Fig. 1From: N-DCF: MAC overhead reduction using narrow channel contention in wireless networksAverage transmission time for a 160 MHz channel and a 20 MHz channel. The packet size is 1500 bytes. For MCS index 7 and short guard interval, the data rate for 20 MHz is 72.2 Mbps, while the data rate for 160 MHz is 650 Mbps. Although the data rate of a 160 MHz channel is nine times the data rate of a 20 MHz channel, the time for transmitting a packet is not significantly differentBack to article page
