A thread in the Slashdot article The 700MHz Question drifted into a discussion between me and rcw-home/rcw-work on using multiple antennas to synthesyze multiple patterns. This allows a particular hunk of bandwidth to be reused to generate several full-bandwidth links simultaneously - either between a base station and several remote stations or even between the base station and a single remote station that itself has multiple antennas.
The thread is beginning to horzon out on my user info history. So this journal entry is a new venue for its continuation after rcw-*'s most recent post.
I'll respond to that after he posts here to indicate that he's also making the move.
