移動在 12 月正式商用 TD-LTE 的 4G 網絡，有用戶嘗試用 iPhone 5s/5c 破解運行在移動 TD-LTE 網絡上，發現其語音通話質量較差，具體表現為延時加長、出現電話斷線、聲音不清晰等情況，這當中原因一方面有移動 4G 網絡尚未優化成熟，另外一方面也與 iPhone 所採用的 CSFB 語音回落技術有關。不過運行在 4G 網絡上的 iPhone 會出現這個問題，但是同為 4G 版本的三星 Note3 卻沒有用戶反映，這主要是兩部手機在 4G 網絡下所採用的語音通話技術有所差異，接下來一起了解。 三星 Note3 4G 語音技術解析

威盛專利賣聯發科 百億入袋
處理器廠威盛透過子公司手機晶片廠威睿電通（VIA Telecom），將 CDMA2000 專利授權給聯發科，威睿將可收取 3 ~ 3.5 億美元（逾新台幣 100 億元）的授權金，威盛因認列該授權金 50 億元收益，對每股淨利挹注超過 10 元，等於大賺逾一個股本。 近期手機供應鏈傳出，威盛旗下手機晶片廠威睿已將 CDMA2000 專利授權給聯發科，聯發科在取得授權後，將可推出支援 TD-SCDMA/WCDMA/CDMA2000 的 3 模手機系統單晶片，以及加入 4G 規格的 6 模手機晶片。對聯發科來說，因為補齊了 3G 專利缺口，不僅可以與高通正式對決，因為三星採用威睿晶片多年，聯發科也可因此直接打入三星智慧型手機供應鏈。 但對此一消息，威盛及聯發科均表示，不回應市場傳言。 相關業者指出，CDMA2000 規格市場尚有 5 億支的功能型手機尚未轉換至智慧型手機，以手機業界專利授權經驗推估，此次威盛及威睿將 CDMA2000 專利授權給聯發科，聯發科付出的授權金將達 3 ~ 3.5 億美元（約逾新台幣 100 億元）。由於威盛持股威睿近 … Continue reading
