Indoor tracking in industrial environments often requires very precise localization. For this purpose we offer solutions based on the short-range radio technology Ultra-wideband UWB. It does not work with consumer standards such as Wi-Fi and Bluetooth Low Energy, but offers an accuracy better than 30 cm. Indoor positioning with Ultra-wideband has some significant advantages: The accuracy is cm, which is considerably better than when working with beacons meters or Wi-Fi meters.

Height differences can be measured accurately.

However, the technique is a special solution which requires appropriate components and thus is mostly suitable for special industry applications. Ultra-wideband is a short-range radio technology which can be used for indoor positioning. This method measures the running time of light between an object and several receivers anchors — infsoft Locator Nodes. For the exact localization of an object at least 3 receivers are necessary trilateration.

Also, there must be direct line-of-sight between receiver and transmitter.

The object to be tracked asset is equipped with a small tag infsoft Locator Tag which runs on battery power or draws its power via a forklift, for example. The nodes have a fixed position in the infrastructure and can use the running time of light to calculate the distance of the asset.

Combining the data of 3 Locator Nodes or more results in a positioning accuracy of cm. In order to localize assets, the infsoft Locator Tag measures the distance to several infsoft Locator Nodes and sends the data back to them.

Here, the position is displayed for example on a map. If the positioning data should be immediately displayed on a mobile device smartphonethe infsoft Locator Tags can communicate with the smartphone via Bluetooth or USB interface directly.

Time of Flight is measured, just like explained above, but the Locator Tag exchanges the data with the device via Bluetooth or USB port. Within server-based installations, positioning happens there. More info on infsoft Locator Nodes. It runs on batteries and transmits data for positioning to the infsoft Locator Nodes. More info on infsoft Locator Tags.

Here are some examples:. In a warehouse or production facility, work equipment such as forklifts can be tracked with high precision. The analysis of routes — i. Assets in extensive warehouse systems such as pallets can be recorded and their location, service life and movement history can be retrieved. With asset tracking, it is possible to prevent wrong deliveries or incorrect inventories.

Punctual production supply in production industries can be facilitated by applying a tracking system for tugger trains and a machine learning system.This opens up new opportunities in several business verticals, that have simply not been possible before. Due to the nature of the signals, UWB pulses can be distinguished even in noisy environments, plus the signals are resistant to multipath effects. All of these traits give UWB big advantage over traditional narrowband signals in case of ranging capabilities.

Also due to the strict spectral mask, the transmit power lies at the noise floor, which means that UWB does not interfere with other radio communication systems operating in the same frequency bands. By implementing RTLS UWB for controlling of intralogistics and machine flow based on their real-time position solution thus can reduce operational time and thus to significantly increase the performance of manufacturing and process flow.

Due to more exact and accurate data representation, Digital Twin of real production can be delivered. Demonstration or testing thus can be done almost immediately. If you want to extend area, just add more Anchors, it is simple.

Have any questions? Just contact us! The positioning error cumulatively increases, need to use high quality sensors, only relative positioning available.It is IEEE It has been designed to counter all logical-layer and physical-layer distance modification attacks and can be configured to ensure different degrees of security while providing su cient amount of distance measurements to be run in a single session. Any microcontroller being able to provide random number generation and authentication routines is suitable to drive 3db UWB IC.

The core of 3db's innovative secure distance measurement technology is the use of Ultra-Wide Band UWB signaling in order to deliver ultra-low power and provably secure technology from the logical layer down to the physical layer. Such RF pulses allow maximizing the energy per pulse at the Transmitter which is crucial since it allows to reduce the complexity of the Receiver for a given distance range. Receiver power consumption reduces significantly owing to a decreased on-chip processing obtained by significantly less pulses to process for a given distance range.

This automatically translates into less complexity and silicon size. The measured time-of-flight can either be one way time-of-flight or a round-trip time-of-flight. One way time-of-flight measurement requires the clocks of the measuring entities to be tightly synchronized. The round-trip time is the time elapsed between transmitting a ranging data packet and receiving a response. The advantage of round trip time is that it enables any two devices to measure the distance between them without any help of external infrastructure.

Furthermore this allows ad-hoc network creation and self-localization. The figure above illustrates a round-trip ToF distance measurement between two devices also often referred to as 2-Way ranging. The precise distance measurement largely depends on the ability to estimate the time-of-arrival and the physical characteristics of the radio frequency signal itself.

Given that the ranging precision is directly proportional to the bandwidth of the RF signal, IR-UWB signaling with signal bandwidths larger than MHz is the best approach to achieve highly accurate real-time RF-based distance measurement. Using more measurements and filtering techniques allows achieving centimeter-precision accuracy.

