1 . It might seem strange to be making predictions about 2021, but one thing is clear: technology has been affected just as much as every other part of our lives. Another clear thing is that today’s most important technology trends will play a big part in helping us deal with and adapt to the many challenges facing us. From the shift to working from home to new rules about how we meet and interact in public spaces, technology trends will be the driving force in managing the change.

One of the major technology trends that are likely to play out this year is 5G and enhanced connectivity. Each successive advance in mobile connectivity from 3G onwards has unlocked new use cases for the Internet. 3G made web browsing and data-driven services useful on mobile devices, 4G led to the growth of streaming video and music platforms as bandwidths (宽带) increased, and 5G, similarly, will open more doors in terms of what is possible.

5G means that services relying on advanced technologies such as augmented (增强的) reality and virtual reality, as well as cloud-based gaming platforms like Google’s Stadia, become a practical thing, anywhere at any time. They also threaten to make cable and fiber-based (光纤) networks redundant, with their need for us to be tied to a particular location.

In short, 5G and other advanced, high-speed networks make other new technologies available anywhere, any time. A great example is Norwegian fishery operator Salmar that uses a 5G network to automate the care and feeding of its fish. Image recognition algorithms (算法) are used to detect which fish are over or under-feeding, and automatically distribute food and medicine needed to keep them healthy. Initiatives like this will become increasingly important during 2021, where businesses look to increase automation across their workforces.
