Analyze WiFi packet traffic via command line
A device that uses 802.11n high throughput (HT) mode -- also known as Greenfield mode -- assumes that there are no 802.11a/b/g stations using the same channel. 802.11a/b/g devices cannot communicate with a Greenfield AP. Instead, their transmissions are likely to collide, causing errors and retransmissions for both parties. Normally, 802.11 devices share channels by sensing when another device is transmitting, using a back-off timer to wait until the channel is free. However, because an 802.11a/b/g device cannot tell that a Greenfield device is transmitting, it will go right ahead and transmit. To avoid this, the 802.11n standard also defines an HT mixed mode. |
