5G vs. 4G – A Side-by-Side Comparison

As 5G continues its gradual rollout, a question lingers: What exactly are the performance differences between 5G vs. 4G?

We first addressed 5G – its current status and future direction – in a previous blog post a few months back. At the time, there were more questions than answers. We saw concerns about bandwidth and how it could affect battery life. There were doubts about the need for local storage, due to faster 5G speeds. Some worry even came about 5G pushing up the cost of high-end smartphones.

Our answer was simple: 5G is worth the potential risks and, someday, we’ll ask how we ever survived without it. To further put these fears to rest, we detailed five edge design considerations for the 5G era.

Is 5G Just Faster 4G?

Now, let’s be clear: 5G isn’t just beefed up 4G. Yes, faster average and peak speeds are much anticipated with the fifth-generation of cellular networks. But, there are a few other factors worth keeping in mind. Reduced latencies. Higher operating frequencies. More devices supported. Together, these capabilities of 5G vs. 4G could help mobile users break free from existing networks crowded with smartphones, tablets, smart watches, and other IoT-enabled devices.

If 5G does become widely adopted, we could see progress in areas that use real-time communication, such as:

  • Autonomous Vehicles
  • Cloud & Virtual Reality Gaming
  • Immersive Entertainment
  • Instant Movie Streaming
  • Internet of Context
  • Remote Healthcare
  • Smart Cities
  • Smart Factories
  • Smart Grid
  • Smart Homes

To make sense of the two generations of wireless networks, we decided to look into the hard numbers that describe 5G vs. 4G. Here’s what we found.

Peak Speeds – 5G vs. 4G

5g vs 4g

Compared to our current fourth generation, 5G could reach over six times higher throughput. Faster speeds open the door for new possibilities across cellular networks. Data-intensive applications at endpoints – such as downloading multi-gigabyte files and streaming 4K/8K video – could become a reality.

Latency – 5G vs. 4G

Blink your eyes. That’s how fast data might travel from your future 5G-enabled device, over the network to a main server, and back to your device. This extremely low latency – 4-5 times faster than 4G – could enable real-time applications such as self-driving vehicles, advanced robotics, and immersive reality.

Connectivity – 5G vs. 4G

5G could support up to 100 times more devices than 4G – leading to a world more connected than ever. This shift is critical as billions of IoT devices come online and strain existing 4G networks. Think of 5G making possible future cities with smart transportation, efficient energy grids, and remote security.

Energy Efficiency – 5G vs. 4G

One estimate suggests that 5G could use 90% less energy per bit than 4G. Energy consumption has a big impact on battery life for mobile devices. It’s been a thorn in the side for people using smartphones, smart watches, and tablets. By using fast, low-latency 5G networks, more data could be processed in the network instead of on a device. That could mean less energy used and longer battery lives.

Mobile Data Volume – 5G vs. 4G

Imagine high-density areas where thousands of devices communicate across the same network, such as airports or sports arenas. Communication comes to a crawl and data transfer speeds slow down dramatically. With faster speeds and lower latency, 5G could handle 1,000 times the volume of mobile data compared to 4G.
