The hyperfine interval of Cs 11s(2)S(1/2) is determined using ladder-type electromagnetically induced transparency (EIT) in a room-temperature cesium cell. EIT doublets are observed, and peak positions are identified by introducing the wavelength mismatching factor under the dressed state scheme. Theoretical simulation is performed by obtaining the solutions of optical Bloch equations and integrating them over Doppler velocities. Optical-pumping and two-photon coherence effects are also considered. Simulation results correlate well with experimental data. Finally, the magnetic dipole constant of Cs 11s(2)S(1/2) A = 38.81 +/- 0.23MHz is elucidated by adding a calibration field to increase the accuracy of the frequency scale.
