Technical FAQs 4

How many 5G base stations did SoftBank and KDDI build?

Through 5G JAPAN, SoftBank and KDDI have jointly built out over 5G 38,000 base stations each, resulting in capital expenditure cost reductions of 45.0 billion yen for each company *2.

How can a 5G network improve quality in Japan?

This involves expanding network coverage and density, as well as developing commercial models that facilitate value-based widespread use. Massive MIMO is another key technology for maintaining and enhancing the quality of the 5G network in Japan.

Can Japan take 5G to the next level?

However, with fewer 5G site deployments compared to 4G and a mid-tier ranking for mobile on the latest Speedtest Global Index from Ookla, Japan’s global competitiveness is at risk. Today, the country has a unique opportunity—and a growing need—to take the 5G network in Japan to the next level.

Should CSPs launch 5G SA networks in Japan?

While many CSPs have technically launched 5G SA networks, including in Japan, the challenge lies in driving adoption at scale. This involves expanding network coverage and density, as well as developing commercial models that facilitate value-based widespread use.
