Introduction of 5G Network
In telecommunications, 5G is the fifth-generation technology standard for broadband cellular networks
which cellular phone companies began deploying worldwide in 2019
5G networks are predicted to have more than 1.7 billion subscribers
5G speeds will range from around 50 Mbps to 1,000 Mbps (1 Gbps) depending on the RF channel and BS load.
In 5G, the ideal "air latency" is of the order of 8–12 milliseconds
Latency is much higher during handovers; ranging from 50 to 500 milliseconds depending on the type of handover.
5G uses adaptive modulation and coding scheme (MCS) to keep the bit error rate (BLER) extremely low.
Initially, the term was associated with the International Telecommunication Union's IMT-2020 standard
5G NR can include lower frequencies (FR1), below 6 GHz, and higher frequencies (FR2), above 24 GHz
The 5G system architecture is defined in TS 23.501.
