<p><P>PROBLEM TO BE SOLVED: To automatically revise a wireless LAN communication mode in matching with a wireless specification of each country. <P>SOLUTION: A computer apparatus 10 has a current position data output unit 13 and an area data output unit 14 responsive to current position data from the current position data output unit 13 for outputting specific country data representative of a specific country including a current position. A wireless LAN connecting unit 12 is preliminarily given a plurality of wireless communication modes corresponding to a plurality of country data. Upon receipt of the specific country data, the wireless LAN connecting unit automatically sets, as a selected communication mode, one of the wireless LAN communication modes which corresponds to the specific country data and carries out transmission/reception via a wireless LAN 11 in the selected communication mode. Each of the wireless LAN communication modes is determined by a radio frequency channel and a transmit power level used in a country represented by the country data. The wireless LAN connecting unit 12 carries out transmission / reception by the radio frequency channel and the transmit power level deciding the selected communication mode. <P>COPYRIGHT: (C)2004,JPO</p> |
