A nearby Tremendous-G WLAN managing a 2Mbps video clip stream will most likely not induce important interference to an 11g WLAN that’s also streaming a movie.
You probably would never ever detect interference between two 11g WLANs functioning online video streams at any distance.
Dynamic manner is meant for use in mixed WLANs and usually takes into account the kinds of stations (shoppers) from the WLAN and their bandwidth needs.
Because one of many two WLANs had to maneuver to check at various distances, and since I've only two notebooks, I applied them equally while in the Tremendous-G fifty percent of my test rig to generate factors effortless to move around.
Super-G vs. Broadcom 11g screening consisted of getting the prior scenarios and repeating them With all the Atheros-dependent NETGEAR pair now established to Tremendous-G method.
By the way, the drop in Super-G throughput across the 55 second mark is not due to conversation involving the Tremendous-G and 11g WLANs, but alternatively to Portion of dynamic Tremendous-G’s algorithms.
I attempted the two and found minimal big difference when operating the streaming and throughput scripts, so opted to utilize the More moderen dynamic Tremendous-G for my tests.
Due to the fact this test takes advantage of every one of the bandwidth that every WLAN has to present, the spectrum produced by Each individual WLAN might be most width, leading to a worst-situation channel overlap and worst-circumstance interference situation.
Chariot doesn’t include MPEG streams among the its check scripts. So I'd for making do utilizing the NetMtgv.scr script, which emulates a NetMeeting 2.one Movie stream. I used UDP since the protocol and established the stream price to two.048Mbps.
Dynamic method in an AP lets 802.11b, 11g, and Tremendous-G STAs all affiliate and transfer knowledge and switches in channel bonding only when bandwidth needs need it.
The timing appeared to be forty five seconds of Super-G and 15 seconds of 11g while in the NETGEAR BETA dynamic Super-G updates which i utilized. A different implementation of dynamic Tremendous-G in D-Hyperlink Super-G enabled gear utilized by Broadcom in its tests showed the timing to generally be a hundred and twenty seconds of Tremendous-G and 75 seconds of 11g. So it appears like Atheros, NETGEAR, or both equally are doing a little overall performance tuning.
Atheros’ Channel Bonding technology isn’t new, as it’s been used for a several years now in Atheros’ 802.11a “Turbo” element. NETGEAR’s 108Mbps Engineering overview paper describes that Channel Bonding is effective by making superg168 use of two radio channels in a method that they seem as only one, better-velocity channel to equally the transmitter and receiver.
Broadcom says the periodic glitch is because of a scan carried out by WinXP’s “Zero Configuration” utility, and not by Broadcom’s driver.
The result is similar to “multilink” strategies utilized by ISDN and several dialup ISPs, although the correct mechanics are various.
