Why optimisation ?Why optimisation ? • quality of radio coming up with - applied mathematics variations within the path loss characteristics - Finite parcel of land information resolution • Implementation - Antenna graph and effective radiated power glowing Technologies Proprietary Use consistent to Company directions - All Rights Reservedde No.5 glowing Technologies - Antenna graph and effective radiated power - Antenna pattern distortion • setting - seasonal environmental changes, e.g trees, leaves - Environmental changes like new highways, new buildings quality of radio coming up with applied mathematics variations within the path loss characteristics Finite parcel of land information resolution Antenna graph and effective radiated power glowing Technologies - Proprietary Antenna graph and effective radiated power seasonal environmental changes, e.g trees, leaves Environmental changes like new highways, new buildings
6. Single Band optimisation PhilosophySingle Band optimisation Philosophy Coverage - sensible amplitude across the full cell, coverage holes at intervals a cells topographic point should be reduced. Interference - an inexpensive level of interference should be contained at cells topographic point so as to produce a top quality air glowing Technologies Proprietary Use consistent to Company directions - All Rights Reservedde No.6 glowing Technologies topographic point so as to produce a top quality air relinquishment Behavior - the standard of the air to relinquishment behavior is nice, no excess handovers, Rxquality at acceptable level, BTS & MS use minimum transmit power. Traffic Distribution - the standard of the air to traffic distribution is nice, most quantity of traffic may be bimanual.
