Wireless station apparatus, wireless communication system, and wireless communication control method

A wireless communication system that includes a first wireless station apparatus and a second wireless station apparatus, wherein:

• said first wireless station apparatus comprises transmission unit that transmits signals;
• and
• said second wireless station apparatus comprises:
• an antenna for which the direction of directivity can be adjusted;
• a communication unit that receives signals by way of said antenna;
• a detection unit that detects the direction of arrival of signals that are received by said communication unit;
• a determination unit that determines whether the transmission origins of signals that are received by said communication unit are permitted wireless station apparatuses for which connection is permitted or nonpermitted wireless station apparatuses for which connection is not permitted;
• and
• an adjustment unit that, based on signals received by said communication unit and determination results of said determination unit, finds the degree of interference of said permitted wireless station apparatuses and said nonpermitted wireless station apparatuses in the direction of arrival that was detected in said detection unit and adjusts the direction of directivity of said antenna according to the degree of interference that was found.

A wireless communication control method that is realized by a wireless station apparatus that includes an antenna for which the direction of directivity can be adjusted, comprising:

• receiving signals by way of said antenna;
• detecting the direction of arrival of signals that are received;
• determining whether the transmission origin of signals that are received are permitted wireless station apparatuses for which connection is permitted or nonpermitted wireless station apparatuses for which connection is not permitted;
• and
• based on said determination results and said signals, finding the degree of interference of said permitted wireless station apparatuses and said nonpermitted wireless station apparatuses in said direction of arrival that was detected and adjusting the direction of directivity of said antenna according to the degree of interference that was found.

A recording medium readable by computer and storing therein a program for causing a computer that is connected to an antenna for which the direction of directivity can be adjusted to execute:

• a communication process of receiving signals by way of said antenna;
• a detection process of detecting the direction of arrival of said signals that are received;
• a determination process of determining whether the transmission origins of said signals that are received are permitted wireless station apparatuses for which connection is permitted or nonpermitted wireless station apparatuses for which connection is not permitted;
• and
• an adjustment process for, based on the determination results and said signals, finding the degree of interference of said permitted wireless station apparatuses and said nonpermitted wireless station apparatuses in said direction of arrival that was detected and adjusting the direction of directivity of said antenna according to the degree of interference that was found.
