Page 26 of 102 Site planning basics553-3601-106 Standard 2.00 September 1996Cell center locationCovering outdoor areasNote: The customer decides whether the site requires outdoor coverage.Cover outdoor areas before covering indoor areas.Use the CDT to determine the outdoor coverage provided by a Base Stationlocated indoors. Because you cannot use the CDT transceiver outside, useTable 6 on page 28 to estimate the coverage of outdoor external antennas.For each cell center requiring outdoor external antennas, it is best to plan fortwo, four, six or eight outdoor external antennas. Connect each pair of outdoorexternal antennas at a cell center to the same Base Station. If you only connectone radio to an external antenna serving the same cell center, it is best todisconnect the other radio. If you use external antennas and you have the tworadios in the same Base Station serving different cells, users in the area couldhave poor audio quality links and they could drop their calls.Steps for outdoor planning1. Note each of the critical points that you want to reach.2. Position the CDT transceiver indoors at the potential location for a cellcenter that is closest to the critical point (preferably next to a window).3. Take your portable outdoors and determine if the critical point is withinthe cell boundary.If the critical point is within the cell boundary, your cell center is at theposition of the CDT transceiver. Determine and record the cell boundaryfor the cell center (both indoors and outdoors) on the floor plan (see“Cell center location” on page 26).If the critical point is not within the cell boundary, determine and recordon the floor plan the cell boundary that you did reach.4. For each critical point that cannot be reached, determine a potentiallocation for outdoor external antennas using the following criteria:— Is it outdoors?— Is it as close as possible to the critical point you need to reach?2
