Re: CDMA - Looks like there is a strong trend to OFDM, based on the ability to assign a single channel to the mobile or remote units, and thus operate at much lower power, meaning longer battery life. OFDM is part of the new WiMax specs. OFDM also seems to work much better with MIMO multiple antenna schemes, which allow for frequency re-use by nulling out some signals adjusting the phase recieved from multiple antennas. You get 3 or more antennas, null out signal A, then use the reciever for signal B. Another reciever gets tunned to null out B, and recieve A. Nice thing is the nulling is done in DSP, so one set of hardware, and multiple virtual recievers.
