DetailsLTE Cat-NB1, also called NB-IoT, requires a bandwidth of about 200KHz, and mainly transmits low-traffic data at a rate below 100Kbps.
DetailsEdge computing means that in the vicinity of the data source, the IoT edge gateway lays a solid foundation for the application of edge computing in the Internet of Things, and the deployment of edge computing services in the fields of the Industrial Internet and the Internet of Things. Edge computing is the infrastructure of edge computing gateways, enabling developers to quickly develop and deploy applications.
DetailsDBi and dBd are units of power gain, both are relative values, but the reference is not the same. The reference reference for dBi is an omnidirectional antenna; the reference reference for dBd is a dipole.
DetailsWe know that data collection by positioning devices requires traffic, but the data is not too much. Even if the 3G network is enough for devices to buffer and transmit these data, a problem we need to consider is that telecom operators will not stop technology just because this field can be used. The pace of progress, I think one day the 3G network will also be eliminated.
