B . Cell-edge rates are the worst 5 percentile of the over all data rate distribution in the cell, 64 QAM not considered for Rev. B
Cell edge performance can be traded for even higher cell capacity at the expense of fairness

Rev. B and 1X EverywhereRev. B for similar user experience outside LTE ; 1X for voice services everywhere
Similar Rev. B LTE Performance
LTE Best suited to leverage new and wider contiguous spectrum

LTE relative performance decreases with bandwidth due to higher overhead; 40% overhead in 1.4 MHz vs. 25% in 20 MHz results in 25% better relative performance in 20 MHz vs. 1.4 MHz.
