5G and Mobile Test Automation: What is the Impact?

Based upon the technological changes and significant advancements in speed, capacity, and capabilities, mobile networks. The first generation, named 1G, started around the early 1980s; currently, we are at 5G, the fifth Generation. With 5G, the mobile network speed has increased to 10 Gbps. Also, 5G provides many features like ultra-low latency, massive connectivity for IoT (Internet of Things), and enhanced mobile broadband.

In this article, we discuss how 5G has impacted mobile test automation.

Evolution of 5G

The fifth generation of mobile networks delivers ultra-high-speed internet, extremely low latency, and the ability to connect a vast number of devices simultaneously. Compared to the previous generation networks, the 5G network operates on a broader range of frequencies, including millimeter waves, contributing to enhanced performance characteristics.

Let’s go through a few crucial features of 5G.

  • Enhanced Mobile Broadband (eMBB): The maximum download speed provided by 4G networks was 300 Mbps, whereas 5G offers a download speed of 10 Gigabits per second (Gbps), a huge transition. This means we can do instant data transfers and applications that manage large amounts of data work effortlessly. Also, mobile apps with high-resolution videos, complex 3D graphics, and real-time data processing will benefit significantly.
  • Ultra-Reliable Low-Latency Communications (URLLC): Latency refers to the time taken for the data to travel from sender to receiver. When 5G offers less latency, it means data is received from sender to receiver within milliseconds or less. For 4G, the latency was about ten milliseconds. This reduction in lag is crucial for applications that require real-time responsiveness, like cloud gaming, remote surgery, and other collaborative editing tools.
  • Massive Machine-Type Communications (mMTC): With the broader range of frequencies, 5G can support more number of connected devices when compared to 4G. This helps to increase the usage of IoT devices, which allow a large number of sensors and gadgets to communicate simultaneously. Mobile applications that are used to control these IoT devices need to be tested thoroughly to ensure that they can manage these increased loads and be stable.
