Summary of Mobile Spectrum Availability in Different Markets

Core Content

This report compares the total mobile spectrum availability in different global markets, focusing on low, mid, and high bands. It outlines current and potential future spectrum assignments, including both licensed and unlicensed frequencies, and highlights the US's position relative to other countries.

Key Findings

Low Band

• US Leadership: The US has the largest amount of licensed low-band spectrum available, totaling 752 MHz.
• Future Assignments: Other countries are planning to add an average of 90 MHz of licensed low-band spectrum. This will be critical for maintaining US leadership in this band.
• Unlicensed Spectrum: Unlicensed spectrum in the 2.4GHz, 5GHz, 6GHz, and 57–66GHz bands is available in all markets, averaging 84 MHz.

Mid Band

• Unlicensed Advantage: The US has 1860 MHz of unlicensed mid-band spectrum, which is 3.2 times more than the next closest countries (Hong Kong, Qatar, and the UK, each with 580 MHz).
• Licensed Mid-Band: The US currently has no licensed spectrum in the 3.3–3.6GHz band, which is a key global 5G range. Other countries have an average of 200 MHz in this band.
• Future Potential: The US is exploring the possibility of adding 250 MHz or more in the lower 3GHz band, which could position it as a leading benchmark country. The FCC and NTIA are considering this.
• Unlicensed vs. Licensed: In mid and high bands, the US has made around three times as much unlicensed spectrum available as licensed spectrum. Over the next few years, the share of licensed spectrum is expected to increase to 55%.

High Band

• US Leads in Licensed High-Band: The US currently leads in licensed high-band spectrum, with 8300 MHz potentially available.
• China's Potential: China may catch up, with 8250 MHz of licensed high-band spectrum expected to be available in the next few years.

Main Points

• The US has a strong position in low-band spectrum due to its extensive licensed assignments.
• The US has a significant advantage in unlicensed mid-band spectrum, especially in the 6GHz band.
• In the mid-band, the US lacks licensed spectrum in the 3.3–3.6GHz range, which is a key 5G band.
• The US is exploring additional licensed mid-band spectrum, which could enhance its position.
• In high bands, the US is expected to maintain its lead, although China is close behind.

Key Information

• Spectrum Categories:

  • Low bands: below 2.6 GHz
  • Mid bands: 3–7 GHz
  • High bands: millimeter-wave (mmWave) region

• Sources:

  • Data is based on the most recent information from national regulatory authorities (NRAs) and relevant government agencies.
  • Additional data from WRC, ITU, regional organizations (APT, CEPT), and standards bodies (ETSI, 3GPP) has been used to supplement the analysis.

• Approach:

  • Only spectrum that has been specifically consulted on or is likely to be assigned within the next five years has been included.
  • Temporary spectrum assignments and unlicensed spectrum not suitable for mobile use have been excluded.

Tables Overview

Low Band

• Current Assignments: The US has 752 MHz of licensed spectrum, while other countries have varying amounts.
• Potential Future Assignments: The US is expected to maintain its lead, with future additions likely to be in the low-band range.

Mid Band

• Current Assignments: The US has 600 MHz of licensed spectrum and 1860 MHz of unlicensed spectrum.
• Potential Future Assignments: The US is likely to gain more licensed spectrum in the lower 3GHz band, while other countries are considering additional unlicensed spectrum.

High Band

• Current Assignments: The US has 5550 MHz of licensed spectrum and 14,000 MHz of unlicensed spectrum.
• Potential Future Assignments: China is expected to increase its licensed high-band spectrum availability to 8250 MHz, close to the US's 8300 MHz.

Conclusion

The US holds a significant advantage in low and mid-band spectrum, particularly in unlicensed mid-band. However, in the mid-band 3.3–3.6GHz range, the US lags behind other countries. The US is expected to maintain its leadership in high-band spectrum, although China may approach it in the coming years. Future spectrum availability will depend on regulatory decisions and national policies.
