  In extensions of the Standard Model with compactified extra dimensions,
perturbative unitarity of the longitudinal gauge bosons is maintained through
the contribution of heavy KK excitations of the gauge fields, without the
necessity of introducing a Higgs field. The Three-Site Higgsless Model
represents a minimal approach in this respect, containing just one extra set of
heavy gauge bosons Z'/W' in the spectrum. While the Z' can have robust
couplings to SM fermions and hence may be detected within the first 1-20 1/fb
of LHC data at 14 TeV, the coupling of the W' to light fermions is suppressed
and depends on the model parameters. Expanding on previous parton level
studies, we determine discovery thresholds of the W' in s-channel Drell-Yan
production at the LHC for W' masses of 380, 500 and 600 GeV, combining analyses
of the semileptonic final states lljj, lnjj and the leptonic final state lnll
including fast detector simulation.
