Bluetooth SIG September 2023 Update on Spectrum Sharing Plans
Bluetooth SIG provided an update on their actions and plans for sharing the 5 and 6 GHz bands with incumbents and unlicensed devices. They aim to collaborate with the Wi-Fi industry to enable equitable sharing for Bluetooth, particularly focusing on the 6 GHz band. The overall plan includes forming an industry coalition, driving regulatory changes, and working with standardization bodies to advance spectrum sharing methods.

doc.: IEEE 802.11-23/1368r0 September 2023 Abstract This is an update on Bluetooth SIG actions and plans for sharing the 5 and 6 GHz bands with incumbents and unlicensed/license- exempt devices. Submission Slide 2 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-23/1368r0 September 2023 Agenda Bluetooth Sharing Goals The Overall Bluetooth SIG Plan Recent Actions ETSI BRAN #120 New Work Item Bluetooth Next Steps Submission Slide 3 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-23/1368r0 September 2023 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 The 83.5 MHz of the 2.4 GHz band and even 470 MHz (not contiguous) of the 5 GHz band were not a sufficient hedge against congestion or enough room for innovation Today, Bluetooth is in that same situation 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 Wi-Fi Alliance to enable Bluetooth sharing these band equitably Submission Slide 4 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-23/1368r0 September 2023 The Overall Bluetooth SIG Plan Create an industry coalition of Bluetooth companies 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 up for adoption in September (BRAN #120) The detailed plan can best be developed working together In the US, Bluetooth has asked the FCC to finish the current FNPRM supporting VLP, and start another for Bluetooth (narrowband) sharing Submission Slide 5 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-23/1368r0 September 2023 New Work Item Provisions (1) To develop a channel access mechanism for Narrowband Frequency Hopping equipment operation (2) To develop mechanisms enabling LPI client-to-client operations in accordance with ECC/DEC/(20)01 and EC Decision 2021/1067 on 6 GHz WAS/RLANs (3) To consider further development of FBE and LBE parameters for channel access mechanism (4) To consider inclusion of new channelization to support next generation technologies (bandwidths exceeding 160 MHz, e. g. 320 MHz) Submission Slide 6 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-23/1368r0 September 2023 Recent Actions Introduced a New Work Item for ETSI EN 303 687 to develop channel access mechanisms for narrowband technologies in the 6 GHz band Adoption must await final ENAP approval of the initial version EN 303 687v1.1.0 was approved on June 27, 2023 Will begin at BRAN #120 in September 2023 Submission Slide 7 Rich Kennedy (Bluetooth SIG)
doc.: IEEE 802.11-23/1368r0 September 2023 Bluetooth Next Steps Pursuing FCC FNPRM follow-on to FCC-20-51 Meetings with FCC in early October Participating in and contributing to the ETSI BRAN development of narrowband channel access mechanisms in 6 GHz Exploring enhanced sharing mechanisms for the 5725 5850 (5875) MHz band Further regulatory action needed on the 5.8 GHz band globally China Japan Submission Slide 8 Rich Kennedy (Bluetooth SIG)
