Title: SYSTEMS AND METHODS FOR SEGMENTATION AND REASSEMBLY OF DATA FRAMES IN 802.11 WIRELESS LOCAL AREA NETWORKS
Abstract:
Embodiments described herein provide a method for fragmenting and reassembling data frames on a medium access control (MAC) layer in a wireless local area network. A datagram is received from an application running on a first network device, for transmission over a wireless communication link in the wireless local area network. A negotiation request is initiated with a second network device for determining whether both the first network device and the second network device have enhanced directional multi-gigabit capability (EMDG) for data segmentation and reassembly. When both devices have EMDG capability and the size of the datagram exceeds the maximum size defined by the wireless local area network transmission protocol, the datagram is segmented into a plurality of transmission data units on the MAC layer.
