1) The list is still functioning.. as I received your message.. 

2) I don't have a dumb answer.. I used to be on this list to try to learn by listening to others, having very little to contribute from my end, LOL!

G'Day All. 

I think it has been a while since this list was used so it will be 
interesting to see is people are still around. I was going to post this to 
the SpreadSpectrum mailing list, but it has been shut down since it was not 
used for so long.   

Anyway, last night I was at a presentation for a security company here in 
Australia that was promoting a technology called Binary-CDMA for video 
cameras because 'the security industry is losing the wireless battle', 
presumably with 2.4 GHz Wifi, Bluetooth, ZigBeeT, etc etc etc. The company 
is claiming 55 MBPS and 3.5 km range. 

So here is the dumb question... What is BINARY CDMA? 

I have found two references without much detail 


Any ideas would be appreciated
