Abstract

A protocol and methodology that extends the battery power in a remote asset tracking device by storing location data more than once (i.e., “n” times), yet transmitting that data only once to a server. In other words, multiple data points are transmitted simultaneously. Devices and systems incorporating the protocol are also provided.

Claims

1. A data protocol for a wireless device, the protocol comprising:

determining a first location of a device and saving the determined first location of the device;

determining a second location of the device subsequent to the first location and saving the determined second location of the device;

transmitting the first location and the second location to a server;

mapping the second location;

after mapping the second location, mapping the first location; and

reporting the mapped second location and the mapped first location.

2. The protocol of claim 1 further comprising:

determining a third location of the a device subsequent to the second location and saving the determined third location of the device; and

transmitting the third location to a server;

mapping the third location before mapping the second location; and

reporting the mapped third location.

3. A data protocol for a wireless device, the protocol comprising:

sequentially determining “

n”

number of locations of a device and saving the “

n”

number of locations of the device, where “

n”

is two or greater;

transmitting the “

n”

number of locations to a server;

reverse mapping the “

n”

number of locations; and

reporting the mapped locations.

4. The protocol of claim 3 wherein “

n”

is three.

5. The protocol of claim 3 wherein “

n”

is four.

6. The protocol of claim 3 wherein “

n”

is two.

7. An asset tracking system comprising:

a wireless tracking device comprising a GPS/GLONASS system, an RF communication module or a cellular communication module configured to transmit information to a remote server, non-volatile memory, and a control system comprising a data protocol; and

an asset intelligence (AI) server;

the protocol configured to determine “

n”

locations of the device and store those “

n”

locations in the memory, and transmit the stored “

n”

locations to the AI server as a batch.

8. The asset tracking system of claim 7 wherein the AI server is configured to reverse map the “

n”

locations.

9. The asset tracking system of claim 7 further comprising a display to report the “

n”

locations.
