After reading several posts for feature requests and the poll on the wiki, it got me to thinking about something that may (or may not) be possible.
Someone suggested making a single radio transmit on one channel, and receive on another. This solution would obviously require ROS on both ends, as well as being technically unfeasable for reasons someone else explained.
But what about using two radios on the ROS AP, with the intention of working with standard 802.11 CPE to accomplish a similar task:
In this hypothetical configuration, a high powered transmitter could be used, then located close enough to be useful (but spacially diverse enough to not be a problem) would be another antenna, coupled to another card which would only need good receive sensitivity.
The idea is, ONLY transmit with the high powered card. It's always in TX mode.
The second interface only receives for the SSID on the transmitter.
In this way, the AP is full duplex, but the client doesn't know any better and doesn't have any idea that there is anything other than a standard 802.11 AP at the other end.
It seems to me like this kind of configuration would significantly increase the subscriber density that could be achieved; without requiring the CPE to run ROS.
Don't get me wrong, I love the idea of ROS CPE. The problem is I've got 400 CPE's out there at aren't ROS, and I can't replace them. If I was starting from scratch today, it'd ALL be ROS; but for us that simply is not an option.
This would allow me to make some changes at the AP to increase density, without having to replace each subscriber CPE, as well as add another feature feather to the ROS cap!
