Unlocks Next-Gen Indoor Access & Mobility

DL-TDoA is live.

DL-TDoA is a next-generation UWB positioning technology based on downlink signals,
enabling precise indoor location without the need for tags.
Each device calculates its own position, allowing flexible infrastructure without relying on fixed hardware.

What is DL-TDoA

01 DL-TDoA’s cluster-based approach enables accurate indoor positioning of both people and assets — all
without physical tags — powered by next-generation UWB technology.

02 GeoSpace is a robust indoor positioning platform built on a proprietary DL-TDoA cluster architecture designed, developed, and commercialized for real-world deployments.

03 The system is designed to be compatible with smartphones from Apple, Samsung, Xiaomi and others. It is paving the way for a future where indoor positioning works seamlessly without dedicated tags, using only the phone in your hand.

04 This technology advances beyond traditional tag-based RTLS systems by enabling accurate and convenient indoor positioning using only a smartphone or portable device. It is applicable in locations such as subways, airports, unmanned stores, and secured areas.
In addition to location tracking, the platform supports various integrated functions. It can handle user identification, authentication, and interaction with payment and access control systems, all within a unified environment.

DL-TDoA based on UWB technology minimizes infrastructure requirements
while providing accurate and adaptable indoor positioning.

DL-TDoA can be easily applied to various access environments and improves
both user experience and operational efficiency.

Detection

BLE detects user approach

DL-TDoA Ranging

UWB performs precise location ranging

Authentication

Automatic authentication upon proximity

Payment

Payment is processed automatically after pass-through

Key Technical Advantage

DL-TDoA is a next-gen positioning engine that combines automatic cluster set-up, self-localization, and unified distance calculations for rock-solid indoor positioning.

Auto cluster Setup

After installation, anchors automatically organize themselves into optimized clusters without manual configuration.

Seamless Cluster Sync

Clusters stay time-synchronized with high precision, even without external timing devices.

Self-Localization Support

Each user device calculates its own position using nearby anchors.

Cross-Platform Compatibility

Works across Android, iOS, and embedded systems for maximum deployment flexibility.

Unified Ranging Block

Built on a universal positioning logic, it ensures consistent performance and smooth integration across all use cases.
