1X Advanced includes a collection of enhancements that can theoretically increase voice capacity by up to 100 Erlangs, or a factor of four over legacy CDMA2000 1X networks. To put this into perspective, this industry-leading voice technology can support more than 80 times the number of calls than older analog networks. 1X Advanced allows an operator to tradeoff this capacity improvement to increase network coverage by up to seventy percent or triple 1X data network capacity.
