If the current position of the wireless unit is within the access enabled area for the wireless unit, access if permitting to the information unit by the wireless unit. If the current position of the wireless unit is outside the access enabled area for the wireless unit, access to the information unit is denied by the wireless unit even if the current position of the wireless unit is within the range of communicable area of the access point.
