RanLOS AB publicerar bokslutskommuniké för 2023

Hög säljaktivitet på global skala
Flertalet viktiga milstolpar har uppnåtts under 2023. Det har varit stort fokus på sälj, leverans och att bygga pipeline tillsammans med de globala återförsäljarna:

  • En delleverans har gjorts till den europeiska premiumbiltillverkaren som RanLOS fick en order av i mitten på 2023. Två ytterligare delleveranser kommer att genomföras och faktureras under 2024.
  • Pipelineutveckling: Vissa kunder har redan valt RanLOS som teknisk lösning och ansöker om intern budget, det uppskattade värdet för dessa affärer räknas till cirka 7 MSEK. Framgångsrika demonstrationer bidrar ytterligare till pipelineutvecklingen, dessa affärer värderas till cirka 10 MSEK. Utöver detta har tekniska möten hållits med kunder som utvärderar RanLOS lösning. Totalt värde för pipelinen under 2023 uppskattas till 70 MSEK.
  • En annan viktig milstolpe har varit att få ökad synlighet på marknaden. RanLOS marknadsföringssatsningar resulterade till exempel i en omslagsartikel i Microwave Journal, en av de främsta globala tidningarna i branschen. Det blev även stort intresse i samband med RanLOS partnerskap med Anritsu för 5G testning av fordon. Anritsu är en av världens största leverantörer av mätinstrument. Artikeln spreds globalt och översattes till fem olika språk.

Efter periodens slut säkrade RanLOS finansiering från huvudägare, Almi, samt bank på 4 MSEK. Lånen kommer endast tas vid behov, i det fall förväntad försäljning uteblir.


VD-kommentar
Under 2023 nådde RanLOS nya höjder. En av de mest noterbara prestationerna har varit uppbyggandet av vår pipeline på ca 70 MSEK med några av världens främsta biltillverkare, underleverantörer och testlabb.

Vidare har vi haft flera framgångsrika demonstrationer som tydligt visar tillförlitligheten och enkelheten hos vårt system. Dessa demonstrationer har inte bara imponerat på kunder utan även väckt nyfikenhet och intresse hos potentiella samarbetspartners. En följd av detta är bland annat det partnerskap vi har fått med mätinstrumentbolaget Anritsu.

Marknadspotentialen för OTA-testning är stor och växer stadigt. För närvarande är det endast ett fåtal fordonstillverkare som har investerat i egen mätutrustning för att mäta connectivity. Men med en ökande efterfrågan förväntas detta bli standard inom några år. Genom att integrera vårt system med Anritsus instrument för 5G-mätningar, har vi skapat en nyckelfärdig lösning som alla kunder har råd med, den första med potential att bli standard på marknaden.

Allt detta ger oss inte bara trovärdighet och förtroende, utan också en stark grund för fortsatt tillväxt och framgång. Vår vision och dedikation driver oss att fortsätta att vara pionjärer inom vår bransch. Dessa spännande framsteg för RanLOS pekar på ett lovande 2024!

Maximizing communication quality: Unlocking the optimal antenna placement for cars

Maximizing communication quality: Unlocking the optimal antenna placement for cars

To optimize the connectivity of the car, the position of the antennas is of high importance. In this application note, we explore how car manufacturers can maximize communication quality and unlocking the optimal antenna placement for cars.

antenna placement on modern car

Introduction

To optimize the connectivity of the car, the position of the antennas is of high importance. The car is normally made of metal parts which are acting as a ground plane, therefore the body of the car, i.e., the shape is very much affecting the antenna performance and thereby the connectivity. A relatively common vehicle antenna type is the shark-fin antenna that normally is placed on the roof of the car. It is important that the position of the antenna is optimized to get the best possible performance, both regarding the radiation pattern of the antenna and the connectivity.

The material of the roof has, of course, also a big impact on the overall performance of the system. The roof can be made of, for example, carbon fiber or glass (2). The roof can also be missing as in convertible cars (3), and then an alternative placement of the antenna is needed. This will for sure have an impact on the communication system performance.

An antenna mounted on a glass roof can be an attractive design but is not optimal for the performance of the communication system. The same applies to a car without a roof because the antenna must be placed in an alternative location, for example at the back of the car. In this application note, we will give examples on how different placements of the antenna can result in a reduction of the communication distance.

To be able to position the antenna with best possible communication quality as a result, there is a need of accurate test methods. Tests of a whole car are rather complex processes and expensive test facilities are needed. The needed test equipment is advanced and there is only a few of these test facilities available which make the verification cumbersome.

This is not a practical way forward; the engineers need to perform measurements throughout the whole development process. A misplaced antenna will result in unnecessary bad communication system performance such as, for example, to short communication distance and low communication capacity. RanLOS test setup is designed to be an easy-to-use measurement tool for antenna and throughput measurements. The test equipment is designed to be used in existing chambers or in open areas with weather protection. A long series of verifications and tests have been carried out to verify the quality of RanLOS test technology and these have shown that the technology is very reliable

Different antenna placements

The position of the antenna will give different communication performance. See the pictures below on different car models and antenna placements:

(1) Roof-mounted antenna with a position at the rear of the roof

(2) Modern car with glass or carbon fibre roof

(3) Cabriolet car without roof

Measurements with RanLOS test equipment

RanLOS test equipment is designed to be fitted into simple test sites or existing EMC chambers.

