Abstract

Systems and methods to exchange data between a vehicle and a remote computer system, are disclosed. In one embodiment, a system to exchange data between a vehicle and a remote computer system comprises at least one power line adapted to couple to the vehicle, a local area network, a modem coupled to the local area network and the at least one power line, and a power line interference server comprising logic to allocate communication channels within a specified frequency range on the power line. Other embodiments may be described.

First claim

What is claimed is:

1. A system comprising:
a modem coupled to a power line, the power line adapted to couple a vehicle with a remote computer via a communication network; and
a power line interference server,
wherein the power line interference server is configured to dynamically determine whether a first set of portions of a specified frequency range are unavailable for communication channels,
wherein the power line interference server is configured to determine a throughput available on a first portion of the first set of portions and to add a frequency range corresponding to the first portion of the first set of portions to frequency data from a database in response to the throughput not satisfying a throughput threshold,
wherein the power line interference server is configured to cease dynamically determining whether the first portion is unavailable for communication channels in response to the throughput not satisfying the throughput threshold, and
wherein the power line interference server comprises logic to allocate communication channels within a specified frequency range on the power line for the vehicle to communicate with the remote computer within the specified frequency range after the power line interference server ceases to dynamically determine whether the first portion is unavailable for communication channels.

2. The system of claim 1 ,
wherein the power line interference server is configured to determine an ambient noise level on a second portion of the first set of portions, and
wherein the power line interference server is configured to allocate a first communication channel of the communication channels within the second portion in response to the ambient noise level satisfying a threshold noise level.

3. The system of claim 1 , wherein the power line interference server is configured to determine a second set of portions of the specified frequency range that is unavailable for communication channels based on the frequency data, and wherein the first set of portions is distinct from the second set of portions.

4. The system of claim 3 ,
wherein the database includes location specific information identifying a plurality of frequency regulations corresponding to a plurality of locations.

5. The system of claim 4 ,
wherein a first frequency regulation of the plurality of frequency regulations indicates that a first particular frequency range is unavailable for communication channels at a first location of the plurality of locations,
wherein a second frequency regulation of the plurality of frequency regulations indicates that a second particular frequency range is unavailable for communication channels at a second location of the plurality of locations,
wherein the first frequency range is different from the second frequency range, and
wherein the first location is distinct from the second location.

6. The system of claim 3 , wherein the second set of portions includes a particular frequency range used for communication by an aviation application.

7. The system of claim 1 , wherein the specified frequency range extends from 1.7 MHz to 80 MHz.

8. A method comprising:
dynamically determining, at a power line interference server, whether a first set of portions of a specified frequency range on a power line, which couples a modem to a vehicle for the vehicle to communicate with a remote computer system via a communication network, are unavailable for a communication channel;
determining a throughput available on a first portion of the first set of portions, wherein the power line interference server ceases to dynamically determine whether the first portion is unavailable for the communication channel in response to the throughput not satisfying a throughput threshold;
adding a frequency range corresponding to the first portion of the first set of portions to frequency data from a database in response to the throughput not satisfying the throughput threshold;
allocating the communication channel within a second portion of the first set of portions after ceasing to dynamically determine whether the first set of portions is unavailable for the communication channel, wherein the second portion is dynamically determined to be available for the communication channel; and
exchanging data between the vehicle and the remote computer system on the allocated communication channel.

9. The method of claim 8 , wherein the specified frequency range extends from 1.7 MHz to 80 MHz.

10. The method of claim 8 , further comprising:
determining a vehicle location of the vehicle; and
determining a second set of portions of the specified frequency range that is unavailable for the communication channel based on the vehicle location.

11. The method of claim 8 , further comprising determining an ambient noise level on a third portion of the first set of portions, wherein the communication channel is allocated within the third portion in response to the ambient noise level satisfying a threshold noise level.

12. The method of claim 8 , further comprising determining a second set of portions of the specified frequency range that is statically unavailable for the communication channel based on the frequency data, wherein the first set of portions is distinct from the second set of portions.

13. The method of claim 12 , wherein the second set of portions includes a particular frequency range used for communication by an aviation application.

14. The method of claim 8 , further comprising:
detecting one or more radio communication services transmitting at one or more frequencies in the specified frequency range; and
transmitting a signal to the modem to block transmission over the power line at the one or more frequencies in the specified frequency range.

15. The method of claim 8 , further comprising blocking frequency ranges unavailable for the communication channel by static notching or dynamic notching.

16. A non-transitory computer readable medium storing instructions which, when executed by a processor, cause the processor to perform operations comprising:
dynamically determining, at a power line interference server, whether a first set of portions of a specified frequency range on a power line, which couples a modern to a vehicle for the vehicle to communicate with a remote computer system via a communication network, are unavailable for a communication channel;
determining a throughput available on a first portion of the first set of portions, wherein the power line interference server ceases to dynamically determine whether the first portion is unavailable for the communication channel in response to the throughput not satisfying a throughput threshold;
adding a frequency range corresponding to the first portion of the first set of portions to frequency data in response to the throughput not satisfying the throughput threshold;
after ceasing to dynamically determine whether the first set of portions is unavailable for the communication channel, allocating the communication channel within a second portion of the first set of portions, wherein the second portion is dynamically determined to be available for the communication channel; and
exchanging data between the vehicle and the remote computer system on the allocated communication channel.

17. The non-transitory computer readable medium of claim 16 , wherein the communication channel is allocated in response to determining that the vehicle is located at a facility that provides a broadband over power line connection, and wherein the operations further comprise, in response to determining that the fa
