ACCESS POINT WITH CAPABILITY OF DYNAMICALLY ADJUSTING CURRENT CCA THRESHOLD VALUE AND OPERATING METHOD THEREOF

摘要

An access point with capability of dynamically adjusting a present clear channel assessment (CCA) threshold value and an operating method of the access point are disclosed herein. The operating method includes, sensing a channel status through a receiving module, determining whether to transmit data through a transmission module according to the channel status and the present CCA threshold value, calculating a transmission error rate according to the data is successfully transmitted through the transmission module or not, and dynamically adjusting the present CCA threshold value according to the transmission error rate. In such an operation, the present CCA threshold value can be adjusted to a suitable value, and the access point can avoid abandoning its data transmission task due to the interferences of wireless signals from other access points or workstations located beyond the cell size of the access point.

1. An operating method applied to an access point, wherein the access point is configured to be connected with a plurality of workstations, and the access point comprises a transmission module and a receiving module, the operating method comprising following steps:
sensing, through the receiving module, a channel status of a transmission channel between the access point and the workstations; determining whether to process a data transmission task through the transmission module according to the channel status and a present clear channel assessment (CCA) threshold value; calculating, through the transmission module, a transmission error rate according to the fact that the data transmission task succeeds or not; and dynamically adjusting the present CCA threshold value according to the transmission error rate.
