doc.: IEEE 802.11-25/0013r0 January 2025 Bluetooth SIG January 2025 Update Date: 2025-01-15 Authors: Name Company Address Phone email Rich Kennedy Bluetooth SIG Kirkland, WA +1-737-202-7014 rkennedy@bluetooth.com Submission Slide 1 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-25/0013r0 January 2025 Abstract HAPPY NEW YEAR 2025! This is an update on Bluetooth SIG actions and plans for optimized sharing the 5 and 6 GHz bands with incumbents and unlicensed/license-exempt devices. Submission Slide 2 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-25/0013r0 January 2025 Agenda Bluetooth Sharing Goals The Overall Bluetooth SIG Plan Recent Actions Bluetooth Next Steps Submission Slide 3 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-25/0013r0 January 2025 Bluetooth Sharing Goals The Bluetooth SIG recognizes the contribution the Wi-Fi industry has made in opening the 6 GHz band for unlicensed/license-exempt sharing to grow the technology Today, Bluetooth technology needs to secure its future growth The 83.5 MHz of the 2.4 GHz band is not a sufficient hedge against congestion or sufficient to support innovation Bluetooth and Wi-Fi successfully shared the 2.4 GHz band for many years Unfortunately, most of 5 GHz is not viable for Bluetooth, i.e., indoor restrictions and DFS 5.8 GHz band available in many regulatory domains Narrowband technology already deployed in U-NII-3 The 6 GHz band has room for Bluetooth and Wi-Fi, and there is time to develop optimal sharing mechanisms We will work closely with the Wi-Fi industry in IEEE 802 and ETSI BRAN to enable Bluetooth sharing these band equitably Submission Slide 4 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-25/0013r0 January 2025 The Overall Bluetooth SIG Plan Leverage the Bluetooth SIG Regulatory Expert Group to drive regulatory and standards changes just as Wi-Fi did Including companies with both Wi-Fi and Bluetooth businesses Collaborate with Wi-Fi industry to drive needed changes Work with SDOs to develop optimum spectrum sharing methods and advance regulatory/standards to codify them as required ETSI BRAN New Work Item adopted in September 2023 (BRAN #120) Draft text for EN 303 687 (Clause 4) was proposed in September 2024 (BRAN #125) ACCEPTED in December (BRAN #127) FCC Petition for Rulemaking needed to increase PSD limit for all VLP devices -5 dBm/MHz was a conservative initial approach for permitting VLP devices* *FCC 23-86 Second Report and Order paragraph 50 Submission Slide 5 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-25/0013r0 January 2025 The Overall Bluetooth SIG Plan [2] The detailed plan can best be developed working together Now that the FCC has completed the two rounds of VLP decisions, we are requesting another for narrowband sharing Chairwoman Rosenworcel said there will be a number of additional NPRMs New Chair, Brendan Carr (1/20/2025) appears to be supportive of unlicensed in 6 GHz In August 2024 meeting, OET Deputy Chief suggested we bring a Petition for Rulemaking (PfR) Interference analysis, narrowband into incumbents may be needed Bluetooth SIG is working to fulfill these requirements Wi-Fi also wants better VLP PSD limits Should we bring a combined petition? Submission Slide 6 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-25/0013r0 January 2025 Recent Actions Continued work on technical proposal for ETSI BRAN The Bluetooth SIG text submission for NB channel access with LBT Accepted for EN 303 687 A few TBD parameters still need to be finalized in February 2025 (BRAN #128) FCC strategy in process FCC shifting back to Republican control; timing of NPRM activities uncertain; Net Neutrality the focus again Discussing OET plan in the interim Submission Slide 7 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-25/0013r0 January 2025 Bluetooth Next Steps ETSI BRAN #128 February 3 - 6 Complete draft text for EN 303 687v2.1.x and begin the approval process ETSI ERM TG11 February 6 - 7 Work on 5-year revision of EN 300 328 ETSI ERM TG28 Work on 5-year revision of EN 300 440-1 Bluetooth to operate as an SRD in the 5.8 GHz band in the EU Submission Slide 8 Rich Kennedy (Bluetooth SIG)
