My past set of 11g-only checks mixes the two situations by working the streaming script on the Broadcom-based mostly WLAN as well as throughput script around the Atheros-based.
You almost certainly would hardly ever recognize interference between two 11g WLANs operating online video streams at any distance.
This time each the throughput and Missing Information plots are really worth demonstrating, simply because you can Plainly see differences in both equally.
Considering that among the two WLANs had to move to check at different distances, and since I've only two notebooks, I applied them the two within the Tremendous-G 50 % of my check rig for making points easy to maneuver all-around.
This enables me for getting again up with no help. It is very superior quality and 50 % the price of competitors. Now we have loved our Superhandy scooters for the last 12 months (terrific about the cruise ship!) and understood this machine could well be equally as fantastic!
Atheros introduced its Super-G throughput improvement technological know-how back again in April of this 12 months, nevertheless it’s taken until eventually now for solutions to hit the shelves.

Mainly because this test makes use of many of the bandwidth that each WLAN has to give, the spectrum created by Just about every WLAN are going to be greatest width, leading to a worst-scenario channel overlap and worst-circumstance interference circumstance.
Chariot doesn’t incorporate MPEG streams among its take a look at scripts. So I had for making do utilizing the NetMtgv.scr script, which emulates a NetMeeting 2.1 Video stream. I utilised UDP as the protocol and set the stream level to 2.048Mbps.
Neither is Super-G’s “speedy frames” feature – which inserts several information packets into one information frame – because it’s also Section of the 802.
The timing appeared to be 45 seconds of Super-G and 15 seconds of 11g within the NETGEAR BETA dynamic Super-G updates that I used. A special implementation of dynamic Super-G in D-Connection Tremendous-G enabled gear used by Broadcom in its screening confirmed the timing being 120 seconds of Super-G and seventy five seconds of 11g. So it appears like Atheros, NETGEAR, or both equally are doing some general performance tuning.
And although it’s accurate that two 11g WLANs can interfere with each other as Atheros contends, it’s superg168 only when equally are functioning comprehensive-tilt, and perhaps then, the interference is gone by the point the WLANs are divided by thirty ft – nicely in need of the 100 ft that Atheros continues to be quoted as indicating would be the 11g interference zone.
The yellow shaded space signifies the power from channel 2’s signal that overlaps into channel one’s primary lobe (the biggest “hump” in addition to the frequency band which contains almost all of the sign’s power).
The outcomes display 0.041% of knowledge was misplaced while in the Broadcom-based mostly stream and none inside the Atheros-based mostly stream. This isn’t really incredibly major, Primarily given that the most important disturbance is thanks the glitch because of the Broadcom driver.
