We can see that the wireless industry are moving forward with the introduction of 5G. Before we see a 5G roll-out to the mass market there is still some work remaining to be done. But our customers are already now starting to run initial trials and try early deployments. We have listened to them and we have a good understanding of what they need. We have answered to their initial testing requirements and we now have the first MIMO OTA 5G measurement solution available
Here at Bluetest, the reverberation chamber is more than a test box. It is a core set of technologies for which we continually find new applications - almost as fast as our users do!
As a statistical sampling platform, our systems inherently distill core insights from complex scenarios. Often, the more complex the interactions, the more useful engineers find the reverberation chamber. Today, wireless devices, their components and networks come together to provide one of the most complex, yet productive systems around. Reverberation Chambers, when paired with Bluetest innovations, regularly cut through the chaos and allow engineers and technicians to evaluate and solve problems quickly. Check-out just a few of the many applications we deliver on below:
LTE-Advanced and Carrier Aggregation
Bluetest solutions provide insight into the data handling capacity of LTE devices and verify that the 4G capabilities such as MIMO and carrier aggregation are delivering on the promise of high performance wireless.
Preparing for 5G
As wireless systems and devices leap towards the next generation of connectivity, Bluetest provides the test environment to test your next generation innovations.
Bluetest systems can accomodate the unique form-factors and system complexity of todays automotive designers as wireless systems become inseparable from vehicle functionality.
Reverberation chambers inherently simplify OTA tests, but Bluetest systems go further and provide flexible, automated solutions that are accessible to everyone on the innovation team.
The power of ubiquitous data networks is rapidly expanding the number and type of devices demanded. Bluetest chambers help to quickly certify devices of all shapes and sizes.
Testing Wearable Devices
In reverberation chambers, movement is a natural part of the process, not a repeatability challenge. This means Bluetest systems provide a natural test environment for testing complex physical interactions.
Passive and Active Antennas
Bluetest reverberation chambers provide fast and intuitive insights into antenna performance. Perfect for designers faced with challenging peformance requirement, complex element solutions and unique physical constraints.
Internet of Things (IoT) and Machine to Machine or M2M communication is an application area quickly growing in importance both in the professional and domestic market. The professional segment includes different kinds of wireless metering, wireless diagnostics and supervision, while the domestic market focuses on smart home appliances. Together they include devices with a wide range
As the variety of wireless devices and wireless connections in a car increases, there is a corresponding increase in the need for testing to ensure good functionality and performance. Automotive engineers are finding that Bluetest reverberation test systems are often the most convenient solution for understanding the effects of wireless devices in, around and embedded in vehicles.
Although WLAN has been around for many years it has during the last couple of years grown rapidly in importance, driven mainly by the introduction of WLAN into mobile devices and operators offloading data from their cellular networks. Another force contributing to the strong growth is the trend to have “everything” connected, for example home appliances as well as different types of metering and sensors.
We are in the forefront of providing measurement solutions for the newest communication systems. We don’t let you wait for measurement solutions supporting technologies that is introduced now. A proof of that is our introduction of MIMO functionality already in 2009 and support for 2 component carrier aggregation (2CC) in 2013.
It is common nowadays to add a cover to your mobile phone, both for protection and esthetical reasons. They are available in many different stores including the mobile operator branded stores. The material and form varies considerably from one cover to another. You can get everything from plastic and rubber covers to silicon or metal. Of course the different materials have pros and cons. Some are more protective, even against the delivery of data. The question that follows is; how does a cover affect the performance of the antenna?
For the last couple of decades, reverberation technology was soley used as a tool for engineers specializing in electromagnetic compliance (EMC) testing. Bluetest innovations have transformed this technology into a powerful solution tuned to the needs of current wireless developers. They are the next generation of over-the-air (OTA) test systems that bridge the testing gap between conducted and drive test methods.
A reverberation chamber is ideally suited for testing antennas for multi-antenna technologies such as diversity and MIMO. Bluetest Flow for diversity and MIMO measurements are well-proven and will give you instant feedback of the performance of the antenna array after the measurement is finished - no waiting time needed! In combination with the extreme measurement speed, the user will have the antenna performance in a single minute only.
Antenna efficiency goes under the category of Bluetest passive measurements in the reverberation chamber. An important parameter for all different types of antennas is radiation efficiency and is a basic parameter for all antenna designs. In fact, it is the dominating factor for antenna performance in multipath environments.
Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS) goes under the category of Bluetest's active measurements. Active measurements means that the transmitter/receiver in the DUT is active and powered up. Active measurements will give you a complete overview of how the whole system in your device is performing. These are parameters directly related to the antenna radiation efficiency,
