2. Many antennas - Wikipedia

   en.wikipedia.org/wiki/Many_antennas

   Many antennas [1] is a smart antenna technique which overcomes the performance limitation of single user multiple-input multiple-output (MIMO) techniques. In cellular communication, the maximum number of considered antennas for downlink is 2 and 4 to support 3GPP Long Term Evolution (LTE) and IMT Advanced requirements, respectively.

3. 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 ...
