Page 98 of 102 Appendix D: Key planning concepts553-3601-106 Standard 2.00 September 1996102for planning the system into cells with cell centers. If you do not planthe system properly, auto administration cannot correct your mistakes.Optimizing auto administration• All Base Stations or external antennas in a cell must be as close togetheras possible at the cell center.• Keep different cell centers apart from each other.• Do not put a barrier (such as a large concrete or marble column, or aconcrete wall) between Base Stations at a cell center.• Stagger cell centers on adjacent floors.• Use the left-right-skip method to plan multi-floor sites.• Do not spread Base Stations throughout the coverage area.Portable originated callsFigure 41 : Portable originated callThe portable requests a link on one of the 100 kHz channels and hails thesystem’s name. All Base Station radios throughout the system that are nothandling calls monitor for a portable originated call. These Base Station radiosmonitor one channel at a time, scanning repeatedly through all the channels.(Base Station radios scan independently of each other.)Note: The first Base Station radio to tune into the channel that the portable ishailing on and to recognize the system’s name, answers the portable.(This Base Station is not necessarily the one that is closest to theportable.)Once the system establishes a link, and if the signal strength is below athreshold value, the Base Station radio requests a hand-off in case another cellcenter is closer to the portable.4
