Both radio services – WiFi based on 802.11ac and 5.9GHz DSRC based on
802.11p use Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA)
strategies to determine which transmitter will have access to the
Given that 5.9GHz DSRC devices will be configured to use 10MHz channels
while 802.11ac devices will be configured to use 20, 40, 80 or 160MHz
channels, will 802.11ac devices be able to detect the presence of
802.11p transmitters so that only one transmitter will attempt to use
the medium at a time?
As licensed devices, 5.9GHz DSRC devices have priority access to the
Given that both types of devices will be able to detect the presence of
each other, will 802.11ac devices be able to determine that the other
transmitter present is an 802.11p device so that it can defer to the
device with priority?
