Starlink provides high bandwidth plus low latency for international connections.
The low latency occurs because once the origin TCP packets reach the low orbit Starlink network, they can be almost single-hopped to the destination continent before downlinked to the user's Starlink antenna. Land based routers take 10 ms or so per hop and there are many on an international connection.<p>The White House property Wifi dead spots would be best improved separately by a commodity secured mesh network.<p>For example, Google Fiber Austin to Israel (land based router hops):
