UWB Mobile Kit N1
📦Kit Contents and Setup
How does the Mobile Kit work?
The Mobile Kit connects a smartphone with three or more anchors to measure precise location.
The smartphone uses BLE to find and connect to nearby anchors
Once connected, it uses UWB to receive real-time distance and direction data
You can also process the data directly in your app using the Android / iOS SDK
Since the smartphone controls the system, setup is simple and testing can start right away
When can I use the Mobile Kit?
The Mobile Kit is useful when you want to test RTLS quickly or run indoor location-based experiments without complex setup.
Common use cases:
Hands-on practice for training or workshops
Collecting location data in a lab
Testing prototypes during app development
Analyzing indoor asset movement paths
It is especially suitable for short-term tests or proof-of-concept (PoC) projects.
What kind of environment is best for the Mobile Kit?
The Mobile Kit works reliably in indoor environments with power supply.
Recommended environments:
Offices, classrooms, or labs with stable power
Open indoor areas with low wireless interference
※ Anchors require a wired power connection.
How accurate is the positioning?
Indoors, you can expect an accuracy of within ±30 cm. The actual accuracy may vary depending on the environment and installation, but it is precise enough for typical testing and practice purposes.
What is included in the Mobile Kit?
Inside the box, you’ll find:
4 Mobile Anchors
4 USB-C power cables
SDK documentation
This basic set lets you start RTLS testing in small indoor spaces without buying anything extra.
※ Depending on your use case, you can add more anchors or expand the SDK sample code.
🔧Integration and Development
Can I connect the Mobile Kit to my app or service using the SDK?
Yes. The Mobile Kit can be easily integrated into your own app or service using the GrowSpace SDK.
The GrowSpace Android SDK combines BLE and UWB-based indoor positioning in a single package.
It provides a simple interface using one main class: SpaceUwb.
Main features of the Android SDK:
BLE + UWB distance measurement (Ranging)
RTLS-based position calculation (x, y, z coordinates)
Real-time detection of device connection and disconnection
Which platforms are supported (Android, iOS, etc.)?
The Mobile Kit supports multiple platforms to work across different operating systems.
Android → The official GrowSpace Android SDK is available. It integrates BLE + UWB ranging and positioning into a single class called
SpaceUwb.
iOS → Integration is available using Swift-based BLE communication. Example code is provided for receiving location data and real-time monitoring.
Which smartphone models are compatible with the Mobile Kit?
Only smartphones with built-in UWB functionality are supported. Some models may not support direction (azimuth, elevation) data, depending on the device.
✅ Android Devices
Most Galaxy Plus or Ultra models support direction data. Some Google Pixel models are also compatible.
Supported models include:
Galaxy Note20 Ultra
Galaxy S21+ / S21 Ultra
Galaxy S22+ / S22 Ultra
Galaxy S23+ / S23 Ultra
Galaxy S24+ / S24 Ultra
Galaxy S25+ / S25 Ultra
Galaxy Z Fold2 ~ Z Fold5
Some Pixel models with UWB
For Galaxy S24+, direction data may not be fully supported. We recommend testing in advance. You can check compatibility directly in the app under [Check azimuth, elevation].
✅iOS Devices
Most iPhone 11 or newer (excluding SE models) automatically collect UWB direction data.
Supported models include:
iPhone 11 / 11 Pro / 11 Pro Max
iPhone 12–16 series (including Pro models, excluding SE)
UWB 지원 여부는 기기 제조사 사양 또는 RTLS 앱 메뉴에서 확인해 주세요.
How many smartphones can connect to one anchor at the same time?
One anchor can connect to up to 5–6 smartphones simultaneously. This means a single anchor can be used to measure the positions of multiple smartphones at the same time.
🔌Power and Usage Time
How long can the anchor run on a charge?
The anchors in the Mobile Kit (N1) do not have built-in batteries and are not rechargeable.
They require a wired power connection to operate.
They only work when connected to a power source, so they must be used in indoor environments with electricity.
How is power supplied? Is it battery-powered or cable-powered?
Anchors in the Mobile Kit (N1) use a wired power connection via cable. They do not have built-in batteries, so they must be used in places with a power source.
Each anchor comes with one USB-C cable.
You can connect it to a USB power adapter (5V / 1A or higher) or a multi-port charger.
Smartphones run on their own batteries, so they don’t need separate power.
The Mobile Kit (N1) is easy to set up and supports long-term use, but it is not suitable for battery-powered or mobile operation.
※ The system may not work properly in outdoor environments where power is not available.
