Air National Guard communications units need a capability that diversifies connectivity to SECRET Internet Protocol Router Network (SIPRNET) with command and control elements using regional, beyond line-of-sight microwave communications technology in environments where satellite communications signals are obstructed, impaired, or denied. The current AN/TRC-170 tropospheric scatter system is outdated and no longer fully supported. The proposed next-generation tropospheric system leverages significant advancements in technology, utilizing Everything Over Internet Protocol as its baseband interface and offers and aggregate data rate up to 50 Mbps (a six-fold improvement). Additionally, separation of antennae in both space and operating frequencies, or space and polarization, produces lower bit rate errors, increasing the nominal signal range. This mitigates or reduces network congestion and preserves quality of service. Logistically, the next-generation system reduces the air deployable cargo footprint from six pallets down to one. The lack of diversified transmission capabilities for both domestic and overseas missions impairs command and control networks when satellite systems operate in a contested environment.
