FIELD: information technology. ^ SUBSTANCE: in a wireless LAN, the ACK (acknowledgement signal) transfer rate between AP (access point) and STA (mobile terminal station) there is alternate control based on the number of repeated transmission of snaps of user data. The number of repeatedly transferred snaps is calculated and, if the value is exceeds a predetermined value M, the ACK transfer rate is lowered by one level. The number of successful snaps coming one after the other is calculated and, if the value exceeds a predetermined value N, the transfer rate is raised by one level. ^ EFFECT: high transfer rate of data in a descending channel does not depend on the ACK transfer rate and the limited frequency band of the wireless network is used effectively. ^ 13 cl, 5 dwg |
