A nearby Super-G WLAN managing a 2Mbps video stream will probably not induce substantial interference to an 11g WLAN that’s also streaming a online video.
It appears that even if a dynamic Tremendous-G AP doesn’t detect “typical” 11g or 11b consumers in variety, it will tumble again to normal 11g on the periodic foundation.
Atheros has mentioned that Broadcom is harping on a thing common to all 802.11g merchandise and that interference can even be produced by “ordinary” 802.11g WLANs working in near proximity. So I 1st wished to examination to see if this were being accurate.
NOTE: The next spectrum diagrams are based upon Figure 1 and they are not performed to precise scale. Any inaccuracies are certainly not intentional!
Nitro and Xpress are generally focused on enhancing the whole throughput of numerous units that utilize them in combined 802.11b / g networks. (You may even see slight throughput improvement for an individual AP / client pair, depending on drivers, OSes along with other components.)

The upside is that Tremendous-G definitely does supply drastically elevated throughput and – unlike Nitro and Xpress – doesn’t rely on blended mode aggregate throughput gains to deliver its gain.
Broadcom alleges that Super-G’s channel bonding element can noticeably degrade the general performance of neighboring 2.4GHz WLANs that don’t use Super-G. Broadcom’s Comdex demos centered on displaying two Tremendous-G behaviors that Broadcom suggests are the root of the trouble:
Dynamic manner in an AP lets 802.11b, 11g, and Super-G STAs all associate and transfer knowledge and switches in channel bonding only superg168 when bandwidth requires require it.
Fortuitously, Chariot consists of the ability to simulate movie streams, and calculates the Shed Knowledge inside a stream. Due to buffering and mistake recovery mechanisms created into streaming protocols, it’s hard to directly correlate a Dropped Data selection on the range and severity of glitches within a streaming video.
Atheros’ Channel Bonding know-how isn’t new, as it’s been useful for a several years now in Atheros’ 802.11a “Turbo” characteristic. NETGEAR’s 108Mbps Engineering overview paper describes that Channel Bonding is effective by using two radio channels in a means that they appear as a single, increased-speed channel to each the transmitter and receiver.
A brilliant-G WLAN jogging at whole speed will severely interfere having an 11g WLAN working streaming video even at 30 toes. Although the interference is actually gone at fifty toes.
The outcome is analogous to “multilink” tactics used by ISDN and a few dialup ISPs, although the exact mechanics are distinctive.
