When Qualcomm placed the first CDMA call over 25 years ago, few could have imagined that it would still be going strong today. Yet here we are, continuing to invest in and improve global CDMA connectivity.
Qualcomm created CDMA in 1985. By 1993, CDMA had established itself as one of the two global wireless communication standards.
The upgrade from Rev. A uses more channels and a highly optimized modem to improve data rates and capacity.
This cost-effective software upgrade takes advantage of unevenly loaded networks to maximize performance.
The evolution from CDMA2000 1X can offer 4x more voice capacity or up to 70% more coverage.
