In the wireless properties, there are many modes that can be
used as needed. Wireless mode function to determine whether to enable the
access point (transmitter), repeater, or enable the station (receiver). There
are several modes that have almost the same function, call it eg station-bridge
mode with station-pseudobridge. Now we will try to do testing mode selection
effect on the throughput of data that is passed. Testing using standard band
802.11 B / G / N.
Access Point
There are only two modes that make interface works as a
wireless access point. AP-Bridge topology PTMP (point to multi-point) where
there are many clients are connected, and topology Bridge mode to PTP (point to
point) where there is only one client is served. At this testing time, same
station side - the same uses station-bridge mode.
From the results of testing there was no significant
difference in throughput. When used to handle one client, throughput both still
balanced, between 150Mbs up to 200Mbps up and
down. This is normal, especially
when the client amounted to more than one. Interference and client positions
also affect throughput.
Station
Now we will try to do a test throughput access point side of
the station where the same - the same use Bridge mode, in this case using
topology Point to Point.
From the results of testing, there is no change in
throughput on a station-bridge mode, station-pseudobridge, and WDS station,
each - each can achieve the throughput of 200Mbps. Next we try testing
performance wds-slave mode and station-pseudobridge-clone.
However there was a significant decrease in throughput at
the station mode-pseudobridge-clone and wds-slave. On-station mode
pseudobridge-clone throughput that can be passed around 100Mbps, almost half of
the station the previous mode.
A significant decrease also occurred in wds-slave mode where
throughput is passed only about 100Mbps with 2 client laptop was connected as a
client and a second repeater with WDS Slave mode. Reduction in throughput at
wds-slave mode can actually be said to be reasonable because the wireless
interface has to work twice, received the signal and then radiates it back.
Results of testing here may differ from the test that you
may do yourself. Depending on the conditions of environmental and obstruction,
interference, the quality of the wireless link, and the device used.
