Embodiment Construction

[0062] figure 1 A passive repeater 100 according to the invention for repeating radio signals and its use in a housing is shown. A first device 1 with a radio interface represented here by an antenna 2 is located in a housing 3 , which forms an interior space 110 . A second device 10 with a radio interface represented by an antenna 9 is arranged outside the housing 3 , ie in an external space 120 . A passive repeater 100 for repeating radio signals has a first antenna 5 which is arranged in an interior space 110 and a second antenna 6 which is arranged in an exterior space 120 . The first antenna and the second antenna are connected to one another via a passive galvanic coupling 13 which passes through the opening 7 in the housing wall. The first antenna 5 may be introduced into the inner space 110 from the outer space 120 through the opening 7 , and the second antenna 6 may be drawn out from the inner space 110 into the outer space 120 through the opening 7 .

Abstract

The invention relates to a passive repeater for forwarding radio signals from a first device having a radio interface to a second device having a radio interface, wherein the passive repeater is configured to forward radio signals between an interior of a housing, which has a housing wall acting as a radio barrier, and an exterior, through the housing wall, wherein the passive repeater has a first antenna and a second antenna for this purpose, which are connected to each other by means of passive and galvanic coupling, and wherein the first antenna can be arranged in the interior and the second antenna can be arranged in the exterior, and the passive coupling can be carried out through an opening in the housing wall, and wherein the first antenna can be inserted into the interior from the exterior through the opening and / or the second antenna can be withdrawn from the interior to the exterior through the opening. The invention further relates to a radio system having such a passive repeater, to a vehicle having such a repeater or such a radio system, to a store having such a repeater or such a radio system, and to a use of such a repeater or such a radio system.

Description

technical field [0001] The invention relates to a passive repeater for retransmitting radio signals from a first device having a radio interface to a second device from an interior space to an exterior space, the second device having a radio interface, the external Spaces are separated by radio barriers. Furthermore, the invention relates to a radio system with such a passive repeater, a vehicle with such a repeater or such a radio system, a support with such a repeater or such a radio system components, and an application of such a repeater or such a radio system. Background technique [0002] It is known from the prior art to overcome radio barriers by extending the antenna of the first device by means of a cable extension in such a way that it can be arranged beyond a radio barrier (for example a shielded housing). Furthermore, active Bluetooth or WLAN repeaters are known, some of which also have an intermediate network, which however are not suitable for many applicati...
