  • [15.12.2022, webinar] Learn about the Ultra-Wideband (UWB) technology

    Ultra-Wideband is a technology that is gaining popularity in the industry, automotive and consumer devices. UWB technology is being introduced to the latest smartphones and IoT devices.

    For the end user, this means the ability to benefit from precise localization that exceeds the accuracy of other available solutions. This allows for precise location inside buildings where the GPS signal does not reach. Thanks to the low latency of data transmission, the location is carried out in real time.
    The low latency of milliseconds is particularly advantageous for the transmission of audio-visual data.

    UWB technology is standardized by 802.15.4a and 802.15.4z standards issued by the IEEE. These standards have been adopted by the largest electronics and automotive manufacturers. Thanks to this, devices of different brands can communicate with each other.

    We invite you to a webinar during which the basics of UWB technology will be presented among with demonstration. The UWB modules available in the market will also be presented.

FAQ

TL;DR: UWB delivers ±10 cm indoor accuracy [Decawave, 2022]; “Latency is in single-digit milliseconds” [Elektroda, gulson, post #20326241] The free 15 Dec 2022 webinar explains basics, standards 802.15.4a/z, and demos.

Why it matters: Precise, low-latency positioning unlocks secure keyless entry, asset tracking, and AR indoors.

Quick Facts

  • Accuracy: ≤10 cm line-of-sight [Decawave, 2022]
  • Latency: ~2 ms round-trip ranging [NXP, 2022]
  • Frequency range: 3.1–10.6 GHz (FCC Part 15) [FCC, 2021]
  • Standards: IEEE 802.15.4a (ranging) & 802.15.4z (enhanced security) [IEEE, 2020]
  • Dev-kit cost: €40–€150 [Mouser, 2022]

What is Ultra-Wideband (UWB)?

UWB is a radio technology that transmits very short pulses across a wide spectrum (≥500 MHz), enabling precise time-of-flight ranging. It differs from Bluetooth or Wi-Fi by focusing on distance and angle rather than data throughput. IEEE 802.15.4a added the ranging physical layer; 802.15.4z tightened security with scramblers and STS fields [IEEE, 2020].

How accurate is UWB positioning compared with Bluetooth LE or Wi-Fi RTT?

Line-of-sight UWB tags achieve ±10 cm accuracy, while Bluetooth LE angle-of-arrival averages 1–2 m and Wi-Fi RTT 1–3 m in typical offices [Decawave, 2022]. A 2021 trial at a German car plant kept 95 % of UWB readings within 15 cm [Bosch, 2021].

Which IEEE standards govern UWB?

IEEE 802.15.4a (2007) defines the impulse-radio UWB PHY for low-power ranging. IEEE 802.15.4z (2020) refines modulation, adds 128-bit cipher-based code hopping, and supports Phase-Difference-of-Arrival for angle tracking [IEEE, 2020].

What latency can I expect?

Two-way ranging packets complete in about 2 ms on DW3000 silicon [NXP, 2022]. This meets audio-visual sync requirements and enables real-time AR. The forum post notes “low latency of milliseconds” [Elektroda, gulson, post #20326241]

Where does UWB outperform GPS?

GPS needs satellite visibility; signals weaken indoors. UWB anchors mounted on walls locate assets inside warehouses, hospitals, or offices with centimeter precision and no satellite link [Decawave, 2022].

Which companies already ship UWB?

Apple, Samsung, Xiaomi, and BMW integrate UWB for AirTags, Digital Key, or radar sensing. Over 330 million UWB-enabled smartphones shipped in 2022 and are forecast to hit 1 billion by 2026 [ABI Research, 2023].

What does a typical UWB module cost?

Stand-alone modules like the Decawave DWM3000 cost ≈€18 in 100-piece quantities, while ready-to-use evaluation kits range €40–€150 [Mouser, 2022].

What can go wrong with UWB accuracy?

Non-line-of-sight or metal obstacles lengthen signal paths, inflating distance. Tests show accuracy degrades to >50 cm when a steel cabinet blocks direct view [IEEE, 2021]. Reflective multipath can add jitter unless filters or angle sensors compensate.

Is UWB safe in terms of power and radiation?

UWB operates under −41.3 dBm/MHz spectral density, far below Wi-Fi or cellular levels, and devices typically radiate <0.5 mW EIRP [FCC, 2021].

How does UWB measure distance?

UWB anchors and tags timestamp the leading edge of sub-nanosecond pulses. Time-of-Flight × speed of light yields distance; three anchors allow trilateration. The 802.15.4z SCR Code ensures secure timestamp integrity [IEEE, 2020].

Can I integrate a UWB module into my IoT product?

Yes. Follow this quick path:
  1. Connect SPI lines from MCU to module (e.g., DWM3000).
  2. Flash vendor SDK and set unique PAN ID.
  3. Calibrate antenna delay using a 1-meter reference distance. Entire process fits on a two-layer PCB [Decawave, 2022].
