Dish says SpaceX has been lying to customers about how a plan to
expand the use of certain airwaves for 5G could disrupt its Starlink internet-from-space service. SpaceX sent a "manipulated filing" to the Federal Communications Commission in an attempt to prove the expanded
5G usage would lead to substantial interference, writes Dish and a
group of other companies known as the 5G for 12 GHz Coalition. They
write that SpaceX is conducting "a public misinformation campaign"
against 5G.
"This tactic, which is commonly used by Elon Musk, is not only
disingenuous, but it promulgates an anti-5G narrative that is harmful
to American consumers who deserve greater competition, connectivity
options and innovation," the Coalition writes in a statement published
today.

I trust Elon Musk not as far as I can throw him, but still perhaps more
than one can trust Charlie Ergen.
The 12 GHz band is used for satellite downlinks. Thus the receivers
have to pick up signals from thousands or hundreds of miles
away. These include signals from GEOsats like, uh, Dish, and LEOsats
like Starlink. The satellite TV business is apparently not as
profitable as the mobile phone business, so Charlie is willing to
sacrifice it in order to get free mobile spectrum, which nowadays is a financial instrument worth more in trade than in use. That is his
usual business plan -- buy up licenses that are for limited, low-power
use and beg the FCC to change them to higher-power, more valuable
licenses. Nice work if you can get it. He's doing the same thing on
the 3.5 GHz CBRS band, where they bought a bunch of Priority Access
Licenses with a 47 dBm/10 MHz power limit and are asking to raise the
power limit by a factor of more than 100, which of course would
disrupt other users of the band.
The idea that a satellite downlink won't be interfered with by a
mobile phone passing in front of it is, well, ridiculous on its
face. Charlie's main excuse seems to be that Starlink is also allowed
to use higher-frequency bands, which are more subject to rain fade, so
they shouldn't care if 12 GHz is interfered with. Yeah, right.
