Question

Discuss how 5G communications can achieve higher throughput than 4G?

Answer 1

5G is not only about increasing the speed but also reduction in network latency and thats the reason 5G is associated with IOT.

Latency becomes difficult to quantify because it varies on network conditions. 5G latency will be lowered by factor of 60 to 120 when compared to 4G.

5G will use wavelength of frequencies between 30 to 300 GHz range than 4G used less ones which made 4G to carry less.

5G deploys advanced beamforming technique to make sure all all conversations go back and forth using constructive and destructive radio interference which was lacking in 4G.

5G covers wireless transfer which already increases the speed.

Here are some comparisons between 5G and 4G:

   5G 4G

------------------------------------------------------------------------------------------------------------------------------------      

Peak Speeds 10 Gigabits/sec   1.4 Gigabits/sec

Latency < 10 milliseconds <40-50 millisecons

Connectivity 1 million devices/sq mtr 10k-100k devices / sq. mtr.

Energy Efficiency 90% less energy used /bit 90% high energy used /bit

Mobile Data Volume 10 terabytes/s/sq.km² 1/100 terabytes/s/sq.km²
