What is the use of Order bit in IEEE 802.11?

[M/Q]

Not sure if this is the explanation you want.

But when a wireless network is in infrastructure mode. The traffic-indication virtual bitmap, maintained by the AP that generates a TIM, consists of 2008 bits, and is organization into 251 octets such that bit number N (0 ≤ N ≤ 2007) in the bitmap corresponds to bit number (N mod 8) in octet number [N / 8] where the low-order bit of each octet is bit number 0, and the high order bit is bit number 7. Each bit in the traffic-indication virtual bitamp corresponds to traffic buffered for a specific station within the BSS that the AP is prepared to deliver at the time the beacon frames is transmitted.

Bit number N is 0 if there are no directed frames buffered for the station whose Association ID is N. If any directed frames for that station are buffered and the AP is prepared to deliver them, bit number N in the traffic-indication virtual bitmap is 1.
