My final list of 11g-only assessments mixes the two eventualities by jogging the streaming script over the Broadcom-primarily based WLAN and the throughput script on the Atheros-centered.
It’s unlikely you’d be appreciably bothered by a neighbor’s greatly utilized 802.11g WLAN though looking at a wirelessly streamed online video by yourself.
This time the two the throughput and Misplaced Info plots are worthy of demonstrating, as you can clearly see distinctions in both.
Something else is hitting the ,er, admirer, however, in the shape of an issue stirred up by rival WLAN chipmaker Broadcom in the course of the the latest Las Vegas Comdex show.
Tremendous-G vs. Broadcom 11g testing consisted of using the previous eventualities and repeating them With all the Atheros-primarily based NETGEAR pair now established to Tremendous-G method.

The styles with the alerts glance various from All those demonstrated in Determine 3 mainly because filtering is utilized within the WLAN devices to condition the sign. But you can Plainly see that power from Every single channel’s sign overlaps into one another’s.
Because the bit fee is limited to 2Mbps, the spectrum produced isn’t quite huge, which must limit the channel overlap, and for that reason the level of functionality degradation.
When Tremendous-G drops back to ordinary 11g near the finish from the run, you'll be able to see throughput come back around 2Mbps and Details Reduction fall to zero, as we saw inside the 11g-only testing.
With this NTK, I’ll very first explain what Super-G is and afterwards take a look at The crucial element supply of Broadcom’s concern.
And while it’s true that two 11g WLANs can interfere with one another as Atheros contends, it’s only when both are superg168 functioning total-tilt, and in many cases then, the interference is absent by the time the WLANs are separated by thirty ft – nicely in need of the a hundred feet that Atheros continues to be quoted as stating would be the 11g interference zone.
The yellow shaded location represents the power from channel two’s signal that overlaps into channel one’s principal lobe (the largest “hump” and in addition the frequency band which contains many of the sign’s electric power).
But it really’s safe to claim that lower Misplaced Facts numbers are better than increased, and employing Missing Information being a measurement can be a hell of lots simpler than attempting to describe how a video clip is breaking up!
