My very last set of 11g-only exams mixes The 2 situations by working the streaming script about the Broadcom-based WLAN as well as throughput script within the Atheros-centered.

The ink experienced rarely dried to the 802.11g regular when wireless chip manufacturers started to roll out non-normal throughput “improvement” systems.

Determine ten supplies somewhat more insight because it displays the data lost by Each and every stream, that is the distinction between the Bytes despatched and Bytes gained.

Since one of several two WLANs had to move to check at various distances, and because I have only two notebooks, I used them both in the Tremendous-G half of my take a look at rig to help make items straightforward to move about.

Tremendous-G vs. Broadcom 11g screening consisted of getting the prior eventualities and repeating them with the Atheros-based NETGEAR pair now established to Tremendous-G method.

A close-by Tremendous-G WLAN working a 2Mbps movie stream will probably not induce major interference to an 11g WLAN that’s also streaming a video

I tried both of those and found tiny variance when functioning the streaming and throughput scripts, so opted to make use of the more recent dynamic Super-G for my testing.

The styles in the indicators search diverse from those revealed in Figure 3 since filtering is utilized from the WLAN units to shape the signal. However, you can Obviously see that electricity from Every channel’s sign overlaps into one another’s.

Broadcom alleges that Super-G’s channel bonding characteristic can drastically degrade the efficiency of neighboring two.4GHz WLANs that don’t use Tremendous-G. Broadcom’s Comdex demos centered on showing two Tremendous-G behaviors that Broadcom claims are the root superg168 of the situation:

Neither is Super-G’s “rapidly frames” function – which inserts many facts packets into just one knowledge frame – since it’s also A part of the 802.

Atheros’ Channel Bonding technological innovation isn’t new, as it’s been employed for a several years now in Atheros’ 802.11a “Turbo” feature. NETGEAR’s 108Mbps Know-how overview paper points out that Channel Bonding works by using two radio channels in a method that they seem as an individual, bigger-pace channel to each the transmitter and receiver.

As I explained in my Comdex coverage, the shorter Tale is the fact Broadcom is asserting that Atheros’ Tremendous-G based mostly products and solutions will interfere with neighboring 802.11b and g networks, severely restricting their velocity and, occasionally, shutting them down totally.

Broadcom was notably absent from this primary round of announcements, opting rather (inside a surprisingly conservative move) to attend until eventually the ratification of 802.11g on June 13 to introduce its Xpress know-how.
