The 5G standard has been finalized, and the shift from 4G to 5G will change just about everything. So with 5G coming, the question on everyone’s mind is, what’s the difference? What advantages does 5G provide for wireless networking that 4G LTE does not? How does 5G change the way applications use cellular networks?

Keep reading to find out the differences between 4G and 5G. 


Speed

Many comparisons between standards will always prompt the question about speed. Yes, 5G is fast. So fast, events will be transmitted in almost real-time. With higher bandwidth, higher capacity, and more wireless frequencies to take advantage of, the performance of wireless activities using 5G will be significantly faster than 4G LTE. What may have taken minutes to load on 4G would only take a few seconds on 5G.

While the most advanced 4G available (4G LTE Advanced) offers 1 Gbps, new 5G would bring speeds of up to 20 Gbit/s. To accomplish this, the existing LTE frequency range will be more thoroughly used while also adding new Millimeter wave bands.


Latency

Another important feature in improving wireless connections is latency. 5G provides ultra-low latency, much lower than what’s capable with 4G. As connections begin to respond in real-time, 5G can even be used for mission critical and emergency applications, like medical equipment.


Connection Density

The technology used to bring 5G to life will bring greater reliability to wireless connectivity in areas with greater interference. By deploying small cells, which are low-powered cellular Radio Access Networks, providers can set up their own centralized networks in more areas. The wireless infrastructure consists of both small cells and macrocells, and the combination of the two allow for greater coverage.


Here is a table summarizing the capabilities of 5G:

Capability

Description

5G Target

Peak data rate

Maximum achievable data rate

20 Gbit/s

User experienced data rate

Achievable data rate across coverage area

100 Mbit/s

Latency

Radio network contribution to packet travel time

1 ms

Mobility

Maximum speed for handoff and QoS requirements

500 km/h

Connection density

Total number of devices per unit area

106/km2

Energy efficiency

Data sent/received per unit energy consumption (by device or network)

Equal to 4G

Spectrum efficiency

Throughput per wireless bandwidth and per network cell

3-4x 4G

Area traffic capacity

Total traffic across coverage area

10 (Mbit/s)/m2

 

Applications for 5G

Some of the key applications that would benefit from 5G are IoT applications like smart grids, smart medicine, connected cars, and sensors in an IoT environment. 5G opens up wireless connectivity past mobile connectivity and into IoT and critical communication segments.

 

Looking ahead

Worldwide commercial launch of 5G is not expected to occur until 2020. While many operators have already demonstrated 5G, the infrastructure to build 5G will take time.

We have much to look forward to as 5G approaches. Not only will our current wireless applications operate at faster speeds with better efficiency, 5G will open up newer technologies that cannot exist until 5G speeds arrive.
