The power consumption is low, but the network delay is high.
1. Users or groups who want to upgrade and rebuild smart door locks for new, second-handed, and rented houses to meet their security, convenience, and permission sharing requirements
2. Product requirements of China's three major operators, operators outside China, and hotel and apartment industry customers in and outside China
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.
It can be used in houses and apartments in China.
