1. A method, comprising:
- configuring, by a switch, a plurality of repeaters operating at a substantially identical communication frequency to coordinate transmissions of first and second data packets to first and second mobile stations, respectively, that are wirelessly communicatively coupled to a repeater from among the plurality of repeaters, the first data packet being characterized as having a first address that corresponds to the first mobile station and the second data packet being characterized as having a second address that corresponds to the second mobile station;
performing, by the switch, an address translation on the first and second addresses to identify a switch port from among a plurality of switch ports that corresponds to the repeater;
determining, by the switch, whether wirelessly transmitting the first and second data packets from the repeater to the first and second mobile stations, respectively, will create interference between the first and second data packets; and
transmitting, by the switch, the first and second data packets through the switch port to the repeater at different times when it is determined that wirelessly transmitting the first and second data packets from the repeater will create interference.

Abstract
A method and apparatus for communicating between devices is described. In one embodiment, the method comprises one or more communication devices coordinating transmissions of data packets to function as an access point with respect to a first mobile station and a second station wirelessly communicatively coupled to the one or more communication devices, and the one or more communication devices wirelessly transmitting a first packet and a second packet to the first mobile station and the second mobile station respectively at different time or at time when the transmissions overlap, at least partially, based on whether transmissions of the first and second packets would interfere with each other.

14. A method, comprising:
-
receiving, by a switch, first and second data packets designated for transmission to a first mobile station and a second mobile station, respectively, via a plurality of repeaters transmitting on a substantially identical communication frequency, the first data packet being characterized as having a first address that corresponds to the first mobile station and the second data packet being characterized as having a second address that corresponds to the second mobile station; performing, by the switch, an address translation on the first and second addresses to identify a switch port from among a plurality of switch ports that corresponds to the repeater; detecting, by the switch, whether overlapping transmissions of the first and second data packets will result in interference that would prevent completion of transmissions of the first and second data packets; and scheduling, by the switch, the transmissions of the first and second data packets via the switch port to avoid the interference if the overlapping transmissions of the first and second data packets will result in interference that would prevent completion of the transmissions of the first and second data packets. - View Dependent Claims (15, 16, 17)

18. A method, comprising:
-
receiving, by a switch coupled to a plurality of repeaters, a data packet destined to a mobile station, the data packet being characterized as having an address that corresponds to the mobile station; performing, by the switch, an address translation on the address to identify a switch port from among a plurality of switch ports that corresponds to a repeater from among the plurality of repeaters that is wirelessly communicatively coupled to the mobile station; determining, by the switch, whether immediately transmitting the packet from the repeater to the mobile station will cause an interference with other communications destined to the mobile station; and
transmitting, by the switch, the packet through the switch port to the repeater when it is determined that immediately transmitting the packet will not cause interference. - View Dependent Claims (19, 20, 21, 22, 23, 24)
