How 5G is Going to be Different?

Fourth generation of mobile connectivity started to make waves back in early 2010s. 4G made mobile internet speeds up to 100 times faster than 4G and allowed support for HD video streaming, high-quality phone calls through VoLTE and faster mobile browsing.

4G is now common throughout the world. However, this evolution is endless. Things are about to change again. Internet of things is a thing now(!). But 4G will not be able to manage the huge number of connections on the network. More than 20 billion devices are going to be connected by the end of 2020. This will require massive network capacity. This is where we need 5G.

5G being faster, smarter and more efficient than 4G is a no-brainer. But low-latency is a key differentiator beween 4G and 5G. Latency is the time from the moment the information is sent from a transmitter until it can be used by the receiver. Low latency means the 5G mobile connection can server as a replacement for Wi-Fi/ADSL/cable modem.

Additionally, 5G can fix bandwidth issues. 5G will be able to handle a massive number of connected devices. This will be able to expand the scope of 5G not just for mobile devices but even for emerging technologies such as connected cars, smart homes and IoT.

Following are the International Mobile Telecommunication-2020 (IMT-2020 standard) requirements put forward by Radiocommunication sector of International Telecommunication Union (ITU-R) for 5G networks:

IMT 2020 Requirements for 5G

Capability5G Requirement
Theoretical max downlink data rate20 Gbps
Theoretical max uplink data rate10 Gbps
User experienced max downlink data rate100 Mbps
User experienced max uplink data rate50 Mbps
Latency1-4 ms
Connection density1,000,000 devices per sq. km.
Energy efficiency (by network or device)Equal to 4G

That’s all about how 5G is going to be different! I will keep you updating on the same as new information becomes available in coming months.

In next post, I will elaborate about radio frequencies to be used by 5G networks.
