2. CDMA2000 - Wikipedia

   en.wikipedia.org/wiki/CDMA2000

   CDMA2000 (also known as C2K or IMT Multi‑Carrier (IMT‑MC)) is a family of 3G [1] mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites. It is developed by 3GPP2 as a backwards-compatible successor to second-generation cdmaOne (IS-95) set of standards and used especially in North America ...
