5G spectrum

Spectrum regulators worldwide are addressing the importance of mid-band spectrum. Ericsson engages in U.S. mid-band proceeding.

Many of the world’s leading regulators are moving rapidly to open mid-band spectrum for flexible use, not only to meet rising demand in their jurisdictions, but also to attract investment and innovation.

• Europe has already identified 3.4-3.8 GHz as their primary band for 5G and policymakers are moving to make hundreds of megahertz of mid-band spectrum available for licensed and unlicensed.
• China issued a consultation to make an additional 500 MHz of mid-band spectrum available.
• Japan is studying making an additional 1.1 GHz of mid-band spectrum available.
• Korea plans to auction the 3.4-3.7 GHz band in 2018/2019.
• Singapore issued a consultation on additional spectrum for mobile services.
• India recently issued a consultation regarding licensing 3.3-3.6 GHz.

There is also significant international movement to follow the U.S. lead by opening 5 GHz unlicensed spectrum to keep up with rising consumer, enterprise and operator demand:

• The United Kingdom recently moved to open the 5.725-5.85 GHz band for broadband fixed wireless access (BFWA) under a very lightly licensed regime.
• India is studying opening 5.47-5.725 GHz for RLAN operation, and for the first time permitting outdoor operations across the 5 GHz band.
• Canada harmonized technical rules for the 5.15-5.25 GHz band with the U.S. regulations for unlicensed National Information Infrastructure devices.

Significant harmonization exists between mid-band spectrum policies under consideration in the U.S. and internationally. The 3.7-4.2 GHz band includes, or is near to, a number of globally standardized, 5G-designated bands.

On October 2, 2017, Ericsson responded to the United States FCC Inquiry on mid band spectrum focusing on 3.7-4.2 GHz, 5.925-7.125 GHz, and 7.125-8.5 GHz.

Mark Racek lead the Ericsson team to prepare the response to the FCC.

Ericsson asked the FCC to:

1) Pursue flexible-use licensed opportunities in the 3.7-4.2 GHz band using market-based mechanisms to clear that spectrum;

2) Explore the introduction of new licensed opportunities in the 6.425-7.125 GHz bands;

3) Pursue unlicensed opportunities in the 5.925-6.425 GHz with an emphasis on rules that render the band neutral to choice of technology;

4) Ensure that incumbent fixed service point-to-point operations in the 5.925-6.425 GHz and 6.425-7.125 GHz bands are protected from harmful interference;

5) Examine whether to transition the 7.125-8.5 GHz band from an exclusive federal band to a shared one; and

6) Adopt changes to existing long-haul backhaul rules to better support, next-generation, high-throughput services.