When the car is positioned in front of the RanLOS test setup, two different types of measurements can be performed to characterize the antenna and the quality of the wireless connection to the car…

The benefits of Compact Antenna Test Range (CATR) measurements

Compact Antenna Test Range (CATR) can be used to measure large devices such as cars, at a significantly shorter distance than in traditional far-field test ranges. A source antenna (feed) is used to radiate a spherical wave in the direction of a reflector, that transforms the wave into a plane wave. The device under test (DUT) is illuminated by the plane wave and a far-field measurement can hence be performed. 

When performing frequent testing, accuracy and efficiency are equally important. Traditional far-field test ranges, while effective, often require substantial distances to accurately measure large devices such as vehicles. However, the CATR solution has made it easier, enabling engineers and researchers to conduct measurements at significantly shorter distances without compromising accuracy.

Introducing the RanLOS CATR Solution

The RanLOS test system consists of a cylindrical reflector fed by a linear array of dual-polarized antennas. The reflector is 4.2 meters wide and 3.15 meters tall and can be used to measure a wide range of frequencies. Compared to many other CATR methods, RanLOS has a more flexible solution. The RanLOS test system is easy to install and can be added to already existing EMC chambers. For RanLOS test system the feed is mounted together with the reflector. This means no complicated and time-consuming feed alignment during the installation is needed. Together with the fact that the system is portable on wheels, it is easy to upgrade existing EMC chambers by just rolling in the system. The cylindrically shaped reflector is also scalable in width and can be made in sections and is less expensive to manufacture compared to double-curved reflectors. 

The RanLOS system generates a single plane wave. This plane wave is incident on the equipment under test (EUT) from an incident angle determined by the rotation of the EUT. The polarization of the incident wave can be either linear or elliptical (e.g., circular), depending on how the two ports on the RanLOS system are fed. RanLOS software controls the whole process, from calibration, and controlling the turntable or positioner, to measurement and data plotting and analysis. The user gets full control over the whole test process and can easily perform a measurement in 5 easy steps. The system enables far-field measurements of full vehicles, antennas, communication systems, base stations, and other connected devices at only a few meters distance. The RanLOS software is compatible with all standard Vector Network Analyzers and Communication Testers. The software also supports positioner controllers from major manufacturers and adding new functions and/or instrument drivers is easy. 

Viable for Existing Anechoic EMC Chambers
In a typical far-field anechoic chamber, the electromagnetic field radiated from the transmitting antenna propagates as a spherical wave and reaches the test area, the quiet zone. At this time, even in an anechoic chamber, in addition to direct waves from the transmitting antenna, reflected waves from the floor, ceiling, and side walls simultaneously enter the test zone. This results in a distribution of amplitude and phase fluctuations within the test zone, depending on the strength and phase of the reflected waves. 

Due to these reasons, a better solution is to use a CATR system. The CATR system generates plane waves where the radiated power, in directions other than the front direction, is smaller than the radiation from the transmitting antenna in a normal far-field anechoic chamber. In other words, the propagation is less affected by the floor, ceiling, and side walls. 

In normal spherical wave propagation in a far-field anechoic chamber, there is a free space loss in which the received power decreases with distance because the surface area of the spherical wave increases with distance and the power density decreases. 

In the CATR environment, since it is a plane wave, the power density does not change with respect to the distance in the depth direction within the test zone. That is, the received power at the front and back edges of the test zone is the same. Meaning that the RanLOS CATR solution is a perfect solution for existing anechoic EMC chambers.

Precision in a compact form 
With a reflector height of 3.15 meters, the RanLOS CATR system can be efficiently deployed in smaller chambers or testing environments, saving valuable space and facility investments without compromising measurement accuracy. RanLOS reflector is a very cost-efficient solution to enable far-field measurements. Crafted from precision-engineered carbon fiber, the reflector boasts exceptional durability and precision, ensuring long-lasting performance and minimal maintenance requirements.

Modularity for Frequency Versatility
RanLOS has a modular design using different antenna arrays (feed arrays) to measure desired frequency while using the same reflector. The feed array is easily exchangeable, and it covers an octave bandwidth. To cover the 0.7 to 6 GHz frequency band, the most used frequencies for vehicular communication systems today, three feed arrays are needed. Feed arrays for higher frequencies are on the roadmap, so existing customers can easily upgrade with no need to alter the reflector. This adaptability ensures that RanLOS can effectively accommodate a wide spectrum of frequencies, making it a versatile choice for researchers and engineers working on diverse projects.

Invaluable data for decision-making 
The RanLOS system is used to do Over-the-Air (OTA) measurements and can measure, for example, how antennas radiate in different directions (antenna radiation pattern) or the quality of a communication system. This is important information for the engineer in order to understand how, for example, vehicles receive and transmit data (connectivity/throughput). 

