Antenna Switching Control For AOA Capturing In Phone-As-A-Key Systems With De-Whitened Tone Transmission, CRC Based Validation And Event Timing - A simplified explanation of the abstract
This abstract first appeared for US patent application 18614309 titled 'Antenna Switching Control For AOA Capturing In Phone-As-A-Key Systems With De-Whitened Tone Transmission, CRC Based Validation And Event Timing
The abstract describes a patent application for a system that includes a reader with a transceiver and a control module. The transceiver monitors notification messages between a portable access device and a phone-as-a-key system in a vehicle during a connection event. The control module captures and analyzes the notification messages to determine the angle-of-arrival of the messages and communicate this information to the phone-as-a-key system for access control purposes.
- The system includes a reader with a transceiver and a control module.
- The transceiver monitors notification messages between a portable access device and a phone-as-a-key system in a vehicle during a connection event.
- The control module captures and analyzes the notification messages to determine the angle-of-arrival of the messages.
- The angle-of-arrival information is then communicated to the phone-as-a-key system for access control purposes.
- The system uses fields in the notification messages, including a mobile de-whitened section with consecutive bits of zeros or ones, to perform in-phase and quadrature phase capture.
Potential Applications: - Vehicle access control systems - Security systems for buildings and facilities - Smart home technology
Problems Solved: - Enhances security by accurately determining the angle-of-arrival of notification messages - Improves access control for vehicles and other secure areas
Benefits: - Increased security and access control accuracy - Enhanced user experience with seamless access to vehicles and buildings
Commercial Applications: Title: Advanced Access Control System for Vehicles and Buildings This technology can be used in automotive industry for keyless entry systems, as well as in building security systems for access control.
Questions about the technology: 1. How does this system improve security in comparison to traditional access control methods? 2. What are the potential challenges in implementing this technology in different environments?
Original Abstract Submitted
A reader includes a transceiver and a control module. The transceiver is configured to, during a current connection event, monitor notification messages transmitted from a portable access device to a phone-as-a-key (PaaK) system of a vehicle, where the notification messages are transmitted to establish a communication link between the portable access device and the PaaK system. The control module is configured to: perform an in-phase and quadrature phase capture of the notification messages based on fields in one or more of the notification messages, where the fields include a mobile de-whitened section including two or more series of consecutive bits, where the consecutive bits in each of the one or more series are all zeros or all ones; based on the in-phase and quadrature phase capture, determine an angle-of-arrival of the notification messages, and indicate the angle-of-arrival to the PaaK system for permitted access determined by the PaaK system.
