Advantages of ofdm

* Flexibility of deployment across various frequency bands with little needed modification to the air interface. * Averaging interferences from neighboring cells, by using different basic carrier permutations between users in different cells. * Interferences within the cell are averaged by using allocation with cyclic permutations. * Enables orthogonality in the uplink by synchronizing users in time and frequency. * Enables Single Frequency Network coverage, where coverage problem exists and gives Excellent coverage. * Enables adaptive carrier allocation in multiplication of 23 carriers = nX23 carriers up to 1587 carriers (all data carriers). * Offers Frequency diversity by spreading the carriers all over the used spectrum. * Offers Time diversity by optional interleaving of carrier groups in time. * Using the cell capacity to the utmost by adaptively using the highest modulation a user can use, this is allowed by the gain added when less carriers are allocated (up to 18dB gain for 23 carrier allocation instead of 1587 carriers), therefore gaining in overall cell capacity.
