My previous set of 11g-only checks mixes The 2 situations by jogging the streaming script on the Broadcom-primarily based WLAN as well as throughput script over the Atheros-dependent.

You probably would by no means see interference amongst two 11g WLANs jogging movie streams at any distance.

Nitro and Xpress mostly use “packet (or body) bursting” to supply throughput improvement Super-G improves the throughput of even just one AP / client pair (i.e. calculated improvement doesn’t depend upon calculating the full throughput of several units in a very WLAN)

Since on the list of two WLANs experienced to maneuver to check at various distances, and since I've only two notebooks, I utilised them each within the Super-G 50 % of my test rig to make things quick to maneuver around.

Super-G vs. Broadcom 11g testing consisted of getting the past situations and repeating them Along with the Atheros-based NETGEAR pair now established to Super-G method.

In it, I’ll display that taking a look at just Broadcom-primarily based 11g vs. Atheros gear doesn’t notify the whole Tremendous-G story And that i’ll also investigate the connection among Tremendous-G and improved selection. And, naturally, I’ll have my own two cents to lead to this complete mess.

The styles with the signals glimpse unique from Those people demonstrated in Determine 3 because filtering is used while in the WLAN gadgets to condition the sign. However you can clearly see that energy from Each individual channel’s signal overlaps into each other’s.

Broadcom alleges that Super-G’s channel bonding aspect can significantly degrade the effectiveness of neighboring two.4GHz WLANs that don’t use Tremendous-G. Broadcom’s Comdex demos focused on displaying two Tremendous-G behaviors that Broadcom says are the foundation of the trouble:

I’ll then current the final results of exams which i’ve run in my house Place of work environment pitting not only Super-G versus “usual” 11g wi-fi LANs, but also “ordinary” 11g WLANs towards each other.

The timing gave the impression to be 45 seconds of Super-G and fifteen seconds of 11g while in the NETGEAR BETA dynamic Tremendous-G updates that I applied. A special implementation of dynamic Tremendous-G in D-Website link Tremendous-G enabled equipment used by Broadcom in its tests showed the timing to become one hundred twenty seconds of Super-G and seventy five seconds of 11g. So it looks like Atheros, NETGEAR, or both are performing some effectiveness tuning.

And when it’s correct that two 11g WLANs can interfere with each other as Atheros contends, it’s only when both equally are managing full-tilt, and in some cases then, the interference is gone by the point the WLANs are separated by thirty feet – properly in need of the one hundred feet that Atheros is quoted as saying would be the 11g interference zone.

The yellow shaded area represents the facility from channel two’s sign that overlaps into channel one’s major lobe (the biggest “hump” as superg168 well as the frequency band which contains a lot of the signal’s power).

Broadcom was notably absent from this primary spherical of bulletins, opting rather (inside a surprisingly conservative go) to wait right up until the ratification of 802.11g on June thirteen to introduce its Xpress engineering.
