GSM data is sent in 156-bit (18 byte) frames
LTE != GSM
they produce more distortion
Only in circuits where they are driven extremely hard...or guitar amps where a tube will naturally do what takes ton of DSP
again...depends on what type of circuit you're using and if you're using the suitable tube. Stick a 6AU6 in your audio stage and it's going to get noisy.
use more power
You have me here. Thermionic Emission requires the heat.
are more fragile
Toss-Up. Drop a tube and it'll likely break depending how and what it hits. On the flipside; there are ways a transistor will fail that a tube won't care about. My tubes aren't going to care about a voltage surge or a few extra volts in the circuit. A solid state transistor will freak out if the voltage drops below a specific threshold in relation to the rest of it's voltages and will just give up during things like power surges or EMPs.
and have shorter lifetimes than solid state electronics.
Again...not entirely true. I know some tube equipment with original tubes that outlasted solid-state replacement units.
They do not sound better
You cannot measure or quantify sound quality.
