The difference between 3G, 4G, and 5G comes down to speed, latency, and the real-world tasks each network can handle. 3G introduced mobile internet, 4G made high-definition streaming and video calls standard, and 5G delivers near-instant responsiveness and the capacity to stream 8K video.
What is the difference between 3g 4g and 5g
Here is a direct comparison of the key differences across these three network generations:
| Feature | 3G | 4G | 5G |
|---|---|---|---|
| Introduced | Around 2001 | Around 2009-2010 | Ongoing rollout |
| Typical Download Speed | 1.1 to 20 Mbps | 5 to 100 Mbps | 10 Mbps up to a speed cap of 250 Mbps |
| Typical Upload Speed | 300 kbps to 3 Mbps | 1 to 40 Mbps | Varies by network |
| Latency | 100 to 500+ milliseconds | 50 to 100 milliseconds | Ultra-low (sub-millisecond goal) |
Speed and real-world performance
3G networks were capable of data speeds up to 7 Mbps, though HSPA (an advanced 3G technology) could reach up to 42 Mbps. Typical download speeds on 3G were 1.1 to 20 Mbps, and upload speeds were 300 kbps to 3 Mbps. This was enough for basic mobile internet browsing, email, multimedia messaging (MMS), and basic music and video streaming. In contrast, typical 4G download speeds today range from 5 up to 100 Mbps, depending on factors like location, network congestion, and device capabilities. Upload speeds on 4G typically range from 1 to 40 Mbps. These speeds enable smoother HD video streaming, video conferencing, online gaming, and data-intensive applications. 4G also allowed users to create mobile hotspots. Typical download speeds on 5G are 10 Mbps up to a speed cap of 250 Mbps. This performance can support streaming 8K video and downloading entire episodes in seconds.
Latency and responsiveness
Latency is the time it takes for data to travel between a source and a destination. 3G networks typically have higher latency, ranging from 100 milliseconds to 500 milliseconds or more. This delay can be noticeable during video streaming and online gaming. 4G networks improved this, typically exhibiting latency between 50 to 100 milliseconds, which contributes to a smoother experience for video calls and online multiplayer gaming. 5G networks are expected to achieve ultra-low latency, often referred to as sub-millisecond latency. This near-instantaneous response time is crucial for applications that demand real-time data exchange, such as autonomous vehicles or remote surgery.
Coverage and availability
3G networks had the most extensive coverage globally because they were deployed first. However, 3G networks are being phased out. For example, Verizon phased out its 3G CDMA network completely by December 31, 2022. 4G networks have significantly expanded coverage compared to 3G, offering a more reliable and consistent connection in urban areas and major cities. 5G coverage is currently more limited than 3G and 4G networks, with the rollout initially focusing on urban areas and high-density locations. As the technology continues to develop and more infrastructure is deployed, the coverage is expected to expand rapidly.
How to switch between 3G, 4G, and 5G on your phone
If you need to change from 5G to 4G to save battery or improve signal, follow these steps on an Apple iPhone 13:
- Select Settings.
- Select Mobile Data.
- Select Mobile Data Options.
- Select Voice & Data.
- To enable 3G, select 3G. To enable 4G, select 4G. To enable 5G, select 5G On or 5G Auto.
To enable Smart Data mode to optimize battery life, tap Voice & Data, then choose 5G Auto; the iPhone automatically switches to LTE when 5G speeds don't provide noticeably better performance. To use higher-quality video and FaceTime HD on 5G networks, tap Data Mode, then choose Allow More Data on 5G. To turn off 5G, tap Voice & Data, then choose LTE. If you’re unsure which network your device is currently using, you can tell if my phone is 4g or 5g by checking the status bar, and if it shows LTE despite your 5G plan, here is why your my phone say 4g instead of 5g. iPhones can use internet services while talking on the phone with 5G, LTE, 4G, and 3G service on GSM cellular networks.
What can you do on each network
Its ultra-low latency and massive device connectivity will power revolutionary technologies such as autonomous vehicles, virtual and augmented reality, remote-controlled robotics, and real-time telemedicine.
