version date3.0 1/30/2008
first NE version- several improvements according to enabling slides (30.01.08) - sheet "link budget" - cell entered for "burst allocation loss" - SINR figures updated - CDD implemented - DL FCH channel added - indoor lognormal fading margin added - sheet "capacity" - "low" load TM with RR scheduler - full buffer TM with RR scheduler - sheet "dimensioning" - "average # of concurrent VoIP users per cell" computed - "achieved load" computed - load used as input- new sheet: "Technical data & key values"
