Difficult within the EU due to ISM limits. Maybe ok for your garden camera where the authorities just don't care. But no go for any industrial usage.

Phew, I looked it up, just by curiosity. What a nightmare :') the rules, regulations, laws are damn strict Oo

  Usually this rules are for experts who have to implement the limits. They should not be exposed to end-users.

    The problem is that the application of the rules is inherently usage-specific. For example, with the 1% duty cycle limit it is totally fine to have a transmission take 30 seconds - provided you only send 1 transmission an hour. Want to send one transmission per minute? You'll have to get your transmission time down to 0.6 seconds. And your transmission speed is inherently linked to your data rate, and by extension your signal range. There's no one-size-fits-all solution possible here. Either the user has to give it some information about their specific use case, or it'll have to stick to the absolute most pessimistic limits.

We have devices sending telemetry and occasional OTA updates without urgency (if it takes a few hours to get it over it’s not a problem). If you need consistent MB range traffic for cameras I wouldn’t advise it but for low (5kbs) traffic it can be attractive. A few thousand bits can encode quite a bit of information. Don’t be fooled by the “kbs”.

  You can do quite a lot with a few MB. Don't tell every React behemoth on the web that we know this trick.

The ETSI document actually does allow higher duty cycle if the radios take anti-interference measures. Some countries unfortunately have "harmonized" but skipped that part. Theoretically only a dumb transceiver (that can utilize only a single channel) has to limit duty cycle that low in those bands.

The EU's ISM limits are trash. Really there should be a world wide 900-1000MHz ISM band.

  Good luck trying to get the 200 ish countries governments on agreeing.

Kinda explains why starlink router doesn’t integrate it. Would be perfect for cameras around small farms.
