(2) In areas where cost-effective investment is difficult, broadband infrastructure will be built taking both investment efficiency and the needs of communities into account. (3) Of these varieties of broadband service, super-high-speed broadband access, mostly based on FTTH, will cover 90% of households nationwide.
