cdma2000/CDMA 測試
分碼多工存取 (CDMA) 技術也和產業需求一樣演進和趨於成熟,這是一項以 TIA/EIA IS-95 CDMA 標準 (包括 IS-95A 和 IS-95B 版本) 為基礎的數位蜂巢技術,CDMA 最早推出時是做為語音通訊的解決方案,採用了使用數位碼的直接序列調變,以擴展其頻譜。
隨著使用者設備和應用的演進,cdma2000 取代了 CDMA,cdma2000 是由電信產業協會 (Telecommunication Industry Alliance) 開發的技術,支援電路切換語音通訊,以及單一 1.25 MHz 通道中最高達 307 kbps 的封包資料速率。
另一項從 CDMA/cdma2000 演進而來的技術是 1xEV-DO (1x Evolution,僅限資料)。如需關於這項 cdma2000 空中介面增強技術 (經過最佳化,適用於封包資料傳輸) 的詳細資訊,可參閱安捷倫 1xEV 技術網頁 1xEV-DO Test
安捷倫科技提供 cdma2000/CDMA 產品、解決方案和服務,適用於參與設計、整合、製造的工程師與技術經理,以及新一代網路的效能。因此,在您邁向 CDMA 時,安捷倫為您鋪路。
