There is a material difference between UMTS and LTE, UMTS is using CDMA which comes with some practically unfortunate tradeoffs like the "breathing cell" and inheriting the old GSM style slow system design.
- fredliu 9y agoSure, CDMA vs OFDM, definitely they can be regarded as "material difference" But that's not the logic/argument the original article made. They only used bandwidth and delay to quantify "material difference". Following their logic, they can make the same argument for 3G vs 4G back in the day.
