5G: Understanding the Technology that's Changing Connectivity

What is a 5G Network?

5G stands for fifth generation cellular wireless technology. It succeeds 4G LTE networks and enables much faster download speeds, higher connection density, and extremely low latency compared to previous generations.

The official standard for 5G is established by the 3GPP (3rd Generation Partnership Project), which completed the initial 5G specifications in 2018. Unlike 4G, which required the construction of new cell towers, 5G utilizes existing infrastructure and also operates on new radio frequency bands, including mmWave (millimeter wave).

The jump from 4G to 5G is a monumental leap forward - we're talking about peak download speeds of 20 Gbps*, compared to 1 Gbps on 4G. Latency is also reduced to just 1-2 milliseconds versus 20-70 ms on 4G.

*"Gbps" stands for gigabits per second, a unit of measurement for data transfer speeds. It indicates how many billions of bits of data can be transmitted in one second.

So, what does 5G mean in practical terms? It means 5G can handle exponentially more data traffic, paving the way for transformative technologies like self-driving cars, IoT devices, 4K/8K video streaming, AR/VR apps, and more.

How Does 5G Work?

5G uses a variety of wireless spectrum bands and technologies to achieve its ultra-fast speeds and low latency connectivity:

● Sub-6 GHz and mmWave.The radio frequencies used for 5G include sub-6 GHz (under 6 GHz) which provides good coverage area and also mmWave (24-40 GHz) which offers massive bandwidth for superfast speeds.
Advanced Antenna Systems. 5G utilizes MIMO (multiple input, multiple output) antenna technology allowing simultaneous connections through multiple antennas. This increases capacity and density.
Small Cell Networks. 5G will rely extensively on small cell networks - compact base stations that can be installed on light poles, rooftops, etc. This provides localized capacity boosts.
Orthogonal Frequency-Division Multiple Access (OFDMA). This modulation technique allows efficient use of spectrum so multiple users can access the network simultaneously.
Network Slicing. This allows mobile operators to create multiple virtual networks over a common physical infrastructure, tailored for specific applications or clients.
Edge Computing. Processing data closer to the user via small data centers reduces latency. This complements 5G's speed.
 

evolution of networks from 1G to 5G

Who Invented 5G technology?

The development of 5G technology has been driven by extensive collaboration between telecommunication companies, academic institutions, and technology standards organizations around the world. "Who created 5G?" While no single entity can claim to have "invented" 5G, some key contributors include companies like Ericsson, Nokia, Qualcomm, Samsung, Huawei, and ZTE, who have each innovated critical components of 5G networks. International bodies like the 3GPP and ITU have been instrumental in forming 5G standards. At TDK we focus on developing advanced materials and components like ultra-compact DC-DC converters and LTCC AiP devices for 5G small cell base stations. These innovations are integral to enhancing the speeds and connectivity of 5G networks. Our commitment is reflected in initiatives like "Beyond 5G,"  where we aim to expand the potential of 5G technology and contribute to its future advancements.

How Fast is 5G internet?

The launch of 5G represents a major leap forward from previous cellular network technologies. Each generation has successively offered faster speeds and greater capabilities. To understand why 5G is better, let's review the evolution:

● 1G networks in the 1980s were analog systems mainly built for voice calls. There was no encryption, so security was poor. Upload speeds were virtually non-existent.
● 2G networks, introduced in the 90s, were the first to digitize signals for better security and data services like text messages. However, maximum speeds were only up to 64kbps. Downloading a 3 minute song could take over 20 minutes!
● 3G brought mobile internet into the mainstream when it launched in the 2000s. But access speeds were still quite slow by today’s standards, ranging from 384 kbps to 2Mbps. Streaming video or music was not practical.
● 4G LTE, first deployed in 2010, was the first network fast enough for advanced apps, HD video streaming and large file downloads. Peak theoretical speeds reached 100Mbps but were often much lower in reality.

Now with 5G, we are entering a new era. How much faster is 5G than 4G? 5G operates on new radio frequency bands that can transmit much more data. 5G uses shorter transmission bursts to reduce latency to just a few milliseconds. This enables real-time communication for smart devices.

In terms of speed, 5G blows away its predecessors. 5G achieves lightning-fast peak download speeds up to 20 Gbps, compared to 1 Gbps on 4G. To download a full HD movie on 3G would take 26 hours, versus just 3.6 seconds on 5G!

Is 5G better than LTE? Absolutely! The 5G network benefits are extensive, ranging from significantly increased data speeds and reduced latency to enhanced network reliability and capacity, paving the way for transformative changes in sectors like healthcare, manufacturing, and transportation.

Is 5G better than 4G? Without question, yes. 5G brings a 10 to 100X improvement over 4G networks across every metric. From speed to capacity to reliability, 5G marks a radical upgrade.

The capabilities of 5G networking enable a world of seamless connectivity and real-time automation that previous generations could not match. Exploring why 5G is important reveals its critical role in the next wave of technological innovation; it's not just about faster speeds, but also about enabling real-time data processing, connecting billions of devices, and unlocking the potential for smart cities and autonomous technologies. While past generations connected people, 5G will connect the world.

Looking ahead, the groundwork laid by 5G paves the way for future developments like 6G, which will further expand these capabilities and possibilities.
