Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the medium access control (the channel ...
The performance of each technology is determined by a number of constraints, including the spectral efficiency of the technology, the cell sizes used, and the amount of spectrum available. For more comparison tables, see bit rate progress trends , comparison of mobile phone standards , spectral efficiency comparison table and OFDM system ...

Spectral efficiency should be significantly enhanced compared to 4G. Coverage should be improved. Signalling efficiency enhanced. Latency should be significantly reduced compared to LTE. [4] Next Generation Mobile Networks Alliance feels that 5G needs to be rolled out in 2021-2023 to meet business and consumer demands. [5]
An Android phone, showing that it is connected to a 5G network An Apple iPhone showing that it is connected to a 5G Network. In telecommunications, 5G is the fifth generation of cellular network technology, which mobile operators began deploying worldwide in 2019 as the successor to 4G. 5G is based on standards defined by the International Telecommunication Union under the IMT-2020 ...
Have peak link spectral efficiency of 15 bit/s·Hz in the downlink, and 6.75 bit/s·Hz in the up link (meaning that 1 Gbit/s in the downlink should be possible over less than 67 MHz bandwidth). System spectral efficiency is, in indoor cases, 3 bit/s·Hz·cell for downlink and 2.25 bit/s·Hz·cell for up link. [5]
