China’s Ministry of Industry and Information Technology (MIIT) has officially reserved 3.3-3.6 GHz and 4.8-5 GHz for the country’s 5G service, the 21st Century Business Herald reported, citing an official announcement.

The ministry said that it will also make more spectrum available at low frequencies (below 3 GHz) for 5G, and it will likely free up 3.6-4.2 GHz for future 5G allocation, the report said.

“Regarding the mid-band segment, many countries and enterprises are planning to wait for China,” an industry source said. “With the largest market, China will have the largest impact on the industrial chain. After China has established the mid-band segment, it will also speed up the maturity of the industrial chain.”

High frequency band, or the high-frequency millimeter wave, experienced disputes around the world. The United States, Canada, Japan and South Korea mainly support a 28GHz wave distribution program, while China and the EU mainly support the 24GHz scheme in millimeter wave.

China predicted that in 2025 the domestic 5G market would account for 1.1 trillion yuan (US$165.85 billion), or 3.2% of the mainland’s gross domestic product for that year, the report added.
