Abstract
A system and method for populating a map database for a vehicle navigation system with the location and type of wireless access points that can be used to update or service wireless systems on the vehicle. The map database can be initially populated with the known wireless access points at the time of manufacture of the vehicle, and then the vehicle communications system can detect new wireless access points as the vehicle travels, which can be stored on the map database. By storing the location and type of the access points in the map database, the vehicle will know the direction of the access point relative to the vehicle, and can compensate for the Doppler shift as a result of the relative movement of the vehicle to the access point.
Claims20
A method for providing wireless services for a vehicle, said method comprising:
- providing a map database on the vehicle;
- and
- populating the map database with the location and type of a plurality of wireless access points existing along a roadway where the wireless access points provide wireless communications to the vehicle.
A method for providing wireless services for a vehicle, said method comprising:
- providing a map database on the vehicle associated with a vehicle navigation system;
- populating the map database with the location and type of a plurality of public-use wireless access points existing along a roadway on which the vehicle may travel where the wireless access points provide wireless communications to the vehicle, where populating the map database includes initially storing the location of the wireless access points in the map database when the vehicle is manufactured and detecting wireless access points as the vehicle travels along the roadway and storing the location of the wireless access points in the database when they are detected;
- and
- correcting a Doppler shift caused by the motion of the vehicle relative to an access point.
A system for providing wireless services for a vehicle, said system comprising:
- a map database on the vehicle;
- and
- means for populating the map database with a plurality of public use wireless access points existing along a roadway where the wireless access points provide wireless communications to the vehicle, said means for populating the map database includes detecting the access points as the vehicle travels.
