What is UWB Technology?

UWB is a relatively short-range wireless communication protocol and way, compare to Bluetooth and WIFI, both belong to the radio wave transmission. The difference compare to Bluetooth or WIFI, UWB is a wireless carrier communication technology that uses a bandwidth of more than 1 Ghz. It does not use sinusoidal carrier wave, but using nanosecond class non-sinusoidal narrow pulse transmission data, so it occupies a wide spectrum. Because it is widely used in indoor positioning system, it has high precision and efficiency.

UWB was primarily for military and telemedicine monitoring in the early years, largely because of the high cost and big size. With the development of UWB technology, UWB began to be used in many electronic products, such as mobile phones, lots smart wearable device starts to carry out high-precision indoor positioning with UWB technology. UWB is more and more widely used in various IoT application scenarios.

How Does UWB Work?


UWB works in a straightforward way. It transmits data not by common continuous carrier wave, but by pulse signal. When an RF signal source is sent out, the receiving source receives the signal at a straight distance in the first place. By receiving the time stamp, the signal flight distance can be calculated. For UWB, all reflections are negligible, allowing it to pick up the first signals that arrive. Not only that, but you can get the phase difference, calculate the angle difference, and finally locate the relative position of the target at the receiving end by distance and angle

A UWB transmitter works by sending one billion pulses (UWB was formerly called “Pulse Radio”) over a wide spectrum of frequencies; then, the corresponding receiver converts the pulses into data by listening for familiar pulse sequences sent by the transmitter. Sending a pulse about every two nanoseconds helps UWB achieve its real-time precision.

UWB has extremely low power consumption, but high bandwidth (500mhz) is ideal for relaying large amounts of data from host devices to other devices up to about 30 feet away. Unlike Wi-Fi, however, it is not particularly good at transmitting through walls.

UWB Technical Principle:


Location Principles: TOF (time of Flight) , TDOA (time of arrival) , Aoa (angle of arrival)

• Adopt the most accurate radio location technology known: Ultra Wide Band (UWB)

• UWB is a radio wave with a physical property that is good for location because it:

(1) the pulse width is extremely narrow (1ns) , which is good for timing and positioning, and can resist multipath effect naturally

(2) it occupies a wide spectrum and can resist radio interference of fixed frequencies such as WIFI/Bluetooth

(3) low spectral power and no interference to radio signals such as WIFI/Bluetooth

UW VS AOA indoor location advantages and disadvantages:


In the future, 70% of IoT data will be related to location data, and a large part of it will need to be centered around location data for business operations. It can be said that the market for indoor positioning technology will have its own occasions, depends on who can master the main market positioning competition, such as positioning systems, Bluetooth, AOA, UWB technology. Facing these two big localization technologies, how should the application enterprise find the suitable technical plan?

UWB positioning system has excellent positioning accuracy, in the harsh environment can also meet the needs of precision, Bluetooth AOA not only good accuracy, ecology is also very mature, but more suitable for a simple office or shopping mall environment, more inclined to the actual indoor location navigation. The pros and cons are described as follows:


1. UWB positioning system accuracy is 2 times more than Bluetooth positioning system

Ideally, both UWB positioning systems and Bluetooth AOA positioning can achieve centimeter-level accuracy. UWB wireless transmission is achieved by sending and receiving extremely narrow pulses of nanoseconds or microseconds, bluetooth is based on AOA technology to locate. As a result, UWB’s ability to penetrate obstacles is stronger than Bluetooth’s in real-world scenarios, and UWB’s effective transmission distance is more than 10 meters, about twice as much as Bluetooth’s. UWB accuracy is at the centimeter level.

Because Bluetooth can not accurately measure distance, if using a Bluetooth AOA base station location can only assume that the tag height from the ground. At this point if the label is raised or down, positioning accuracy will have a large deviation.

2. Bluetooth positioning has advantages over UWB positioning system in operation and maintenance

As an example of base station in the same scene, the hardware devices in UWB positioning system, such as UWB base station, need active power supply and solar power supply when transmitting a large amount of position data, bluetooth AOA positioning in a battery can work for a long time, in the operation and maintenance of obvious advantages.

  • The label can be a Bluetooth AOA chip, and the label Bom Cost is lower than UWB solution.
  • The phone can be used as a tag to enable the need to add the Bluetooth AOA vendor specific code under the APP.

3. UWB location systems may cost more than Bluetooth AOA location systems

UWB positioning system applications UWB base station adjacent to two points in about 20-50 meters, if the occlusion will be more devices, and Bluetooth AOA positioning is subject to signal propagation distance, the base station adjacent to two points in about 6 meters. So for devices that are configured in terms of distance, the need for Bluetooth is even greater. But in the current market, UWB positioning systems require devices that cost more than Bluetooth, so in terms of construction costs and application scenarios, maybe Bluetooth costs less, but in terms of applications, uWB is more widely used. But as UWB technology continues to improve, the cost gap between the two will become smaller and smaller.

