《中國要聞》工信部明確TD-LTE4G頻段劃分,中移動占大份
VOLTE具有低成本、頻譜利用率高、接續時延低、業務形態豐富等優勢。在今年6月舉行的GTI亞洲大會上,中國移動正式發布了VOLTE白皮書,明確將VOLTE作為LTE語音目標方案,並制定了詳細的部署計劃:今年第四季度進行小規模測試;2014年第二季度進行外場試驗;2014年第三、四季度實現全國VOLTE商用。
雖然我國三大運營商采取了三張技術不同的3G制式,為4G演進埋下了一些伏筆,不過在中國這個神奇的國度,往往最後的演進結果會與出人意料。中國移動在4G網絡下的選擇很清晰,那便是選擇具有國產自主知識產權的TD-LTE標准,其已經早早進行該網絡的大規模測試;中國聯通雖然也參與了TD-LTE的網絡建設,但顯然其會把大部分力量放在FDD-LTE網絡上,這也是其既定的戰略;電信方面同樣也是傾向FDD網絡的建設,其也不只一次表示如果獲得TD-LTE牌照後,會向中移動租用基站等方式運營TD-LTE網絡,明確了投資重點依然在FDD上,業界會認為電信會讓3G、4G和固網WIFI等多種方式協同運營。
