Total bandwidth with MIMO and "smart antennas"

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.

  • I have long been interested in this. The treatment of spectrum as real-estate has always seemed faintly off to me, and learning about this kind of thing told me that it was way more than faintly off.

    You think of radio stations as giant flashing beacons (

    • And like you can have a sign with a bunch of lights on it, you can also have the receiver be able to distinguish between a bunch of closely spaced lights and send multiple signals using the same color from the transmitter to the receiver.

      This works great
