WIRELESS TRANSMISSION APPARATUS AND MAC FRAME TRANSMISSION METHOD Russian patent published in 2013 - IPC H04W28/10 

FIELD: radio engineering, communication.

SUBSTANCE: transmission device, which serves as a layer-2 switch (L2SW) or router, includes a MAC frame transmission device and a radio transmission device with an adaptive modulation function, which switches radio transmission capacity in response to fluctuations of quality of radio transmission lines. The radio transmission device determines a modulation method based on reception power of a reception signal transmitted from the radio counterpart station, wherein the modulation method is multiplexed with a PAUSE frame, which is then sent to the MAC frame transmission device. The MAC frame transmission device detects a current radio transmission capacity from the PAUSE frame, selects QoS setting suited to the radio transmission capacity from among a plurality of QoS settings, and performs a control operation based on the selected QoS setting with respect to a LAN signal from the user network. The radio transmission device modulates and transmits the LAN signal to a radio counterpart station.

EFFECT: providing dynamic change in capacity.