They are proven to be only viable solution again Relay attacks.

Audio amplifiers shut out the noise for earbuds. LNA provides 24 dB gain with noise figure of 5 dB. Chip terminations offer broadband performance up to 67GHz. Cost efficient modular 2-port VNAs perform at Oscillator enables frequency offering up to MHz.Ultra-wideband also known as UWBultra widebandultra-wide band and ultraband 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.

Most recent applications target sensor data collection, precision locating [2] and tracking applications. Unlike spread spectrumUWB transmits in a manner that does not interfere with conventional narrowband and carrier wave transmission in the same frequency band.

Regulatory settings by the Federal Communications Commission FCC in the United States intend to provide an efficient use of radio bandwidth while enabling high-data-rate personal area network PAN wireless connectivity; longer-range, low-data-rate applications; and radar and imaging systems.

Pulse repetition rates may be either low or very high. On the other hand, communications systems favor high repetition rates typically in the range of one to two gigapulses per secondthus enabling short-range gigabit-per-second communications systems. This allows UWB to reap the benefits of relative immunity to multipath fadingunlike carrier-based systems which are subject to deep fading.

However, both systems are susceptible to intersymbol interference. UWB transmissions transmit information by generating radio energy at specific time intervals and occupying a large bandwidth, thus enabling pulse-position or time modulation. UWB pulses can be sent sporadically at relatively low pulse rates to support time or position modulation, but can also be sent at rates up to the inverse of the UWB pulse bandwidth.

Pulse-UWB systems have been demonstrated at channel pulse rates in excess of 1. A valuable aspect of UWB technology is the ability for a UWB radio system to determine the "time of flight" of the transmission at various frequencies. This helps overcome multipath propagationas at least some of the frequencies have a line-of-sight trajectory.

With a cooperative symmetric two-way metering technique, distances can be measured to high resolution and accuracy by compensating for local clock drift and stochastic inaccuracy. However, there is still multipath propagation and inter-pulse interference to fast-pulse systems, which must be mitigated by coding techniques. One performance measure of a radio in applications such as communication, locating, tracking and radar is the channel capacity for a given bandwidth and signaling format.

Channel capacity is the theoretical maximum possible number of bits per second of information that a system can convey through one or more links in an area. According to the Shannon—Hartley theoremthe channel capacity of a properly encoded signal is proportional to the bandwidth of the channel and the logarithm of the signal-to-noise ratio SNR assuming the noise is additive white Gaussian noise.

Thus, channel capacity increases linearly by increasing the channel's bandwidth to the maximum value available, or in a fixed-channel bandwidth by increasing the signal power exponentially. By virtue of the large bandwidths inherent in UWB systems, large channel capacities could be achieved in principle given sufficient SNR without invoking higher-order modulations requiring a very high SNR. Ideally, the receiver signal detector should match the transmitted signal in bandwidth, signal shape and time.

A mismatch results in loss of margin for the UWB radio link.

Channelization sharing the channel with other links is a complex issue, subject to many variables. Two UWB links may share the same spectrum by using orthogonal time-hopping codes for pulse-position time-modulated systems, or orthogonal pulses and orthogonal codes for fast-pulse-based systems.

Forward error correction — used in high-data-rate UWB pulse systems — can provide channel performance approaching the Shannon limit. Multipath interference distortion of a signal because it takes many different paths to the receiver with various phase shift and various polarisation shift is a problem in narrowband technology.

It also affects UWB transmissions, but according to the Shannon-Hartley theorem and the variety of geometries applying to various frequencies the ability to compensate is enhanced. Multipath causes fading, and wave interference is destructive. Some UWB systems use "rake" receiver techniques to recover multipath-generated copies of the original pulse to improve a receiver's performance.

Other UWB systems use channel-equalization techniques to achieve the same purpose. Narrowband receivers may use similar techniques, but are limited due to the different resolution capabilities of narrowband systems.

Ultra-wideband characteristics are well-suited to short-distance applications, such as PC peripherals. Due to low emission levels permitted by regulatory agencies, UWB systems tend to be short-range indoor applications. Due to the short duration of UWB pulses, it is easier to engineer high data rates; data rate may be exchanged for range by aggregating pulse energy per data bit with integration or coding techniques.

Conventional orthogonal frequency-division multiplexing OFDM technology may also be used, subject to minimum-bandwidth requirements.This document will be in force as of the publication date of Notice No. Upon publication, the public has days to submit comments.
