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.
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.
