Mobile data flow collection and dissemination
First Claim
1. In a mobile communications environment, a method comprising:
- transmitting data from a short-range radio device in a mobile vehicle to an external receiver that is not physically connected to the mobile vehicle, including by boosting transmission power of the device to a maximum transmission power or substantially close to the maximum transmission power as allowed by governmental regulations at least while transmitting to the external receiver, wherein the boosting includes using at least one of additional circuitry associated with the device or an amplifier associated with the mobile vehicle, and wherein transmitting the data comprises;
advertising to establish a link with the external receiver;
broadcasting current data of the mobile vehicle associated with the short-range radio and any stored data received from other mobile vehicles; and
transitioning to a receive data mode.

Abstract
Described is a technology in which Bluetooth® devices, e.g., navigation devices, are enhanced with additional power amplification to allow long range radio communication links between moving vehicles and/or between moving vehicles and roadside hubs. In one example, collection and dissemination of traffic information, including aggregation and filtering, is facilitated via a Bluetooth® vehicle-to-vehicle and/or vehicle-to-roadside hub ad-hoc network. Also described is efficient connection establishment and data transfer for vehicle to vehicle and vehicle-to-roadside hubs via the enhanced Bluetooth® radio. The ad-hoc network comprising a mesh of vehicles/a supernode also facilitates the exchange of information that originated at an Internet source.

10. In a mobile communications environment, a system comprising:
a mobile Bluetooth®
-enabled device in a vehicle, the device configured to transmit data to at least one of another vehicle or a roadside hub at an increased output power level relative to recommended Bluetooth®
power levels to allow long range radio communication links between the vehicle and the at least one of the other vehicle or the roadside hub, the increased output power level being a maximum transmission power or substantially close to the maximum transmission power as allowed by governmental regulations, wherein the device is configured to transmit the data at the increased output power level using at least one of additional circuitry associated with the device or an amplifier associated with the vehicle, the data including information that is useable in determining traffic conditions.- View Dependent Claims (11, 12, 13, 14, 15)

16. In a mobile communications environment, a method executed at least in part on at least one processor, the method comprising:
transmitting first data from a Bluetooth®
device in a mobile vehicle to an external receiver, the first data comprising Bluetooth®
discovery data, and including information that is useable in determining traffic conditions within the Bluetooth®
discovery data, the first data transmitted at a boosted power level using at least one of additional circuitry associated with the device or an amplifier associated with the mobile vehicle, wherein transmitting the first data comprises;advertising to establish a link with the external receiver; broadcasting current data of the mobile vehicle associated with the Bluetooth®
device and any stored data received from other mobile vehicles;transitioning to a receive data mode; and receiving second data from at least one other Bluetooth®
device that is not physically connected to the mobile vehicle, and using the first and second data to estimate upcoming traffic conditions.- View Dependent Claims (17, 18, 19, 20)
