For the best possible results, your test lab needs to make use of the absolute latest in cutting edge technology. Because this is the arena in which you test changes and additions to your network—including new connected devices like the internet of things (IoT)—you need to find a way to replicate existing network conditions as closely as possible. Otherwise, you might test out new service offerings or network adjustments in a lab setting only to find that your service doesn’t work correctly under real life conditions—which could result in costly delays, outages, and potential subscriber churn.
Sometimes, the OS that comes built into an Apple or Android device can seem like it’s actively preventing you from doing what you want. And, to some extent, that’s true—Apple only lets you download the apps that are in the App Store because there are some actions that they want to prevent you from taking. As an end user, this often seems capricious and arbitrary. As a tester, it feels similar: why shouldn’t you be allowed to make the necessary changes and additions to the phone’s functionality to make end-to-end testing easier?
If you’re a telco test engineer, you know that the world of telecommunications is getting more complex by the day. Your service needs to integrate with more devices than ever, and you still have to maintain interworking with any number of legacy systems. This is driving an increase in the number of test cases that require verification, and also a renewed push towards automation across the field. Whether you’re selecting an automation solution or simply trying to keep your testing process as efficient as possible, it’s important to keep tabs on the new challenges and opportunities that are likely to be coming down the pike.
According to a recent GSMA study, the IoT market will be worth $1.1 trillion and include about 25 billion IoT connections by 2025. The majority of those connections will be in the industrial and vertical industry segments (13.8 billion connections) and the smart home market (11.4 billion).
Smart cities. Augmented reality. Net neutrality. The Internet of Things. These are just some of the buzzwords in telecommunications right now. They all indicate a technology-driven shift in the industry, one that has fundamentally changed the successful telecom business model. As telecom companies seek to cut costs and keep customers, they must also take advantage of emerging technologies to power innovation.
In 1877, Alexander Graham Bell demonstrated the possibility of making long distance telephone calls by calling the offices of The Boston Globe. As you can imagine, the press had a field day—and it’s easy to understand why. From the perspective of technological progress, transmitting voice communication over a trunk line successfully was a feat that would have been scarcely imaginable even a few decades before, and the research and experimentation that led to it would have been extremely complex. On the other hand, service verification would have been a breeze. Since the ceiling for voice quality back then was quite low, it was still a simple matter of placing a call and hoping that it went through successfully. If so: service verified.
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?
