In Vehicle to vehicle communication, high speeds of nodes require low latency. (Latency is the time interval between sending messages by a sender node and receiving message by a receiver node.) It should be very low. To achieve the low latency requirement in Vehicle to vehicle communication, the speed of data transmission should be high. Highspeed data transmission needs high-frequency ranges.
Frequency band of IEEE 802.11p is 5,9 Ghz and frequency band of IEEE 802.11a is 5 Ghz. Why is the maximum data rate of 802.11p lower than 802.11a although 802.11p has a higher frequency band?
