My understanding is that since we are using OFDM we have to support at
least 3, 6, 12 Mb/s data rates (says 802.11-2012, Chapter 18.1.1, second
paragraph). How to choose it when transmitting? That should probably be
defined in some standard built on top of "802.11p" -- the European
"Intelligent Transport System" standard ETSI EN 302 663 defines
different channels in 5.9 Ghz band along with the "default data
rate" (Table 2, Chapter 4.3). For example Control Channel (nr. 180) has
data rate 6 Mb/s, while Service Channel 2 (nr. 178) has data rate 12
Mb/s.

Rostislav
