R&S Technical Explainer on 3GPP 5G Non Terrestrial Networks (NTN)

I have explained Non Terrestrial Networks (NTN) earlier here and have written a detailed article here. The initial 3GPP Release-15 version of 3GPP TS 22.261 added the initial requirement that the 5G system will be able to provide services using satellite access. A study was carried out by 3GPP as a part of 3GPP Release-16 and the results of the study on using satellite access in 5G networks have been documented in 3GPP TR 22.822. The document details the use cases, pre and post conditions, service flows, potential impacts / interactions with existing services / features and potential requirements based on the use case. The results from this technical report (TR) were then reflected in 3GPP Release-16 version of 3GPP TS 22.261. The document details the need for the 5G system to support service continuity between terrestrial 5G access and satellite based 5G access networks, owned by either the same operator or by an agreement between operators.

3GPP Release 17 will bring some interesting changes in the 5G NR standardization. The R&S explainer focuses on the future of non-terrestrial networks (NTN) and possible applications. In addition, it explores some NTN deployment scenarios and technology challenges.


I liked this NTN in one slide picture. Anyway, the talk is embedded below.

High-level Architecture Introduction of Mobile Cellular Networks from 2G to 5G

Here is an old tutorial explaining high level mobile network architecture, starting from GSM and then looking at GPRS, UMTS, LTE & 5G.

5G Connectivity will Enable New Use Cases

While we have been discussing advanced 5G use cases for years, it is only now, with the Standalone 5G (5G SA) that it is going to become possible to have many of these in practice. Of course they will take time to mature and be popular with the end users. As a part of our Free 5G Training initiative , we made a short video that will provide you with ideas and motivation for why 5G could do a lot more than just faster speeds. The video is embedded below. In addition, Parallel Wireless, one of the companies I consult for, did a webinar on 5G Use Cases which is available here .

Fixed Wireless Access (FWA) and the Path to 5G Wireless Wireline Convergence (WWC)

I have covered Fixed Wireless Access (FWA) on The 3G4G Blog here and looked at automated HetNet design which included FWA links here . I have also covered Wireline Wireless Convergence (WWC) as part of 5G and Fixed-Mobile Convergence (FMC) posts. The links to the posts are available at the end. Back in December, Juniper took part in a Light Reading webinar which is being shared as part of this post. With revenues flat and traffic continuing to explode, the unsustainable state of network economics needs another disruption. The 5G deployment cycle offers an insertion opportunity for new converged architectures. Wireless offload solutions can re-route the traffic of data-hogging mobile subscribers over wireline cores built for bandwidth and performance rather than mobile cores (EPC) primarily designed for mobility and portability. The 5G Network Architecture in 3GPP Release-16 allows the convergence of fixed and wireless networks. This also allows many new opportunities as can be se
