* 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.

What is loss of orthogonality means in OFDM technology?
In OFDM, sub-carrier spacing is maintained in such a way that the maximum of one sub-carrier occurs at the minimum of the successive sub-carrier, a loss of orthogonality results if this pattern is not achieved in the sub-carriers of OFDM transmission. Loss of orthogonality is due to ISI, ICS, Frequency offset amongst the sub-carriers of OFDM.
How you eliminate inter symbol interference in ofdm?
Inter symbol interference (ISI) in OFDM systems can be minimized by using a cyclic prefix. This involves adding a copy of the end of each OFDM symbol to the beginning before transmission. The cyclic prefix helps to mitigate the effects of multipath fading and reduces ISI by allowing the receiver to separate the OFDM symbols with a guard interval.
