training symbol(LTS).
STS using for signal detection, freq. offset estimation, and AGC has 10 symbols
of 0.8us each.
LTS using for channel estimation has 2 symbols of 3.2us + 1.6us guard interval.

Subject: 802.11a preamble
Hello,
I'm reading 802.11a specs and trying to understand how long in microseconds is
the 802.11a preamble.
I know that 802.11a preamble is 12 symbols long plus one symbol for SIGNAL. But
how can I convert it to time?
I need to know how many data (counted in time) are added to 802.11 frame to be
ready to transmit by hardware.
