Abstract
Examples disclosed herein relate to illustrate an in-vehicle communication system having wireless extension devices, such as an active repeater or an edge reflectarray device. The wireless extension devices operate in coordination to redirect signals within a vehicle.
Claims20
An in-vehicle communication system, comprising:
- a plurality of wireless extension devices positioned around a perimeter of a vehicle, the plurality of wireless extension devices adapted to communicate with a wireless network and redirect signals within a vehicle;
- an internal reflectarray configured to redirect the signals from at least one of the plurality of wireless extension devices to a location within the vehicle,
- wherein the internal reflectarray is a passive device, and the at least one of the plurality of wireless extension devices comprises:
- a receive antenna,
- a transmit antenna, and
- an active relay coupled to the receive antenna and the transmit antenna;
- and
- an in-vehicle control (IVC) unit adapted to receive the signals from the plurality of wireless extension devices, the IVC unit comprising:
- a signal detection module;
- and
- a processing unit.
8 more elements
A wireless extension system, comprising:
- an in-vehicle control (IVC) unit;
- at least one edge repeater controlled by the IVC unit and operates to amplify and redirect received signals, wherein the at least one edge repeater comprises a receive antenna, a transmit antenna, and an active relay coupled to the receive antenna and the transmit antenna;
- and
- a passive reflectarray positioned to receive redirected signals from the at least one edge repeater, wherein the passive reflectarray is a meta-structure (MTS) device comprising a plurality of different sized MTS elements.
1 more element
A wireless extension system, comprising:
- an in-vehicle control (IVC) unit positioned in a vehicle;
- an edge repeater positioned on a perimeter of the vehicle, wherein the edge repeater is controlled by the IVC unit and configured to amplify and redirect received signals;
- and
- a passive reflectarray positioned to receive redirected signals from the edge repeater, wherein the passive reflectarray is a meta-structure (MTS) device, and wherein the IVC unit comprises:
- a signal detection unit adapted to detect low amplitude wireless signals from a base station;
- and
- a processing unit responsive to detection of signals below a threshold.
