CDMA Sunset - Across the Globe CDMA Networks Shutting Down

As technology grows, old ones become obsolete and new ones are welcomed. Same is happening with CDMA (Code Division Multiple Access). The death of CDMA was filed a long ago in 2008 when Qualcomm, the company behind CDMA stopped R&D on UMB - the next of CDMA family favoring LTE as future.

Worldwide CDMA is not well accepted, though everyone knows about its advantages as a data platform. CDMA is well received and commercially popular in few countries like United States, Canada, South Korea, Russia, India, Australia, China, Indonesia, Nigeria and others. In most contries CDMA is deployed (on 800 or 450 Mhz band) for other uses like emergency services, military communications, M2M services. 


In Canada there were several CDMA players - top 4 has already made plans to wind up CDMA. Here operators want to free up CDMA spectrum for deploying LTE. First they cut EVDO - so that data users move to LTE, and then CDMA 1x will be phased out in time so that voice customers get time to migrate.
