重庆晚报讯 市经信委主任沐华平昨日作客新华网时透露,重庆4G研发进进测试阶段,市民有看两年内用上4G产品。
沐华平说,尽管3G技术还处于普及状态,但重邮信科已进行了4G开发,现在正式进进测试阶段。他说,在带宽能够达到要求的条件下,假如把现在的3G比作一条马路,4G就是把马路拓得更宽,那样车辆行驶起来就会更快。以网速为例,目前3G传输速度一般在2.8Mb/秒左釉冬而4G传输的速度可以达到100Mb/秒,约为3G的36倍。目前国外已生产出4G芯片,国内也有不少单位在研究该项技术,重庆现在就拿出了产品,尽管还处在内部自测阶段,但在国内肯定算走在前头的。
“4G研发重庆已经比较成熟,但推广却需要时日,主要取决于大规模的网络部署。”市经信委软件处处长居琰说,目前重邮信科除了在重庆本地进行测试外,在全国其他城市也在同步测试,在技术储备方面取得了很好的成绩。
居琰说,要推广4G,最大的困难在于网络运营商的布网速度,由于只有展设了高速网络,4G技术才能进进千家万户。他预计,由于有巨大的市场潜力,运营商的网络展设多则三五年,少则一两年,市民便能享受4G生活。届时,用手机打联机游戏、视频通话将像使用文字聊天一样快速、便捷。
