美国5G Open RAN再遭重大挫败,抗衡中国5G技术的图谋已告失败

近日美国知名的 Open RAN供应商Parallel Wireless进行大规模裁员,裁员比例至少五成,此前美国运营商已公开诉苦指出5G ORAN的设备不可靠并且成本太高而计划拆除这类5G设备,如今连供应商也撑不下去了,代表这美国图谋5G技术话语权的计划基本已经失败。

目前全球正在推进5G商用,而5G专利的主要贡献者是中国的华为和中兴,中国众多通信企业合计贡献了5G核心专利的四成,在全球诸多经济体中高居第一名。

从2G到5G,中国成功从跟随者变成领导者,代表着中国在移动通信技术上的巨大进步,伴随着中国在移动通信技术上的话语权不断增强,中国也培育起了自己完善的移动通信产业链,芯片、设备、手机等形成了一条完整的产业链。

相比之下,美国则在全球移动通信技术领域的话语权不断下滑,为了取得更多话语权,美国在5G技术上先是提出5G毫米波技术,却因为5G毫米波技术成熟度不足以及成本太高,导致全球仅有美国以及南美等有限的5家运营商采用5G毫米波技术,如今美国的运营商已转回5G厘米波乃至低频5G技术,5G毫米波技术只被美国运营商用于固网宽带的补充。

5G毫米波技术基本失败后,美国又提出了5G Open RAN标准,这是因为美国早已没有了通信设备商,于是希望利用美国Intel占有优势的服务器芯片业务,以打破当前由通信设备商供应5G设备的格局,然而美国运营商表示5G Open RAN设备太不可靠以及成本太高而计划拆除部署设备,再到如今5G Open RAN供应商严重亏损而大举裁员,再让美国的图谋遭受重挫。

美国5G Open RAN遭遇挫败其实是早已注定的,因为当下的5G网络极度复杂,由于它采用了更宽的频谱,因此采用了诸多复杂的射频单元,据称5G的天线数量是4G的1-2倍,而不同的市场还有不同的频谱,例如中国除了全球通用3.5GHz频段之外,还有2.6GHz、4.9GHz,去年下半年又增加了700MHz频段,这导致5G基站的天线数量进一步倍增。

同时当下的移动通信网络还有4G、5G网络共存,甚至出现2G、3G、4G、5G网络共存的现象,导致移动通信网络的建设和优化成为一项高度复杂的工程。如此复杂的系统工程,也就要求设备商有极高的技术水平,确保如此多的设备在一起运行中足够可靠,需要专业的企业提供专业的服务。

事实上从3G以来,欧洲的运营商就逐渐减少自己的网络运维工作,而将这类工作交给设备商负责,因为设备商更熟悉设备的各个部分,在网络设备优化中也有更丰富的经验,中国的设备商华为正是因为能提供优质的运维服务而广受欧洲运营商欢迎,华为的员工数量是爱立信或诺基亚的数倍,在运维服务响应方面远超爱立信和诺基亚。

面对移动通信网络复杂的状况,美国却试图将没有移动通信设备业务的Intel等糅合一起为运营商提供5G网络,这些企业本身没有移动通信设备运维经验和技术,在如此复杂环境下自然跟无法为运营商提供可靠的服务,运营商舍弃5G Open RAN设备也就在情理之中。

美国屡屡违背市场规律的图谋都是为了自己的利益,然而现实却一次又一次打脸,这说明了即使强如美国也无法违背市场和技术发展趋势,美国科技行业还是应该认清市场趋势,共同与全球各个行业合作才能真正实现共赢,否则只会一再遭受挫折。
