[AusNOG] Telstra mobile down "nationwide"

Tue Feb 16 09:10:47 EST 2016

8, N, 1.  That's a start bit, 8 data bits, no parity, 1 stop bit. That's
actually 10 bits per transmitted byte.  :)

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 :)

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.

We rode on the winds of the rising storm,
 We ran to the sounds of thunder.
We danced among the lightning bolts,
 and tore the world asunder
