Through trailing Open RAN kit, Japan via the Quad hopes to encourage other nations to adopt the technology. The Quad leaders also issued an Open RAN Security Report, commissioned and financed by the Japanese Ministry of Internal Affairs and Communications, and written in cooperation with Japanese industry partners, including a mobile network operator. The report was unsurprisingly positive. Pushing back on criticism that Open RAN is less secure than a fully integrated traditional RAN network, the report stated that the risks are not significantly different.
Japanese companies are active in seeking to capitalise on government support. At the 2024 Mobile World Congress in Barcelona, Japan’s largest network operator NTT Docomo and tech company NEC announced a joint venture to grow their Open RAN business with a focus on Southeast Asia and the Middle East. The venture will launch three international trails of Open RAN in Singapore, the Philippines and Qatar. The first trial, taking place in the Philippines is being partly funded by the Japanese government, with construction to begin within months. In Japan, meantime, Rakuten is among the first companies to deploy an Open RAN network anywhere in the world.
The promotion of Open RAN at the Quad is not new. In 2022, the group announced that it would “advance interoperability and security through the signature of a new Memorandum of Cooperation on 5G Supplier Diversification and Open RAN.” Similarly, the first ever Quad Leaders’ Summit held in 2021 agreed to “support 5G deployment and diversification”, primarily through Open RAN.
Outside the Quad, Prime Minster Fumio Kishida has promoted 5G/Open RAN technology in several prominent international speeches.
Through it all, Japan has been the Quad’s driving force on this issue. While the US has a handful of companies such as Mavenir which it has sought to promote through similar actions to Tokyo’s, Japan has been the leader.
Whether Japan achieves success in promoting its champions through the Quad remains to be seen, but Tokyo is showing no signs of giving up.
