Disclosed is a method to optimize the transmission of data to and from a moving vehicle by combining a plurality of data packets into larger packets designed for parallel transmission during the brief period that the vehicle passes a stationary transmitter/receiver.

System to transfer data at points along a predicted path

Mobile devices are now common and demand internet connectivity. Internet connectivity is achieved through cell-phone networks and or wi-fi, but coverage of both systems is incomplete. In fact there are large areas without any cell or wi-fi coverage.

When people are travelling through these areas (typically in a car or train) it

would be advantageous to be able to send and receive internet data (TCP/IP packets).

    This solution disclosed provides a method to collect internet requests in 'chunks', relay them to the internet, collect the responses and build a new 'chunk' containing multiple responses and then unpack that into the individual responses. By placing all the data into larger 'chunks', rapid transmission is enabled.

    The solution consists of 3 parts, a device in the vehicle, a series of devices along the road and a central controller of the roadside devices.

    The device in the car provides a wi-fi hotspot in the usual manner. It relays data to the roadside devices in a very fast manner when a roadside device is passed.

    The roadside devices relay the data to the central system which sends the internet request out, collects the responses and sends the data to the next roadside device that the car will pass so that it can be relayed to the car. The device in the car then receives the data and translates it back into internet responses for the devices on its wi-fi network.

    The core of this disclosure is the manner in which the car device and roadside devices package the data into an efficient form that is suited for very rapid and short transmission.

    Figure 1 shows a vehicle containing a gateway device 500. This device is capable of the following:

    1.) providing a local wifi signal within the car to which one or more devices (200, 201, 202) can be connected, using the known art of wifi connectivity.

    2.) collecting all internet data requests from the connected devices and holding them in a buffer as shown in figure 2.

    3.) Rapidly exchanging the buffer of data with a roadside device 100 using radio signals as shown in figure 3. The rapid data exchange may be occomplished through the use of multiple transmitt...
