The gauge couplings WWZ, WWWW, and WWZZ in the gauge-Higgs unification scenario in the Randall-Sundrum warped spacetime remain almost universal as in the standard model, but substantial deviation results for the Higgs couplings. In the SO(5) X U(I)B-L model, the couplings WWH and ZZH are suppressed by a factor COS OH from the values in the standard model, while the bare couplings WWHH and ZZHH are suppressed by a factor 1-2/3 sin(2) H-theta. Here H-theta is the Yang-Mills AB phase (Wilson line phase) along the fifth 5 dimension, which characterizes the electroweak symmetry breaking. The suppression can be used to test the gauge-Higgs unification scenario at LHC and ILC. It is also shown that the WWZ coupling in flat spacetime deviates from the standard model value at moderate values of OH, contradicting with the LEP2 data.
