Problems solved by technology

However, since the 2.4GHz frequency band is commonly used by various wireless devices, such as Bluetooth devices, home wireless phones and WLAN devices, when a WLAN wireless device operates in the 2.4GHz frequency band and uses a 40MHz transmission bandwidth, it will be vulnerable to other wireless devices using the same frequency band. The signal interference of wireless devices in the frequency band affects the transmission performance
In this case, if the interference problem cannot be effectively dealt with, the channel traffic of the WLAN wireless device using the 40MHz transmission bandwidth for signal transmission will be greatly reduced, and its channel traffic may even be lower than that of the channel using the 20MHz transmission bandwidth for signal transmission flow

Abstract

The invention discloses a wireless device and a disturbance judging method thereof. The wireless device works in a first bandwidth mode, and according to at least one received radio frequency signal, accounts first clear channel assessment (CCA) associated with a first main channel, the amount of second CCA associated with a sub-channel, the amount of integrated CCA associated with the main channel or the sub-channel or the main channel and the sub-channel, and the number of false alarms. Then, if the amount of the second CCA surpasses the sum of the amount of the first CCA and a deviation value, the wireless device judges that the wireless device is in a disturbance state, and judges that the disturbance state belongs to a first disturbance type or a second disturbance type according to the ratio of the amount of the integrated CCA and the number of the false alarms.

Description

technical field [0001] The invention relates to a wireless device and an interference judging method thereof. In particular, it refers to a wireless device capable of judging whether the wireless device is in the interference state, and then determining whether the interference state belongs to the first interference type or the first interference type and the interference judging method thereof. Background technique [0002] With the development of wireless local area network (wireless local area network; WLAN), in order to meet the demand of high throughput (TP), the Institute of Electrical and Electronic Engineers (IEEE) has formulated the latest wireless Network standard 802.11n. In addition to supporting the 20 megahertz (MHz) transmission bandwidth of the original 802.11abg specification, the 802.11n specification also supports a 40MHz transmission bandwidth, that is, the 802.11n specification uses two adjacent 20MHz channels as a 40MHz channel to increase channel tra...
