There are many old public spaces in the cities, such as old apartments, small restaurants, cafes, etc. These areas are the ones for which the government is the most concerned about, because the risk of fire is significantly higher than for other areas. But these places are usually too old and are hard to reach locations, so it is hard to use traditional smoke detector using cables.
The NB-IoT smoke detector is easy to install (no need for cabling) and plug to play. It has very low power consumption. A battery with less than 3000mAh capacity supports 3~5 years of operations. Usually, buildings have some places such as basement and corners with bad network coverage. By using NB-IoT smoke detectors, there will be no blind area.
There are two different business models for the smoke detection’s use case.
1. For the sale model, the mobile operator provides SIM cards to the device company, and the device company produces the device and pays the connection fee to the mobile operator. The device company sells the smoke detector and service to the end customer who should pay the device and the service fee to the device vendor.
2. For the rental model, the mobile operator provides SIM cards to the device company, and the device company produces the device and sells it to the mobile operator, it also provides the service to the mobile operator. End customers will usually be regional governments and apartment or store owners, they only need to rent the smoke detectors from the mobile operators
