A method and apparatus includes a processor that receives information corresponding to a first signal strength of a communication link between a remote device and a communication gateway of a vehicle. The information corresponding to the first signal strength is associated with a first antenna of a sensor and the first antenna includes a first peak main lobe magnitude oriented in a first direction. The processor also receives information corresponding to a second signal strength of the communication link. The information corresponding to the second signal strength is associated with a second antenna. The second antenna includes a second peak main lobe magnitude oriented in a second direction. The processor executes a first boundary line determination that includes determining whether the remote device is located on a first side of a boundary line based on the first signal strength and the second signal strength.

The invention relates to a digital access system (1), an electric vehicle (100) with such an access system and a method (200) for granting an access authorization to an electric vehicle with such an access system, comprising an unlocking unit (11) for positioning in the vehicle (100), at least one access unit (12) and at least one activation unit (13) for use outside the vehicle (100), wherein the activation unit (13) activates the unlocking unit (11) by means of wireless data communication (21) to the unlocking unit (11) at least for a period, the access unit (12) arranging access arranging access to the vehicle (100) from the outside by means of an independent wireless data communication (22) separate to the previous data communication (21) with the previously activated receiving unit (11), wherein the unlocking unit (11) transmits control signals (14) to the system controller (110) in response to the data communication (22) with the access unit (12) for controlling the locking system and activating at least one locking component (140) for allowing access to the vehicle to its loading.

Method and apparatus are disclosed for mobile device tethering for vehicle systems based on variable time-of-flight and dead reckoning. An example vehicle includes a communication module to communicate with a mobile device using multiple frequency bands and a body control module. The body control module at an interval, estimates a location of the mobile device relative to the vehicle based on time-of-flight measurements using one of the multiple frequency bands selected based on a previous location estimate. Between the intervals, the body control module tracks the location of the mobile device using dead reckoning. Additionally, the body control system controls a subsystem of the vehicle based on the location of the mobile device.

Described herein is a wireless electronic lockset comprising a processing unit, a locking bolt, a motor, a wireless communication tag, and a wireless interface. The lockset is capable of connecting to a mobile device via a first communication protocol and/or a second communication protocol. The lockset sends a value to the mobile device via the first communication protocol and receives an actuation command via the second communication protocol if the mobile device has been verified by a server. The actuation command causes the lockset to lock or unlock the door.

Method and apparatus are disclosed for mobile device relay attack detection and power management for vehicles. An example vehicle includes a first module for first protocol communication, a second module for second protocol communication, and a controller. The controller is to determine a first distance to a mobile device utilizing a signal strength of the first protocol communication and determine, upon receiving an entry request, a second distance to the mobile device utilizing a time-of-flight of the second protocol communication. The controller also is to prevent entry when the second distance does not match the first distance.

An access control method for people in which the access control device (16) is assigned to an access point. Each access control device (16) has at least one antenna (1, 2, 8, 9, 10, 11), which emits beacons. Each access area (3) can only accommodate one person at a time. All antennas lie on an antenna plane. The transmitted beacons containing a unique access point ID, which positively identifies the access point and a unique antenna ID within predefined intervals. The received beacons are analyzed based on the RSSIs (Received Signal Strength Indicator) such that the distance of the mobile device (14) to the at least one antenna (1, 2, 8, 9, 10, 11) is determined. The received access point ID are transmitted to a server (15) or to the access control device (16) for analysis. Access is granted if the access authorization is valid for the access point ID.

The invention relates to a method (100) for an activation of at least one security function of a security system (200) of a vehicle (1), wherein an authentication at the security system (200) of the vehicle (1) is effected by means of a mobile identification transmitter (300).

Disclosed is a RF system (100) having at least one transceiver node device (110, 112, 114, 116, 118, 120) that is capable to assume, at a controllable point in time and/or for a controllable time period, each one of the following roles (210, 220, 230, 240): a first role (210) comprising listening or answering to a message from an active communication session, in particular ranging sessions, a second role (220) comprising listening for new communication sessions, in particular ranging sessions, a third role (230) comprising staying idle, and optionally a third role (230) comprising scanning for ongoing communication sessions, in particular ranging sessions, of other RF systems. The RF system (100) further comprises a controller device (134) communicatively interlinked with the at least one, in particular each, transceiver node device (110, 112, 114, 116, 118, 120) and capable to control an assignment of roles to the at least one, in particular each, transceiver node device, in particular to control for a transceiver node device a point in time to assume a role and/or a duration of performing a role and/or a duty cycle of performing a role (210, 220, 230, 240).

A vehicle access system includes an identification device with a first transceiver, a short-range transceiver and a processor configured to control the first transceiver and the short-range transceiver to activate the first transceiver only when a distance measurement between the identification device and a vehicle is within a predefined range as determined utilizing the short-range transceiver.

A smart thermostat hub and a management platform for controlling and securing smart devices in a multi-family residential property are disclosed. Smart thermostat hubs may bi-directionally communicate with the management platform using a LoRaWAN communication link and communicate with smart devices present within an apartment of the multi-family residential property via a non-LoRaWAN communication link. Smart thermostat hub may provide a gateway or bridge between the management platform and an offline door lock, thereby enabling access credentials for an offline door lock to be disabled from the management platform, and may serve to facilitate remote configuration of other smart devices, such as thermostats and smart light fixtures, for example.
