飞天联合CEO段世平:空中上网大规模使用已有技术基础

2017-09-21 07:07:15   中国经济网

每经记者 李少婷 每经编辑 张海妮

民航局“松绑”飞机上便携式电子设备的使用,为此前低调开拓市场的机载WiFi产业带来了爆发契机。在民航局放出消息的第二天,A股市场为数不多的几家机载WiFi概念股开盘即涨,其中,辉煌科技(002296,SZ)9月19日开盘涨停,9月20日收盘涨6.42%;北纬科技(002148,SZ)19日上涨3.31%。

辉煌科技成为概念股,源于其持有飞天联合(北京)系统技术有限公司(以下简称飞天联合)23.3482%股权,而飞天联合主要业务为航空机载WiFi及火车车载WiFi,被辉煌科技认为是其“大交通WiFi战略”实现的重要部分。2011年成立的飞天联合在机载WiFi已蛰伏6载。据飞天联合CEO段世平介绍,其公司是国内第一家完全自主研发的飞机WiFi整套系统提供商,而此次政策松动被飞天联合CEO段世平认为有“节点性”意义。

9月19日,《每日经济新闻》记者(以下简称NBD)专访段世平,对机载WiFi产业的爆发基础及前景做了深入探讨。

中国机载WiFi有后发优势

NBD:机载WiFi的技术路径大致分为ATG和卫星通信,后者是主流。而在卫星通信技术流派中,业内对于是采用Ka频段和Ku频段一直存在争辩,您认为哪个频段是未来的技术主流?

段世平:传统的Ku是带宽非常窄,现在东航大约有60架跨洋国际航线宽体机用的是Ku频段,但实际飞行数据率往往不到10兆甚至更低,使用系统的乘客数量一多体验急速下降,我们认为传统Ku是不适宜长期发展的系统。

现在还有一种叫高通量Ku,系统容量比传统Ku高很多倍,但是就单架飞机来说带宽高不了太多。现在高通量的Ku仅在海外航空有些测试,国内目前还没有,可能有一定的机会。

我们主张采用高通量的Ka频段。满足大规模机队商业运营的机上网络使用必须用高通量Ka。我国今年4月刚刚发射的中星16号卫星,是最新一代Ka频段的高通量卫星,容量为20G,单架飞机带宽理论值是超过100兆,飞天联合公司提供的针对中星16号卫星的机载IFEC系统最近实测值最高时超过71兆。

据第三方信息,霍尼韦尔等国际厂商的机载WiFi系统基于高通量Ka的机载WiFi系统带宽最高到49兆,相较于我们测试的71兆低一些,从这一点来看,中国的机载WiFi供应商具有后发优势,我们国产设备实测带宽性能指标一点都不弱于国际大牌。

NBD:卫星的频段资源是有限的,目前的Ka频段资源可以满足需求吗?
