"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 ...
