Conclusion We have performed experimental demonstration of transmitting 28-GHz band radio signals to radio dead area inside a vehicle by re-radiation of cost-effective A-RoMMF employing a directly modulated VCSEL. SNR of the radio signals inside the vehicle were dramatically improved by this A-RoMMF, and thus, the 64-QAM signals with 400-MHz bandwidth in the 28-GHz band were successfully demodulated.
