Yes, but that would be of no use if the solution does not support it. In our case the current solution(WiFi module) is driven by the CPU and does not have this capability and can not be initialized based on a saved state.
I guess a better way to ask this question would be: is there an off-the-shelf small-foot-print 802.11 b or g solution which would support this?
In regards to preventing the device from going into suspend mode, that is actually the workaround we have suggested for the time being and since our solution has a fairly good PS mode with sleep intervals of 100ms to 1s we are able to make up for the battery usage to an extent, but that does kill the battery life as you pointed out, and hence we are trying to find a better solution as this just seems to be a H@ck!
