Three satellite eras

Dramatic increases in the number of two-way satellite terminals is a key issue in current spectrum policy, e.g. the argument between satellite and cellular interests in the millimeter wave bands. Most Earth stations used to be TV receivers. However, the growth of satellite broadband service is increasing the number of Earth station transmitters.While it's an over-simplification, but it helps me to think of the number of earth station transmitters (often referred to as uplinks) growing in three overlapping and cumulative eras.

Satellite spectrum efficiency

I’m no fan of the concept of spectrum efficiency, but it’s helping me understand the gulf between the cellular and satellite businesses.

Economic rivalry, interference and spectrum allocation

I’m intrigued by the questions:
  • What is the relationship (if any) between rivalry and licensing regime in spectrum regulations to date? 
  • And what should it be in the future? 
 I think such work could shed light on efforts to allocate and assign millimeter-wave spectrum (roughly, above 30 GHz).

Scale change and regulatory change

The current and forecast growth in the number of satellite systems is putting strain on how the FCC and other agencies regulate satellites. There’s a lot of talk of regulatory reform, and calls for comprehensive rather than incremental change.

That leads me to wonder: are there instructive precedents where a step change in the scale of an industry or activity forced a complete restructuring of regulation; or conversely, where change in regulation let to a change of scale?  Perhaps there are examples where one might take lessons for the reform of space governance.
