What Are The Differences Between The 8 Ways Of 5G SA And NSA?
Jun 23, 2018

5G is the fifth generation communication technology. Compared with the first four generations , 5G is not only applied to mobile communication technology, but also to the Internet of Things. It mainly includes three major application scenarios, eMBB (enhanced Mobile Broadband), mMTC. (massive Machine Type Communications) and URLLC (Ultra-Reliable and Low Latency Communications), where mMTC includes eMTC (enhanced Machine Type Communications) and NB-IoT (Narrow Band Internet of Things).

Both eMTC and NB-IoT are LWPA (Low Power Wide Area) technologies within the 3GPP standard, and they both compete with each other and supplement each other. There are many similarities between the standardization process, industrial development, and existing network applications, but at the same time there are some differences in mobility, speed, and cost. If there are high requirements for voice, mobility, speed, etc., eMTC technology can be selected. If these requirements are not high, but the cost, coverage and other requirements are higher, you can choose NB-IoT technology.water blocking yarn

To implement 5G applications, you first need to build and deploy 5G networks. The deployment of 5G networks requires two parts: the radio access network (RAN) and the core network. The radio access network is mainly composed of base stations and provides users with wireless access. The core network provides users with Internet access services and corresponding management. Due to the huge investment in deploying new networks and the need to deploy these two parts separately, the 3rd Generation Partnership Project (3GPP) is divided into two ways to deploy SA (Standalone) and NSA (Non-Standalone). The SA refers to the creation of an existing network, including new base stations, backhaul links, and core networks. The NSA refers to the deployment of 5G networks using the existing 4G infrastructure.

In the standards established in June 2016, 3GPP has listed eight 5G architecture options, including Option1, Option2, Option3/3a, Option4/4a, Option5, Option6, Option7/7a, and Option8/8a. Among them, Option1, Option2, Option5, and Option6 are SA modes, and the rest belong to NSA modes.filling compound for optical fiber cable

In the March 2017 release, preference was given (and two sub-options 3x and 7x were added): Option 2, Option 3/3a/3x, Option 4/4a, Option 5, Option 7/7a/7x, etc. 5 5G architecture options. There are two options Option2 and Option 5 left in the SA mode.glass yarn
