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 Wi-Fi Alliance to enable
Bluetooth sharing these band equitably

Slide 4
 
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 adopted in September 2023 (BRAN #120)
The detailed plan can best be developed working together
Now that the FCC has completed the first round of VLP decisions, we are
requesting another for narrowband sharing (without geofencing)
Chairwoman Rosenworcel said there will be a number of additional NPRMs

Slide 5
 
FCC 23-86
 
Second Report and Order
VLP Power Levels and Protection of Incumbents
Bluetooth SIG:
Support Wi-Fi conclusions on VLP power and PSD limits (14 dBm and 1 dBm/MHz); narrowband
less likely to cause harmful interference
CBP for protection of BAS and CARS not a concern for U-NII-5
Second Further Notice of Proposed Rulemaking
Power Limits for Geofenced VLP Devices in the U-NII-5 through U-NII-8 Bands
Bluetooth SIG:
Currently, Bluetooth does not natively have geolocation capability, but can share in multi-radio
devices via coordination with GPS
Narrowband operation may not pose harmful interference threat without geofencing
 
January 2024

Slide 6
 
FCC 23-86 [2]
 
Memorandum Opinion and Order on Remand
NAB request for dedicated 6 GHz spectrum for mobile services
Bluetooth SIG:
BAS and CARS only in U-NII-6 and U-NII-8, where Bluetooth has no current interest

Note 1: The mean e.i.r.p. refers to the e.i.r.p. during the transmission
burst which corresponds to the highest power, if power control
is implemented.
Note 2: 
Narrowband (NB) devices are devices that operate in channel
bandwidths below 20 MHz. NB devices also require a
frequency hopping mechanism based on at least 15 hop
channels to operate at a value of in-band power spectral
density (PSD) above 1 dBm/MHz.
Note 3: The appropriateness of this limit shall be subject to review by 31
December 2024. In the absence of justified evidence, a value of
-37 dBm/MHz shall apply from 1 January 2025
 
Techniques to access spectrum and mitigate interference that provide 
an appropriate level of performance to comply with the
essential requirements of Directive 2014/53/EU
 shall be used. Where relevant techniques are described in harmonised standards
or parts thereof the references of which have been published in the Official Journal of the European Union in accordance with
Directive 2014/53/EU, performance at least equivalent to the performance level associated with those techniques shall be ensured.
 
ETSI BRAN 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)

Slide 9
 
Recent Actions
 
Work on consensus response to FCC 23-86 Second FNPRM
Referencing the EC Directive and SE45/FM57 conclusions for narrowband VLP
Continued review of sharing simulation results
Began discussion of acceptable limits
 
January 2024
 
Rich Kennedy (Bluetooth SIG)
 
Slide 10
 
Bluetooth Next Steps
 
Pursuing FCC FNPRM follow-on for narrowband VLP NPRMs
Participating in and contributing to the ETSI BRAN development of
narrowband channel access mechanisms in 6 GHz
ETSI BRAN #123 February 2024
Exploring enhanced sharing mechanisms for the 5725 – 5850 MHz band
Further regulatory action needed on the 5.8 GHz band globally
China: Bluetooth type-approval requirements
Japan: 5.8 GHz band limited by DSRC Road Tolling – can VLP share?

Bluetooth SIG presents an update on their actions and plans for sharing the 5 and 6 GHz bands with incumbents and unlicensed devices. Recognizing the need for future growth, they aim to collaborate with the Wi-Fi industry to develop optimal sharing mechanisms in the 6 GHz band. Their plan includes creating an industry coalition, collaborating with SDOs, and driving regulatory and standards changes to facilitate equitable spectrum sharing.