Antenna radiation patterns can be presented in a polar graph (see Figure 1). The graph makes it possible to detect weak directions where the antenna has inferior performance. In the graph in Figure 1 the red trace represents the radiation pattern with the antenna placed at the back of the roof, and the blue when the antenna is moved to the front of the roof. As can be seen in the graph, it is not only the antenna design that is of importance but also the position of the antenna. Therefore, it is important for the design engineer to have a tool to understand the impact of both the antenna design and its position on the vehicle. 

The quality of the wireless connection can be measured with a Radio Communication Tester, simulating wireless communication with a vehicle under test. The test result is presented in a throughput graph (see Figure 2). The graph presents the data throughput as a function of power for one angle. In this graph, it’s possible to identify the receiver threshold which could, e.g., be defined as the received power level when the throughput is 50% of maximum. This is an important quality parameter of the communication system. As can be seen in Figure 2 the step from 100% to 0% throughput is very steep, and therefore the threshold is rather easy to find and a practical parameter to be used in the engineering work. It is also possible to measure and present the throughput for a full 360-degree revolution. 

In Figure 3 it can be seen that the position of the antenna at the back of the roof is better for all directions except towards the forward direction, where the front positioned antenna has better coverage. For example, when the signal is transmitted/received towards the side, at a 100-degree angle, the difference is approximately 15 dB. If the throughput of the communication system is measured and presented at this angle the result is as in the throughput graph in Figure 4. The threshold clearly shows a worse communication quality, at this angle, when the antenna is placed at the front of the roof. 

By using the threshold value together with Friis transmission formula it is possible to compute the maximum communication distance and thus the overall wireless performance of the vehicle. This important information can be obtained by adding, and using, the RanLOS test system in existing EMC chambers. In this way, it is possible to optimize the antenna’s position and compare different antennas and communication systems to improve the overall communication quality. See RanLOS Application Note: “Maximizing communication quality: Unlocking the optimal antenna placement for cars” for more details.

Based on many years of research with a focus on best performance vs price 
RanLOS has its origins in several years of research and development at Chalmers University of Technology and was established by Professor Per-Simon Kildal in 2016. Professor Kildal was one of the foremost antenna experts in the world. 

RanLOS holds patents globally and is recognized as an innovative supplier of CATR test systems for large test objects. RanLOS has been part of many different research projects where the products have been validated together with both customers and academia. 

Below is a comparison between measurements done using the RanLOS test system and an accredited test facility using an NF-FF system. The device under test was an antenna mounted on the roof of a vehicle body. The measurement results show how RanLOS technology is reliable with results in line with advanced test facilities. These measurements, as well as many additional validation measurements, were performed during the Swedish government-funded project “Simulation and Verification of Wireless Technologies” (SIVERT).

Comparison between measurements using the RanLOS OTA test system and an accredited test facility using an NF-FF system. The measurements were of an antenna mounted on the roof of a vehicle.

The measurements show that the results from the RanLOS setup are a reliable solution compared to bigger, more expensive, test facilities. These measurements were done during SIVERT - a FFI-Vinnova project.
Increased future testing needs

There is an ongoing change where wireless systems are becoming more advanced and will require increasingly more tests in order to be verified. This places new demands on the measuring equipment in the lab and a need for efficient and affordable test solutions. 

Only a handful of car manufacturers around the world have invested in their own test systems to measure connectivity on an ongoing basis. It is expensive, time-consuming, and difficult to calculate the return on investment with existing solutions. The consequence is that tests are done late in the development process, for example when the car can be driven on public roads or a test track. 

RanLOS equipment is not intended as a certification system but as a tool to be used continuously during the product development process. The system is a complement during the development process and is used to optimize performance and prepare for certification. 

Conclusion

In conclusion, CATR has made testing more versatile by enabling measurements at shorter distances. RanLOS aim is to make testing simple, accessible, and cost-effective. With RanLOS’ affordable solution, testing can be done every day if needed. In this way, customers can detect problems early and save both time and money by shortening their time to market and launching cars that meet the buyers’ high demands. 

RanLOS solution has many advantages:

  • RanLOS CATR system is a perfect solution for existing EMC chambers since the characteristics of the plane wave results in that the propagation is less affected by floor, ceiling, and side walls and the power density does not change in the depth. 

  • By using existing facilities, costs can be reduced without the need to construct a new anechoic chamber for antenna testing. 

  • RanLOS uses a patented cylindrically shaped reflector that is less expensive to manufacture compared to double-curved reflectors and it is scalable in width and can be made in sections. 

  • Test frequencies can be changed by easily replacing the feed array. (Realignment work is not required as only the antenna array at the reflector focus is replaced.) 

  • By combining the turntable with a chassis dynamometer installed in the vehicle EMC anechoic chamber, it is possible to test the vehicle in driving mode and regeneration mode. 

  • It is possible to combine ADAS functional testing and V2X communication quality evaluation.
