Key facts
- The FCC is proposing to open unlicensed Bluetooth and Wi-Fi spectrum for direct satellite communications.
- This would allow standard consumer devices with unmodified chips to transmit signals directly to satellites.
- The proposal aims to expand Internet of Things (IoT) connectivity.
- Strict controls on Power Flux Density (PFD) and beam-steering are included to mitigate interference.
- A public comment period is open, with a vote on the order scheduled for September 30.
The Federal Communications Commission (FCC) is moving to open additional wireless spectrum for space-based broadband services, including unlicensed Bluetooth and Wi-Fi bands. The proposal, set for a vote on September 30, aims to significantly boost capacity for satellite internet to homes, in-flight, and on-ship connectivity, as well as for satellite ground networks.
This regulatory initiative seeks to address spectrum scarcity and expand global Internet of Things (IoT) connectivity. It establishes a framework allowing non-geostationary orbit (NGSO) satellite operators to utilize the 2.4 GHz unlicensed spectrum without requiring exclusive allocations or specialized terrestrial hardware. This means standard consumer devices with unmodified Bluetooth chips could transmit signals directly to orbit.
The FCC's proposal includes measures to mitigate interference between space-based receivers and existing terrestrial Wi-Fi and Bluetooth networks. These include strict orbital Power Flux Density (PFD) limits and mandates for spatial filtering and beam-steering on satellite payloads. The rules extend authorization to both short-range Bluetooth protocols and wideband 2.4 GHz Wi-Fi standards.
This move is expected to lower capital requirements for mass-market direct-to-device deployments, complementing existing frameworks. Companies like Hubble Network and Spire, which have previously received waivers for similar spectrum use, could benefit from a formalized rule. Commercial space stations, such as those planned by Vast, could also see streamlined approvals for onboard devices.
However, potential challenges include interference concerns for existing Wi-Fi and rural broadband links, and possible opposition from existing direct-to-device (D2D) operators who have paid for spectrum rights. Radio astronomers also expressed concerns about increased traffic at 2.4 GHz potentially disrupting sensitive observations.
The FCC has opened a public comment period, with initial industry feedback expected before a final vote. Formalized rules are anticipated to be in place about a year or more after the comment period concludes.
