Others applications are emerging
Regarding other interesting tools that are starting to adopt UWB, are the burglar stands, usually adopted as anti stolen tools for exposition of goods in shops, department and shopping mall, as well as in the exhibitions.
DFS Technology introduced wireless burglar stands for smartphones/tablets using UWB connectivity, replacing traditional wired/2.4 GHz systems. These stands, priced at $68 on Alibaba, offer enhanced anti-theft security and are ideal for electronics stores and trade shows. Each stand includes two UWB modules for tag-to-tag communication.
RTLS reduces installation cost and easing regulation
RTLS UWB adoption is maturing year by year, however, one of the most struggled issues addressed by the RTLS system integrator is related to the installation and the related labours hours that is necessary when a RTLS system is installed into a specific location. Omlox open standard aiming to mind the gap in terms of interoperability among UWB systems.
On the market there are several type of UWB measurement techniques that are implemented for avoiding increasing in installation time and total cost.
Ubitraq, a Chinese system integrator, has patented a UWB system with UWB AoA anchor. UWB-AoA solutions offer a more cost-effective alternative to traditional UWB RTLS by reducing the need for extensive infrastructure. Unlike ToF (Time of Flight) and TDoA (Time Difference of Arrival) systems, UWB-AoA operates with fewer base stations, lowering deployment density and simplifying installation. It provides higher accuracy and broader coverage than Bluetooth AoA, with a typical coverage radius of 20 meters and accuracy within 1 meter. This reduces costs in two main areas: fewer base stations required and easier, less specialized labour installation, making it a convenient and affordable option for enterprise markets.
China's high demand for RTLS
In China, RTLS systems deployment was mandatory in several municipalities, in particular UWB RTLS systems are preferred due to ensure safety in sectors like coal mining, chemical plants, tunnels, and prisons facilities by accurately tracking personnel. With IoT integration, UWB technology supports efficient management across industries such as medical, manufacturing, and public security.
Chinese UWB chip OEMs could gain market share once they reach precise measure distance, strong interoperability and cost performance. For example, in recent times, Woxu Wireless, a partner of Qorvo, has started to shift to MK Semi chip for a new E-ink display positioning tags and personnel tracking solutions for Industrial IoT, mining, and tunnel environments.
UWB regulation changed for EU and China
On April 29, 2024, China's Ministry of Industry and Information Technology issued a new "Interim Provisions on Radio Management of UWB” which is to come into effect on August 1, 2025. These regulations define RF requirements and open the 7163MHz to 8812MHz frequency range for UWB technology, supporting channels 8, 9, 10, and 11, including large bandwidth modes. This development facilitates high-precision positioning and radar perception.
The new Chinese regulations encourage UWB development by efficiently utilizing spectrum resources, balancing coexistence with 5G/ next 6G, and opening new market opportunities. This emphasizes future growth, promoting advanced UWB applications and supporting domestic chip manufacturers.
Supporting the large bandwidth mode significantly improves ranging accuracy and radar perception, boosting UWB's performance in various applications.
Recently, not only China revised the regulation band for UWB, also Europe revised the spectrum allowance. The new EU regulation (2024/1467), issued on May 27, 2024, introduces significant updates for UWB technology in location-based services. One major change is the increase in transmission power for indoor UWB locators by 10 dB, from -41.3 dBm/Hz to -31.3 dBm/Hz. This change could extend the range/penetration between the anchor/tag communication. Thanks to this regulation the deployment of a UWB RTLS system could reduce infrastructure costs and increase ROI by requiring fewer anchors, thanks to a major signal coverage across the designated area.
The regulation also harmonizes the use of UWB outdoors across the EU, allowing for easier deployment of UWB CH5-CH9 (6 GHz to 8.5 GHz) without the need for country-specific approvals. Previously, outdoor UWB use was restricted and approval processes varied by country. These changes enhance the ecosystem of location services, with EU countries required to implement these measures by the end of 2024.
UWB RTLS applications often utilize lower frequency channels because they offer the greatest range, minimizing the necessary infrastructure for an installation. However, future systems are expected to incorporate UWB channel 9, particularly in regions like Japan and South Korea. Additionally, the use of UWB channel 5 has faced challenges since WiFi (WiFi 6 and WiFi 7 in particular) began operating on the same frequency, causing interference with UWB systems.
2023 and 2024 main UWB RTLS development solutions
KDDI's upcoming demonstration at the "KDDI Museum" in Tokyo showcases the potential of UWB in RTLS applications.

The system uses UWB sensors and smart tactile blocks to guide users via a smartphone app. Supported by a 1.3 billion KRW government investment, the technology aims for swift implementation to enhance independent mobility for the visually impaired.
GNSS+UWB an increasing trend
Ubisense has launched the Dimension4 RTK-Tag, which innovatively combines UWB and signal-corrected RTK-GPS technologies. This dual-technology approach offers precise asset tracking with up to 5cm accuracy across both indoor and outdoor environments. By merging UWB's exceptional indoor performance with RTK-GPS's outdoor precision, Ubisense addresses critical operational challenges in mass transit and heavy manufacturing, such as space constraints and complex fleet maintenance. This development signifies a major advancement in real-time location systems (RTLS), reducing hardware requirements and enhancing efficiency. The Dimension4 RTK-Tag, already deployed in the US and UK, exemplifies the future of integrated tracking solutions, promising significant returns on investment and operational improvements.
Several companies have started to develop UWB + GNSS hybrid solutions, as the demand from the market to monitor both inside and outside assets and the labor force is rising. For instance, Kunchen (a Chinese RTLS system integrator) implemented a GNSS+UWB infrastructure for continuous tracking of Advanced Driver Assistance Systems (ADAS) in non-open-sky settings such as tunnels and indoor parking facilities that was already operatives in 2021. In the automotive sector, which prioritizes redundancy, a high-precision GNSS receiver coupled with an Inertial Measurement Unit (IMU) and Real-Time Kinematics (RTK) has been widely embraced. However, for indoor/outdoor asset tracking, a combination of GNSS with sub-meter precision for outdoor tracking and Ultra-Wideband (UWB) for indoor environments could be enough, especially considering that centimeter precision is often specifically required for indoor use cases and not for all external logistic tracking routes.
