Abstract

The invention discloses a spatial interference detection method based on a 2.4 G frequency range. The method detects a 2.4 G frequency range through an interactive hand-held terminal device, and includes the steps of: setting the interactive hand-held terminal device to be in a frequency range detection mode; circularly detecting 11-26 frequency ranges; and obtaining the number and intensity of special interference factors, and displaying the number and intensity of special interference factors of all frequency ranges through the display module of the interactive hand-held terminal. The spatial interference detection method can directly detect spatial interference information through the interactive hand-held terminal device and in dependence on network node information and interference information, obtain an optimum wireless equipment installation position, and provide reference basis of the optimum wireless equipment installation position for clients in real system installation, and has the characteristics of simple operation and high efficiency.

Description

technical field [0001] The invention belongs to the field of wireless communication of the Internet of Things, and in particular relates to a space interference detection method based on a 2.4G frequency band. Background technique [0002] All over the world, the Internet of Things is developing vigorously. In the Internet of Things, the terminal fulcrums all use wireless signals to communicate. The biggest problem encountered when using wireless signals is interference, which is the focus of wireless communication. It is also difficult. The wireless signal that is often used in the Internet of Things industry is the 2.4g frequency band, and the 2.4g frequency band is divided into 16 frequency bands (11 to 26 frequency bands). When installing a test system, we must first check the 16 frequency bands In the end, choose a frequency band with the least interference to use. When detecting interference signals, we generally use a handheld spectrum analyzer. There are three main...
