                                               北京聯通:年底基本實現4G網絡全市覆蓋

中國聯通北京分公司19日宣布,預計今年年底,北京聯通可基本實現本市的4G網絡覆蓋。

  北京聯通是在當日舉行的沃4G發布暨終端品鑒會上透露上述信息的。這是北京成為中國聯通LTEFDD/TD-LTE混合組網試驗城市後,北京聯通首次正式發布4G網絡覆蓋情況并提出打造“雙4G雙百兆”高速網絡。

  據悉,目前北京聯通的4G網絡已覆蓋城區及全部縣城區域,并延伸覆蓋機場等部門重要區域。此外,室内站終點覆蓋高校、重點商務區域樓宇、高檔寫字樓、醫院、大型購物中心及北京聯通重要營業廳等。

  北京聯通相關負責人當日稱,未來聯通将秉承3G??的優良品質,攜手“雙4G雙百兆”高速網絡,打造完美用戶體驗。
 

  據了解,目前國内使用的4G有兩種制式,分别是LTEFDD和TD-LTE,中國聯通采用LTEFDD和TD-LTE混合組網的形式,即雙4G,意思就是既能用LTEFDD也能用TD-LTE制式的4G網絡,可為用戶帶來FDD較高峰值150M/bps和TD峰值100M/bps的極速網絡體驗。

  在“雙4G雙百兆”高速網絡開通的同時,北京聯通還同步推出了多款4G套餐,包括更為優惠的4G本地組合套餐和4G領航卡,面向家庭用戶的4G共享組合套餐,以及面向手機用戶的合約惠機計劃。
