Extreme Long Range Communications for Deep Rural Coverage (incl. airborne solutions)

In this document reasoning for providing coverage for sparsely populated areas are presented along with a number of Mobile and Satellite Technologies that could provide coverage to remote areas. There is a sound business justification to provide affordable Voice and Data Services for sparsely populated areas, such as Sub-Sahara Africa, but also for higher ARPU markets with wide rural areas, such as North Canada. Mobile network operators worldwide have both economic and social incentives to offer services to rural residents, but efficiently serving dispersed populations with current technologies is difficult and rural access lags significantly behind urban access. For many network operators, who want to expand addressable markets and satisfy users interest or who under regulatory obligations or social responsibilities willingness must cover vast areas of sparsely populated regions, a cost-effective technology is essential which on one hand provides adequate voice and data services and other hand is economically sustainable to deploy and to maintain. The purpose of the NGMN’s Extreme Long Range Communications for Deep Rural Coverage program is to explore the challenge of addressing rural markets and to create industry momentum around long range communications solutions that are suitable for offering Internet access to rural populations who are underserved today....

5G Trial and Testing Initiative - Proof of Concept Major Conclusions

Architectural Highlights/Gaps: CU/DU split: the need for open interface F1 and functional split agreement CP/UP split: beyond current 3GPP standardization, but widely embraced by the operator community; heated discussion on open interface E1 and multi-vendor, RRM implementations in O-RAN, etc. Fronthaul: the fact that we have not been able to achieve FH testing in PoC phase is due to lack of well-established interface, but hopefully in PCNT. Performance Statements: We saw most of the performance KPI results are meeting with the PoC success criteria Some of the KPIs didn’t meet criteria, which was due to functionality or feature missing implementation or due to environmental constrains. We recommend these to be checked during pre-commercial trial phase.

Recommendation on Base Station Antenna Standards (V11.1)

This whitepaper addresses the performance criteria of base station antennas, by making recommendations on standards for electrical and mechanical parameters, by providing guidance on measurement and calculation practices in performance validation and production, and by recommending methods for electronic data exchange.  It also addresses recommendations on applying existing environmental and reliability standards to BSAs.

NGMN Recommendations on Cooperative Intelligent Transport Systems (C-ITS)

In a letter from the NGMN board members to the European Commission, NGMN reiterates its position to adopt a forward-thinking, technology-neutral approach in developing the EU’s C-ITS (Cooperative Intelligent Transport Systems) strategy. The letter, addressed to EC President Jean-Claude Juncker, calls upon European legislators to reconsider the current EC Draft Delegated Act in order to include cellular vehicle-to-everything (C-V2X) on the list of available/mature technologies that European stakeholders may utilise, therefore allowing the market to develop most effectively.

RAN Convergence Paper

NGMN and Wireless Broadband Alliance (WBA) have published the first results of their collaboration to drive the convergence of multi-technology RANs and core networks. The joint report identifies a number of emerging opportunities and use cases that the industry can benefit from through the convergence of 5G and Wi-Fi, driven by the ever-enhancing capabilities of licenced and unlicensed technologies. It also highlights the key challenges which must first be addressed in order to realise this convergence – including tighter integration of Wi-Fi access in 5G networks, network manageability and policy control, and the enablement of Wi-Fi-only devices.

Definition of the Testing Framework for the NGMN 5G Pre-Commercial Network Trials (Version 2)

This document (Version 2) focuses on the pre-commercial network trials phase of the NGMN 5G Trial & Testing Initiative which has the following scope: Developing a testing framework for 5G New Radio (NR), as developed by 3GPP, allowing the harmonization of the testing methodologies between the different parties conducting trials. Devising a strategy for the trials activities to guarantee efficiency and success of the different trials activities. Testing 5G capabilities in realistic conditions with pre-commercial equipment.

NGMN Recommendations on Cooperative Intelligent Transport Systems (C-ITS)

In a letter from the NGMN board members to the European Commission, NGMN strongly recommends to adopt a forward-thinking, technology-neutral approach in developing the EU’s C-ITS strategy. The letter, addressed to EC President Jean-Claude Juncker, calls upon European legislators to reconsider the current EC Delegated Act by including C-V2X on the list of potential technologies that European stakeholders may pursue and allow the market to decide which technology prevails. The board urges that given its importance, the Delegated Act adoption should not be rushed but conducted in transparent consultation with all stakeholders. A recent white paper on V2X technology published earlier this year by NGMN was also included, outlining the advantages of cellular technology over the less desirable wi-fi technology currently being considered.

Security Aspects of Network Capabilities Exposure in 5G

5G network is expected to expose some of its capabilities to 3rd parties in order to catalyze the creative services based on them. The exposed network capabilities should thus create new business opportunities, but may also introduce new security risks. The security considerations depend on the exposure scenarios, the local regulation constraints, business models, and trust/liability models among the service user, the network capability provider (i.e., the network operator), and the network capability consumer (i.e., the 3rd party). The scope of this document is: To identify different network capabilities exposure scenarios; To investigate and propose security requirements for these scenarios; To investigate the exposure of security capabilities and present and evaluate the corresponding use cases. The main purpose of this document is: To help the network operators and their partners to find secure and beneficial ways of exposing the network capabilities; To influence the 5G-related standardization work in 3GPP (in particular, in SA3, SA1, SA2 and SA6) as well as in other SDOs.
