Here you have to enter the exact geographic position of your WLAN-router.

Values for Latitude (the geographical degree of latitude in range -90..+90 degrees) and Longitude (the geographical degree of longitude in range -180..+180 degrees) can be evaluated using e.g. a GPS-device. Depending on that device it may be necessary to convert the given position value when the device uses a different format for the position. Alternatively you can use the OpenStreetMap to find your exact position completely without a GPS-device.
