One thing to note is that the frequency bands specified only apply to US 5G. Huawei's 5G spectrum uses a much lower frequencies: Around 3.8GHz. This falls in the mid-range spectrum, which makes it cheaper to deploy, because the waves travel further and you need fewer towers. That is the attraction of Huawei, for most countries (outside of the US).

Also interferes with a lot of hospital devices that operate in that freq range. It’s a fight I am casually observing from the sidelines with popcorn.

  Isn't the ISM bands at 2.4 and 5.8 GHz? That shouldn't be interfered by 3.8 GHz 5G signals. Is it because of out-of-band intermodulation from 5G signals or because there are parts of the 3.8 GHz spectrum used by medical devices not for wireless networking but for sensing/measurements?

  Wifi has been around a long time now. Why can't the hospital devices just use that like everyone else? (Oh except wireless microphones in churches, which are also some special snowflake exceptions for some reason...)

    Because everything interferes with WiFi. It’s junk spectrum. You don’t want critical, lifesaving devices operating on the same spectrum as the microwave in the break room.

      "Critical, lifesaving" functionality is for the most part hardwired. Some devices use radio over extremely short range (think arm's length), but any radio communications over longer distances are for reporting or something else non-critical.

The US FCC gave half of C-band to mobile telcos and told the incumbent satellite users to switch to HEVC to make up the difference. https://www.fcc.gov/document/fcc-expands-flexible-use-c-band-5g https://www.fcc.gov/document/fcc-expands-flexible-use-c-band... "Makes 280 Megahertz of the 3.7-4.2 GHz Band Available for 5G Services While Relocating Existing Satellite Operations to the Upper Part of the Band" The millimeter wave stuff is in addition to this for downtown cores, stadiums, etc. 5G modulation itself adds max 15-20% throughput compared to 4G LTE so more spectrum is needed to deliver on the weird promises telcos made.

This doesn't make a lot of sense.. There is no "Huawei 5G spectrum". Huawei equipment has to operate in whatever spectrum regulations exist for the country buying the equipment. Countries (including parts of the US) buy Huawei gear because it's cheap, not because there's any special spectrum benefits.
