Don't forget Ethernet uses 8b10b encoding on top of the frame

LTE supports up to 64QAM (256QAM for LTE Advanced) for the actual
radio side of things<br>
This (rather cool) page has all the nitty gritty details:<br>

<div>Since it's sent over packet radio, I was figuring it was
basically the same overheads. If you happen to have
references on how the data on LTE is encapsulated, I'd love to
read them :)</div>
<div><br>
</div>
<div>If it was ethernet, the overheads are much narrower - 38
bytes for the Ethernet frame, and 40 bytes for the IP header.
(Though the IP header isn't going to be taken into account by
Layer 7 apps reporting their throughput), or only 5% of
throughput, compared to 20% on serial.</div>

<p dir="ltr">The more interesting question is when did you
start using 10 bits per byte, and why did you think it was
common or popular to use?</p>
<p dir="ltr">The only way I can think of to get to 10 bits
per byte is on an async serial link with combinations of
non-zero numbers of parity and stop bits, and that wasn't
common in my time dealing with dealing with serial. N, 8,
1 was or 9 bits in total.</p>
