Abstract

A device for handing off a wireless connection can include a receiver configured to receive a communication signal from a wireless device within a first wireless cell, a first processor configured to determine communication information regarding the first wireless cell, and a storage unit configured to store directional information regarding the first wireless cell. In addition, the device can have a transmitter configured to transmit the directional information to a wireless device located within the first wireless cell, and a second processor configured to provide wireless connection to the wireless device through the receiver and the transmitter. The second processor can Handoff the wireless connection to a second wireless cell.

Claims (44)

1. A method of handing off a wireless connection, said method comprising the steps of:

establishing a wireless connection with a wireless device within a first wireless cell;

determining communication information with regard to the first wireless cell, determining communication information comprising determining a signal coverage area for the first wireless cell;

providing wireless connection to the wireless device within the first wireless cell;

transmitting directional information to the wireless device based upon historical pathways; and

handing off the wireless connection to a second wireless cell;

wherein the step of transmitting directional information comprises transmitting the directional information via wireless communication standards comprising at least one of a short range communication method, a low cost short-range wireless specification, and an Ultra Wide Band (UWB) communication standard.

2. The method of claim 1 , wherein the step of determining communication information comprises the step of:

determining location information of the wireless device.

3. The method of claim 2 , wherein the step of determining communication information comprises the step of:

determining signal propagation information with regard to the first wireless cell.

4. The method of claim 1 , wherein the step of transmitting directional information comprises the step of:

transmitting directional information based on stored historical pathways.

5. A device for handing off a wireless connection, said device comprising:

a receiver configured to receive a communication signal from a wireless device within a first wireless cell;

a first processor configured to determine communication information regarding the first wireless cell;

a storage unit configured to store directional information regarding the first wireless cell;

a transmitter configured to transmit the directional information to a wireless device located within the first wireless cell;

a second processor configured to provide wireless connection to the wireless device through the receiver and the transmitter,

wherein the second processor hands off the wireless connection to a second wireless cell; and

wherein the transmitter is configured to transmit the directional information via short range wireless communication methods standards comprising at least one of a short range communication standard, a low cost short-range wireless specification, and an Ultra Wide Band (UWB) communication standard.

6. The device of claim 5 , wherein the first processor is configured to determine location information of the wireless device.

7. The device of claim 6 , wherein the first processor is configured to determine signal propagation information with regard to the first wireless cell.

8. The device of claim 7 , wherein the first processor is configured to determine signal coverage information with regard to the first wireless cell.

9. The device of claim 5 , wherein the storage unit is configured to store the directional information based on historical pathways.

10. The device of claim 5 , wherein the second processor hands off the wireless connection to the second wireless cell when the wireless device is within the second wireless cell.

11. A system for handing off a wireless connection, said system comprises:

an establishing means for establishing a wireless connection with a wireless device within a first wireless cell;

a determining means for determining communication information with regard to the first wireless cell, the communication information comprising a signal coverage area of the first wireless cell;

a providing means for providing wireless connection to the wireless device within the first wireless cell;

a transmitting means for transmitting directional information to the wireless device; and

a hand-off means for handing off the wireless connection to a second wireless cell;

wherein the transmitter means is configured to transmit the directional information via short range wireless communication methods, a low cost short-range wireless specification, and an Ultra Wide Band (UWB) communication standard.

12. The system of claim 11 , wherein the determining means determines location information of the wireless device.

13. The system of claim 12 , wherein the determining means determines signal propagation information with regard to the first wireless cell.

14. The system of claim 11 , wherein the transmitting means transmits directional information based on stored historical pathways.

15. The system of claim 11 , wherein the hand-off means hands off the wireless connection when the wireless device is within the second wireless cell.

16. A method of handing off a wireless connection, said method comprising the steps of:

establishing a wireless connection with a wireless device within a first wireless cell;

determining communication information with regard to the first wireless cell;

providing wireless connection to the wireless device within the first wireless cell;

transmitting directional information to the wireless device based upon historical pathways; and

handing off the wireless connection to a second wireless cell;

wherein the step of transmitting directional information comprises transmitting the directional information via wireless communication standards comprising at least one of a short range communication method, a low cost short-range wireless specification, and an Ultra Wide Band (UWB) communication standard.