Because the AOA Bluetooth each location base station coverage area is small, the base station spacing is even similar to iBeacon a few meters. A Bluetooth AOA base station is placed on the ceiling. The area covered by each base station is circular and the area covered in the space is conical (with the base station as the apex and the ground as the bottom) . The higher the ceiling from the ground, the greater the coverage. But the technical limitations, to achieve sub-micron positioning accuracy, each Bluetooth AOA base station coverage is too small. According to the QUUPPA proposal, the radius of coverage of a single Bluetooth AOA base station is equivalent to the installation height.

That is, when the height of the base station is 3 meters, it can only cover a circular area with a radius of 3 meters. So if you want to locate indoor space coverage at a height of 3 meters (common office space height) , you have to deploy Base station at intervals of about 5 meters, and each base station also needs to be connected to the network. So if UWB accuracy is to be achieved using AOA, it may be very complex to deploy and won’t cost much more than UWB


4. Bluetooth AOA location is susceptible to interference

Bluetooth 2.4 ghz frequency band is not authorized frequency band, more vulnerable to interference. Wi-fi, Bluetooth, wireless mouse and other devices in the office may have an impact on location. UWB signals are very stable and can be accurately located in any scene, so UWB application scenarios will be more extensive.

5. Different scenarios

Bluetooth AOA localization is more applicable in civil scene such as hospital, shopping mall, parking lot, etc. . This kind of scene takes the user as the core, and pays more attention to the user’s experience in the scene, such as looking for a car, looking for a location, etc. . UWB positioning system is more suitable in the enterprise scene, such as factory, chemical industry, power plant, etc. . These scenes take the enterprise as the core, pay more attention to the safety and management of personnel, and require higher positioning accuracy, uWB is more suitable for a wider range of scenarios than Bluetooth, and ISMARCH already has a large number of cases in UWB scenarios, including 500 + real-world scenarios, helping the enterprise to achieve better development.

So, at present, UWB positioning system and Bluetooth AOA positioning technology have advantages and disadvantages of each other. With the development of UWB technology and the wide use of UWB in electronic products such as mobile phones, the base station layout and cost of UWB will be lower and lower, so the use of UWB will be more and more widespread.

Who is better at indoor positioning, RFID or UWB?

The increasing abundance of indoor scenes such as shopping malls, parking lots, restaurants, hospitals, hotels, convention and exhibition centers has increased people’s demand for fast navigation and convenient positioning, indoor location technology thus has a place. The development of indoor positioning technology makes up for the inaccuracy, low signal or even no signal in indoor application, and makes people’s daily life more convenient.

At present, in the mainstream indoor location technology, the radio frequency identification (RFID) and ultra-wideband (UWB) location technology are often compared from the aspects of security, anti-jamming and communication transmission distance. So What’s the difference between the two indoor location technologies? Which is the better indoor location technology?

Before comparing the substantial difference between the two, let us first understand the two indoor positioning technology positioning principles.

Radio frequency identification (RFID) , also known as RFID, is a technology that uses radio frequency signals for wireless communications to automatically identify targets, a fixed set of readers reads the characteristics of a target RFID tag without establishing mechanical or optical contact between the identification system and a specific target.

UWB positioning technology, also known as UWB indoor positioning technology, is a very low-power high-speed data transmission wireless communications technology, through pre-arranged, known location of the anchor node and bridge node, it communicates with the newly added blind node and uses triangulation or fingerprint location to locate the position.

From the above, we can understand that the positioning principle of the two is different. What are the concrete and substantive differences between the two indoor positioning technologies?


Radio frequency identification (RFID) localization technology is limited by the cheap computation and the low efficiency data, the transmission, the storage ability, is vulnerable to all kinds of security threats including the privacy question, the security is low. UWB indoor positioning technology, which uses spread spectrum and time hopping technology to meet the high Data transfer rate, can hide the signal better in the background noise, thus protecting communication, the probability of data being intercepted is low. Therefore, UWB indoor location technology has higher security under the same data transmission.

2.Noise immunity

In the application of RFID technology, the two adjacent antennas of two adjacent readers send the RF signal at the same time, so the anti-jamming is poor. Ultra-wideband (UWB) positioning technology uses time-hopping and spread spectrum signals. The system has a large processing gain. When transmitting, the weak radio pulse signals are scattered in a wide frequency band, and when receiving, the signal energy is restored, the spread spectrum gain is produced in the process of de-spreading, so it is not easily disturbed by other signals. Therefore, the UWB indoor positioning technology has stronger anti-jamming ability under the same code speed condition.

