PoC of Analog mmWave Repeaters for 5G/6G Cellular Networks
The millimeter-wave (mmWave) band is a key technology for high-speed, large-capacity communications in 5G and beyond due to its wide bandwidth. However, severe propagation loss at high frequencies limits coverage, especially in non-line-of-sight environments.
To address this issue, analog mmWave repeaters with beamforming capability have attracted attention as a cost-effective solution for coverage extension. In this research, we experimentally evaluate the performance of mmWave repeaters in a real 5G environment constructed at the Ookayama campus of the Institute of Science Tokyo.
Bullet Points Item
- Field deployment and PoC evaluation of analog mmWave repeaters
- Coverage extension using multi-hop wireless transmission
- Achieved over 1 Gbps downlink throughput with repeaters
