Recommendation on Base Station Active Antenna System Standards
//in Publications //by Klaus MoschnerThe main scope of this White Paper is to describe and capture the electrical and mechanical key performance parameters of Active Antenna Systems and how to exchange this data electronically.
In addition, for the aim of RF-Electromagnetic Field exposure, a description of mechanisms to monitor and limit the power radiated by Active Antenna Systems is provided.
NGMN Security Consideration of Low Layer Split in O-RAN
//in Publications //by Klaus MoschnerIn this Liaison Statement from NGMN to the O-RAN Alliance, the NGMN Alliance informs O-RAN that the security of low layer split in O-RAN needs to be globally considered. Security considerations on threats depend on the deployment model and use case. NGMN therefore proposes a two-phase approach to mitigate such threats.
5G Devices Categorization
//in Publications //by Klaus MoschnerThe purpose of this document is to provide a use-case based categorization of 5G Devices implementing 3GPP Rel-15 relevant Technical Specifications.
In particular, 5G Devices coming to market between 2H 2019 and 1H 2020 are addressed.
For each 5G Devices category (among eMBB, Fixed Wireless Access and Industrial), a set of mandatory and recommended features is defined.
Pre-Commercial Networks Trials Major Conclusions
//in Publications //by Klaus MoschnerGiven the freeze of 3GPP Release 15 5G standards and the onset of some initial 5G commercial deployments in countries such as South Korea, many operators accelerated their 5G trials in 2019.
As a part of NGMN 5G Trial and Testing Initiative (TTI) project, some major NGMN operators, shared their initial 5G trial results.
Pre-commercial network trials phase of 5G TTI aims to consolidate the results from different operators and reach some major conclusions.
Overall, this consolidation effort, which gathers Trial reports mostly performed using a common methodology, permits to draw some very promising conclusion on the performances of early 5G implementations. Additionaly, it brings as well some observations that could lead to future improvements.
Ideas for Small Cell Cost Sharing – Short Report
//in Publications //by Klaus MoschnerThere is a long held vision of very high capacity networks using small cells in areas of high demand. With the expected availability of large quantities of mmWave spectrum for 5G, this opportunity in principle becomes even greater. But the economics of small cell deployment have proved very challenging in practice – and this challenge will only increase at mmWave frequencies, where coverage of an individual cell is typically even smaller. Unless the industry can find ways to reduce the per cell building, operation and maintenance costs, the opportunity to build out small cell networks using mmWave spectrum will be severely constrained.
NGMN carried out a study to identify and assess different approaches to improving the economics of small cells through some form of cost sharing between operators (with 5G small cells typically anchored to a 5G or LTE coverage layer). This short public report presents the most important and interesting ideas arising from that study. A fuller report from the NGMN study is also available
