美国陆军战术无线电和网络通信专家
首次展示了将移动用户目标系统（MUOS）功能集成到已安装和已卸下的无线电平台的能力。
MUOS功能在陆军战术背包无线电系统变体中的实现
“在视距通信范围之外提供了更多……并利用了完全支配数据和语音频谱的能力”，
在演习中，陆军未来司令部网络跨职能小组的行动负责人罗布·赖安上校说。
The MUOS demonstration
took place during recent exercises at the Joint Readiness Training Center in Fort Polk with units from the 1st Brigade Combat Team, 82nd Airborne Division.
The MUOS
is an IT-based 3G communications protocol that replaces the legacy Ultra High-Frequency (UHF) Follow-On satellite constellation because demand for UHF services has exceeded capacity.
The MUOS is expected to deliver more than a ten-fold improvement in capacity.
Each MUOS satellite
carries a legacy payload, which is the equivalent of one UHF satellite’s capacity and capability, and the Wideband Code Division Multiple Access (WCDMA), the 3G cellular technology
that will increase available narrowband satellite communications (satcom) channels.
The MUOS also has access to
the Non-secure Internet Protocol (IP) Router Network (NIPRNet),
the Secure Internet Protocol Router Network (SIPRNet),
the Defense Switched Network (DSN),
and enables communication between itself and 3G WCDMA,
as well as legacy systems from an end-to-end perspective.
