Abstract

A wireless access point is provided for transmitting radio signals that has isolators positioned about the perimeter of the wireless access point dividing the perimeter of the wireless access point into segments and reflector plates positioned within each segment for directing the transmission of the radio signals within each segment.

Claims

1. A wireless access point for transmitting radio signals, the wireless access point comprising:

isolators positioned about the perimeter of the wireless access point dividing the perimeter of the wireless access point into segments, and

a reflector plate positioned within each segment for directing the transmission of the radio signals within each segment.

2. The wireless access point of claim 1 where the isolators are foam.

3. The wireless access point of claim 1 where the reflector plates include a ground plate.

4. The wireless access point of claim 1 where the reflector plates include a deflective ring.

5. The wireless access point of claim 1 where the reflector plates include both a deflective ring and a ground plate.

6. The wireless access point of claim 1 where the wireless access point is generally circular in shape.

7. The wireless access point of claim 1 where the wireless access point is generally elliptical in shape.

8. A wireless access point for transmitting radio signals, the wireless access point comprising:

a plurality of antenna sectors;

absorptive isolators located between each antenna sector

a reflective surface within each antenna sector for directing the transmission of radio signals within each antenna sector; and

a deflective surface within each antenna sector for directing the transmission of radio signals within each antenna sector.

9. The wireless access point of claim 8 where the wireless access point further includes a digital section and the deflective surface acts as an isolation barrier between the central digital section and the antenna sectors.

10. The wireless access point of claim 8 where the antenna sectors are arrayed in a generally circular pattern and are capable of transmitting signals outwardly 360 degrees from the center of the wireless access point.

11. The wireless access point of claim 8 where the antenna sectors are arrayed in a generally circular pattern and are capable of transmitting signals 180 degrees upward from the wireless access point.

12. The wireless access point of claim 8 where the absorptive isolators are foam.

13. The wireless access point of claim 8 where the reflector surface includes a ground plate.

14. The wireless access point of claim 8 where the deflector surface includes a ground plate.

15. The wireless access point of claim 8 where the reflector surface includes a reflective ring.

16. The wireless access point of claim 8 where the reflector surface includes a both a reflective ring and a ground plate.

17. The wireless access point of claim 8 where the wireless LAN array is generally round in shape.

18. The wireless access point of claim 8 where the wireless LAN array is generally elliptical in shape.

19. The wireless access point of claim 8 where wireless access point further includes a digital suppression element and where the digital suppression element, antenna reflective surface and antenna deflector surface are made from one contiguous piece of conductive and reflective material and are inherently grounded together.
