Ultra-wideband is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applications in non-cooperative radar imaging. Most recent applications target sensor data collection, precise locating and tracking.

UWB’s main attraction comes in the form of its extremely high location and directional accuracy. While radio technologies such as Wi-Fi and Bluetooth can provide location accuracy of a few meters, UWB is able to do so with an accuracy of 10 cm. This allows for UWB to be used in applications that require asset tracking while simultaneously providing device communication.
UWB stands for Ultra Wide Band and is used as a short-range wireless communication protocol to track the location of objects indoors. UWB works by calculating locations within less than half an inch by measuring how long it takes short radio pulses to travel between one device and another.
UWB technology enables accurate real-time tracking of the location of goods or people indoors. It can be used to significantly improve the efficiency and safety of e.g. a production or treatment facility or the trade sector.

Asset tracking is important because it allows companies to track their valuable property, even if they move from one location to another or from one property to another. Asset tracking helps companies to improve their operations, identify inventory losses and improve security.
Asset tracking is an integral part of the asset management strategy. It is the very important component which helps track, locate and monitor physical assets. In other words, it is the tools used and implemented to do it.
Asset tracking solutions can benefit any industry that handles assets or high-value inventory. Industries with critically supportive assets benefit the most, such as manufacturing, healthcare, oil and gas, mining, steel, telecom and pharmaceuticals.

In active RFID systems, the labels have their own power source which permits the label to transmit data continuously, making real-time positioning possible. It gets up to 3 meters (or 10 feet) precise, whereas ultra-wideband technology has an accuracy of 10-30 cm (4-12 inches).
The propagation of UWB signals through walls is a crucial factor in determining the success of UWB radar technology. UWB signals, when propagating through walls, not only suffer attenuation but also distortion due to dispersive properties of the walls.
UWB devices do not interfere with Wi-Fi transmitters or receivers. The smooth functioning of the UWB signal is a huge factor in safety and reliability in locations with accurate measuring devices, such as hospitals or the electronics industry. The UWB operates outside congested ISM bands and does not interfere with or cause interference to other radio signals.
Its high data rate and low latency enable real-time communication and control between machines and systems. UWB-based communication protocols ensure reliable and secure data transmission, enabling precise coordination and synchronization of automated processes.
Large amounts of data can be transferred much faster with UWB because it is spread over a wide bandwidth, which keeps the transmitter on for a much shorter time and significantly reduces power consumption. This means that with the same power consumption, UWB can transmit much more data. At moderate distances, the data transmission capacity is approx. 7 Mbs.
UWB can detect the location of a device over a range under 200 meters. However, it operates most effectively over short ranges, generally between 50-100 meters, and works best with line of sight between devices or anchors.

The Iiwari UWB tag is a small, lightweight and cost-effective tag with more than 2 years lifetime when the location signal is updated every 60 seconds & 1 time/s in motion including at least 6 hours of movement/day, 365 days/year.

UWB signals can pass through solid objects such as walls and floors, making it possible to track the location of objects or people even when they are hidden from view. This is not possible with BLE, which relies on line-of-sight communication.
Ultra-Wideband, in comparison, provides a much higher accuracy (up to a few centimeters). In contrast to Bluetooth Low Energy, the distance it measures is not based on the signal strength, but the time it takes the signal to travel from point A (UWB tag) to point B (smartphone/base station). In theory, the angle measurement (AoA) becomes more accurate the closer the devices are brought. Probably the consensus is that with a reasonable number of devices, UWB is more accurate, but Bluetooth is more general-purpose due to its generality and other measurements such as conditions, etc.

Apple Airtag and Samsung SmartTag+ also use UWB radio, but how are they different from Iiwari’s indoor positioning system?
From the point of view of location applications, Apple Airtag and Samsung SmartTag+ only connect to the mobile phone. They use a UWB radio and typically a time-of-flight algorithm to calculate the distance (and angle) between the phone and the tag and visualize the location of the tag relative to the phone, typically using some AR (Augmented Reality) method.
In addition, Samsung and Apple use the crowdsourced “Find my device” user network and GPS, Wi-Fi and other location-aware technologies from the user network’s phones to create and share tag locations among members using the “Find my device” application. The communication link for crowdsourcing functions between the tag and other phones is typically via the tag’s secondary Bluetooth radio.
So locally, the user of these tags gets the location of the tag with an accuracy of tens of centimeters relative to the phone. Global positioning accuracy, if the “Find my device” network can locate the device, is from a few meters to tens of meters.
In summary, positioning accuracy, latency and other important positioning KPIs in these networks cannot be pre-determined by Apple Airtag and Samsung SmartTag+.
Professional indoor positioning systems offered by Iiwari install an infrastructure of indoor positioning network devices in a given space and provide agreed performance to place tags in the space, including use case-defined and predetermined characteristics such as latency, accuracy, location update rates, etc. The positioning results can be used on any device, including mobile phones.

The total cost of ownership (TCO) of an RTLS system comes typically from anchor, tag, cabling and accessory HW, related installation and maintenance costs. In addition, the complementary analytics and other supporting SW offering might affect overall application cost. That said, the comparison of UWB system price to other technologies like BLE AoA RTLS system price is not straightforward.
If we compare anchors and related pricing, the BLE AoA’s (Angle of Attack) more complex antenna design might make them more expensive, but relatively the price of UWB radio chips makes the tag pricing a few euros in favor of BLE. In installation side, if we assume the current way of most BLE AoA and UWB technologies users using PoE for data and power supply, the difference is that for the BLE AoA system, you have to setup the anchor device direction in addition to the XYZ position in the case of the UWB anchor. Iiwari however applies wireless data channel to 80% of its devices, making the cabling and installation way faster and cheaper.
Maintenance costs are mostly related to each individual provider’s capability to provide robust devices in addition to the supporting diagnostics and maintenance software.
10 – 150 euros depending on the casing, added sensors and other capabilities and features.
