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 – 5G extension package to RTS65.
5G and the reverberation chamber
We are introducing the 5G extension package in two parts that combined are giving the end user capabilities that covers dual connectivity, high frequency and multiple stream measurements.
The first part of the 5G package is that we are extending the frequency range and enable measurements up to 40GHz*, without too much chamber loss or need to worry about hardware limitations. For example, efficiency measurements are done just as fast and easy as before, all the way up to 40GHz*.
More parallel streams
The second part is that we add even more streams to the RTS65. Up to 16 parallel MIMO streams are now possible to use below 6GHz in our reverberation chamber RTS65. These streams can be supported together with the introduced 2x up to 40GHz* streams. We have taken the maximum advantage of the reverberation chamber’s possibility to support multiple streams in multiple frequency bands.
*43GHz versions can be provided upon request.
Expanding 5G applications
The combination of more MIMO streams and the possibility to use frequencies all the way up to 40GHz becomes more important when 5G and dual connectivity is introduced. It enables having a control plane sub 6GHz on LTE or 5G to get the reliable connection. Then for high data rates and more bandwidth, a data plane on higher frequency bands can be used.
Our newly introduced 5G capabilities gives you functionality for initial trials in the 28GHz band that we have already seen in Korea and USA. At the same time we can support the globally discussed 5G candidate around the 3.5GHz band.
Looking for more information?
5G is expected to introduce 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 planning. 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.
