Applications

Asset Tracking

Use UWB tags to track machines and equipment on vast factory floors to maximize efficiency and reduce costs. UWB can help factories track the location and movement of valuable assets, such as tools, machinery, and inventory in real time. This enables efficient asset utilization, reduces downtime, and enhances inventory management.

Indoor Navigation

Users can access maps on their smartphones or navigation devices powered by UWB. These highly accurate indoor navigation services can guide people through hospitals, parking garages, and airports. These systems provides real-time guidance, including turn-by-turn directions, to their desired destinations.

Also Available: NanoUWB Antenna

The Nano UWB Series antenna is the first antenna which has been designed to operate with the Sera NX040 UWB module. Ultra-wideband (UWB) is a short-range, high bandwidth wireless technology which enables applications that require high-speed data transfer or for precise location tracking application. UWB transmits and receives signals across an exceptionally broad frequency range.

The Laird Connectivity NanoUWB antenna features a rigid printed circuit board (PCB) that supports UWB implementations. The adhesive backed antenna can be used in space sensitive applications with aesthetically pleasing integration and high durability.

FAQ

The Sera 040 DVK is not being recognised by Windows, where do I find dapi drivers?

Windows should natively support the Sera 040 DVK using CMIS-DAP v2 interface drivers that will appear in device manager under Universal Serial Bus  devices.

If in Windows device manager you see an error with CMIS-DAP v2 interface in other devices then it may be that you are using a USB hub or dock that is preventing Windows from properly identifying the Sera 040 DVK. In which case try plugging the DVK directly into a USB port on your laptop or PC and it should be discovered automatically

I am having problems installing pyocd for Python

At the time of writing there may be issues installing pyocd for Python 3.12. If you experience issues such as failing to build wheel for hidapi, try reverting to Python 3.10 or 3.11.

We have also seen issue where pyocd reports an error during install, requiring VS C++ build tools. Be sure to install the C++ build tools using the link in the error. If the C++ build tools install fail then try to temporarily disable virus checking (or consult with your IT department) as we have seen some antivirus block some VS scripts used during build tool installation.

Can I send data over the UWB channel using Laird's Sera NX040 UWB tag?

Data transfer over the UWB channel is not currently supported by NXP's firmware that is loaded to Laird's Sera NX040 UWB tag.

What kind of accuracy can be expected with the NX040, relative to two-way ranging?

Laird's NX040 has an accuracy of +/-10cm for two-way ranging.


How does UWB work?

The functionality of a UWB transmitter revolves around emitting billions of pulses (formerly recognized as "pulse radio") across an expansive frequency spectrum. Subsequently, a corresponding receiver deciphers these pulses into usable data by identifying a recognizable pulse sequence transmitted by the emitter. These pulses are dispatched at a rate of approximately one every two nanoseconds, contributing to UWB's capacity for real-time precision.

UWB exhibits remarkable energy efficiency, while its substantial bandwidth of 500MHz renders it well-suited for transmitting substantial amounts of data from a central device to peripheral ones, covering distances of up to around 30 feet. Nevertheless, unlike Wi-Fi, UWB does not excel in propagating through obstacles such as walls.

What is the difference between UWB anchor and tag?

UWB Anchors have stationary, predetermined positions registered within the positioning system. They receive signals emitted by UWB Tags. Multiple UWB Anchors capture signals from a single UWB Tag. The system records the time it takes for the signal to travel from the Tag to the Anchor (referred to as Time-of-Flight).

What is the difference between GPS and UWB?

GPS functions as a satellite-oriented navigation system, enabling the determination of a lost item's location over extended distances. On the other hand, UWB, a more recent wireless communication technology, utilizes an expansive bandwidth to furnish precise location details for items that have been misplaced in close proximity.

How far can UWB transmit data?

UWB offers a data-transfer capability with an effective range of up to 25 meters, outperforming its competitor Bluetooth technology, which provides an effective range of only approximately 10 meters.

Can UWB go through walls?

The successful implementation of UWB radar technology hinges on how UWB signals propagate through walls. These signals experience not only attenuation but also distortion due to the dispersive characteristics of the walls when passing through them.

What are the downsides of UWB?

UWB's precision is restricted to short distances, imposing a limitation on its capacity to be applied across a wider range of scenarios.

Is UWB the same as WiFi?

UWB systems exhibit the capacity to monitor a greater quantity of tagged assets across extended distances with heightened precision in comparison to Wi-Fi-based systems. While a Wi-Fi-based Real-Time Location System (RTLS) might ascertain the presence of your assets within a designated room, UWB systems excel in providing precise location details within that room for each individual asset.

Is UWB same as Bluetooth?

Ultra-wideband, often referred to as UWB, ultrawide band, or ultraband, constitutes a short-range wireless communication protocol that harnesses radio waves to facilitate seamless device-to-device communication. While bearing a resemblance to Bluetooth, UWB surpasses it in terms of precision, dependability, and efficiency.

What is UWB?

UWB, an abbreviation for Ultra Wide Band, functions as a concise wireless communication protocol for tracking object locations over short distances. Its operation involves pinpointing positions with ~5cm accuracy by gauging the time it takes for brief radio pulses to traverse between two devices.
