Abstract

The invention provides a communication interference detection system and method for a wireless product. Before a 2.4G wireless product is put into use, interference on the communication frequency band and communication space of the 2.4G wireless product is simulated by distributing a Wi-Fi signal interference source around the product and covering an entire 2.4G public frequency band so as to detect the same-frequency-band wireless interference situation of the 2.4G wireless product in the surrounding environment, so that the working state of the 2.4G wireless product under same-frequency-band wireless interference is reflected. Testing is performed in advance to take necessary measures in time before the product is put into use so as to avoid the wireless interference, so that future normal use of the product is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a detection system and method for interference encountered by wireless product communication. Background technique [0002] In the prior art, since the 2.4G frequency band is an open public frequency band, many wireless products will use this frequency band for communication, such as Bluetooth, Wi-Fi, ZigBee, wireless USB (WirelessUSB), homeRF and other 2.4GHz special protocol application products . At the same time, when various 2.4G wireless products are used in the same space at the same time, there will be mutual interference, which will affect the normal use of the products. [0003] Therefore, there is a need for a communication interference detection system and method for 2.4G wireless products, which can reliably detect that the 2.4G wireless products are subject to wireless interference in the same frequency band in the surrounding environment before the ...
