what’s the difference between 4G and 5G?
In: Technology
The main focus of 4G was to provide high speed internet connection for a consumer. As the consumer telecommunications market saturates, they wanted to design a system that would serve wider range of applications – such as self-driving cars, Internet-of-Things and others. These don’t necessarily need high speeds, bet they require high reliability or energy efficiency. You might ask then – why couldn’t 4G do all that? The answer is that 4G connections have long message round-trip-time (latency) and it’s radio requires a lot of power. 5G tries to improve on that. If all goes well, factories or warehouses that need wireless communications for their devices or robots can just rent communications system from the mobile operator instead of designing it themselves (which is an expensive endeavor). Of course, 5G will also improve the speed for us consumers, but that no longer is the only focus.
