Measurements and setup

RanLOS large test system is optimized for full vehicle measurements. The smaller test system is ideal for smaller base stations or devices. 

With RanLOS solutions you can do both passive and active measurements. Passive measurements such as radiation pattern and gain measurements of antennas. Active measurements such as data throughput up to 2×2 MIMO.


The measurement system consists of a cylindrical reflector with a linear feed array. The feed array consists of dual-polarized antennas. The feed array illuminates the reflector which will create a plane wave in the test zone. This means that we can perform measurements in far-field conditions, even though we are at a short distance from the reflector.

By connecting an instrument, either a network analyzer or communication tester, you can perform either passive or active measurements. The device under test is placed on a turntable in front of the reflector antenna. The instrument and turntable are both easily controlled through
the RanLOS software.


You can perform a measurement in 5 easy steps. Read more and download details about our software on our software and service page here.

Our system is preferably used in an anechoic or semi-anechoic chamber. This will give a controlled environment with no interferences. However, the system can also be used in simpler setups, such as an outdoor tent.

Yes, you can measure radiation pattern. You can measure 2D radiation pattern of large devices, such as cars. We are currently developing a tilt system for being used together with the Sub-6 GHz system, this will make it possible to measure semi-3D radiation patterns.

With the mmWave system you will be able to measure a full 3D radiation pattern.

About measurements and setup​

With RanLOS solution you can currently measure antennas in the frequency range 0.7 GHz to 6 GHz as well as 27-29 GHz. 

We are currently developing 6-12 GHz.

We do not have a solution for 55 GHz and 77 GHz yet. However, we are looking into this. Feel free to contact us to talk and discuss other frequencies than the ones we currently provide (0.7 – 6 GHz and 27-29 GHz).

 

Yes, we can measure up to 2×2 MIMO data throughput.

Yes, it has been validated . 


 

RanLOS has participated in the government founded project Innovation and Simluation of Wireless Technologies toghether with RISE, Volvo Cars, Volvo AB and Lund University. 

RanLOS Sub-6 GHz was validated during this project. For RanLOS the three-and-a-half-year long project has been a great success, and has resulted in that we now can offer commercial wireless communication tests for full-scale vehicles. The project has also resulted in two journal papers and three conference papers, covering the RanLOS measurement system.

Yes, we provide a turnkey solutions.

By connecting an instrument, either a network analyzer or communication tester, you can perform either passive or active measurements. The device under test is placed on a turntable in front of the reflector antenna. The instrument and turntable are both easily controlled through the RanLOS software.

Additions and compatibility

The RanLOS software is module-based and supports a range of different instruments and positioners. See full list in our product sheet which you can find here: RanLOS Software and Services

No, but we have partners that can provide the chambers. Contact us for more details.

Yes, we sell turntables and positioners for smaller devices. For larger devices, such as vehicles, our software supports already existing turntables and positioners.

Yes, we provide calibration antennas.

Commonly used words...

The measurement system consists of a cylindrical reflector with a linear feed array. The feed array consists of dual-polarized bowtie antennas. The feed array illuminates the reflector which will create a plane wave in the test zone. This means that we have far-field properties in the test zone, which means that we can perform measurements in far-field conditions, even though we are at a short distance from the reflector.

We aim to create a better connected society. To do so we need easy-to-use and flexible solutions for testing wireless performance over-the-air (OTA). It includes all relevant standards today and tomorrow; such as 3G, 4G, 5G, and WiFi. Work with us and start measuring easier, faster and smarter.
