1. A method for performing rate adaptation of millimeter wave transmissions in a substantially line-of-sight OFDM outdoor system, wherein said millimeter wave transmissions are performed over a radio frequency (RF) channel, comprising: receiving a channel quality estimator indicative of a quality of an outdoor millimeter-wave RF channel; defining a sequence of parameter changes to dynamically adjust transmission quality for said rate adaptation, said parameters defining said rate adaptation, and comprising dynamic adaptation of bandwidth and at least one other parameter, storing said sequence as a table of vectors, one parameter of said vectors being bandwidth, each vector comprising a combination of parameters, and dynamically working through said parameter vectors in said table in response to said channel quality estimator.
