Abstract
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, determining a minimum received signal strength indicator (RSSI) value from a plurality of RSSI values corresponding to the workstations to serve as an upper bound of CCA threshold value and dynamically adjusting the present CCA threshold value according to the transmission error rate and the upper bound of CCA threshold value.
