Technology allows us to stay connected, provides unhindered access to information, makes our lives easier, and opens up incredible opportunities. Communication standards are rapidly moving to new levels of technical solutions, leading to new opportunities far beyond traditional communication.
There are several levels of communication. The standards are 3G, 4G, and 5G, where the letter “G” stands for Generation and forms their chronology. The difference between 3G, 4G, and 5G lies primarily in the data transfer rate.
It all started with the 1G standard, from which the technology has gradually improved. Today, 5G is introduced globally, with a complete transition planned to take place by 2030-2035. In the meantime, scientists have already developed technical documentation with the alleged capabilities and features of the 6G standard, but the novel concept has not yet been officially announced.
The relevance and importance of all the Gs lie in the fact that the development of communication standards is one of the defining milestones of global technological progress. The capabilities of all automated systems depend on the speed and reliability of data exchange.
With that being said, let’s discover each existing standard, find out the main 3G/4G/5G differences, and look over the main cases of employing each.
What is 3G?
3G networks is the longest-living communication standard that has become synonymous with “mobile Internet” for many. It is the third generation of mobile telecommunications technology, which runs on signals being passed between phone towers. Your mobile phone sends and receives information from the nearest tower via a network managed by your mobile phone provider (Three, O2, Vodafone, or EE in the UK). That’s how you can make and receive calls and access mobile internet.
3G is an evolution of the previous 2G technology. Back in the day, 3G brought the unprecedented top speed of data transmission, access to multimedia services, and seamless roaming. Third-generation mobile communications are based on packet data transmission. 3G also offered a more efficient use of channel resources and an increase in the operating frequency range (400 MHz — 3 GHz).
This enabled providers to offer services to a larger number of subscribers with better quality. The main standing-out features and characteristics of the standard included:
- speed of up to 2 Mbps;
- increased bandwidth and data transfer rates;
- an ability to send/receive large email messages;
- large capacities and broadband capabilities.
However, as well-proven as it is, the glory days of 3G are in the recent past, and the standard is being slowly but steadily stamped out by the fourth and fifth generations.
What is 4G and the Difference Compared to 3G
4G has become the next-generation standard for mobile networks. These IP-based networks were developed in 2000 and have been introduced in many countries since 2010. The key difference between 3G and 4G is that the new technology is about three times faster than 3G and can support many more users. That is why all major UK telecom operators immediately adopted 4G.
What is the difference between 3G and 4G? Mostly, the speed. But we may also point out the following:
- 3G network does not allow watching movies and videos in high quality, which is easy to do with 4G;
- 3G has data rate limits, while the 4G network provides high-speed web connection to any user;
- many online services simply fail to run correctly within 3G, which is not an issue for the fourth generation.
The transition from a 3G network to 4G heralded higher, more reliable, and optimized data transfers. 4G allowed people to stream movies and songs, make video calls, and play online computer games without experiencing lag. It also enabled users to use their mobile phones as an efficient personal hotspot for their laptops or other devices while out and about.
What is 5G and the Difference Compared to 4G
5G is the fifth-generation technology standard for mobile networks set to deliver even higher multi-Gbps peak data speeds, ultra-low latency, more reliability, and higher bandwidth than 4G. More than that, 5G is an improved 4G standard, implying the same combination of technologies and full “backward compatibility” with former 4G infrastructures. In the UK, 5G coverage has been available in major cities since 2019.
One of the main differences between 4G and 5G is the transmission speed: 5G is about 20 times faster than 4G. Then, there is also the ability to serve many more client devices. The new standard allows reaching up to a million customers in an area of 1 km².
5G operates in a different radio frequency band than 4G, which allows for revolutionary improvements in network performance. While 4G operates at frequencies lower than 6 GHz, the 5G standard uses frequencies in the 30 – 300 GHz range.
To put it in perspective, the 5G standard is necessary for the large-scale functioning of the Internet of Things (IoT). It connects various devices to the web (from self-driving cars to "smart" electric kettles), introduces remote control of vehicles, and streamlines operations in medicine, industry, science, technology, and all other areas without exception.
What is the Difference Between 3G and 5G?
As opposed to the third generation, 5G is designed to provide much higher data rates and lower latency. Whereas 3G offers data speeds ranging from around 200 Kbps to 2 Mbps, 5G boasts 1 Gbps to 10 Gbps speeds and beyond.
In terms of latency, 3G primarily operates in frequency bands below 3 GHz, which grants better coverage but limited data capacity. 5G uses a wider range of frequency bands, including both sub-6 GHz frequencies for broader coverage and mmWave (millimetre wave) frequencies above 24 GHz for ultra-high data rates. The use of mmWave allows for massive data transmission but requires more cell sites due to its shorter range.
The biggest difference between 3G and 5G, however, is that providers are gradually abandoning 3G, while 5G is the latest focus for adoption.
