Japanese Patent JP2010516925
Kind Code:
A
Abstract:
An access facility for a vehicle has a first transmit/receive device for transmitting a first radio signal and for receiving a second radio signal, a second transmit/receive device for transmitting the second radio signal and receiving the first radio signal, a transmission strength determining device for determining a transmission strength value, which represents the transmission field strength of the first radio signal transmitted by the first transmit/receive device, and a reception strength determining device for determining a second reception strength value, which represents the reception field strength of the first radio signal at the location of the second transmit/receive device. The information content of the first radio signal has the transmission strength value, and the access facility features a relation determining device for determining a relation between the transmission strength value and the reception strength value.
