RE: Information of PER for shared antenna?
Tom,
Not associate with 15.2, that is terrible. It was a great group
of people. :) We will forgive you.
You can get the recommended practice on Get802 I believe.
You are correct, that AWMA is a time division multiple access
technique switching between 802.11 and BT. During the WLAN time segment
there is no Bluetooth traffic, assuming all the devices are using AWMA.
And during the BT time interval there is no WLAN traffic.
If we have no official interest from the BT SIG then I guess
there is no problem.
If anyone from CSR want to have a discussion or make a
presentation at 802.19 that would be fine. If so please give me a bit
of advanced notice so I can give Sheung Li a heads-up so he can attend.
Regards,
Steve

Thanks Steve,
For reasons not clear now (but clear then) I was specifically not
allowed to be associated with 15.2 by my employer, and I never went back
and studied it later. I'll check it out.
I suspect the AWMA is a bank-switch signaling mechanism, which I think
is already being used. I'll verify, but what I believe is being asked
is being asked is any data/analysis on induced errors because of
proximity of another transmitter.
As far as Bluetooth and 11n are concerned, it may well be that the
Bluetooth SIG as an organization is not interested in the interaction
with 11n, but some of the members definitely are. I will see what
interest I can generate from Cambridge about participation in the
analysis.
