Interim Standard 95 (IS-95), is the first CDMA-based digital cellular standard pioneered by Qualcomm. The brand name for IS-95 is cdmaOne. IS-95 is also known as TIA-EIA-95.


It is now being supplanted by IS-2000. It is used in the US and in Korea.

The first CDMA networks in the form of IS-95 / cdmaOne were the first deployments of CDMA technology, the technology that is being used for all 3G cell phone systems.
