In an ideal world, service verification for voice, data, and mobile broadband usage would probably look a lot different than it does right now. Test cycles would be perfectly matched to the timelines for updates, testers would be able to complete tests for the entire range of use cases with time to spare, and any bugs uncovered could be addressed before new updates were rolled out. Unfortunately, that’s not really the world we live in. Instead, we’re stuck with update cycles that are often too short for thorough use case testing, and service verification begins to feel like an unwanted albatross around the neck of any given telco operator.

Okay, let’s say you're one of the major telco operators in your geographic area, and in order to increase your competitiveness you’re hoping to be the first one to roll out a 5G network for mobile voice and data. You’ve spent months laying the groundwork and taking pains to get your equipment and protocols in line with the new standards, and you’ve done your market research to determine the level of demand among local users (including adoption of 5G-enabled devices, etc.). It’s “all steam ahead,” and the only question is how quickly you’ll be able to get your product to market.

Network demands have grown increasingly complex in recent years. For example, people's reliance on smartphones for everything from navigation to mobile banking means that networks must be more robust and secure than ever. Meanwhile, the proliferation of IoT-enabled devices has introduced new protocols and device configurations.

5 Tips for Automating Your Network Migration Tests

Let’s say you’re a telco service provider: after careful deliberation, you decide to migrate your network in order to improve bandwidth for your growing customer base. After some time, the hard part appears to be over—you developed a plan that involved key stakeholders, you sketched out the scope of the migration, and you updated all of your switches and other equipment as needed. Now, it’s just a matter of verifying that you’re still providing all of the services you think you’re providing.

5G Is Coming: How Will Your Device Testing Keep Pace?

In June of last year, The 3rd Generation Partnership Project set the official standards for standalone 5G, effectively paving the way for the era of true 5G functionality. It might be a little bit of an exaggeration to say that we’re now experiencing a race to create usable 5G networks and devices among the wireless carriers and device manufacturers of the world (Apple, for instance, has been forthright about its decision to wait until 2020 to roll out its first 5G-enabled smartphone), but the floodgates are certainly beginning to open—and carriers like Verizon and AT&T are already performing a limited rollout of 5G home and mobile networks. In Europe, a leading operator in the 5G space has already announced its support for the OPPO Reno 5G.

Can Testing Automation Improve Network Quality?

According to a recent McKinsey study, network quality concerns comprise some of the most important factors impacting a given customer’s choice of mobile carrier. While pricing is still the most important one on average, survey respondents were also quick to list national and local coverage, network speed, and quality of 4G as critical deciding factors in carrier selection. In spite of the growing importance of network quality, however, McKinsey also found that the average quality of service for voice has decreased across Europe in recent years.

6 Reasons Network Testing Is More Complex Than Ever

A few years ago, a tester working on a typical telco project could run through about 10 use cases per day. Now, that number is closer to 8 use cases per day. This trend might be worrying from the outside, but if you’re a test engineer within the world of telecommunications it really shouldn’t be shocking. After all, as the complexity of global networks skyrockets, it stands to reason that verifying service for any particular node or function would become incrementally more complex as a result. The question is: what can network operators do about it? How can you maintain standards and achieve a positive testing ROI in these increasingly difficult environments?

Is Manual Device Testing Hurting Customer Experience?

In 2012, an OpenSignal study found that there were about 4,000 different Android device models on the market. Within a couple of years, that number had risen to 12,000, and it’s likely only gone up since then. As a device tester, you already know that there’s considerable diversity among your customers, and that their needs are going to vary on a case-by-case basis—but who knew there was so much diversity just in the devices themselves?
