Troubleshooting 5G: How to test all 5G chipset manufacturers

In early 5G rollouts, it’s important to understand how all the major smartphones work, not just the one recommended by your infrastructure vendor.

To do this, we’ve learned that it's best to test with all the chipsets used by the most popular smartphones to pinpoint and solve the root cause of problems early.

The three major 5G chipset manufacturers are:

  • Qualcomm (Snapdragon 865)
  • Samsung (Exynos 990)
  • Huawei (Kirin 990)

Sometimes critical issues only emerge on certain smartphones in rare circumstances. But if the problem isn’t detected early it can cause huge problems down the line – 5G testing challenges.

Testing across a broader set of 5G chipset manufacturers will accelerate your overall troubleshooting process and ensure that you have the right data available to address issues at the root cause of the problem – infrastructure, smartphone vendor, or chipset vendor.

Full chipset logging is critical for troubleshooting with 5G chipset manufacturers

One important recommendation we stress is full chipset logging for each 5G chipset. This sounds unnecessarily complicated, but has proven to be the key factor in identifying the root cause of complex problems for our existing 5G customers.

At the early stages of any technology rollout, changes are often made on a daily basis… and many players are involved. Hence, both infrastructure vendors, smartphone suppliers and chipset vendors, have been keen to know the full details whenever a problem is detected. Full chipset logging provides that capability, so we highly recommend that this is always done in the early stages of a rollout.

All three chipsets will provide performance improvements over earlier versions, so we expect that an increase in maximum data throughput speeds will be seen, but some offer the possibility of completely new functionality such as support for 5G SA and Dynamic Spectrum Sharing. Others allow equipment vendors to showcase new functionality. Infovista is proud to be involved in helping to verify that the future happens now.

Infovista supports all three major 5G chipset manufacturers

With the release of TEMS Investigation 22.0 we are proud to support all three of the latest major 5G chipset manufacturers in the TEMS Portfolio. The Qualcomm Snapdragon 865 is likely to be the most widely used, but in many countries, the Samsung Exynos 990 and the Huawei Kirin 990 will be used by the most popular smartphones.

All three chipsets are clearly extremely capable, but on paper, will have slightly different capabilities. This means that, especially early in the 5G network rollout, it will be extremely important to understand exactly how each smartphone and chipset really works on the network under test. We are seeing that more and more mobile operators are requesting support for new smartphones, based on one of these different chipsets.

We have already helped verify the performance of some of the most important new smartphones, including:

  • Samsung Galaxy S20+
  • LG V60 ThinQ 5G
  • Sony Xperia 1 II (mark2) 5G
  • OnePlus 8 5G
  • Xiaomi Mi 10 Pro 5G

Take a closer look at the newest 5G devices we support.

Leverage new machine learning methods to solve voice quality challenges on devices

In addition to out and out performance, all of the smartphones will of course be designed for making calls. Many will include proprietary features that filter noise and improve voice quality.

These are fantastic features for your users, but they present significant challenges if you are trying to pinpoint the underlying network issues. In many cases, it can mean that introducing a new phone to measure voice quality will give a better score, and imply an improvement in network quality that hasn’t occurred.

In order to avoid the influence of the smartphone design on the measurement of long-term voice quality, we have introduced a new revolutionary method of determining the underlying network Voice Quality, called sQLEAR. This uses machine learning to determine the voice quality provided by the network. After the move to 5G, all voice calls will be made over the EVS codec, so it is highly recommended to verify that it’s use in VoLTE works perfectly today. sQLEAR is designed for testing this while drive testing.

As we’ve said before, 5G is different from all its “G” predecessors and you need to make sure your rollout plan takes all of these new 5G challenges into account.
