Problems solved by technology

However, this location determination is too imprecise for determining the position of the terminal in a space which, for example, just includes the passenger compartment.
Furthermore, electromagnetic waves are only transmitted in an attenuated and / or distorted manner in closed spaces and this can adversely affect positioning within said spaces

Abstract

The invention relates to a device, a method and a computer program for characterizing antenna elements in a space. Embodiments create an apparatus, method and computer program for characterizing a plurality of antenna elements within a predefined space. The antenna unit is designed to supply the mobile transceiver with radio service in the space. The antenna unit can be operated in two operating modes, transmit and receive. At least one first antenna element has a plurality of radiation characteristics. The method includes operating the first antenna unit in a first operating mode and operating the second antenna unit in a second operating mode. The method furthermore includes changing the radiation characteristic of the first antenna unit and detecting information about the transmission characteristic for the radiation characteristic between the first antenna unit and the second antenna unit. The method also includes characterizing the antenna unit on the basis of the information about the transmission properties.

Description

technical field [0001] The present invention relates to a device, a method and a computer program for characterizing an antenna unit within a predefined space, in particular but not exclusively to the characterization of a plurality of antenna units in a vehicle interior space. Background technique [0002] Mobile devices (also referred to hereinafter as mobile devices) are also increasingly used in enclosed spaces (also referred to in English as indoor areas). For example, in vehicles (Fahrzeug), mobile devices are used for communication, passenger entertainment, forwarding relevant information about the status of the vehicle or about the traffic situation on the planned route, etc., where the vehicle is for example Cars, trains, planes, buses, ships and more. In this case, it may be useful to distribute the information in the space in a targeted manner, for example depending on the position of the mobile device in the space, for example in the passenger compartment. For ...
