Performance Indicator Formula (RANK2)
Footnote :
• Even all sectors in one site have good ASM result, TxRank2 statistics not always show value higher than 20%.
• As this TxRank2 depends on
• the coverage of the antenna’s beam pointing to
• UE location distribution (on cell centre/cell edge)
• number of traffic/connected users, traffic unbalance etc
