Capacity is the revenue ceiling. On March 22, 2022, Space Exploration Technologies was granted US11283666B1, “Stochastic digital pre-distortion compensation in a wireless communications system,” classified in H04L 27/367, the signal-linearization art. SpaceX is private — no 10-K — so the moat reads through the patent record.

A satellite-broadband network earns money by delivering bits to subscribers, and the number of bits it can deliver is bounded by two scarce resources: physics and licensed spectrum. Power amplifiers distort the signal when pushed hard, which forces operators to back them off — wasting capacity. Digital pre-distortion compensates for that distortion in software, letting the amplifiers run harder and cleaner, which means more usable throughput per unit of spectrum.

“A wireless communications system includes a stochastic pre-distortion actuator configured to receive a carrier-modulated signal and convert the carrier-modulated signal into an output signal.”— U.S. Patent No. 11,283,666 source

For an analyst, that maps to the top line. In a constellation already built and launched, capacity per satellite is largely fixed by the hardware — except where signal processing can wring more out of it. Spectrum-efficiency gains are nearly pure margin: they raise the sellable capacity of an asset that is already paid for. Across millions of subscribers, a few percent more throughput per beam is a meaningful revenue lever with no new capex.

The caveat this desk keeps: signal-processing patents are incremental and surrounded by prior art, and one claim does not define a network's capacity. The gain is real but bounded and hard to attribute precisely.

Still, the patent points where the marginal revenue lives. Once a broadband constellation is in orbit, growth comes from getting more paying bits through the same spectrum — and a pre-distortion patent is a claim on exactly that efficiency.
