Abstract: When wireless terminal A and wireless terminal B respectively transmit signals (T123, T133), and Access Point (AP) in the wireless LAN system recognizes occurrence of contention, if AP successfully recognizes an address of sending source of this signal and a duration of this signal as a result of analyzing any signal from the wireless terminal A, AP transmits a CTS signal which gives a clearance for transmission to the wireless terminal A which is the source of sending the signal (T113). The wireless terminal A which is given the clearance for transmission by the CTS signal, resends a signal identical to the one previously sent (T127), whereas the wireless terminal B which is not given the clearance for transmission by the CTS signal withholds a signal transmission during the duration indicated by the CTS signal.

Abstract: A wireless LAN communications system with high transmission efficiency is provided. When a first wireless terminal normally receives a Data1 signal from an access point, the wireless terminal transmits an ACK signal. In the case where the wireless terminal has transmission data, the client transmits a Data2 signal to the access point after an SIFS interval. Meanwhile, when the access point or a second wireless terminal receives the ACK signal from the first wireless terminal, the second client waits a (DIFS+random number) interval, in accordance with the IEEE 802.11 standard. As a result, the first wireless terminal is able to transmit the Data2 signal with priority, without interference from signals from other devices.

Abstract: The present invention is to provide a wireless LAN system which achieves a relatively effective use of communication band, while suppressing occurrence of hidden terminal problems. When wireless terminal A and wireless terminal B respectively transmit signals (T123, T133), and Access Point (AP) in the wireless LAN system recognizes occurrence of contention, if AP successfully recognizes an address of sending source of this signal and a duration of this signal as a result of analyzing any signal from the wireless terminal A, AP transmits a CTS signal which gives a clearance for transmission to the wireless terminal A which is the source of sending the signal (T113). The wireless terminal A which is given the clearance for transmission by the CTS signal, resends a signal identical to the one previously sent (T127), whereas the wireless terminal B which is not given the clearance for transmission by the CTS signal withholds a signal transmission during the duration indicated by the CTS signal.

Abstract: To reduce load on an access point even if a large number of wireless stations are located very close to the access point. An access point detects a communication load value (S1 and S2) and reports it to wireless stations (S3). The access point waits for a predetermined time after the transmission of the communication load value (5) and detects a communication load value again (S6 and S7). The access point determines whether the first communication load value is larger than a predetermined value K (S4) and whether the second communication load value is larger than K (S8). If the first and second communication load values are larger than K, the access point outputs a warning output command instructing the wireless stations to output a warning prompting their users to move away from their current locations (S9).
