Abstract

The invention provides a frequency sweeping method for the internet of things and a frequency sweeping instrument. In the practical use, the frequency sweeping instrument can be continuously moved, for instance, to be placed on a mobile vehicle so that the frequency sweeping instrument can detect the narrow-band internet-of-things modulation signal generated by a base station at different geographical positions. The frequency sweeping instrument obtains the pilot signal through the main synchronization position where the main synchronization signal in the data frame is located and obtains the cell identification ID at the auxiliary synchronization position where the auxiliary synchronization signal in the data frame is located so as to determine the intensity of the received signal corresponding to the cell identification ID. The cell identification ID and the intensity of the received signal corresponding to the cell identification ID is transmitted to a remote terminal. The remote terminal is capable of analyzing the intensity of the signal transmitted from the base station as well as the coverage scope of the signal.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically to a frequency scanning method and a frequency scanning instrument for the Internet of Things. Background technique [0002] A base station is a form of a radio station, which refers to a radio transceiver station that transmits information to and from terminal equipment through a mobile communication switching center in a certain radio coverage area. The performance of the base station is reflected by the strength and coverage of the signal generated by the base station. NB-IoT is a new system of base stations. As a type of cellular Internet of Things, base stations of the narrowband Internet of Things standard have been deployed in a large number of commercial trials. [0003] However, there is currently no detection method for the strength and coverage of the narrowband IoT standard signal generated by the base station. Contents of the invention [0004...
