The technology gives 5G enhanced flexibility for a multitude of use cases, enabling it to support diverse spectrum bands, including mmWave bands with far higher available bandwidth, through the use of specialized technologies like scalable subcarrier spacing and massive MIMO, absolutely necessary for the implementation of radio beam steering and forming to mitigate propagation challenges in mmWave communications. This meant that major improvements in existing 4G networks, such as LTE Advanced and LTE Advanced Pro, will support sub-6 GHz 5G, and faster, more reliable, and scalable networks will begin delivering services as soon as carriers deployed them.ĥG utilizes OFDM (orthogonal frequency-division multiplexing), a waveform modulation technique also used by both LTE and IEEE 802.11 (Wi-Fi). They were fast-tracked two years ago to enable non-standalone technologies to begin operating as soon as possible. The first 5G NR specifications were part of 3GPP’s RAN Evolution of LTE documented in Release 14, begun in June 2016. Like LTE (long term evolution), the term describes a group of technologies that enable a range of speeds and capacities. The radio access technology (RAT) developed for 5G by 3GPP includes two frequency ranges: FR1, which operates below 6 GHz, and FR2, which includes bands above 24 GHz and into the extremely high frequency range above 50 GHz.ģGPP has dubbed 5G’s new air interface 5G NR (New Radio).

The new mobile network technology has already begun using the current architecture of LTE to support non-standalone (NSA) 5G, on the way to full standalone (SA) infrastructure that does not rely on 4G.

5G has set a new standard for wireless, opening up the spectrum above 6 GHz that has been previously unusable by cellular services.
