We make a detailed study of the unification of gauge couplings in the MSSM with large extra dimensions. We find some scenarios where unification can be achieved [with {alpha}{sub 3}(M{sub Z}) within 1{sigma} of the experimental value] with both the compactification scale and the SUSY breaking scale in the few TeV range. No enlargement of the gauge group or particle content is needed. One particularly interesting scenario is when the SUSY breaking scale is larger than the compactification scale, but both are small enough to be probed at the CERN LHC. Unification in two scale compactification scenarios is also investigated and found to give results within the LHC reach. (c) 2000 The American Physical Society.
