The SO(5) x U(1) gauge-Higgs unification in the Randall-Sundrum warped spacewith the Higgs boson mass m_H=126 GeV is constructed. An universal relation isfound between the Kaluza-Klein (KK) mass scale $m_{KK}$ and the Aharonov-Bohm(AB) phase $\theta_H$ in the fifth dimension; $m_{KK} \sim 1350 GeV/(sin\theta_H)^{0.787}$. The cubic and quartic self-couplings of the Higgs bosonbecome smaller than those in the standard model (SM), having universaldependence on $\theta_H$. The decay rates H -> \gamma \gamma, gg are evaluatedby summing contributions from KK towers. Corrections coming from KK excitedstates are finite and about 0.2% (2%) for $\theta_H= 0.12 (0.36)$, branchingfractions of various decay modes of the Higgs boson remaining nearly the sameas in the SM. The signal strengths of the Higgs decay modes relative to the SMare $\sim cos^2 \theta_H$. The mass of the first KK $Z$ is predicted to be $5.9(2.4)$TeV for $\theta_H= 0.12 (0.36)$. We also point out the possibleenhancement of $\Gamma(H -> \gamma\gamma)$ due to the large $U(1)_X$ charge ofnew fermion multiplets.
