Embodiment Construction

[0116] This section consists of the following topics:

[0117] I. Terminology

[0118] II. Distance Estimation

[0119] A. Example of Angle of Departure (AoD) Estimation

[0120] B. Example of Angle of Arrival (AoA) Estimation

[0121] I. Terminology

[0122] The term "angle of departure (AoD)" as used herein is relative to an antenna array disposed with a normal axis. For a linear antenna array along a linear axis, the normal axis perpendicular to the linear axis defines a plane with the linear antenna array. From a remote receiving device occupying a plane, the visible direction of the signal emission of the linear antenna array can be represented by a viewing vector. The angle between the viewing vector and the normal axis is defined as the angle of departure (AoD) of the signal as it leaves the antenna array. In an embodiment, the antenna array may be arranged as a two-dimensional array in a plane, and the normal axis is perpendicular to the plane of the antenna ar...

Abstract

Method, apparatus, and computer program product example embodiments provide secure distance estimation based on direction measurement. According to an example embodiment of the invention, a method comprises receiving, by an apparatus (102) from a remote device (100), one or more wireless packets including information packets containing angle of departure information (160) of the remote device (100); determining in the apparatus (102), a first angle of departure and a second angle of departure from the received angle of departure information; and generating distance estimation data in the apparatus relative to the remote device (100), based on the determined first angle of departure and second angle of departure.

Description

[0001] Inventors: Kimmo KALLIOLA, Antti KAINULAINEN, Ville RA KI and Fabio BELLONI technical field [0002] The technical field of the present invention relates to wireless short-distance communication, and more particularly relates to safe distance measurement. Background technique [0003] Modern society has adopted, and increasingly relies on, wireless communications for a variety of purposes, such as connecting users of wireless communications devices with other users. Wireless communication devices range from battery-operated handheld devices to stationary household and / or commercial devices that use the mains power supply. Due to the rapid development of wireless communication devices, many fields that can realize new types of wireless communication applications have arisen as the times require. [0004] Cellular networks facilitate communications over large geographic areas. These network technologies are often divided by generation, from the first generation (1G) o...
