Signal strength and channel bandwidth are only partially related.
You could blast out a 100Hz-BW CW signal at 1MW, but you will not be able to send much on it, even if you can receive it from the Moon.
There are other limits too, like channel concurrency, which you can see in action in places like busy stations or stadia where your phone can't connect and your Bluetooth headphones become unreliable. I don't know how many simultaneous connections a single Starlink transceiver can handle, though.

- adhesive_wombat 5y agoYes, but that is presumably not a maximum of 18 billion users at 1 bps, nor a maximum of 1 user at 18Gbps.
- adgjlsfhk1 5y agobased on the plans they are selling, it almost certainly can do both 40 users at 500mbps and 200 users at 100mbps. This is a total guess, but I'd imagine it can probably do 2000 users at 10mpbs, since 10:1 over-subscription is pretty common for ISPs.
