Abstract

Configurations are described for maintaining a continuity and quality of wireless signal connection between a mobile device and systems accessible through the internet. In particular, configurations are disclosed to address the challenge of a mobile device that moves through a physical environment wherein the best wireless connectivity performance is achieved by switching between available connection sources and constantly evaluating a primary connection with other available connections that may be switched in to become a new primary connection. The mobile device may be self-propelled or carried by some other mobilizing means.

Claims

1. A computerized system comprising:

a mobile controller;

a remote controller;

first and second wireless adaptors operatively coupled to the mobile controller and configured to operate independently such that;

a. one is scanning for a connection between the mobile controller and the remote controller while the other retains a connection between the mobile controller and the remote controller;

b. they operate to automatically;

a. scan to find available wireless access points;

b. connect to the remote controller through a first wireless access point with the first wireless adaptor and evaluate the connectivity of the connection;

c. while retaining connectivity with the remote controller through the first wireless adaptor, connect to the remote controller through a second wireless access point with the second wireless adaptor and evaluate the connectivity of the connection;

d. compare the evaluated connectivities of the first and second wireless adaptors to find a highest evaluated connection and a lowest evaluated connection; and

e. maintain connectivity between the mobile controller and remote controller through the highest evaluated connection,

wherein the mobile controller is configured to evaluate the connectivity of the connection with first or second channel based at least in part upon a factor selected from the group consisting of;

latency, packet loss, and financial cost of connectivity.

2. The system of claim 1, wherein each of the first and second wireless adaptors has a single wireless transmitter.

3. The system of claim 2, wherein the single wireless transmitter is an RF antenna.

4. The system of claim 2, wherein in a background scanning mode, data is alternated through one of the single wireless transmitter from both a first channel and a second channel.

5. The system of claim 1, wherein at least one of the first and second wireless adaptors is compatible with an IEEE 802.11 standard selected from the group consisting of:

802.11A, 802.11B, 802.11G, and 802.11N.

6. The system of claim 1, wherein at least one of the first and second wireless adaptors is a cellular telephone adaptor.

7. The system of claim 1, wherein at least one of the first and second wireless adaptors is an IEEE 802.16 compatible adaptor.

8. The system of claim 1, wherein at least one of the first and second wireless adaptors is a free-space optical adaptor.

9. The system of claim 1, wherein the mobile controller is configured to operate at least one of the first and the second wireless adaptors to scan using a discrete frequency band.

10. The system of claim 9, wherein the discrete frequency band is selected based upon a determined prevalence of active wireless access points.

11. The system of claim 1, wherein the mobile controller is configured to scan again to find available wireless access points after disconnecting connectivity between the mobile controller and remote controller through the lowest evaluated connection.

12. The system of claim 1, wherein the mobile controller is configured to repeatedly cycle between scanning to find available wireless access points and disconnecting connectivity between the mobile controller and remote controller through the lowest evaluated connection.

13. The system of claim 12, wherein the mobile controller is configured to repeatedly cycle at a frequency between about 100 cycles/second and about ½

cycles/second.

14. The system of claim 1, wherein the mobile controller is coupled to a motorized vehicle.

15. The system of claim 14, wherein the motorized vehicle comprises a robot.

16. The system of claim 1, further comprising a third wireless adaptor operatively coupled to the mobile controller and configured to operate independently of the first and second wireless adaptors.

17. The system of claim 16, wherein the mobile controller is configured to connect to the remote controller through all three wireless adaptors via different wireless access points, evaluate connectivity through each, and maintain connectivity only through the highest evaluated connection.

18. The system of claim 17, wherein the first and second wireless adaptors are compatible with an IEEE 802.11 standard selected from the group consisting of:

802.11A, 802.11B, 802.11G, and 802.11N.

19. The system of claim 18, wherein the third wireless adaptor is a cellular telephone adaptor.

20. The system of claim 1, further comprising operating at least one of the first and second wireless adaptors to automatically disconnect connectivity between the mobile controller and remote controller through the lowest evaluated connection.
