However, the network state determined by the above-described evaluation method cannot comprehensively and accurately reflect the actual quality state of the network.

The embodiment of the application firstly provides a network state determining method applied to AC equipment. Fig. 1 is a flowchart of a network status determining method applied to an AC device according to an embodiment of the present application, where, as shown in fig. 1, the method may include the following steps:

The a-MSDU is similar to the a-MPDU and is used to pack and transmit a plurality of service data units (SERVICE DATA units, SDUs) into one larger aggregation Unit, thereby enabling to improve transmission efficiency while reducing the overhead of radio frames.
