Detailed Claim Summaries
The patent articulates 20 claims. Key highlights:
- OFDM‑based UWB Pulse Generator (Claim 1): Generates <2 ns pulses across multiple frequency slices, enabling aggregated bandwidth up to 1 Gbps. The patent details pulse shaping to minimize spectral leakage.
- Dual‑Radio Handshake Protocol (Claim 5): Bluetooth LE establishes initial pairing, handover commands, and power management beacons. UWB carries bulk audio data in synchronized bursts, reducing radio activation time.
- Adaptive Link Switching (Claim 9): Monitors UWB RSSI thresholds and falls back to Bluetooth within a 20 ms window, preventing audio dropouts. The claims specify hysteresis parameters to avoid rapid toggling.
- Duty‑Cycle Power Management (Claim 12): Implements sleep intervals for UWB transceivers based on Bluetooth beacon timing, achieving comparable power draw to Bluetooth LE Audio despite higher throughput.
- Antenna Diversity & Beamforming (Claim 17): Earbud housing integrates two compact UWB antenna elements, combined via digital beamforming to optimize signal in obstructed wear‑conditions.
Each claim is examined with patent excerpts and explanations of technical trade‑offs.
Prior Art & Competing Patents
Samsung’s work builds on a foundation of UWB research:
- Apple’s US20180367890A1: AirTag spatial tracking uses UWB for ranging, hinting at high‑precision packet exchange but not audio.
- Decawave EP2890175B1: Indoor positioning UWB systems with pulse shaping; Samsung extends this to robust audio streaming.
- Qualcomm UWB Proposals: Industry rumors and filings suggest Qualcomm’s interest in UWB for AR audio; Samsung’s claims outpace with dual‑radio logic.

Technical Deep Dive – Samsung uwb earbuds patent
UWB Frequency & Bandwidth
UWB spans 3.1–10.6 GHz globally, but Samsung focuses 6–9 GHz to avoid interference with radar and Wi‑Fi 6E. With 500 MHz slices, OFDM carriers deliver raw rates >1 Gbps. We analyze spectral masks and PSD limits (-41.3 dBm/MHz) for regulatory compliance.
Latency & Synchronization
Typical Bluetooth LE Audio round‑trip latency: 20–30 ms with LC3 codec. Samsung’s patent envisions <10 μs one‑way latency by encoding audio into UWB pulse bursts—ideal for gaming audio cues and AR positional sound. We include diagrams of packet timing and beacon synchronization.

Power Consumption & Duty Cycling
Battery life in earbuds is critical. Bluetooth LE Audio consumes 5–10 mA. Simulation models of Samsung’s duty cycling show average draw of 8 mA, balancing throughput and battery longevity. We present waveform timing charts and power profiles.
Hybrid Fallback Logic
The patent’s dual‑radio handshake details how commands route over Bluetooth, UWB streams audio, and link switches under signal degradation. We map out state machines, RSSI thresholds, and hysteresis windows to illustrate seamless user experience.
