... In each channel, digital modulation techniques with high spectral efficiency may be used, such as 256-QAM (7 (bit/s)/Hz). The fibre may penetrate deeper into the network, thereby reducing the number of subscribers served by each RN to about 50 (instead of 500, typical of the HFC architecture). Multi ...
