Abstract

Remote units are mounted in a support structure so that cooling air flow is not impeded by the support structure. The remote units may have RF communications circuitry and other components that generate heat in the provision of wireless services.

Claims

1. An installation assembly for a remote unit of a distributed communication system, comprising:

a remote unit comprising an enclosure and at least one antenna unit capable of transmitting RF communication signals into a coverage area, the remote unit being configured for mounting within a mounting aperture of a support structure so that a first side of the remote unit is visible at a first side of the support structure and a second side of the remote unit is opposite to the first side of the remote unit; and

a mounting component secured to the remote unit,

wherein the remote unit has at least one ventilation aperture to allow cooling air to flow between the first and second sides of the remote unit and between the first side and a second side of the support structure.

2. The installation assembly of claim 1, wherein the mounting component includes a support mount configured to abut the second side of the support structure and a remote mount connected to the second side of the enclosure.

3. The installation assembly of claim 1, further comprising a flange configured to at least partially cover the mounting aperture.

4. The installation assembly of claim 1, wherein the remote unit comprises a circuit board and a heat sink.

5. The installation assembly of claim 1, wherein the first and second sides of the support structure are generally planar surfaces.

6. The installation assembly of claim 1, wherein the at least one ventilation aperture comprises a plurality of first ventilation apertures at a first side of the enclosure and a plurality of second ventilation apertures at a second side of the enclosure.

7. The installation assembly of claim 1, wherein the first side of the remote unit protrudes beyond the first side of the support structure.

8. The installation assembly of claim 1, wherein the second side of the remote unit protrudes beyond the second side of the support structure.

9. An installation assembly for a remote unit of a distributed communication system, comprising:

a support structure having a first side, a second side, and a mounting aperture extending from the first side to the second side;

a remote unit comprising an enclosure and at least one antenna unit capable of transmitting RF communication signals into a coverage area, the remote unit being disposed within the mounting aperture so that a first side of the remote unit is visible at the first side of the support structure; and

a mounting component secured to the remote unit and secured to the support structure,

wherein the remote unit has at least one ventilation aperture to allow cooling air to flow between the first and second sides of the remote unit and between the first side and second sides of the support structure.

10. The installation assembly of claim 9, wherein the mounting component includes a support mount configured to abut the second side of the support structure.

11. The installation assembly of claim 9, further comprising a flange configured to at least partially cover the mounting aperture.

12. The installation assembly of claim 9, wherein the remote unit comprises a circuit board and a heat sink.

13. The installation assembly of claim 9, wherein the first and second sides of the support structure are generally planar surfaces.

14. The installation assembly of claim 9, wherein the at least one ventilation aperture comprises a plurality of first ventilation apertures at a first side of the enclosure and a plurality of second ventilation apertures at a second side of the enclosure.

15. The installation assembly of claim 9, wherein the first side of the remote unit protrudes beyond the first side of the support structure.

16. The installation assembly of claim 9, wherein the second side of the remote unit protrudes beyond the second side of the support structure.

17. The installation assembly of claim 9, wherein the remote unit has height H extending generally perpendicular to the support surfaces and a width W, the width W being at least twice the height H.

18. The installation assembly of claim 9, wherein the support structure is adapted to be accommodated within a building ceiling tile support frame.

19. The installation assembly of claim 9, wherein the support structure is generally rectangular and is adapted to be accommodated within a ceiling tile support frame for ceiling tiles having sides two feet in length.

20. The installation assembly of claim 9, wherein the support structure comprises either a section of a wall or a ceiling in a deployment infrastructure.
