SO(5) $\times$ U(1) $\times$ SU(3) gauge-Higgs unification model inspired by SO(11) gauge-Higgs grand unification is constructed in the Randall-Sundrumwarped space.
The 4D Higgs boson is identified with the Aharonov-Bohm phase in the fifth dimension.
Fermion multiplets are introduced in the bulk in the spinor, vector and singlet representations of SO(5) such that they are implemented in the spinor and vector representations of SO(11).
We discuss collider physics at International Linear Collider.
