Abstract

A communication system and method are described. In one embodiment, the method comprises a switch receiving information from at least one repeater for each packet received without errors by the at least one repeater, the switch, in response to the information, determining an amount of wireless communication activity each of the at least one repeater is experiencing, the switch determining whether to cause one or more repeaters to change status regarding wireless reception and transmission of packets from other devices in the network based on repeater location and repeater density and the information received from the at least one repeater, and the switch causing a change in the status for at least one of the one or more repeaters by signaling to the at least one of the one or more repeaters.

Claims

1. A method for configuring a wireless communication network, comprising:

(A) determining an amount of wireless communication activity a repeater from among a plurality of repeaters is experiencing based on received data packets and information associated with the received data packets;

(B) determining a location and a density of the plurality of repeaters based upon the amount of wireless communication activity;

(C) determining whether to cause the repeater to change its configuration based on the location and the density of the plurality of repeaters; and

(D) causing the change in the configuration by signaling a command to the repeater.

2. The method of claim 1, further comprising:

(E) receiving the received data packets and the information associated with the received data packets.

3. The method of claim 1, wherein step (A) comprises:

(A)(i) determining the amount of wireless communication activity the repeater is experiencing based on the received data packets and received signal strength information and signal-to-noise-ratio (SNR) associated with the received data packets.

4. The method of claim 1, further comprising:

(E) determining a density of a plurality of mobile stations communicatively coupled to the repeater based on the received data packets and the information associated with the received data packets.

5. The method of claim 4, further comprising:

(F) maintaining a location tracking database to maintain a number of mobile stations from among the plurality of mobile stations for which the repeater is receiving the received data packets.

6. The method of claim 4, wherein the received data packets include addresses from among a plurality of addresses assigned the mobile stations, and

wherein step (E) comprises:

(E)(i) determining a number of unique addresses from among the addresses to determine the density of mobile stations communicatively coupled to the repeater.

7. The method of claim 6, wherein step (C) comprises:

(C)(i) determining whether to cause the repeater to change its configuration based on the density of mobile stations and the location and the density of the plurality of repeaters.

8. The method of claim 4, wherein step (D) comprises:

(D)(i) causing the change in the configuration by signaling the command to the repeater over a wired connection.

9. The method of claim 1, wherein step (B) comprises:

(B)(i) determining whether to cause the repeater to change a repeater transmitter power level and a repeater receiver sensitivity based on the amount of wireless communication activity.

10. A method for configuring a wireless communication network, comprising:

(A) determining an amount of wireless communication activity a repeater from a plurality of repeaters is experiencing based on received data packets and information associated with received data packets;

(B) determining a location and a density of the plurality of repeaters based upon the amount of wireless communication activity;

(C) determining whether to cause the repeater to change from a first state to a second state based on the location and the density of the plurality of repeaters, the first state and the second state being selected from a group consisting of;

an activated state,

a deactivated state, and

a hot standby state; and

(D) causing the change from the first state to the second state by signaling a command to the repeater.

11. The method of claim 10, further comprising:

(E) receiving the received data packets and the information associated with the received data packets.

12. The method of claim 10, wherein step (A) comprises:

(A)(i) determining the amount of wireless communication activity the repeater is experiencing based on the received data packets and received signal strength information and signal-to-noise-ratio (SNR) associated with the received data packets.

13. The method of claim 10, further comprising:

(E) determining a density of a plurality of mobile stations communicatively coupled to the repeater based on the received data packets and the information associated with the received data packets.

14. The method of claim 13, further comprising:

(F) maintaining a location tracking database to maintain a number of mobile stations from among the plurality of mobile stations for which the repeater is receiving the received data packets.

15. The method of claim 13, wherein step (D) comprises:

(D)(i) causing the change from the first state to the second state by signaling the command to the repeater over a wired connection.

16. The method of claim 13, wherein the received data packets include addresses from among a plurality of addresses assigned the mobile stations, and

wherein step (E) comprises:

(E)(i) determining a number of unique addresses from among the addresses to determine the density of mobile stations communicatively coupled to the repeater.

17. The method of claim 16, wherein step (C) comprises:

(C)(i) determining whether to cause the repeater to change from the first state to the second state based on the density of mobile stations and the location and the density of the plurality of repeaters.

18. An apparatus for configuring a wireless communication network, comprising:

a switch configured to determine an amount of wireless communication activity a repeater from among a plurality of repeaters is experiencing based on received data packets and information associated with the received data packets, to determine a location and a density of the plurality of repeaters based upon the amount of wireless communication activity, and to determine whether to cause the repeater to change its configuration based on the location and the density of the plurality of repeaters.

19. The apparatus of claim 18, wherein the switch is further configured to signal a command to the repeater to cause the change in the configuration.

20. The apparatus:

of claim 18, wherein the switch is further configured to receive the received data packets and the information associated with the received data packets from the repeater.

21. The apparatus of claim 18, wherein the information associated with the received data packets comprises:

received signal strength information and signal-to-noise-ratio (SNR) associated with the received data packets.

22. The apparatus of claim 18, wherein the switch is further configured to determine a density of a plurality of mobile stations communicatively coupled to the repeater based on the received data packets and the information associated with the received data packets.

23. The apparatus of claim 22, wherein the switch is further configured to maintain a location tracking database to maintain a number of mobile stations from among the plurality of mobile stations for which the repeater is receiving the received data packets.

24.
