I think that spectrum may be in high demand in the near future - all those holdings in the 2000-3500 MHz range are perfect for building out fixed wireless 5G. Low enough frequency to travel far enough to allow standard sized cells and they should have enough spectrum to cover them. Most towers in mid/large sized cities are rented not owned so a company just needs to pay someone to install antennas in the markets they want to cherry pick. Maybe Ergen is planning to have Dish do this itself and convert into a wireless internet company, who knows.
As you reference, Dish's spectrum holdings are low-band and mid-band, not the millimeter wave high-band stuff that will primarily be used for super-fast (1 gig plus) 5G. And the big wireless players, especially Verizon and AT&T, are pretty well stocked up on low-to-mid-band spectrum, which is why the bidding wasn't as aggressive as expected in the last FCC auction, when Dish stocked up on some more of that spectrum at relatively low prices. Furthermore, as CBRS and TV white space frequencies open up, and carriers also continue to exploit wifi frequencies with LTE-U, that will further ease any need to buy more spectrum licenses.
Once fixed wireless 5G starts covering most rural areas, leaving only the REALLY rural areas (all the areas with the best dark sky viewing on the dark sky maps, basically) there won't be enough customers left to support something like this. I just don't see satellite internet (LEO or otherwise) as financially viable once wired or cellular internet is an option for 99.999% of the US population, even if that totals only 80% of the landmass.
So, what do you mean when you talk about fixed 5G covering rural areas? Because millimeter wave 5G -- which is what most of the hubbub is about -- won't ever broadly cover rural areas since it only travels short distances. I suppose you're referring to the type of 5G that T-Mobile plans to roll out over their low-band 600 MHz spectrum, which can travel quite far and serve huge rural areas. But at that frequency, the speeds will be much lower than at millimeter wave frequencies, although it's somehow technically still 5G and so, I guess, offers somewhat more bandwidth than regular LTE would on that same 600 MHz. (T-Mo is already lighting up 600 MHz in many areas with LTE and say they can switch those radios over to 5G with just a firmware update.)
T-Mobile has stated that they will for sure offer fixed wireless home internet to rural dwellers on their new 600 MHz spectrum soon. (In fact, that's part of their pitch to the feds to gain approval for their merger.) Should they be allowed to merge with Sprint, their total spectrum holdings would definitely exceed both Verizon and AT&T. So, as
this article explains, that could put pressure on those two companies to buy some of Dish's spectrum, to play catch-up. But then the merger may be blocked or the combined T-Mobile/Sprint may be forced to sell off some of their combined spectrum to Verizon and AT&T as a condition of the merger to even the playing field. In either of those latter two scenarios, Dish would still be sitting with a bunch of spectrum that no one much cares to buy. Obviously, Ergen is hoping that the government allows the T-Mo/Sprint merger to sail through with no real conditions attached. I'm not sure that's in the cards, but who knows.
Assuming that Verizon and/or AT&T began competing with T-Mobile in the early 2020s to offer nearly-nationwide wireless home broadband service at pricing that matches what we typically see in metro areas from competing landline providers, then yes, LEO satellite internet would have a hard time gaining enough customers to be a sustainable business. But in that scenario, we're talking about rural Americans gaining widespread access to affordable broadband even
sooner than would be the case with LEO satellite internet service. Which means that DBS will be doomed even sooner than I was anticipating before (at 2028). Because once folks have reliable broadband with high or no data caps, and AT&T is offering them virtually the same service OTT as via DBS, but at a lower monthly rate, why wouldn't they switch? Or switch to one of the other OTT vMVPDs? Or switch to a combo of on-demand OTT services such as Netflix, Hulu, Disneyflix, etc?
Again, rural dwellers without access to affordable, reliable broadband service will be the last bastion for DBS. AT&T knows that and has stated it. But once that rural digital divide is closed -- around, say, 2023-26 -- that's when DBS will truly become a rare things that survives only because of the ingrained habits of mostly elderly folks who don't want to switch it out for something better and cheaper because they dislike change. But it's hard to keep a large-scale operation afloat serving just that demographic, I'd think.
