Abstract

In a method and access point, a first packet of a plurality of packets is selected, this selection being based on a destination address of each packet and information about at least one previous selection of a second packet, and the selected packet is transmitted.

Claims (20)

1. A method, comprising:
selecting a packet for transmission, wherein the packet is one of at least two packet types;
determining whether a communications medium is busy;
selecting, when the communications medium is busy, one of a first time duration when the packet is a first type and a second time duration when the packet is a second type;
and transmitting the packet after one of the first time duration when the packet is the first type and the second time duration when the packet is the second type.
2. The method of claim 1, wherein the first time duration is one of a first range of durations and the second time duration is one of a second range of time durations.
3. The method of claim 2, wherein the first range of durations is exclusive of the second range of durations.
4. The method of claim 2, wherein the first range of durations is non-exclusive of the second range of durations.
5. The method of claim 1, wherein the type of the packet is based on a determined priority level of the packet.
6. A system, comprising:
a communication medium for communicating packets;
an access point to receive the packets from the communication medium;

a plurality of remote terminals to transmit packets to the communication medium, wherein, when one of the remote terminals has one of the packets for transmission, the one remote terminal determines whether the communication medium is busy, selects, when the communication medium is busy, one of a first time duration when the packet is a first type and a second time duration when the packet is a second type and transmits the packet after one of the first time duration when the packet is the first type and the second time duration when the packet is the second type.
7. The system of claim 6, wherein the first time duration is one of a first range of durations and the second time duration is one of a second range of time durations.
8. The system of claim 7, wherein the first range of durations is exclusive of the second range of durations.
9. The system of claim 7, wherein the first range of durations is non-exclusive of the second range of durations.
10. The system of claim 6, wherein the type of the packet is based on a determined priority level of the packet.
11. A communication device, comprising:
a transmission queue including a packet to be transmitted, the packet being one of at least two packet types;
a transmitter to determine whether a communication medium is busy, select, when the communication medium is busy, one of a first time duration when the packet is a first type and a second time duration when the packet is a second type and wirelessly transmit the packet after one of the first time duration when the packet is the first type and the second time duration when the packet is the second type.
12. The communication device of claim 11, wherein the communication device is one of a remote terminal and an access point.
13. The communication device of claim 11, wherein the first time duration is one of a first range of durations and the second time duration is one of a second range of time durations.
14. The communication device of claim 13, wherein the first range of durations is exclusive of the second range of durations.
15. The communication device of claim 13, wherein the first range of durations is non-exclusive of the second range of durations.
16. The communication device of claim 11, wherein the type of the packet is based on a determined priority level of the packet.
17. A method, comprising:
selecting a packet for transmission, wherein the packet is one of at least two packet types;
determining whether a communications medium is busy;
selecting, when the communications medium is busy, one of a first time duration when the packet is a first type and a second time duration when the packet is a second type;
and attempting to transmit the packet after one of the first time duration when the packet is the first type and the second time duration when the packet is the second type.
18. The method of claim 17, further comprising:
selecting, when the attempt to transmit is unsuccessful, a third time duration when the packet is the first type and a fourth time duration when the packet is the second type; and attempting to transmit the packet after one of the third time duration when the packet is the first type and the fourth time duration when the packet is the second type.
19. The method of claim 18, wherein the first time duration is one of a first range of durations and the second time duration is one of a second range of time durations.
20. The method of claim 19, wherein the third time duration is one of the first range of durations and the fourth time duration is one of the second range of time durations.
