联通航美卫星 + 4G 产品验收成功

3 月 3 日消息，据联通航美发布，近期，联通航美网络有限公司在北京上庄卫星中心对卫星 + 4G 基站产品进行功能验收，取得圆满成功！

据介绍，该套产品组网便捷、即插即用、灵活部署，在 2 分钟之内即可完成开通。4G 基站与卫星便携站通过网线连接，利用卫星链路接入联通核心网，可支持 32 名用户同时接入 4G 网络，实现 4G 网络的精准覆盖。卫星 + 4G 基站产品充分发挥卫星通信覆盖面广、不受地域影响等优势，可为地面网络覆盖不到的边远地区以及空中、海上用户提供正常通话和上网功能。

联通航美 4G 基站产品采用基带和射频一体化设计，搭配卫星便携站，通过卫星链路接入联通核心网，为用户提供 4G 网络。

测试现场手机接入基站 4G 网络后进行业务验证，与公网 4G 手机拨打 VOLTE 语音通话并开启视频，实现卫星网与公网 4G 相互通信，通话过程中画面清晰流畅，与公共 4G 网络间通话无任何差异。
