Re: 78% on FTTN, HFC, 4G speeds
In theory, sure. Let me know how that works out for you the next time it rains.
You sound a little too certain of your own convictions, and a little too interested in tooting your own horn, which in my book makes you a politician. Technical persons are generally not so interested in grand, sweeping statements that sweep important details like line quality under the rug. That's the purview of politicians leaving goose eggs for the next administration to clean up.
Also, I'm in the US, and haven't ever seen LTE top 30Mbps. Latency on wireless, even LTE, is generally in the 80ms ballpark. And as someone who uses SIP over top of his LTE connections (I've used Sprint, T-Mo, and Verizon for this), I can personally attest that this is a less than superb experience. Is the outback great for reception or something?
NOTE: I've only done this speed testing on Sprint, T-Mobile, and Verizon, and never at the same time. Most of my tests have been on Verizon, and not in super urban areas (generally cities of ~100k-250k population). I've used various devices, generally phones, to test LTE speed using the SpeedTest app from Ookla.
