DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows a front view of a prior art telecommunications base station electronics system. The prior art system consists of a number of component sections (i.e., shelves), and comprises antennae 11 (two are shown), filters 12, amplifiers 14, radios 16 and channel cards 18, fan tray 13 (positioned between the shelf comprising filters 12 and the shelf comprising amplifiers 14), and fan tray 15 (positioned between the shelf comprising amplifiers 14 and the shelf comprising radios 16 and channel cards 18). The typical prior art provides the various component sections (ie., shelves) stacked on top of each other in order to provide easy access to all of the components from the “front” of the cabinet. As is typical, the back sides of many of these components may be connected to either a cabling harness or a PWB (Printed Wiring Board) backplane. (Note that the lower shelf comprising both radios 16 and channel cards 18, which advantageously operate together to send and receive signals.)
FIG. 2 shows a side view of the prior art telecommunications base station electronics system of FIG. 1. In addition to the components shown in FIG. 1, FIG. 2 shows back-plane 17 to which the back sides of many of the components are connected. (Note that back-plane 17 may alternatively comprise a wiring harness.) Note also that the prior art telecommunications base station electronics system of FIGS. 1 and 2 may be installed in a permanent location with the “back” of the system (i.e., the right side of the side view shown in FIG. 2) affixed to a wall, since all components may be accessed from the “front” of the cabinet (i.e., the left side of the side view shown in FIG. 2).
FIG. 3 shows a top view of a compact functionally layered telecommunications base station electronics system in accordance with a first illustrative embodiment of the present invention. The illustrative base station of FIG. 3 advantageously comprises a plurality of hinged layers (i.e., shelves) which may be opened to provide access to otherwise inaccessible layers. (See FIG. 5 and the discussion thereof below.) In particular, the illustrative base station of FIG. 3 comprises (two) antennae 31, filters 32, amplifiers 34, radios 36, channel cards 30, back-plane 37 and front-cover 40, as well as hinge 38, U-shaped cable 35 and hinge 39. U-shaped cable (i.e., wiring harness) 35 advantageously provides necessary electrical connections between back-plane 37 and amplifiers 34, radios 36, and channel cards 30.
The illustrative base station of FIG. 3 specifically comprises 3 individual layers plus front cover 40, each of which may advantageously be individually accessed with use of hinge 38 and/or hinge 39. One such layer comprises antenna 31 and filters 32 (along with back-plane 37); a second such layer comprises amplifiers 34; and a third such layer comprises radios 36 and channel cards 30. (Note again that radios 36 and channel cards 30 advantageously operate together to send and receive signals.) Hinge 38 may be advantageously operated to provide access to filters 31 as well as to amplifiers 34, while hinge 39 may be advantageously operated to provide access to radios 36 and channel cards 30 (by opening front cover 40).
