EXECUTIVE SUMMARY(PDF)

5G networks and services are pretty much with us, but there are still many years of product and service development, network rollout and service creation and delivery effort ahead. For the past few years, and into the future, test and measurement (T&M) will play a central role as 5G networks, devices, services and business models are worked out.

The long-term trends in T&M – virtualization and automation – are emphasized in 5G, as it will be essential to cost-effectively test networks and services that are supporting very many new use cases, all delivered from network slices. In fact, one could conceive of a "testing slice" as a way of simplifying some of the network testing that will be needed in live networks. This would require virtualized test resources, deployed where needed, and spun up or down as required.

The T&M market is enjoying a surge in 5G-related activity even though 4G network testing has not yet disappeared because 4G networks are still evolving; indeed, in some countries, new 4G networks are still being rolled out. The close relationship between 4G and 5G, in particular the use of the 4G core with 5G radio network, and the new technical challenges of testing chipsets, devices, base stations and RAN designed for mmWave spectrum, mean that T&M vendors have had to work hard alongside their NEP and operator partners to develop practical, economic testing methods.

In the short term, there is still a lot of 5G work to do in the lab, on the production line and in the field. It's a good time to be a T&M vendor.

5G Test & Measurement describes the very broad range of T&M activity happening now, and how activity will evolve over the next couple of years as networks start to be rolled out and services are switched on. It describes the specific challenges for testing that are a consequence of 5G – such as the use of higher frequency bands, denser networks and network slicing – and reviews the supply-side of the market. Finally, this report profiles 11 vendors that provide test solutions developed or used in the 5G ecosystem.

COMPANIES COVERED

We are now at the stage where most – but not all – forms of T&M activity are taking place simultaneously, and vendors of T&M equipment are very pleased because a new generation of wireless technology brings with it new testing requirements. The following excerpt summarizes at a high level the testing required as 5G moves from academic and industry research labs into live networks delivering real services. Note that there is considerable overlap in the real world between the broad areas in the chart: components are not tested in isolation and each new release of a 5G feature involves testing in many places in the chart. However, the chart serves to structure discussion of the main issues and challenges of testing for 5G.

5G Test & Measurement is published in PDF format.

Inventiveness & Pragmatism Pays Off in 5G Test & Measurement

Heavy Lifting Analyst Notes

Test & measurement (T&M) vendors are nothing if not creative. Faced with the very rapid arrival of 5G, they have managed to keep pace with the demands of their network operator and equipment vendor customers and deliver testing equipment and test routines that address pretty much the complete T&M lifecycle.

While a few warnings have been raised about the rush to standardization, deployment and service launch, and the dangers this may be storing up for the future, T&M vendors have seen that 5G momentum is unstoppable and have done their level best to help the industry get ready with networks, services and devices that work properly.

What does this mean in practice? One thing is to adapt what's already there so that it can be used for 5G. This approach includes, for instance, developing frequency converters so that current spectrum analyzers can be used with new spectrum bands in, for instance, mmWave at 28 GHz and 39 GHz. An alternative is to repurpose approaches and kit developed some years ago for testing 802.11ad/WiGig devices at 60 GHz, which has the benefit that equipment is more integrated, smaller and simpler than stacked boxes of converters and analyzers.

A second example relates to testing of 3D beam-forming -- a difficult challenge -- which is being carried out in new ways, such as over the new eCPRI interface rather than at the RF layer (which would be the obvious approach), because the time and cost of carrying out a full suite of tests on systems with complex beam-forming algorithms is not economically feasible.

A practical response to the speed of 5G market development is to front-load the testing process. For instance, some T&M vendors are advocating signal and traffic emulation at the base station design stage, rather than the building of physical prototypes that are then tested in the lab. The argument is that network equipment providers (NEPs) can't afford to make mistakes that would involve having to go back a stage in the development process; lost time will result in costly loss of market share.

Another response to 5G challenges is to forge closer links with operators, NEPs, standards bodies and industry bodies representing the major new users of 5G services, such as the automotive and the factory automation sectors. The purpose of such links is to develop realistic test cases, some of which will be new; ultra-low-latency hasn't been possible in previous generations of public cellular technology, yet it is expected to underpin many new applications.

So the T&M industry is being creative and practical, and it is benefiting from this. There is a very large amount of 5G testing going on right now, and some vendors are expecting 15-20% annual growth in 5G testing revenues during the next couple of years.

The Heavy Reading report 5G Test & Measurement describes the very broad range of test & measurement activity happening now, and how that activity will evolve over the next couple of years as networks start to be rolled out and services are switched on. It describes the specific challenges for testing that are a consequence of 5G -- such as the use of higher frequency bands, denser networks and network slicing -- and reviews the supply side of the market. Finally, this report profiles 11 vendors -- including Anritsu, EXFO, Keysight, Spirent and Viavi -- that provide test solutions developed or used in the 5G ecosystem.
