The wireless communication method includes: the communication terminal device sniffs a radio signal, captures a packet from the radio signal, and determines whether the packet meets a source condition; the communication terminal device determines whether the packet meets a data condition if the source condition is met; the communication terminal device extracts a data payload from the packet if the data condition is met; the communication terminal device determines whether a data error rate of the data payload is greater than a tolerable value; the communication terminal device sends an error correcting information to a server if the error rate of the data payload is greater than the tolerable value, such that the server provides an error correction parameter for updating a forward error correction codding scheme to the wireless transmitting device. ## Claims ### Claim 1 A wireless communication method of a communication terminal device, the wireless communication method comprising: sniffing, by the communication terminal device, a radio signal and capturing a packet from the radio signal;
