A nearby Tremendous-G WLAN jogging a 2Mbps movie stream will probably not lead to substantial interference to an 11g WLAN that’s also streaming a online video.
The ink experienced rarely dried within the 802.11g conventional when wi-fi chip manufacturers started to roll out non-normal throughput “enhancement” systems.
Atheros has explained that Broadcom is harping on a little something widespread to all 802.11g products and solutions and that interference will even be produced by “normal” 802.11g WLANs functioning in near proximity. So I 1st needed to exam to check out if this have been accurate.
Due to the fact one of the two WLANs had to move to check at different distances, and because I have only two notebooks, I employed them both within the Super-G 50 % of my take a look at rig to generate things straightforward to maneuver all around.
Super-G vs. Broadcom 11g screening consisted of using the preceding eventualities and repeating them While using the Atheros-based mostly NETGEAR pair now established to Tremendous-G mode.
A close-by Tremendous-G WLAN managing a 2Mbps movie stream will most likely not cause considerable interference to an 11g WLAN that’s also streaming a movie
This test is meant to emulate the Broadcom Comdex demo (apart from that it uses two 802.11g WLANs) and identify the extent of interference on a online video stream from a nearby WLAN that’s working as speedy as it can go.
The styles of your alerts search distinctive from Those people shown in Determine 3 mainly because filtering is utilized from the WLAN products to form the sign. However , you can clearly see that ability from Each individual channel’s signal overlaps into one another’s.
Chariot doesn’t include things like MPEG streams amongst its examination scripts. superg168 So I'd to create do using the NetMtgv.scr script, which emulates a NetMeeting two.1 Video clip stream. I made use of UDP because the protocol and established the stream rate to 2.048Mbps.
When Tremendous-G drops back to ordinary 11g close to the conclusion from the operate, you are able to see throughput return nearly 2Mbps and Details Decline fall to zero, as we saw in the 11g-only screening.
Fortuitously, Chariot contains the ability to simulate movie streams, and calculates the Dropped Knowledge within a stream. As a result of buffering and mistake recovery mechanisms crafted into streaming protocols, it’s tough to instantly correlate a Misplaced Knowledge quantity towards the quantity and severity of glitches within a streaming online video.
This estimate is barely superior for 3 days. All present-day revenue represented inside the quotation are only legitimate through sale date
Broadcom states the periodic glitch is due to a scan finished by WinXP’s “Zero Configuration” utility, rather than by Broadcom’s driver.
The outcome show 0.041% of data was lost within the Broadcom-based mostly stream and none within the Atheros-based stream. This isn’t actually really major, especially given that the most important disturbance is thanks the glitch brought on by the Broadcom driver.
