A close-by Super-G WLAN functioning a 2Mbps movie stream will probably not cause significant interference to an 11g WLAN that’s also streaming a video.
The ink experienced hardly dried about the 802.11g regular when wi-fi chip companies began to roll out non-normal throughput “improvement” systems.
Dynamic mode is intended for use in mixed WLANs and will take into consideration the categories of stations (clients) in the WLAN as well as their bandwidth calls for.
Super-G doesn’t Examine to view if 11b or 11g expectations-compliant devices are in vary in advance of employing its non-conventional procedures
Because Broadcom made use of a 2Mbps MPEG stream as portion in their Comdex demonstration, I also preferred to incorporate streaming as part of my screening. But I needed a evaluate a lot more quantitative than striving to describe the degree of jerkiness inside of a streaming video clip on the Matrix.
Atheros declared its Tremendous-G throughput improvement technologies again in April of this yr, nevertheless it’s taken right until now for products and solutions to hit the cabinets.
This examination is meant to emulate the Broadcom Comdex demo (apart from that it takes advantage of two 802.11g WLANs) and establish the extent of interference over a video clip stream from a nearby WLAN that’s managing as speedy as it might go.
The shapes on the signals seem various from Those people shown in Determine three for the reason that filtering is applied within the WLAN units to condition the sign. However you can clearly see that electricity from Each individual channel’s sign overlaps into each other’s.
Because the little bit charge is restricted to 2Mbps, the spectrum produced isn’t extremely vast, which must limit the channel overlap, and therefore the amount of performance degradation.
The downside – as Broadcom needs All people to learn – is always that Channel Bonding cuts a broader swath during the two.4GHz spectrum, allegedly interfering with all eleven channels during the 2.

Atheros’ Channel Bonding know-how isn’t new, as it’s been employed for a number of years now in Atheros’ 802.11a “Turbo” function. NETGEAR’s 108Mbps Know-how overview paper describes that Channel Bonding operates by making use of two radio channels in a method that they appear as a single, greater-pace channel to both of those the transmitter and receiver.
As I explained in my Comdex protection, the quick story is always that Broadcom is asserting that Atheros’ Super-G centered products and solutions will interfere with neighboring 802.11b and g networks, seriously restricting their speed and, in some cases, shutting them down fully.
The superg168 final results demonstrate 0.041% of data was misplaced inside the Broadcom-based stream and none inside the Atheros-based mostly stream. This isn’t actually really considerable, especially because the largest disturbance is due the glitch caused by the Broadcom driver.
