<h2><strong>多方协同，促成创新落地</strong></h2> </div> <p>本次试飞任务的成功，汇聚了上级部门的深切关怀以及各参与方的不懈努力。在广东省委的统一指挥与调度下，广东省应急厅、通信管理局、广播电视局等主管部门积极协调，中国广电（中广电移动）科学指导，广东移动全力配合，广东广电网络公司不遗余力推进项目，组织精干团队进行技术攻关，确保了此次5G+700MHz在应急通信领域创新应用任务的圆满成功。这一里程碑式的成就，为我国应急通信领域的发展注入了强劲动力，同时也彰显了广电行业的实力与担当。</p>

<h2><strong>5G+700MHz，凸显强大优势</strong></h2> </div> <p>中国广电的700MHz频段堪称通信“黄金频段”。无人机飞行测试过程中，其它频段偶现信号不佳甚至中断，广电5G 700MHz却始终保持语音和短信业务畅通，700MHz频段覆盖广、穿透力强的优势彰显无疑。同时，广电5G 700MHz频段组网成本极具性价比，能在复杂环境实现广泛稳定覆盖，为通信服务及行业数字化赋能优势突出，推动通信资源高效利用。</p> <div> <h2><strong>以点带面，赋能全国应急通信保障体系</strong></h2> </div> <p>此次5G+700MHz无人机在广东试飞成功，对全国应急通信保障体系有重要参考价值。面对自然灾害、事故灾难等突发情况，地面通信网络易遭“三断”破坏致联络中断，影响救援。应急通信无人机凭借机动性，能快速实现救援指挥中心与各方通信顺畅，为救援争取宝贵时间。但由于常规频段覆盖能力有限，救援面积受到一定限制。如今借助广电5G 700MHz的无人机，可快速实现更广域的应急通信覆盖，让受灾群众能及时与外界联系，提升我国应急通信保障体系的全面性与及时性，守护社会稳定与人民福祉。</p> <p>此次试飞成功，展现出中国广电在应急通信领域的深厚技术积淀与创新能力。未来，广东广电网络将以此次为契机，持续加大5G技术研发与应急通信投入，拓展广电5G在应急场景的应用，推动应急通信行业高质量发展，筑牢国家应急通信保障体系，为国家发展贡献力量。</p> </div> <div class="Qr-code"> <span class="like"> <a title="喜欢就赞一个！"
