I'm not sure about the specific scene, but I think the library will mainly involve borrowing and returning books, RFID tags, environmental monitoring and so on. It stands to reason that some picture information (such as book covers, etc. ), so the transmission rate is still required, and the delay in considering the efficiency problem should not be too great. The venue itself must emphasize low power consumption in communication.

In this case, narrowband low-power IOT communication such as LORA and NBIOT is not very suitable. This requires consideration of technologies such as WIFI, Bluetooth and zigbee. In this case, it is better to use WIFI, and you can also realize the WIFI coverage of the whole museum by the way.
