Reply To: Erlang formula for Dual Rate TCH


I have seen tables for traffic HR calculation. Entries are HR penetration against FR TCH, these are based on simulation models.
But i believe it is also necesary to consider the thresholds defined for BTS and BSC to access or not to HR resources.

About MS supporting HR most of vendors are including now AMR capable instead of HR because it gives you better quality and improve resources utilization.
