I'm in a city center, and my small office network is currently 4G through a Samsung phone because it's faster than anything I can get on the landline. This is a city where some buildings have up to about 200Mbit/s on either cable or FTTP, but these are not available at all properties. The best landline speed I can get is "up to" 17Mbit/s downlink, which is slower than the phone, the landline uplink is ridiculously slow, and to top off the landline is more than twice the price of unlimited 4G. I'd like the speed and latency of FTTP, and failing that a good speed of VDSL over FTTP, but since I can't get either and I'm on the top floor of a 4 story building, I've wondered if Starlink would be an improvement over 4G.
