5G, 4G and Wi-Fi Network Speed Test Comparison: Which is Faster?

In today's world, where smartphones and high-speed networks are ubiquitous, we switch between different networks every day:

The Wi-Fi at home, the 4G or 5G network when going out, or even the dedicated line at the company. But have you ever thought about which of these networks has the fastest speed? What are the factors that affect the differences in our experiences when browsing the web, watching videos, or playing games?

This article will take you through the real speed test differences between 5G, 4G, and Wi-Fi using actual data and testing analysis, and teach you how to use the ToDetect online network speed testing tool to easily measure the true internet speed of your device.

1. Why is it necessary to carry out internet speed tests?

In advertising promotions, operators often claim "gigabit broadband" and "5G ultra-fast downloads."
However, in actual use, we often find that—waiting to open web pages, video playback lags, and high game latency.

This is the difference between "rated speed" and "actual speed."
The only reliable way to understand your true internet experience is to conduct a speed test.

useToDetect online network speed test toolYou can check in a few seconds:

• Download Speed
• Upload Speed
• Latency (Ping)
• Jitter

This data will directly reflect the quality of your network connection and is a key indicator in determining whether "the internet is fast or not."

II. Measured Results: Which is Faster, 5G, 4G, or Wi-Fi?

Speed test results conducted in various environments show that 5G, 4G, and Wi-Fi each have their own advantages and disadvantages.

• Under normal circumstances, the download speed of 5G networks can reach 150 to 500 Mbps, with upload speeds between 30 and 80 Mbps. The latency is generally between 10 and 30 milliseconds, making it fast and responsive, which is very suitable for high-definition video playback and online gaming.

• The download speed of 4G networks is generally between 20 to 100 Mbps, with upload speeds around 10 to 30 Mbps, and a relatively higher latency of about 40 to 60 milliseconds. Although it is slower than 5G, it has the advantage of wide coverage, making it suitable for regular mobile use.

• Wi-Fi networks (especially gigabit broadband) are the most stable in most cases, with download speeds often ranging from 200 to 800 Mbps, upload speeds reaching 40 to 100 Mbps, and latency as low as 5 to 15 milliseconds, making it very suitable for remote work, online video conferencing, and multi-device connections.

In simple terms, if you prioritize speed and low latency, Wi-Fi and 5G are the best choices; if you focus on signal coverage and versatility, 4G is still a good option.

3. The Best Choices for Different Usage Scenarios

• If you work from home or frequently need to attend online video meetings, Wi-Fi broadband is the preferred choice because it is stable and has low latency.
• If you often go out or travel for business, 5G networks can provide fast downloads and a smooth experience.
• In some areas with weak signals or remote locations, the coverage advantages of 4G networks are more apparent and can still meet daily needs.
• For gamers or streamers, 5G and high-quality Wi-Fi networks can provide lower latency and smoother visuals.

IV. Why do the speed test results vary?

Even when using the same network, the speed test results may vary slightly each time, which is related to multiple factors:

• Network congestion: During peak hours, when many people use the network, the speed will decrease.
• Device performance: An old phone or an old router may limit the speed cap.
• Signal strength: Being too far from the base station or router can cause signal degradation, affecting speed measurement.
• Background programs: Uploading, downloading, automatic updates, etc. will consume bandwidth.

For more accurate results, it is recommended to:

1. Close background downloads, video playback, and other applications;
2. Close to the Wi-Fi router;
3. useToDetect online network speed test toolTake the average of three consecutive measurements.

5. Conclusion: There is no absolute fastest, only the most suitable.

Through comparison, we can draw the conclusion:

• Wi-Fi broadband excels in stability and low latency.
• The 5G network has an advantage in speed.
• The advantage of 4G networks lies in their universality and coverage.

Which type of network to choose depends on your usage needs and scenarios.
