Abstract

The wireless LAN system 10, which permits data communication with interconnection of a PC or the like, comprises a wireless LAN driver 20 including a time zone data table part 21 with time zone data stores therein, a member country deciding part 22 for deciding a member country in each time zone, an individual presetting data table part 23 with individual country presetting data stored therein, and a device driver part 25 preset based on data from the presetting part 24. This wireless LAN system permits easy coping with a wireless specification difference in each country or geographic location when the user makes it possible to do communication by interconnecting a PC or the like via wireless LAN.

Claims

1. A wireless LAN system permitting wireless communication of the user with portable communication device, wherein:

the user'"'"'s location is determined based on time zone data possessed by an OS (operating system) mounted on the portable communication device, and a country mode of a preset country corresponding to the user'"'"'s location is determined.

2. The wireless LAN system according to claim 1, wherein a station check is made whether the preset country is employs an FH system or a DS-SS system, and the country mode is determined for each system.

3. The wireless LAN system according to claim 1, wherein when a plurality of countries are present in each time zone, candidate countries are displayed on the display of the portable communication device for the user'"'"'s selection of one of these candidate countries.

8. The wireless LAN system according to claim 1, wherein the time zone data are stored together with world map in the time zone data table part, and are displayed on a display of the PC or the like in response to a user'"'"'s request.

9. The wireless LAN system according to claim 1, wherein the portable communication device is personal computer.

4. A wireless LAN system permitting wireless communication of the user with portable communication device via a wireless LAN (local area network) having country mode which is different with different countries, wherein:

the portable communication device includes a time zone data table with time zone data stored therein and an individual country presetting data table with individual country presetting data stored therein, and the wireless LAN system further comprises a wireless LAN driver for setting the country mode and a wireless LAN hardware module for realizing the presetting contents of the wireless LAN driver.

5. The wireless LAN system according to claim 4, wherein the wireless LAN driver includes a member country deciding part for deciding a member country based on time zone data of the time zone data table part, a presetting part for reading out and presetting the pertinent country mode of the individual country presetting data table part based on the decision result of the member country deciding part, and a device driver part for receiving an adaptive command of presetting contents transmitted from the resetting part.

6. The wireless LAN system according to claim 4, wherein the time zone data are stored together with world map in the time zone data table part, and are displayed on a display of the PC or the like in response to a user'"'"'s request.

7. The wireless LAN system according to claim 4, wherein the portable communication device is personal computer.
