NB IOT is a narrowband Internet of Things technology that mainly solves low-rate data transmission. It can use GSM900 or DCS1800 frequency bands. It is more flexible in frequency band use and can coexist with GSM, UMTS or LTE. It has excellent MCL (Minimum Coupling Loss), It has a large coverage area, low power consumption, has the silent function when idle, and supports a large number of connections at the same time. On 4G, there is also the Internet of Things standard LTE-M. On 5G, the Internet of Things scene standard is mMTC
