NB-IoT Used for Smart Lock Application in Smart HomeTime：2019-02-26 Source：
With the popularity of the smart home industry in recent years, the frequency of smart locks appearing in life is getting higher and higher. At
present, smart locks use non-mechanical keys as the technology for user identification ID. Mainstream technologies include proximity cards,
fingerprint recognition, and passwords recognition, facial recognition, etc., greatly improve the security of the access control, but the premise
of the above security is that in the power-on state, the smart lock is ineffective if it is in the power-off state.
In order to improve security, the smart lock has a built-in battery, collects basic data, and transmits data to the server.
Collecting abnormal data automatically alerts the user. Because the smart lock is not easy to disassemble after installation, the smart lock
battery is required to have a long service life; if the door is in a closed corridor, stronger signal coverage is needed to ensure real-time
transmission of network data. There are a large number of smart home terminals, and it is necessary to ensure a sufficient number of connections;
the most important thing is to ensure that the equipment cost is controlled within an acceptable range after adding the above functions.
Application of NB-IoT technology to smart home systems
NB-IoT features low power consumption and can be used for up to ten years with only two AA batteries, greatly reducing post-maintenance costs.
Super signal coverage, covering the indoor and basement, ensures signal stability.
A large number of connections to meet the simultaneous connection of multiple terminals in the smart home.
Low cost, a single NB-IoT chip is low in price.
