图片来源:EchoStar。 一切要从T-Mobile收购Sprint说起 2019年当时,Verizon、AT&T、Sprint和T-Mobile构成了美国四大全国性移动运营商的市场格局。在T-Mobile和 Sprint开始合并交易后,美国司 法部要求另一家公司填补空缺出来的"四大"缺口,从而保持一定的移动市场竞争性。 这时,有线电视运营商Dish Network从Sprint手中收购了Boost Mobile(移动服务预付费品牌)以及部分无线频谱——合并交易通过监管批准的 要求之一是必须剥离一定的移动业务资产,由此开启了美国新的Top 4移动网络运营商的发展之旅。 C114讯 8月29日专稿(艾斯)随着EchoStar作价230亿美元向AT&T出售其3.45 GHz和600 MHz中低频段频谱资源,美国市场培育第四家大型移 动网络运营商的梦想基本宣告破灭。 同时,这对Open RAN生态系统来说也意味着一次沉重的打击。因为伴随频谱牌照的易手,全球规模最大的Open RAN网络基础设施之一将面 临关闭,Dish的多年投入几乎"付之一炬"。 那么,从被寄望于成为新的美国Top 4全国性移动运营商,到被迫通过 ...

中美5G路径分野——中国领跑生态制胜vs美国Open RAN困局难解

"Open RAN" 测试结果揭示美国路线陷入困局 近日,美国国家电信和信息管理局(NTIA)公布了为期两年的"Open RAN"测试结果显示,Open RAN技术虽已跨越早期阶段,但要达到与传统单一供应商 方案同等成熟度仍需时日。 NTIA的测试报告用一组数据勾勒出开放RAN的现状:其中有四家供应商成功实现了跨厂商设备组网——通过Xn接口完成不同厂家O-CU、O-DU与O-RU的 互联互通,并实现N2/Xn接口的呼叫切换。这说明开放RAN接口技术取得实质性的突破,但报告同时指出:相比单一厂商方案,开放RAN的软件成熟度仍存 在明显差距,特别是在网络优化所需的AI/ML算法升级方面。 【环球网科技报道 记者 张阳】2025年5月17日,是世界电信和信息社会日,也恰逢国际电信联盟(ITU)成立160周年,今年世界电信和信息社会日的主题 为"在数字化转型中实现性别平等(Gender equality in digital transformation)",凸显了国际电信联盟致力于通过ICT技术推动性别平等、促进社会公正,让数 字红利惠及每一人。 从1865年到2025年,160年的时间里,通信技术从电报、电话,演 ...
