Expansion of the 6-GHz band for low-power devices proposed by Rosenworcel
The Federal Communications Commission (FCC) has proposed new rules to expand the use of very-low-power (VLP) icloud devices in the 6-GHz band. If adopted, these rules are expected to bolster a growing ecosystem of cutting-edge applications like wearable technologies and augmented and virtual reality.
The proposed Report and Order would permit VLP unlicensed devices to operate across 350 MHz of spectrum in the U-NII-6 (6.425-6.525 GHz) and U-NII-8 (6.875-7.125 GHz) portions of the 6 GHz band. The FCC Chairwoman, Jessica Rosenworcel, stated that opening up access to the airwaves without licenses makes it possible to innovate without permission and develop find my device low-power wireless technologies.
Initially, broadcasters opposed the use of unlicensed low-power devices in the 6-GHz band due to interference, particularly with wireless ENG tech. However, tech advances such as enhanced interference mitigation measures and changes in usage patterns have lessened opposition to low-power devices in the 6-GHz band.
The VLP devices would operate at the same power levels and technical/operational protections as those recently approved for the U-NII-5 (5.925-6.425 GHz) and U-NII-7 (6.525-6.875 GHz) bands. They would have no restriction as to where they may operate and would not be required to operate under the control of an automatic frequency coordination system.
The devices would employ a contention-based protocol, implement transmit power control, and be prohibited from operating as part of a fixed outdoor infrastructure. The FCC stated that its actions in the 6-GHz band for VLP devices provide greater flexibility while fostering unlicensed innovation.
The SBE issued a warning to broadcasters earlier this year regarding the commission's intentions to expand lowes device operations in the 6-GHz band. However, the FCC did not mention any potential opposition or concerns from broadcasters or other parties regarding the use of VLP devices in the 6-GHz band.
The FCC did not provide a timeline for when the new rules for VLP devices in the 6-GHz band would be implemented, if adopted. The commission did not specify any changes to the protections for incumbent licensed services that operate in the 6 GHz band.
The FCC's decision to expand unlicensed use between 5.925 and 7.125 GHz has already helped usher in Wi-Fi 6E and support the growth of the Internet of Things. The new applications are expected to help businesses, enhance learning opportunities, improve healthcare outcomes, and bring new entertainment experiences.
The FCC will present the proposals for expanding the use of ultra-low frequency devices in additional spectrum in the 6 GHz band in October 2023, as proposed by Jessica Rosenworcel. The commission's actions aim to foster innovation and technological advancement while ensuring minimal interference with existing services.
