[Object] To provide a novel and improved communication system and communication device that make it possible to reduce an amount of time from when communication with an external device is completed to when communication data corresponding to a communication result is output to another device.

[Solution] Provided is a communication system including: a communication device configured to transmit a selection solution that is selected depending on a result of first communication with an external device; and a control device configured to receive the selection solution from the communication device through second communication between the communication device and a communication partner that is different from the external device serving as a communication partner in the first communication.

A reader system for an access control system includes first and second antennas and first and second controllers. The first controller is configured to communicate with a credential device using a first communication protocol via the first antenna to exchange a credential with the credential device. The second controller is configured to communicate with the credential device using a second communication protocol via the second antenna to perform ranging for the credential device and is configured to communicate with the first controller via a communication link.

The invention relates to a locking system (3), in particular for providing authorization to access and/or drive of a motor vehicle (1) in the manner of a keyless entry/go functionality. The locking system (3) comprises a first device (4), having at least two states and being configured as a control system, such as a control system for releasing and/or locking the car doors (6), the ignition lock, the steering wheel lock, for releasing and/or blocking the immobilizer, the motor control device or the like, and an associated second device (5) in the form of an electronic key, an ID transmitter, a chip card or the like. Both devices (4, 5) comprise for the operation thereof transmission and/or receiving units for the transmission of in particular electromagnetic signals (7), wherein the transmission and/or receiving unit has an antenna for transmitting the signals (7). At least one of the signals (7) transmitted between the second device (5) and the first device (4) is a coded operating signal for authenticating said second device (5) in such a way that once the transmitted operating signal has been positively identified for the authorized second device (5), the state of the first device (4) can be modified. The transmission and/or receiving unit (10) for the first device (4) comprises two antennae (11, 12). Furthermore, a signal distributor (13) in the form of a power splitter is provided for both antennae (11, 12). The transmission and/or receiving unit (10) is in communication with both antennae (11, 12) via the signal distributor (13).

Systems and techniques for a physical access control systems with localization-based intent detection are described herein. In an example, an access control system may regulate access to an asset. The access control system is adapted to establish a first connection with a key-device. The access control system may be further adapted to receive a credential for a user over the first connection. The access control system may be further adapted to establish a second connection with the key-device. The access control system may be further adapted to determine an intent of the user to access the asset. The access control system may use location data derived from the second connection to determine the intent of the user. The access control system may be further adapted to provide the credential to an access controller, based on identifying an intent of the user to access the asset.

The access control system is adapted to receive a credential of a user from a key device associated with the user using a first wireless connection. The access control system may be further adapted to establish a second wireless connection with the key device. The access control system may be further adapted to determine the user intends to access the asset based on a data set generated derived from the second wireless connection. The access control system may be further adapted to use a trained machine learning model to determine the intent of the user to access the asset. The access control system may be further adapted to transmit a command to grant access to the asset.

A system for includes master and sniffer devices. The master device includes: first antennas with different polarized axes; a transmitter transmitting a challenge signal via the first antennas from the vehicle to a slave device, where the slave device is a portable access device; and a receiver receiving a response signal in response to the challenge signal from the slave device. The sniffer device includes: second antennas with different polarized axes; and a receiver receiving, via the second antennas, the challenge signal from the transmitter and the response signal from the slave device. The sniffer device measures when the challenge signal and the response signal arrive at the sniffer device to provide arrival times. The master or sniffer device estimates at least one of a distance from the vehicle to the slave device or a location of the slave device relative to the vehicle based on the arrival times.
