未來較值得關注的是802.16m task group的發展，IEEE成立該工作小組的目的在於制定802.16新一代標準，此外，另一項重要的任務是將讓802.16技術可以完全相容並滿足下一世代IMT-Advanced的要求，使802.16技術可以在全球下世代行動通訊標準介面中取得一席之地，目前該工作小組對於未來標準制定的時程規劃仍不明朗，未來發展動態值得持續觀察。作者: chip123 時間: 2008-3-4 11:47 AM 標題: LitePoint IQfact Meets Beceem Calibration Standards Software qualified for Beceem's BCS200 Mobile WiMAX terminal chipset . @% f; G.
