NSA (Non-Standalone Access) and SA (Standalone Access) are the two 5G network modes . NSA relies on the 4G network facilities to provide more speed and higher data bandwidth. A 5G-enabled smartphone will connect to a 5G or 4G network depending on conditions.
Read moreWhat is NR NSA and NR SA?
NSA adopts dual connection mode, 5G NR control plane is anchored to 4G LTE, and utilizes the old 4G core network EPC. SA and 5G NR are directly connected to the 5G core network (NG Core). It no longer relies on 4G and is a complete and independent 5G network.
Read moreWhich 3GPP release version is the first phase of 5G specification?
After initial delivery in late 2017 of ‘Non-Stand-Alone’ (NSA) NR new radio specifications for 5G, much effort focused in 2018 on timely completion of 3GPP Release 15 – the first full set of 5G standards – and on work to pass the first milestones for the 3GPP submission towards IMT-2020.
Read moreWhich are the 3GPP 5G releases?
The planned dates for Release 17’s physical layer, functionalities and protocol work freezes are December 2021, March 2022 and June 2022 , respectively. This timeline assumes 3GPP will resume in-person meetings from June 2021 onward, yet is likely subject to change depending on the continued threat of COVID-19.
Read moreWhat problem does 5G solve?
5G will solve issues that have plagued existing technologies for years, such as pixelated video calls, long buffer times for streamed movies, and delays between uploading and sharing content .
Read moreWhat does 5G run on?
A: 5G is based on OFDM (Orthogonal frequency-division multiplexing) , a method of modulating a digital signal across several different channels to reduce interference. 5G uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.
Read moreWhat is 5G core and ran?
RAN and core are both critical components of 5G networks because gNBs (5G base stations) terminate the encryption of user data, except when it is encrypted externally and is beyond the control of an operator’s 5G network. As a result of this, gNBs have full access to all data to and from devices in cleartext.
