What Is 5G And How Does It Work? The Reality Behind Faster Networks

Many experts widely believe that 5G represents an enormous leap forward and will somehow bring about an instantaneous change to our planet. In actuality, however, it turns out that 5G is actually a lot more interesting – and much more complex – than what people may believe.

Some of the people using 5G technology are experiencing incredible data transfer rates with great consistency. At the same time, a number of individuals have viewed a full 5G signal on their handset, but have experienced difficulties accessing the internet. This discrepancy is just one of the reasons for the following question…

If 5G is a superior product than 4G, then why doesn’t it appear that way to everyone?

The answer begins with defining what 5G really consists of.

What Is 5G?

5G technology is the next-gen mobile communication network and builds on the four prior generations: 1G, 2G, 3G, and 4G.

The main advantage of 5G over previous generations is the improved speed and mobile internet access. Still, it also has an entirely new range of capabilities that have never existed before.

It introduces changes in how wireless networks transmit data, allocate bandwidth, manage congestion, and support millions of connected devices simultaneously.

Earlier generations focused mainly on improving communication and mobile internet access. 5G expands beyond smartphones and is designed to support connected environments, including vehicles, sensors, infrastructure, healthcare systems, and industrial applications.

How 5G Actually Works

5G mobile technology, like the earlier generations of mobile devices, uses radio frequencies to transmit data from the 5G network to a user’s smartphone.

However, 5G differs from 4G in that it provides greater overall speed and efficiency by utilizing multiple frequency bands, efficient signal management techniques, and a different overall network design.

5G does not limit its signal to a single frequency range, but instead, uses multiple frequency bands, based on the specific requirements for speed, geographic distribution of users, and availability of coverage.

The Three Layers Of 5G

Broad geographic range and stronger signals are provided by low-band 5G. Low-band has many similarities with higher-end 4G in many situations, but it is more stable over larger distances.

The middle band of 5G is generally regarded as the most practical version of this technology. In addition to noticeable increases in speed while still able to deliver a benefit with respect to coverage, many service providers view this as being the most scalable type of 5G rolling out.

High-band (or mmWave) 5G allows for extremely fast data transfer rates and speeds. The trade-off for this tremendous speed, however, is that mmWave does have some constraints on how far a signal can travel and on how well that signal can penetrate obstacles (e.g., walls, buildings, and dense environments). As a result, faster speeds often necessitate more infrastructure.

Why 5G Needs More Towers

One common misunderstanding is that faster wireless networks automatically mean stronger coverage.

In practice, the opposite can happen.

Higher-frequency signals usually cover shorter distances, so telecom operators deploy many additional connection points called small cells.

These small cells may appear on:

• Street infrastructure
• Rooftops
• Urban utility installations
• Dense commercial zones

This is one reason the 5G rollout takes time and investment.

Coverage expansion is often a bigger challenge than increasing speed.

The Technologies That Make 5G Different

5G is More Than Just a Speed.

Many backend Improvements Work as a Team.

One of the improvements is Beamforming. This technology directs & focuses the signal from the network equipment to the active user, rather than using the older methods of broadcasting the signal in all directions (like a light bulb).

Massive MIMO provides additional network efficiency in that it allows the tower to send to more than one device at a time.

N/A: This Version Is Correct

Network slicing creates separate virtual networks for different services and therefore creates different priority levels for each service.

Edge computing decreases the distance from users to where their data is processed and therefore creates lower response times.

Together, these technologies improve responsiveness, scalability, and reliability.

Why Some People Feel 5G Is Worse Than 4G

Here is where expectations and reality frequently conflict. There may be a 5G “connection” icon in your mobile device, but there is no assurance of the fastest service possible. According to some customers, their experience with 4G is generally more stable than what they are experiencing with 5G.

There can be a number of reasons for this. First, when many customers switch over to the new 5G network, the number of users on that particular network often leads to congestion in high traffic areas.

Older infrastructure networks are often relied upon for various reasons when deploying newer technology. 

Older devices can limit your use of certain frequency bands, which can also affect your ability to receive good service. 

Finally, geographic location also affects service levels significantly. 

Someone who’s close to an urban tower and it has the best equipment installed will get much better service than someone who’s inside an available high-density building with no available coverage.

This explains why two users can both say:

“5G is incredible.”

and

“5G never works for me.”

Both experiences can be true.

Standalone vs Non-Standalone 5G

There are several different types of 5G networks in operation today.

Non-Standalone (NSA) 5G is built on top of the existing 4G LTE cellular infrastructure. It relies on new radio technology to provide mobile broadband service.

Standalone (SA) 5G cellular networks have a completely independent and end-to-end architecture with no reliance on any legacy infrastructure.

The difference between these two types of network deployments is significant because many customers expect full performance from 5G networks when connected to partially upgraded legacy systems.

And this is one of the reasons that we see tremendous variability in real-world speed.

Does 5G Matter For Everyday Users?

Modern-day 4G is effective at performing for the majority of daily tasks such as messaging, browsing, streaming, and social networking. 5G is likely to have the largest impact on how networks support activities such as:

Long-term value of 5G will likely be more related to the ability to support services that previous generations of networks were incapable of supporting as efficiently.

The long-term growth of connected technologies depends heavily on broader adoption. Explore the key benefits of the spread of 5G networks and how industries are expected to evolve.

Final Thoughts

5G Will Change How Wireless Works – Not Just Add More Speed.

5G Introduces a Whole New Way to Use Wireless Technology: Includes Greater Spectrum Utilization, Smarter Management of Traffic, Increased Capacity, and Less Latency – But Only If Users Have Good Infrastructure, Well-Designed Deployments, Compatible Devices, and Work Conditions.

This Is Why Some Users Get Immediate Improvements While Other Users May Not Notice Any Changes at All!

The Future of 5G Is Not the Replacement of 4G, but the Development of a Network to Support Next Gen.
