Technology is changing all the time and what was the 'Industry Standard' yesterday may not apply today.
With my limited knowledge I didnt think that the signal from a Satellite 'Up There' could be 'spot' beamed to an area less than Continent but apparently it can.
I watch the Cycling and its hugely apparent with Digital how it demands the best possible signal path otherwise its a scrambled mess so based on that, its easy to see where communications are critical, getting the best EIRP levels are essential and having a map would assist you to achieve this.
10 years ago it was all one way, ie from a few Ground stations to the Satellite which then broadcast back to the customers home but today, how many like me actually have an UP Link (Internet) to the Satellite from their home, quite a few now.
