Security system and method for wireless communication within a vehicle
First Claim
1. A method for providing wireless communications between nodes of a vehicle, the method comprising the steps of:
- providing a plurality of frequency channels on which a plurality of nodes of a first vehicle may wirelessly communicate; and
the first vehicle wirelessly communicates with a second vehicle adjacent to the first vehicle, the communicating including assigning;
a first frequency channel of the frequency channels to the first vehicle for intra-vehicle transmissions within the first vehicle; and
a second frequency channel of the frequency channels to the second vehicle for intra-vehicle transmissions within the second vehicle such that the first vehicle is prohibited from using the second frequency channel and the second vehicle is prohibited from using the first frequency channel;
a first power level to the first vehicle for intra-vehicle transmissions within the first vehicle; and
a second power level to the second vehicle for intra-vehicle transmissions within the second vehicle.

Abstract
A method for providing wireless communications between nodes of a vehicle includes providing a plurality of frequency channels on which the nodes of a first vehicle may wirelessly communicate. Wireless communication with a second vehicle adjacent to the first vehicle includes assigning a first of the frequency channels to the first vehicle for intra-vehicle transmissions within the first vehicle, and a second of the frequency channels to the second vehicle for intra-vehicle transmissions within the second vehicle. The first vehicle is prohibited from using the second frequency channel and the second vehicle is prohibited from using the first frequency channel.

7. A method for providing wireless communications between nodes of a vehicle, the method comprising the steps of:
-
conducting wireless communication between a first vehicle and a second vehicle, the second vehicle being adjacent to the first vehicle; determining whether two different frequency channels are available for intra-vehicle transmissions within the first vehicle and within the second vehicle, wherein; if it is determined that two different frequency channels are available for intra-vehicle transmissions within the first vehicle and within the second vehicle, then the method comprising the further step of assigning; a first frequency channel of the frequency channels to the first vehicle for intra-vehicle transmissions within the first vehicle; and a second frequency channel of the frequency channels to the second vehicle for intra-vehicle transmissions within the second vehicle such that the first vehicle is prohibited from using the second frequency channel and the second vehicle is prohibited from using the first frequency channel, else, if it is determined that only one frequency channel is available for both intra-vehicle transmissions within the first vehicle and intra-vehicle transmissions within the second vehicle, then the method comprising the further step of assigning a time-share schedule to the first vehicle for use of the one frequency channel for intra-vehicle transmissions within the first vehicle and to the second vehicle for use of the one frequency channel for intra-vehicle transmissions within the second vehicle. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method for providing wireless communications between nodes of a vehicle, the method comprising the steps of:
-
providing a plurality of frequency channels on which a plurality of nodes of a first vehicle may wirelessly communicate; and the first vehicle wirelessly communicates with a second vehicle adjacent to the first vehicle and with a third vehicle adjacent to the second vehicle and nonadjacent to the first vehicle, the communicating including assigning; a first frequency channel of the frequency channels to;
the first vehicle for intra-vehicle transmissions within the first vehicle; and
the third vehicle for intra-vehicle transmissions within the third vehicle;a second frequency channel of the frequency channels to the second vehicle for intra-vehicle transmissions within the second vehicle such that the first and third vehicles are prohibited from using the second frequency channel and the second vehicle is prohibited from using the first frequency channel; a first maximum power level to the first vehicle for intra-vehicle transmissions on the first frequency channel within the first vehicle; and a second maximum power level to the third vehicle for intra-vehicle transmissions on the first frequency channel within the third vehicle. - View Dependent Claims (15, 16, 17, 18, 19)
