The quantity of overlap concerning the normal 11g and Super-G signals would've more Plainly illustrated if all had been plotted at exactly the same length so that every one peak signal ranges were equal, but this is what Atheros provided.
It’s unlikely you’d be significantly bothered by a neighbor’s closely employed 802.11g WLAN whilst observing a wirelessly streamed video yourself.
Atheros has claimed that Broadcom is harping on one thing common to all 802.11g items Which interference may also be produced by “normal” 802.11g WLANs functioning in shut proximity. So I to start with wanted to test to find out if this were legitimate.
Observe: The subsequent spectrum diagrams are according to Figure one and so are not completed to exact scale. Any inaccuracies are certainly not intentional!
Nitro and Xpress are generally focused on improving the total throughput of multiple products that utilize them in mixed 802.11b / g networks. (You may see slight throughput advancement for a single AP / shopper pair, dependant upon motorists, OSes together with other factors.)

This exam is intended to emulate the Broadcom Comdex demo (apart from that it takes advantage of two 802.11g WLANs) and identify the level of interference on the video clip stream from a nearby WLAN that’s working as speedy as it might go.
Idea: As I was putting superg168 alongside one another the testbed, I discovered Win98SE being limiting the Super-G throughput final results. When I switched the same Pc from jogging 98SE to WinXP Residence, Tremendous-G average throughput (with all pace enhancements running) jumped from 29Mbps to close to 37Mbps.
Chariot doesn’t include things like MPEG streams amongst its examination scripts. So I had to help make do using the NetMtgv.scr script, which emulates a NetMeeting 2.one Online video stream. I made use of UDP as being the protocol and set the stream amount to two.048Mbps.
The draw back – as Broadcom wishes Every person to be aware of – is that Channel Bonding cuts a broader swath within the two.4GHz spectrum, allegedly interfering with all eleven channels from the two.
Luckily, Chariot involves the chance to simulate video streams, and calculates the Shed Knowledge in a very stream. Due to the buffering and error recovery mechanisms crafted into streaming protocols, it’s difficult to right correlate a Lost Data number on the amount and severity of glitches in the streaming movie.
Atheros’ Channel Bonding technology isn’t new, since it’s been useful for a couple of years now in Atheros’ 802.11a “Turbo” feature. NETGEAR’s 108Mbps Technological innovation overview paper clarifies that Channel Bonding performs through the use of two radio channels in a method that they seem as one, higher-speed channel to each the transmitter and receiver.
A brilliant-G WLAN working at entire speed will seriously interfere with the 11g WLAN functioning streaming movie even at 30 feet. Even so the interference is essentially absent at fifty feet.
Broadcom was notably absent from this first round of bulletins, opting rather (within a shockingly conservative transfer) to wait right until the ratification of 802.11g on June 13 to introduce its Xpress engineering.
