Abstract
Exemplary embodiments are disclosed of vehicular adaptive distributed antenna systems (V-ADAS) or distributed antenna farms. In exemplary embodiments, the system may include antennas that are sharable with one or more software defined radio (SDR) instances. In exemplary embodiments, the system may be configured to be operable for dynamic selection of the best antenna(s) for the specific situation, e.g., for high reliability communication and/or power and performance optimization, rural versus urban, shadowing effects of the vehicle itself and/or nearby obstructions, etc. In exemplary embodiments, the system may be configured to power down one or more of the remote active antennas that are not needed.
Claims25
A computing system for controlling and managing operation of a plurality of antennas distributed in a vehicle, the computing system comprising multiple software defined radio instances configured for communication with the plurality of antennas, wherein:
- the computing system is configured such that the plurality of antennas are connected with the multiple software defined radio instances;
- and
- the computing system is configured to be operable for selecting one or more in-phase quadrature (IQ) data streams to be routed from the plurality of antennas to at least one of the multiple software defined radio instances based on a priority of each of the multiple software defined radio instances, wherein at least two software defined radio instances of the multiple software defined radio instances share a same subscriber identification module (SIM) thereby enabling an increased data rate.
A method for controlling and managing operation of a plurality of antennas distributed in a vehicle that also includes multiple software defined radio instances configured for communication with the plurality of antennas, the method comprising:
- linking the plurality of antennas with the software defined radio instances;
- selecting one or more in-phase quadrature (IQ) data streams to be routed from the plurality of antennas to at least one of the multiple software defined radio instances based on a priority of each of the multiple software defined radio instances, wherein at least two software defined radio instances of the multiple software defined radio instances share a same subscriber identification module (SIM) thereby enabling an increased data rate.
