Field Experiment on 5-Gbit / s Ultra-high-speed Packet Transmission Using MIMO Multiplexing in Broadband Packet Radio Access

Hidekazu Taoka and Kenichi Higuchi An ultra-high-speed packet transmission experiment for achieving a transmission data rate of approximately 5 Gbit/s (spectral efficiency of 50 bit/s/Hz) was performed using a 100-MHz channel bandwidth in broadband packet radio access. The spectrum efficiency of 50 bit/s/Hz nearly approaches the upper limit in cellular environments near a cell site taking into account inter-cell interference. We describe the technology overview, experimental configuration, and field experimental results to achieve the data rate of 5 Gbit/s.
