6G 研发正式走出实验室。Verizon 与爱立信近日宣布，双方在美国加州康科德的一个 Verizon 商用网络站点完成了业界首个 7GHz 频段的准标准（pre-standard）6G 外场呼叫。此前业界在该频段的验证大多停留在实验室环境，此次将测试直接搬到真实商用站点，标志着 6G 从理论研究向工程化落地迈出实质性一步，也为全球 6G 标准制定提供了第一手外场数据。
从实验室到商用站点：7GHz 频段的真实考验
本次测试采用爱立信的 6G 概念验证套件，聚焦上中频段（upper mid-band）在室外环境下的实际表现。7GHz 频段被视为 6G 候选黄金频段之一，既能提供比毫米波更优的覆盖能力，又保有数百兆赫级的连续大带宽，但其传播特性，尤其是建筑穿透能力，此前缺乏充分的野外数据支撑。
测试架构颇具巧思。基站在站点机房上方部署，用户终端则安置在一个 12×8 英尺（约 3.7×2.4 米）的移动测试舱内。该舱体配备了定制化电源备份系统，并可灵活更换不同材质的玻璃与墙体材料，支持固定式室外和室内两种无线配置。通过与机房保持一定距离摆放，工程团队能够系统性地评估 400MHz 载波的准标准 6G 协议栈在视距、非视距路径、植被遮挡、物理障碍物以及建筑入损（building entry loss）等复杂场景下的真实表现。
【关键数据】
- 测试频段: 7GHz 上中频段（6G 候选核心频段）
- 载波带宽: 400MHz
- 测试地点: 美国加州康科德 Verizon 商用站点
- 移动测试单元尺寸: 12×8 英尺（约 3.7×2.4 米）
- 评估维度: 覆盖、吞吐量、时延、稳定性、特性性能（全维度外场实测）
信号穿墙实测：为 6G 标准积累话语权
目前双方已成功验证室外呼叫，测试重心正转向 6G 信号从开放空间进入建筑物内部的传播特性——这正是中频段能否支撑广域覆盖的关键命题。整套测试覆盖覆盖范围、吞吐量、时延、稳定性及特性性能五大维度，全部在真实网络条件下完成，数据的工程参考价值远超暗室仿真。
Verizon CTO 兼技术发展高级副总裁 Yago Tenorio 表示，爱立信在其 6G 创新论坛（6G Innovation Forum）中扮演关键角色，双方正合力推动 6G 研究成果向实际部署转化。他强调，此次外场试验产生的技术洞察，将直接影响全球标准的塑造，并为未来网络的设计与部署提供指引。
标准卡位战：外场数据成为谈判筹码
从产业竞争视角看，此次测试的时点选择颇有深意。3GPP 已启动 6G 标准研究工作，预计 2025 年至 2029 年将进入标准定义与细化阶段，谁能在关键候选频段上掌握真实外场数据，谁就能在标准提案中占据主动。Verizon 此前已联合多家设备商成立 6G 创新论坛，此次与爱立信的率先外场验证，明显是提前卡位。
北美运营商在 5G 时代因中频段布局领先而获益颇丰，6G 周期中这一策略正在重演。7GHz 频段有望在即将举行的世界无线电通信大会（WRC）上被确定为 6G 全球统一频段候选，Verizon 与爱立信的实测数据将为这一进程提供有力佐证。从长期看，外场验证的节奏快慢，将直接决定各家在未来 6G 标准组织中的话语权分配，这场围绕 7GHz 的卡位战才刚刚开始。

英文原文Verizon and Ericsson claimed the first pre-standard 6G field call in the 7GHz range, moving their testing from the laboratory to a commercial network site. The call was conducted at a Verizon commercial site in Concord, California, using an Ericsson 6G proof-of-concept kit. The companies tested upper mid-band frequencies outdoors and measured how the signals penetrated a building. The test used a base station installed on a site shelter and user equipment housed in a 12-by-8-foot mobile enclosure capable of supporting stationary outdoor and indoor radio configurations. Positioned away from the site shelter housing the base station, the mobile test unit features custom power backups, varied glass and wall material configurations. The setup allows engineers to measure how a pre-standard 6G stack operating over a 400MHz carrier handles line-of-sight and non-line-of-sight paths, foliage, physical obstacles, and building entry loss. The companies verified an outdoor call and are also testing how 6G signals travel from open-air environments into buildings. The work measures coverage, throughput, latency, stability and feature performance in real-world conditions. Verizon CTO and SVP of technology development Yago Tenorio stated Ericsson plays a key role in the operator’s 6G Innovation Forum and its efforts to turn 6G research into practical deployments. He added the outdoor trial would provide technical insights to help shape global standards and guide the design and deployment of future networks.
