My final set of 11g-only tests mixes The 2 situations by jogging the streaming script over the Broadcom-based mostly WLAN and also the throughput script over the Atheros-based mostly.
There isn’t plenty of place within the 2.4GHz wi-fi LAN spectrum for that increased spectrum employed by channel bonding
Atheros has reported that Broadcom is harping on a little something popular to all 802.11g goods Which interference may even be created by “typical” 802.11g WLANs running in shut proximity. So I very first wanted to take a look at to view if this were being accurate.
Another thing is hitting the ,er, lover, though, in the shape of an argument stirred up by rival WLAN chipmaker Broadcom through the recent Las Vegas Comdex display.
This meant utilizing a desktop equipment and 11g USB2.0 adapters during the 11g 50 % of my testbed, which remained stationary for all assessments.

Now if every one of the Electricity of the transmitted signal basically were contained inside a twenty (or 22MHz) band, the definition of “non-overlapping” may very well be simpler. But reality is fairly extra challenging.
Chariot doesn’t include things like MPEG streams amongst its test scripts. So I'd to make do using the NetMtgv.scr script, which emulates a NetMeeting two.one Video clip stream. I applied UDP because the protocol and set the stream charge to two.048Mbps.
The downside – as Broadcom needs Everybody to grasp – is always that Channel Bonding cuts a wider swath within the two.4GHz spectrum, allegedly interfering with all eleven channels in the 2.
You’d be unlikely to notice interference involving two 11g WLANs running video clip streams at any distance
And whilst it’s real that two 11g WLANs can interfere with each other as Atheros contends, it’s only when the two are functioning full-tilt, and in some cases then, the interference is absent by the time the WLANs are separated by 30 ft – very well wanting the 100 feet that Atheros has long been quoted as saying would be the 11g interference zone.
As I explained in my Comdex protection, the short Tale is the fact Broadcom is asserting that Atheros’ Super-G based products will interfere with neighboring 802.11b and g networks, severely restricting their speed and, in some instances, shutting them down wholly.
Broadcom was notably absent from this primary spherical of announcements, opting rather (inside of a surprisingly conservative shift) to wait until finally the ratification of superg168 802.11g on June 13 to introduce its Xpress technological know-how.
