12. A method for equalizing gain when transmitting control information from a plurality of antenna configurations, the method comprising:
producing a set of quasi-omni beams having complementary beam patterns that form an aggregate beam pattern providing omni-directional coverage, each of the set of quasi-omni beams having at least a first antenna gain,
producing a set of directional beams, each of the set of directional beams having at least a second antenna gain, the at least second antenna gain being different than the at least first antenna gain, and
generating a first beacon frame having a first spreading gain to be transmitted on each of the set of quasi-omni beams and a second beacon frame having a second spreading gain to be transmitted on each of the set of directional beams, wherein generating further comprises selecting the first spreading gain and the second spreading gain such that the sum of the first spreading gain and the first antenna gain equals the sum of the second spreading gain and the second antenna gain.
13. The method recited in claim 12, wherein selecting the first spreading gain and the second spreading gain comprises selecting at least one of a Golay code length and a number of repetitions.
14. A method for determining a preferred set of beam patterns for transmitting information between a network controller and a subscriber device, the method comprising:
detecting a quasi-omni signal transmitted with a quasi-omni beam pattern by the network controller,
reading beacon-frame information in the quasi-omni signal,
employing the beacon-frame information to assist in detecting a plurality of directional signals, each transmitted with one of a plurality of directional beam patterns by the network controller,
calculating a link-quality factor for each of a plurality of combinations of beam pattern employed by the subscriber device and directional beam pattern employed by the network controller, and
transmitting a request to the network controller indicating at least one preferred directional beam pattern to use when communicating with the subscriber device.
15. The method recited in claim 14, wherein detecting a quasi-omni signal further comprises setting a predetermined time limit for determining if detection was successful, and upon unsuccessful detection, performing at least one of a set of functions, comprising notifying the network controller that detection was unsuccessful and directing the subscriber device to go into a sleep mode.
16. The method recited in claim 14, wherein calculating the link-quality factor for each of the plurality of combinations further comprises storing each link-quality factor.
17. The method recited in claim 14, wherein calculating the link-quality factor for each of the plurality of combinations comprises calculating the link-quality factor for all possible combinations of beam pattern employed by the subscriber device and directional beam pattern employed by the network controller.
18. The method recited in claim 14, wherein calculating the link-quality factor for each of the plurality of combinations further comprises storing a predetermined number of the combinations sorted by link-quality factor for providing a set of best combinations.
19. The method recited in claim 18, further comprising repeating the step of calculating the link-quality factor for each of the plurality of combinations for only the set of best combinations.
20. The method recited in claim 14, wherein transmitting the request comprises transmitting the request during at least one predetermined listening period.
21. The method recited in claim 14, wherein transmitting the request is followed by the network controller transmitting an acknowledgment to the subscriber device.
