binding or not, thus, these elements which influence
throughput combined will generate multiple physical
rates for you choices. MCS can be interpreted as the
complete combination of the elements which influence
the rate. Each combination is uniquely marked with an
integer.

Aggregation MSDU: Aggregates multi-MSDU to
become a bigger load. The MSDU can be considered
as an Ethernet Message. Usually when AP or wireless
client receives the message (MSDU) from the protocol
station, they would mark it with Ethernet Head, which
is called A-MSDU Sub-frame. However, it needs to be
converted to 802.11 message format before being
sent out through RF port. And A-MSDU technology
aims to aggregate several A-MSDU Sub-frames and
send out by encapsulating them into an
802.11message.Thus, it reduces the occupied bits of
PLCP Preamble, PLCP Header and 802.11MAC which
are required to send an 802.11message.Besides, the
amount of response frame is decreased and the
message sending rate is improved.
