What is 5G?

Since the first mobile phone networks emerged in the 1980s, there have been five generations of technological standards and improvements that drive the capabilities of our mobile devices. Each ‘G’ represents a new generation of mobile network technology. 5G is the most current generation.

The 1G (First Generation) mobile networks were the first analogue cellular systems introduced in the late 1980s. 1G technology was based on analogue transmission for voice calls only. There was no encryption on 1G networks, so calls could easily be intercepted. The sound quality was poor by today’s standards and there were no data services.

2G (Second Generation) brought digital transmission to mobile networks in the early 1990s, replacing the old analogue standard. 2G introduced services like SMS text messaging, MMS, and basic internet data connections. Encryption was also added. 2G technology enabled mobile phones to become smaller and more affordable. Popular 2G phones included the Nokia 8110 and Ericsson GH337.

The main benefits of 2G compared to 1G were improved sound quality and security through digital transmission, as well as text messaging and basic mobile internet access. However, speeds remained slow on 2G networks.

3G (Third Generation) networks arrived in the early 2000s, making web browsing, video calling, GPS and mobile TV possible on phones for the first time. 3G brought substantially faster download and upload speeds compared to 2G. Iconic 3G phones like the Nokia N95 packed new features into slick slider designs.

4G (Fourth Generation) brought another leap in speed and capacity through new protocols like LTE. 4G enables rapid web browsing, video streaming, mobile gaming and file sharing. 4G networks paved the way for today’s media-rich smartphone experiences.

The latest generation is 5G, which rolled out from 2018 and continues expanding globally. 5G brings exponentially faster speeds, lower latency and greater bandwidth compared to 4G/LTE networks. Download speeds on 5G can exceed 1 Gigabit per second. As well as enhancing mobile experiences, 5G will enable new technologies like self-driving cars, remote surgery and smart cities.

While 6G research is underway, widescale 6G deployment is likely still a decade away. For now, 5G represents the pinnacle of mobile network technology, delivering speeds up to 100 times faster than previous generations.

As mobile networks have evolved through each generation, the capabilities of our phones have grown exponentially. With 5G, the future looks brighter than ever for the world of mobile connectivity and technology. Super-fast speeds will open doors that we can only imagine today.
