This paper presents performance evaluation of mobile hotspot network (MHN) prototype system. The MHN was proposed to provide passenger's Internet access in railways. The system architecture and features of physical layer specification are provided. The evaluation is realized using hardware prototypes in roads for low speeds and using computer simulations for high speeds. The simulation results show the MHN-E system of 1GHz bandwidth can provides about 3.6 Gbps at 500 km/h. Furthermore, we conducts experiments to specify the effect of cross interference of polarized antennas. The results show the presence of that factor will affect the quality of the signals and degrade the data throughput.
