Technical Field
The invention belongs to the technical field of communication, and particularly relates to a data transmission mode selection method, a data transmission control platform and a data transmission control system.
Background
With the rapid development of the information society, people have stronger and stronger requirements on wide range, long distance and low power consumption, and the method is particularly prominent in the fields of cargo tracking, health monitoring and intelligent meter reading. There are two major dominant technologies for low power wan, LoRa and NB-IoT. Where LoRa is an ultra-long distance, low power consumption internet of things solution offered by Semtech corporation. The LoRa physical layer can improve the sensitivity of the receiver by using a spread spectrum technology, and each LoRa base station can cover 2-5 kilometers in urban area and 10 kilometers in rural area. And the NB-IoT is mainly pushed by communication operators and equipment vendors, and the technical effect is similar to that of LoRa.
However, currently, both LoRa and NB-IoT have a problem of being unable to continuously cover. Specifically, in china, because LoRa is not an operator-level network provided by an operator, the coverage area of LoRa is limited, and it cannot be guaranteed that the LoRa private network can achieve seamless coverage like a wide-area 4G network provided by the operator. The NB-IoT is a network provided by the operator, but due to the characteristics and cost of the service of the internet of things, the operator cannot achieve continuous coverage as in the 4G network, and especially has a risk of no coverage in non-hotspot cities and regions. Therefore, as a service provider, for some services that need continuous coverage, such as tracking and positioning of important goods, it is necessary to integrate the chips of LoRa and NB-IoT at the terminal and perform corresponding optimization at the platform side.
