Can 5G Replace Wired/Wi-Fi Networks?

5G technology offers impressive download speeds that can exceed 1 Gbps, making it a strong contender for replacing traditional wired and Wi-Fi networks in certain scenarios. However, there are several factors to consider before fully replacing wired or Wi-Fi networks with 5G.

Advantages of 5G

High Speeds: As you mentioned, 5G can deliver high-speed internet, which is beneficial for activities like streaming, gaming, and video conferencing. This makes it a popular choice for users who require quick data transfer and a smooth internet experience.

Mobility: 5G provides connectivity on the go, allowing devices to maintain a fast connection while moving. This is especially useful for individuals and businesses that rely on mobile internet access.

Low Latency: 5G has lower latency compared to previous generations, making it suitable for real-time applications like gaming and remote work. This reduced delay is crucial for many modern applications that require quick responses.

Limitations of 5G

Coverage: 5G coverage is not yet ubiquitous. In many areas, especially rural locations, 5G may not be available or reliable. This inconsistency can hamper the seamless performance users expect from a fully operational internet network.

Signal Interference: 5G signals can be affected by physical obstacles such as buildings and trees. This can lead to inconsistent performance and may require more infrastructure investment to ensure reliable coverage in densely populated areas.

Data Caps: Some mobile data plans may have limitations or caps on data usage. While this is a concern for heavy internet users, it is also a factor that can restrict the full benefits of 5G.

Cost: Depending on the service provider, 5G plans can be more expensive than traditional wired connections, particularly for high data allowances. The higher cost may deter some users from opting for 5G services.

Use Cases

Residential Use: In urban areas where 5G is available, it could potentially replace wired broadband for homes. The convenience and speed offered by 5G make it a compelling option for households that require high-speed internet always on.

Business Applications: For businesses that require mobility and flexibility, 5G could serve as a primary or backup connection. It can provide reliable and fast internet access, especially for remote work and on-the-go operations.

Temporary Installations: 5G could be advantageous for events or locations where establishing wired connections is impractical. The mobile nature of 5G allows for quick and easy setup, making it a flexible solution for temporary needs.

Real-World Experiences

Theorically, you could opt for 5G instead of wired/Wi-Fi networks. In Australia, the Australian government considered having telecommunications companies like Telstra and Optus build a 5G network in main population centers, with the government concentrating on delivering internet to rural areas. However, they opted for fiber to the node (FTTN), Fiber to the curb (FTTC), and in some cases, fiber to the home (FTTH).

With 5G being rolled out by telecommunications companies, people can now compare the benefits of both 5G and the NBN (National Broadband Network). In my experience, the NBN offers most users a satisfactory 50 Mbps service, with some opting for 100 Mbps. The big advantage is the consistency of the speed, whereas minor issues like storms or lightning strikes can disrupt wired connections.

On the other hand, 5G provides significantly faster speeds, up to 1 Gbps. However, this speed is not consistent during peak usage times, causing drops to 25 Mbps or even less. This inconsistency can be a drawback, especially during the most active usage periods. Another issue is that 5G coverage can be patchy, with some areas not covered well by the usual 5G nodes.

For my own experience, I initially used wireless 4G at night, receiving 50 Mbps, but experiencing slow speeds (about 1 Mbps) outside those hours. This suited my needs, as I mostly use the internet after 10 pm. However, for others, this may not be sufficient, prompting them to choose the NBN for its consistent performance, even with the risks of power outages due to lighting strikes.

In conclusion, while 5G has the potential to replace traditional wired and Wi-Fi networks in certain scenarios, it may not be a one-size-fits-all solution. For now, many users may find that a combination of wired Wi-Fi and 5G networks offers the best performance and reliability, especially as 5G infrastructure continues to develop.
