Abstract: An infrastructure-controller for an infrastructure. The infrastructure-controller configured to: send a ranging-scheduling-signal to a key, wherein the ranging-scheduling-signal comprises timing-information for a subsequent ranging operation; and activate one or more ranging nodes associated with the infrastructure, for receiving a key-ranging-signal from the key, at an infrastructure-node-start-ranging-time based on the timing-information. The ranging-scheduling-signal has a frequency in a first RF frequency range. The key-ranging-signal has a frequency in a second RF frequency range.

Abstract: Disclosed are: a mobile device, in particular a mobile Passive Keyless Entry, PKE, key device, and an associated method for providing 3D field values of a magnetic field H; an evaluation device for use in a PKE system having a Mobile device and an associated method for determining the direction of a magnetic field vector H=(x, y, z), which is present locally at a position of a 3D antenna of the mobile device; and a PKE system having a PKE base structure, to which preferably the mobile device is associated and which has at least a first base structure antenna, which is operable to emit the, particularly low frequency, magnetic field, the mobile PKE device and the evaluation unit. The mobile device and the associated method are characterized by providing, in addition to providing a first, second and third value vx, vx, and vx indicative of the local X-component x, Y-component y, and Z-component x of the magnetic field vector H, a sum value vS indicative of the sum |S|=|x+y+z| of the local X-, Y-, and Z-components of the magnetic field vector H. The evaluation device and the associated method are characterized by providing the vector V yielded as a vector, which has the direction of the magnetic field vector H, and may be capable to discriminate, if a one-dimensional Relay Station Attack has occurred or if a regular wireless connection has been established between the PKE base structure and the associated mobile device.

Abstract: A key fob including at least one wireless communication circuit, a power supply node coupled to provide power to the at least one wireless communication circuit, a battery node, a battery power circuit, and an inductive power circuit. The battery power circuit provides power when a battery with sufficient charge is provided. The inductive power circuit only provides power when energized with inductive power when the battery is not provided or is not sufficiently charged. The inductive power circuit may include a rectifier circuit and an inductor and may further include regulator circuitry. The inductive power circuit does not perform wireless communications thereby simplifying circuitry and operation of the key fob and a corresponding access system. Since only configured to transfer power, the inductive power circuit may be optimized for power transfer. The access system inductively couples power to the key fob when within a predetermined coupling zone distance.

Abstract: An ultra-wideband (UWB) wireless communication system, comprises a first wireless apparatus; a second wireless apparatus that participates in a first ranging sequence with the first wireless apparatus; and a transmission channel between the first and second wireless apparatuses that transmits data of the first ranging sequence. At least one of the first wireless apparatus or second wireless apparatus generating at least one channel impulse response (CIR) and determining from the at least one CIR whether the transmission channel includes a line-of-sight channel. A special purpose processor reduces a current performance level of at least one of the first and second wireless apparatuses during a second ranging sequence in response to a determination that the transmission channel includes the line-of-sight channel.
