developed a remote radio head (RRH) used in a cellular base station for LTE
With this RRH, Sumitomo Electric has
realized a wireless output power of 80 W at 2.1 GHz at a low power consumption
of less than 270 W, achieving the industry’s highest class efficiency.
The next generation wireless
Locating the RRH closer to the
Conventionally, the base station
developed the RRH for a WiMAX base station in 2010. The Company has also
developed this year a new RRH for an LTE base station by incorporating a higher
efficiency power amplifier and the original pre-distorter. This newly developed
RRH demonstrates a wireless output of 80 W at a lower power consumption of less
than 270 W, achieving an improved efficiency of more than 30 percent.
