigfox)
- Definition: LoRaWAN is an open-source protocol for low-power wide-area networks, while Sigfox is a proprietary technology.
- Use Cases: Commonly used in smart city applications, such as utility meters and asset tracking.
