Table 4 Channel Width
We canenablemultiple fields bysettingrate flags value appropriately.
S
et Aggregationflags:
Thisflagis
for enabling ordisabling aggregation support .Higher length packets can be trans
mitted
by enabling aggregation flag.If thisflagisset then it enables the TX aggregation. User can give
maximum oflength less than or equal to 30000bytes whenthe aggregation is enabled. This m
aximum
supported length mayvary dependingonthe available buffers
in
TA. User given length isdivided
into
chunks of size 1792 bytes.All these chunks are aggregated and
sent.
If this flag is not set then aggregation is not enabled
and packetswillbe sent without anyaggregation, Andmaximum length that
canbe
sent inthis case is 1536bytes Aggregation feature is supported only in burstmode. This
filed will be ignored in case of continuous mode.
S
et Number of packetsto send:
Thisfield
is used tosetthe number of packets to be sent in burst mode. If the value given is ‘n ’
then ‘n ’number of packetswill be sent on air, afterthat transmission
willbestopped.
If thisfieldis givenas ‘ zero ’then
packets will be sent continuously until user stopsthe transmissionusing transmit utility.
Thisfiledwill be ignored in case ofcontinuous mode.
S
et Delay between thepackets:
Thisfieldis used tosetthe delay between the packets in burst mode. Delayshould
be
given inmicroseconds.i.e. if the valueis given as ‘n ’ then a
delayof
‘n ’ micro seconds willbe added for every transmitted packet in the burst mode.
If thisfield is set to ‘ zero ’ then packets will be sent continuously withoutany delay.
Thisfiledwill be ignored in case of continuousmode.
