DSA - Khan BMS Battlefield Management System
Working notes on DSA (Dynamic Spectrum Access): ew mesh context, design trade-offs, and where it fits in the Arban–Tumen hierarchy.
A jammed forward node, a half-readable track, a window measured in seconds — that is where DSA earns its keep. Dynamic Spectrum Access is not a slide-deck capability; it is the seam where doctrine meets a contested radio.
Dynamic Spectrum Access — DSA for short — covers real-time, opportunistic use of spectrum based on sensing and policy. Dynamic Spectrum Access is the operational pattern in which radios share spectrum by sensing occupancy and policy and transmitting only on currently available channels. DSA is essential for coalition operations, congested environments, and EW conditions where fixed frequency assignments cannot be trusted. It is implemented as a cognitive-radio control loop bound to a spectrum policy engine.
DSA earns its full keep at the Tumen — ten thousand nodes under a single human Khan. Span of control stays at ten because the hierarchy is fractal; DSA state aggregates upward through Minghan and Zuun before it ever reaches the Khan's console.
When the dust settles on the next contingency, the platforms that handled DSA as a design assumption will be the ones still in the fight. That is the bet.
