What are the advantages of NB-IoT smart door locks?

1. Simplified configurations: NB-IoT smart door locks are easy to install and maintain. No gateway configuration or network pairing is required. The door locks can automatically connect to a network and can be used out of the box. 2. Ultra-low power consumption: In NB-IoT PSM mode, the static current of an NB-IoT smart door lock is 50 mA. 3. Large number of connections: The operator's network is stable and reliable. Theoretically, a base station can connect to 600,000 devices. 4. Wide coverage: NB-IoT improves the gain by 20 dBm when compared with 2G and is applicable to parking lots and basements. 5. Time synchronization: The NB-IoT module is embedded with the RTC function.
