Study Notes

5G Technology

The maximum user-experienced data rate in urban/suburban areas is 1 Gbps.

Orthogonal Frequency Division Multiplexing (OFDM)

The main idea behind OFDM is to divide a high-rate data stream into multiple low-rate streams, modulating each stream on a separate subcarrier, and transmitting them simultaneously over the same channel.
The main problem with OFDM is spectrum overflow, where the signals from adjacent subcarriers interfere with each other.

New Radio Multiplexing Technology

The new radio multiplexing technology divides the band into multiple sub-bands, each using different OFDM parameters.

Peak Data Rate

The maximum peak data rate per user under ideal conditions for mobiles is 20 Gbps.
