TL;DR: The operation of real-time Giga-bit mobile services such as 4K video streaming over IFoF-based mobile fronthaul for 5G prototypes with a 28-GHz mmWave successfully demonstrates the flexibility and efficiency of wavelength operation.

TL;DR: The successful demonstration of an intermediate-frequency-over-fiber (IFoF)–based radio access network (RAN) for 28 GHz millimeter-wave (mmWave)- based 5G mobile communication confirmed that the IFoF technology was capable of supporting RANs for mmWave-based 5G networks and providing real-time multi-Gb mobile services.

TL;DR: 4 × 4 multiple-input and multiple-output (MIMO) supporting mmWave-based indoor 5G mobile network based on a distributed antenna system (DAS) that has over-the-air interface to receive the broadband wireless signal from, e.g., remote radio head (RRH) of mobile fronthaul.

TL;DR: The 5G connected car service, which is one of the 5G key services, is successfully demonstrated through deployed IFoF-based DAS through a seamless handover at the intersection of baseband unit and DAS deployed sections to smoothly support 5G-based autonomous driving service.

TL;DR: The IFoF-based 4 × 4 MIMO supporting analog indoor DAS is capable of providing record high peak throughput of 5.3 Gb/s for millimeter wave based 5G mobile communication system.
