Advantages and Differences: 3G to 4G to 5G
Now that we’ve covered 3G vs 4G vs 5G individually, let’s directly compare metrics across generations:
Speed and Performance
| Peak Download Speeds by Mobile Generation | |
| 3G | 2 Mbps |
| 4G | 100 Mbps |
| 5G | 1 Gbps |
| 6G (goal) | 1 Tbps |
One of the biggest differences is raw speed. Peak 3G speeds clock in around 2Mbps. Speeds for 4G can reach over 100Mbps in ideal conditions. Peak speeds for 5G max out at an astonishing 1 Gbps, with average speeds over 200Mbps. Projected future speeds for 6G go as high as 1 Tbps (terabit per second).
Real-world speeds depend heavily on signal, distance to cell tower, and how many users are sharing bandwidth. But the difference between mobile network generations is significant even under real-world conditions. Download a movie on 3G? Forget about it. Streaming 4K video? No sweat on many 5G connections.
Connectivity and Coverage
The maximum number of devices able to simultaneously connect within a square kilometer continues to increase in each generation as well. 3G allows hundreds of devices, 4G supports about 100,000.
But 5G enables massive IoT deployments of a million-plus devices per square kilometer. The future 6G will support over ten million devices per square kilometer.
| Bandwidth to Support Multiple Devices in 1 Square Km | |
| 3G | < 1000 devices |
| 4G | 100,000 devices |
| 5G | 1 million devices |
| 6G (goal) | 10 million devices |
Rural coverage also keeps improving, extending connectivity with newer equipment and wider spectrum bands.
How many devices?
Latency and Reliability
Network latency refers to lag or delay sending packets between devices. Slow latency ruins real-time experiences like video calls and gaming.
While 3G latency falls between 100-200ms typically, 4G drops to around 30-60ms. The 5G target is blisteringly fast – under 10ms, unnoticeable to humans.
| Latency (Lag) in Mobile Networks | |
| 3G | 100-200 milliseconds |
| 4G | 30-60 milliseconds |
| 5G | < 10 milliseconds |
| 6G (goal) | 1 microsecond |
Reliability of network signals also continues to improve through sophisticated antennas and intelligent traffic-shaping techniques.

Challenges and Limitations
While 5G brings impressive capabilities, the successive rollouts of mobile generations leave us with challenges to solve.
3G
As 3G networks sunset, coverage gaps emerge that leave some rural users behind without internet choices. Those gaps create a digital divide between internet-haves and have-nots. Performance also tends to suffer congestion in denser urban environments.
4G
A key 4G limitation occurs when users get spotty coverage and unreliable performance. Coverage issues are more common while indoors or traveling across challenging terrain. Rural users often still lack access altogether. Congestion also creeps up in crowded environments.
5G
The main 5G challenges center around infrastructure rollout. Tower density remains limited, and home/office penetration is still developing. Flaky in-building reliability will persist until more small access points get deployed everywhere. There’s also work remaining to bridge 5G with Wi-Fi networks smoothly.
Future Trajectory
Predictions and Trends
What does the future look like for mobile networks when we look past 5G deployment?
5G will continue to evolve and improve as companies refine 5G technologies.
Next-generation 6G research has already kicked off too, exploring radical concepts such as terahertz-band communications to allow sci-fi-esque hologram calls.
Here are two key trends expected in the coming years:
Gradual Nationwide 5G Buildout – Coverage will continue to improve as infrastructure rolls out. Rural users will benefit in areas that have been hard to reach with wired internet.

Gains and Costs of Universal Connectivity with 5G
From humble 1G beginnings supporting only voice calls, mobile connectivity has exploded into a technology that supports every aspect of daily life.
5G provides a transformational platform to take speed, responsiveness and versatility to radical new levels.
It’s Not Just Mobile, It’s Home Internet
One of the most important potential uses of 5G is to provide fixed wireless connections for home internet. A fixed wireless antenna that always keeps the same position relative to a tower can often get better signal strength than a mobile cell phone.
Right now, some people try to use mobile hotspots to set up a home Wi-Fi connection. But results aren’t fast, and data limits can get in the way.
Fixed wireless connections maximize the chances that 5G will be able to perform near its ideal fast speeds for internet browsing. For rural customers without wired internet access, this may be an improvement over their current satellite internet options. If fixed wireless connections improve enough, more rural users will be able to work remote jobs.
The Brave New World After 5G
The future promises even more innovations. 5G and 6G will let us connect every process around us to mobile networks.
Buckle up as more “smart” devices and systems surround humans – from cars, to homes, to entire cities. Over the next ten years, AI and superfast mobile technology are likely to change our daily lives in ways we can hardly imagine now.
Will we enjoy the huge changes to our lifestyles? Or will we lose all privacy in the rush of the digital world with 5G and Wi-Fi everywhere? We’ll find out soon enough!