3.Communication transmission distance

Radio frequency identification (RFID) technology is often used in regional positioning, and it is suitable for short distance identification communication. UWB indoor positioning technology is suitable for long-distance communication. Therefore, under the same positioning requirements, UWB positioning technology has a longer communication transmission distance.

Summary: compared with RFID positioning technology, in security, anti-jamming, communication transmission distance, ultra-wideband positioning technology is better. Therefore, for indoor positioning, UWB positioning technology has significant advantages, is a more ideal choice.

What Is UWB Positioning System?

UWB indoor positioning technology is a brand-new communication technology, which is very different from traditional communication technology. It does not need to use the carrier in the traditional communication system, but transmits and receives the data by the extremely narrow pulse which has the nanosecond or below the nanosecond level, thus has the GHz magnitude bandwidth.

iSmarch UWB watch tracker banner
UWB Positioning System Introduction

Compared with traditional narrowband system, UWB indoor positioning system has the advantages of strong penetration, low power consumption, good anti-multipath effect, high security, low system complexity, and can provide accurate positioning accuracy. Therefore, UWB localization can be applied to indoor stationary or moving objects, as well as human location tracking and navigation, and can provide very accurate positioning accuracy. But the cost is expensive and the network deployment is complex.

UWB positioning technology is very different from traditional communication technology, it does not need carrier wave in traditional communication system, but transmits data by sending and receiving extremely narrow pulse with nanosecond or less, so it has a GHz bandwidth. UWB indoor positioning can be used in various fields of indoor precise positioning and navigation, including people and large items, such as valuables storage, mine personnel positioning, personnel positioning and so on.

iSmarch UWB watch UWB tracker (9)

UWB Positioning System Introduction

The demand for indoor location is also emerging: shopping malls, airports, stations and other crowded places: the need for efficient crowd monitoring and route analysis means to improve operational efficiency, tap commercial potential; Factory: need to achieve intelligent storage management, production process tracking, personnel location attendance, automatic tracking of goods, automatic inspection, to achieve cost reduction and efficiency.

However, UWB indoor positioning is still flawed, the drawback of UWB is the need to have a perfect positioning network, and at any positioning point requires the support of three positioning base stations, uWB location algorithm is based on three-point location, if the number of base stations reduced will greatly affect the accuracy of location. Secondly, the drawback of UWB is that it can not have obstacles blocking radio transmissions, and small obstacles do not have an impact because radio diffraction, but if complete shielding is involved, it can result in the receiving of a location base station, thus, the positioning accuracy is greatly reduced.

With the improvement of the maturity of various digital technologies, UWB, as the preferred positioning technology of high precision positioning system, has the advantage of 10cm accuracy through wireless carrier communication in indoor positioning, gradually develop the potential in application scenarios such as positioning and pointing. With its high precision and secure precision ranging capabilities, UWB can be used to determine the maximum 200m distance between peer devices with centimeter-level accuracy.

How to realize high precision positioning by UWB positioning technology

With its high precision and secure precision ranging capabilities, UWB can be used to determine the maximum 200m distance between peer devices with centimeter-level accuracy. UWB is especially suited for applications that require location, such as secure hands-free access control (car keys, cell phones or badges) , real-time indoor location (RTLS) , or for smart homes, smart factories, transportation, or healthcare.

UWB uses time of flight (TOF) to determine the distance between peers, and TOF to measure the propagation time of RF signals between transmitter and receiver. This time measurement is multiplied by the speed of light to determine the distance with high accuracy, uWB offers greater accuracy and security than other techniques that rely on measuring signal strength to estimate distance.

Why Choose UWB Technology for High Accuracy Positioning System?

1. Safety:

Technologies such as Bluetooth or RFID rely on signal strength measurements to assess distance and are vulnerable to other signals. Instead, UWB relies on nanosecond non-sinusoidal narrow pulses to transmit data, and its range measurement is not based on signal strength, but time. Thus, it is more secure in signal reception and can provide additional security such as encryption.

2. Accuracy:

UWB can achieve positioning accuracy of more than 10 cm, and unlike other transmission technologies that also provide positioning, UWB uses a very wide channel width from 500 MHz to more than 1 GHz, and very short pulses (< 2ns) .

Bluetooth, by contrast, uses a 1 MHz channel width and Wi-Fi up to 160 MHz, with a large channel width and short pulses that insulate the technology from narrow-band signal multipath effects.

Thus, even in environments with reflective or refracting interference sources, it can provide high accuracy and make it a great technology for deployment in residential or industrial environments.
