 How does 5G Works?

5G technology

 Compared to 4G, which runs at frequencies between 3 and 120 GHz, 5G has a broader bandwidth. However, 5G can operate in mmWave (24GHz) and both lower bands. It is the add-on for the next generation which will bring more capacity.

Orthogonal frequency-division multiplexing (OFDM), is the foundation of 5G. It is a technique for modulating a digital transmission across several channels to reduce interference. In another word, it is a method of data transmission where a single information stream among the several closely spaced narrow-band subchannel frequencies will be increased when it slit into the subchannel speed of data transmission increases. 5G employs the 5G NR air interface in addition to OFDM concepts. Wider bandwidth technologies like mmWave and sub-6 GHz are also used in 5G.

5G OFDM functions using the same mobile networking concepts as 4G LTE. The new 5G NR air interface, however, has the potential to improve OFDM to give a significantly better level of flexibility and scalability. This may increase the number of people and things who have access to 5G for a range of use cases.
