  CDMA2000 1x采用直接序列擴頻碼分多址(DS-CDMA)、頻分雙工(FDD)方式,碼片速率為1.2288Mcps,載波帶寬為1.25MHz。

  CDMA2000 1x EV-DO(也稱為HRPD)技術,主要對數據業務進行了增強,不支持語音,在1.25MHz的帶寬內可提供最高2.4Mbps的下行數據傳輸速率" title="傳輸速率">傳輸速率。DO Rel 0版本已經在韓國、美國和日本等國家商用。目前正在向DO Rel A版本發展,該版本在1.25MHz的帶寬內可提供最高3.1Mbps的下行數據傳輸速率。在DO Rel A的基礎上,采用多載波" title="多載波">多載波捆綁的方式進一步提高數據速率,形成了DO Rel B標準,也稱為空中接口演進(AIE)Phase 1,該標準已經發布。而目前3GPP2正在制定 AIE Phase 2標準,與3GPP的LTE演進類似,同樣以OFDM、MIMO等技術為基礎。
