The wireless industry is moving rapidly forward with the introduction of 5G. Bluetest customers are now starting to run device testing, base station testing and 5G trials using the latest Bluetest test systems. We have listened to their input and have a good understanding of their needs in order to succeed. Our 5G line-up with RTS65 and its 5G extension package for device testing as well as RTS85HP for base station testing is fully prepped to help our customers succeed with the launch of 5G.
5G and the reverberation chamber
Bluetest 5G extension packages are providing comprehensive end-user capabilities that cover dual connectivity, high frequency, multi-carrier and multi-stream MIMO measurements. Combined with measurement software for the leading 5G communication testers, we have created a complete offering, ready and released to meet the demands of your 5G test requirements.
The 5G high frequency extension package increases frequency range and enables measurements up to 40/43GHz*, without excessive chamber loss or challenges with hardware limitations. For example, efficiency measurements and data throughput measurements are executed just as quickly and easily as before, all the way up to 40/43GHz*.
More parallel carriers and MIMO-streams
16 uncorrelated sub-6GHz measurement antennas unified with internal combining options of the communication testers or external combiners, provide full flexibility for setting up virtually any number of carriers and parallel MIMO streams - while keeping path loss to a minimum. These streams can be supported in parallel with the two mmWave streams, allowing, for example, aggregated data throughput measurements on 5CC LTE + 4CC 5G NR at 28GHz as well as a wide variety of other configurations and combinations. Bluetest is fully utilizing the unique capabilities of the reverberation chamber to support multiple streams in multiple frequency bands.
*43GHz versions can be provided upon request.
Expanding 5G applications
The combination of additional MIMO streams and the possibility to use frequencies all the way up to 40GHz and above becomes more important with the introduction of 5G and dual connectivity. The Non-Standalone mode 5G NR relies on a sub-6GHz LTE carrier for control and signaling while using the 5G carrier to accomplish higher data rates. Even with Standalone 5G it is likely we will see the a sub-6GHz 5G carrier handling the control plane while mmWave is used for additional data capacity combining both a reliable connection and very high data rates.

5G introduces a new network architecture to support increased capacity and lower latency. 5G technology should enable a more flexible, reliable, and secure network for everything that will be connected. As we see many diverse use cases, the network needs to respond to combinations of requirements from different application areas. 5G targets improved data rates, much higher data volumes, improved battery life and increased efficiency in a network of many more connected devices. These significant improvements, in nearly every aspect of wireless connectivity, promise a 5G future full of exciting developments.
5G use cases
The target for 5G is to support a wide range of use cases, each with its own set of system requirements and testing needs. A common denominator is the “Internet of Everything" where more or less everything gets connected. The many use cases imply very different kinds of devices, which can be broadly categorized in three main areas:
Enhanced mobile broadband
Delivering high speed data to many devices at the same time is very much the focus of current 5G introductions. How can device designers and network operators deliver orders of magnitude higher throughput under challenging wireless conditions? As 5G solutions emerge with even higher data rate requirements, we are positioned to explore the effects of these solutions under both simple and challenging wireless propagation environments.
Mission critical ultra reliable
This is the area where we find vehicle to vehicle communication but also other types of devices that require low latency and ultra-reliable/ultra-secure connections possibly combined with high mobility and speed.
Internet of Things (IoT) type communication where the network needs to handle massive amounts of devices. Each device may not generate a lot of data but will require easy network access with minimum signaling and battery consumption.
