In fixed, i.e., point to point or point to multipoint applications, CDMA's bits per hertz efficiency is too low. Bingo!! The one attribute of CDMA which is attractive in a fixed system is privacy and security. The inherent inability to eavesdrop on the transmission mitigates much of the security concerns regarding the use of wireless for commercial applications IT isn't solely CDMA that makes this so, but also Spread Spectrum as well. If VODFM can deliver the bit payload they are claiming, which remains to be demonstrated, it would be the superior system. Note however, that other modulation techniques achieve similar capacities. The real sizzle (not yet steak) of VOFDM is the claim that it eliminates - or at least greatly mitigates - line-of-sight issues. Orthogonality is pervasive in emerging technologies. ADSL use it in wire side. Multi Coded standards such as MC-CDMA is also using orthogonal modulation to achieve a better bit per Hertz.
