@ Thx, I focus at LTE stuff at forum as nick: SiB.
This topic is very important.

[@sliddjur]

10:30 can someone explain how it is exactly 64 bytes? is it 64 bytes - ethernet overhead = 18 bytes, minus ip+udp header -28 bytes... now we have 64-28-18 = 18 bytes udp-payload data? also, he wrongly calls it layer2 "packet" and not frame? =)
