Has anyone tried a data capture of communications between 2 stations using turbo mode or as linksys calls it Speedbooster technology. Since this type of wireless communication widens the data signal over the spectrum and protocol analyzers can only capture packets on a single channel at a time is the band wide enough to make packet capture impossible or cause errors in the protocol decodes?
Turbo Mode
The multi-channel 108Mbps Turbo Mode capability operates by using the spectrum offered by two radio channels to overcome the RF physics limitations of Shannon?¡é?€??s Limit, which dictates the number of bits that may be transmitted per MHz of spectrum. The data rate doubling is the most obvious effect of using multiple radio channels. By providing an optional capability that uses multiple radio channels simultaneously, Super G Turbo mode can double the data rates offered by any single radio channel techniques. The multi-channel mode give multi-channel devices high bandwidth on demand, but also to check for and fall back to single-channel operation if necessary because of the presence of legacy devices.
When Turbo mode is set to enabled, Channel 6 is used and cannot be changed to any other channels.
The above is from D-links web site. It states that turbo mode uses 2 channels but then says that Turbo mode uses channel 6. So I am wondering if turbo mode might bleed into channel 5 and 7 thus making it possible to reliably capture packets and not show corruption in the decode?
