Abstract

A broadband wireless network includes intelligent base stations and mobile units. The network includes control means to manage connectivity of the mobile units to the intelligent base stations. Software is provided to control connection of the mobile unit to an intelligent base station having preferred signal characteristics. When a mobile unit connects to an intelligent base station, the software broadcasts corrected routing information to all intelligent base stations on the network allowing persistent wireless connectivity.

Claims

1. A network comprising:

at least two intelligent base stations, each intelligent base station having a unique ESSID and a unique MAC address;

at least one mobile device adapted to communicate with said intelligent base stations, each mobile device having a unique MAC address; and

means for controlling the communications between said intelligent base stations and said mobile devices, wherein said means for controlling communications between said intelligent base stations and said mobile devices comprises;

means for transmitting routing information including a MAC address from said mobile device to said intelligent base station, and

means for transmitting routing information from any one of said at least one intelligent base station to each other said at least one intelligent base station on the network,

wherein said means for controlling communications between said intelligent base stations and said mobile devices includes software for performing the following steps;

determining the signal strength of a signal from each intelligent base station in the network at a mobile device and identifying the intelligent base station having the strongest signal at the mobile device;

determining the saturation of the signal of each intelligent base station in communication with said mobile device;

determining the preferred connection between said mobile device and one of said intelligent base stations based on the signal strength of the signal from the intelligent base station and the saturation of the intelligent base station;

updating the address resolution protocol cache and broadcasting the routing information to each intelligent base station in the network;

scanning available signals from intelligent base stations within the network to determine whether the signal strength and saturation of the signals from a different intelligent base station have changed to make the second intelligent base station the preferred connection;

connecting to the second intelligent base station; and

updating the address resolution protocol cache and IP broadcasting the routing information to each intelligent base station on the network.

2. A network according to claim 1 wherein said mobile device is a server for a subnetwork.

3. A network according to claim 1 where said at least one mobile device includes a computer.

4. A network according to claim 1 where said at least one mobile device includes a cellular telephone.

5. A network according to claim 1 further comprising a plurality of mobile devices.

6. A network according to claim 1 further comprising a plurality of intelligent base stations.

7. A computer network according to claim 1 wherein said mobile devices further comprise:

means for determining the signal strength of a signal from said at least one intelligent base station, and

means for comparing the signal strength of a signal from said at least one intelligent base station.

8. A network according to claim 1 wherein said means for transmitting routing information from said mobile device to said intelligent base station includes the step of communicating the MAC of the mobile device to the intelligent base station.

9. A method for controlling a wireless network comprising:

determining a signal strength of a signal from each intelligent base station in the wireless network at a mobile device;

identifying the intelligent base station having the strongest signal at the mobile device;

determining a saturation of the signal of each intelligent base station in communication with the mobile device;

determining a preferred connection between the mobile device and one of the intelligent base stations based upon a signal strength of the signal from the intelligent base station and a saturation of the intelligent base station;

updating an address resolution protocol cache;

broadcasting routing information to each intelligent base station in the network;

scanning available signals from intelligent base stations within the network to determine whether a signal strength and a saturation of signals from a different intelligent base station have changed to make the second intelligent base station the preferred connection;

connecting to the second intelligent base station;

updating an address resolution protocol cache; and

IP broadcasting the routing information to each intelligent base station on the network.

10. A method for controlling a wireless network which includes one or more intelligent base stations and one or more mobile devices, the method comprising:

establishing a connection between a first one of the one or more mobile devices and a first one of the one or more intelligent base stations wherein the connection is established based upon a signal strength of a signal between the first one of the one or more intelligent base stations and the first one of the one or more mobile devices and the saturation of the first one of the one or more intelligent base stations compared with a saturation of other ones of the one or more intelligent base stations;

updating an address resolution protocol cache; and

broadcasting routing information to each intelligent base station in the network;

monitoring signal strength and a saturation of the one or more intelligent base stations to determine a change in signal strength and saturation of any of the one or more intelligent base stations with respect to the first one of the one or more mobile devices;

in response to a signal strength and saturation of a second, different intelligent base station changing, establishing a connection between the first mobile device and the second, different intelligent base station;

updating the address resolution protocol cache; and

broadcasting the routing information to each intelligent base station in the network.

11. The method of claim 10 wherein broadcasting the routing information to each intelligent base station on the network comprises IP broadcasting the routing information to each intelligent base station on the network.

12. The method of claim 10 wherein establishing a connection comprises:

determining a signal strength of a signal from each of the one or more intelligent base stations in the wireless network to a first one of the one or more mobile devices;

identifying an intelligent base station having the strongest signal at the first one of the one or more mobile devices; and

determining a saturation level of a signal from each intelligent base station in communication with the first one of the one or more mobile devices.

13. The method of claim 12 wherein determining whether a signal strength and saturation of signals from each of the one or more intelligent base station have changed comprises evaluating available signals from the one or more intelligent base stations within the network.

14. The method of claim 13 wherein evaluating available signals from the one or more intelligent base stations within the network includes scanning available signals from the one or more intelligent base stations within the network.

15. The method of claim 12 wherein determining a signal strength of a signal from each of the one or more intelligent base stations in the wireless network comprises determining, in at least one of the one or more mobile devices, a signal strength of a signal from each of the one or more intelligent base stations in the wireless network.

16. The method of claim 12 wherein identifying an intelligent base station having the strongest signal comprises, identifying, at each of the one or more mobile devices, an intelligent base station having the strongest signal.
