Abstract

Embodiments provide techniques for the transmission of broadcasts. For instance, an apparatus may include a sequence selection module, and multiple radiating elements. The sequence selection module selects sequences of directional transmission patterns, where each selected sequence corresponds to a time period. The multiple radiating elements wirelessly transmit a broadcast at the time periods in accordance with the selected sequences. The broadcast may include, for example, beacons, and/or a data broadcast, and/or a control broadcast and/or a management broadcast.

Claims (37)

1. An apparatus, comprising:

a sequence selection module to select two or more sequences of a plurality of directional transmission patterns, the two or more sequences corresponding to two or more time periods;

a plurality of radiating elements to wirelessly transmit a broadcast, in a full rotation panorama at the two or more time periods in accordance with the two or more sequences.

2. The apparatus of claim 1 , wherein the sequence selection module is to randomly select the two or more sequences.

3. The apparatus of claim 1 , wherein the sequence selection module is to select the two or more sequences in accordance with a round robin technique.

4. The apparatus of claim 1 , wherein the two or more time periods are beacon periods.

5. The apparatus of claim 1 , further comprising: a directional control module to establish operational characteristics for the plurality of radiating elements based on the two or more sequences.

6. The apparatus of claim 1 , wherein each of the plurality of directional transmission patterns corresponds to a sector within an available transmission panorama.

7. The apparatus of claim 1 , wherein the broadcast comprises two or more beacon frames.

8. The apparatus of claim 1 , wherein the broadcast comprises two or more data frames.

9. The apparatus of claim 1 , wherein the broadcast comprises two or more control frames.

10. The apparatus of claim 1 , wherein the broadcast comprises two or more management frames.

11. A method, comprising:

selecting a first sequence of a plurality of directional transmission patterns;

sending, within a first time period, a wireless broadcast in a full rotation panorama in accordance with the first sequence of the plurality of directional transmission patterns;

selecting a second sequence of the plurality of directional transmission patterns; and

sending, within a second time period, the wireless broadcast in a full rotation panorama in accordance with the second sequence of the plurality of directional transmission patterns;

wherein the second sequence is different than the first sequence.

12. The method of claim 11 , wherein the first time period is within a first superframe, and the second time period is within a second superframe.

13. The method of claim 12 , wherein the wireless broadcast comprises a first beacon frame in the first superframe and a second beacon frame in the second superframe.

14. The method of claim 12 , wherein the wireless broadcast comprises a first data frame in the first superframe and a second data frame in the second superframe.

15. The method of claim 12 , wherein the first and second superframes are consecutive superframes.

16. The method of claim 11 :

wherein said selecting the first sequence and said selecting the second sequence are in accordance with a random selection technique.

17. The method of claim 11 :

wherein said selecting the first sequence and said selecting the second sequence are in accordance with a round robin technique.

18. The method of claim 11 , wherein each of the plurality of directional transmission patterns corresponds to a sector within an available transmission panorama.

19. An article comprising a non-transitory machine-accessible medium having stored thereon instructions that, when executed by a machine, cause the machine to:

select a first sequence of a plurality of directional transmission patterns;

send, within a first time period, a wireless broadcast in a full rotation panorama in accordance with the first sequence of the plurality of directional transmission patterns;

select a second sequence of the plurality of directional transmission patterns; and

send, within a second time period, the wireless broadcast in a full rotation panorama in accordance with the second sequence of the plurality of directional transmission patterns;

wherein the second sequence is different than the first sequence.

20. The article of claim 19 , wherein the wireless broadcast comprises a first beacon frame in a first superframe and a second beacon frame in a second superframe.

21. The article of claim 20 , wherein the first and second superframes are consecutive superframes.

22. The article of claim 20 , wherein first and second sequences are selected in accordance with a random selection technique.

23. The article of claim 20 , wherein the first and second sequences are selected in accordance with a round robin technique.
