How does it work?

Ultra Wideband (UWB) Beacons are small, battery powered radio transmitters that are attached to walls or things.

Nearby devices that are UWB-enabled and have compatible apps connect to these beacons and compute precise distance and angle. Apps use spatial awareness data to deliver breakthrough experiences, such as location-based services, way-finding, contactless payments and more.

How does it work technically?

In addition to Bluetooth, modern smartphones and wearables transmit Ultra Wideband radio signals (often called UWB). They connect to compatible UWB beacons and tags and compute time-of-flight and inch-precise distance and direction.

Intelligent tiny computers

Each UWB beacon is a tiny, battery-powered computer. It has several radio modules such as BLE or UWB. It runs intelligent firmware that periodically transmits low-power BLE signals. It can run on small batteries for years.

Inch-precise ranging with UWB

Nearby devices with a compatible chip, e.g. the latest iPhone with the U1 or second-gen UWB chip, Android phones with UWB, pick up these BLE signals. Compatible apps on the phone start UWB ranging and estimate precise distance between the devices. Multiple antennas in the phone help to compute the angle of signals.

Building Apps with the SDK

The Estimote SDK for iOS and Android allows you to create applications that react to the proximity of many UWB beacons and tags at once. Our API lets you access both distance and angle of the nearby beacons. Telemetry data including battery status or motion is also available. On iOS ranging with UWB beacons is also possible in the background when app is closed.

What are the applications?

UWB beacons provide spatial awareness to the nearby phones. Mobile apps integrated with our SDK detect and range with beacons to provide indoor way-finding or automatically trigger actions when people enter  geofenced areas defined by installed beacons.

Ordering and shipping

UWB Beacons

Are Estimote UWB beacons compatible with the U1 and second-gen UWB chip and the Apple Nearby Interaction API?

Yes, our UWB beacons are equipped with the latest Ultra Wideband (UWB) chipset created by an Apple-certified manufacturer and compatible with UWB-enabled products (iPhones 11, 12, 13, 14, 15), as well as the publicly available Nearby Interaction API.

When will the Estimote UWB Beacons Dev Kit be shipped?

Dev Kits are ready to ship today. They typically arrive 1-3 days after they are ordered, depending on the region. We will charge your credit card once they have shipped and you will receive an email confirmation.

What is the battery life of a UWB beacon?

It really depends on how often phones connect to the beacons and “range” to compute the distance. Two AA batteries in the beacon can support 4,000 ranging sessions. Ranging twice a day gives the beacon one year of battery life.

Is it compatible with the Android?

Yes, our UWB beacons are following FiRa UWB communication standard which is also implemented on Android 12 with UWB-enabled devices (Google Pixel 6 Pro, 7 Pro; Samsung Galaxy Note S20, S21+, S22+, Z Fold 2, 3, 4). Android Core UWB API is currently available via Jetpack Library.

Do you ship internationally?

We ship anywhere in the world directly from our European facility. It might take a bit longer to deliver to regions where customs procedures are more complex (up to 10 days). Note that additional taxes or custom fees might apply as well.

What is the range of a UWB beacon?

The effective range depends both on the beacons and their orientation as well as device receiving the signals, eg. a smartphone. The average range for reliable ranging between our UWB beacon and iPhone is approx. 10 meters. But the signal can be also picked up from up to 30m as well.

What is the positioning precision?

For UWB tags which are in motion the accuracy will be approx. 10cm (4 inches). For BLE tags it can be 1 to 3 meters positioning precision depending on the room size.

Do you ship internationally?

Devices are manufactures in Europe where we ship from world-wide. Please note customs fees might and delays might apply in some regions.

How long does a battery last?

Inside each Beacon and Sticker is a non-rechargeable lithium battery. A beacon’s lifetime depends on its configuration. At default factory settings, Estimote Beacons last for about 2.5 - 3 years.

What is the coverage area of 4 anchors?

The line-of-sight range of UWB Anchors is approx. 20m, so the maximum coverage are 4 anchors can map is approx. 400m2. For largers space another set of achors should be installed.
