The amount of overlap amongst the traditional 11g and Tremendous-G alerts would've additional Evidently illustrated if all had been plotted at exactly the same length so that every one peak signal stages had been equivalent, but This really is what Atheros provided.
The ink had barely dried on the 802.11g conventional when wi-fi chip brands began to roll out non-regular throughput “improvement” systems.
This time both equally the throughput and Lost Knowledge plots are truly worth displaying, as you can Evidently see variations in both.
Something else is hitting the ,er, lover, although, in the form of a controversy stirred up by rival WLAN chipmaker Broadcom through the modern Las Vegas Comdex clearly show.
Considering that Broadcom used a 2Mbps MPEG stream as aspect of their Comdex demonstration, I also desired to include streaming as A part of my testing. But I desired a measure more quantitative than making an attempt to explain the diploma of jerkiness in the streaming online video of The Matrix.

Now if all of the Strength on the transmitted signal actually have been contained in a 20 (or 22MHz) band, the definition of “non-overlapping” might be less difficult. But fact is rather additional difficult.
As the little bit price is restricted to 2Mbps, the spectrum generated isn’t quite vast, which should really limit the channel overlap, and superg168 therefore the level of overall performance degradation.
Neither is Super-G’s “rapidly frames” element – which inserts numerous facts packets into only one info frame – because it’s also part of the 802.
The timing seemed to be 45 seconds of Tremendous-G and 15 seconds of 11g during the NETGEAR BETA dynamic Super-G updates that I used. A special implementation of dynamic Tremendous-G in D-Link Super-G enabled gear employed by Broadcom in its testing confirmed the timing to be a hundred and twenty seconds of Tremendous-G and seventy five seconds of 11g. So it seems like Atheros, NETGEAR, or each are doing some effectiveness tuning.
And whilst it’s true that two 11g WLANs can interfere with one another as Atheros contends, it’s only when equally are operating entire-tilt, and in some cases then, the interference is long gone by the time the WLANs are separated by thirty toes – properly in need of the 100 ft that Atheros has long been quoted as stating will be the 11g interference zone.
The total implementation of Super-G has equally static and dynamic modes. One of the distinctions are that static manner units will only talk to other Tremendous-G equipment and channel bonding is usually kicked in.
But before you go off questioning why Atheros would build “an 802.11g jammer” – to estimate 1 Broadcom promoting exec, as opposed to a brand new typical in wi-fi LAN performance, go on on to Section two of the Want To Know.
