LTE CDMA is a third generation (3G) mobile technology that offers high speed data rates and improved capacity over existing CDMA2000 1xEV-DO networks. LTE CDMA is an upgrade to the current 3G network and allows for higher data speeds, increased capacity, and lower latency. The main difference between global LTE CDMA and GSM UMTS is that LTE CDMA uses a different air interface than GSM UMTS. While both technologies are based on the same general principles, they use different techniques to achieve their high speeds.
