How 5G technology can transform our lives

The Mobile World Congress trade show will kick off in Barcelona on Monday. The mobile industry’s biggest annual event will showcase the latest innovations and leading-edge technologies. This year, 5G wireless telecom technology will be a main theme.

5G is supposed to be 100 times faster than 4G, but if it is just about higher speed, would that really have a big impact on daily life?

Since 5G has super low latency, which refers to how long it takes the network to respond to a request, and the technology also allows connection to a large number of devices, these features will bring many new applications.

Hundreds and thousands of different types of devices can be connected in a 5G network, which will realize the potential of Internet of Things technology, paving the way for smart living and smart city.

In the world of Internet of Things, sensors of every gadget can send out alerts. For example, if an elderly is ill or falls over, sensors embedded in a watch or home appliances will keep the family members informed, which will greatly reduce the burden of elderly caring.

Low energy consumption is another selling point of 5G. With this merit, smart devices can practically replace some manual work, like meter reading.

Manufacturing and logistics industries would be able to introduce smart systems, making the monitoring of the production process or tracking of a delivery much easier.

5G is the foundation of smart manufacturing and building a smart city, which could determine the competiveness of a country. Amid this scenario, there is no doubt that 5G will trigger a fresh round of intense competition among equipment suppliers.
