TIM’s 5G overcame the 2 Gbps speed, a new European record achieved on the mmWave live network

TIM confirms its leadership in 5G innovation and in the development of next-generation networks and services by successfully completing the first connection in Europe able to permanently overcome the 2 Gbps speed on a 5G live commercial network with 26 Gigahertz (GHz) millimeter-wave (mmWave) frequencies acquired through MiSE’s 5G bid.

TIM has achieved this key record together with Ericsson and Qualcomm, two NGMN partners, and this represents an additional milestone regarding millimeter-wave to those already achieved in Turin in 2017 through the first 5G connection in Italy and in Rome in 2018, with the first 5G videocall in Europe.

This result marks a significant milestone toward 5G evolution, kicking-off the use of 200 MegaHertz (MHz), acquired through MiSE’s bid on 26 GHz spectrum, in addition to further 200 MHz available thanks to the bid’s Club Use[1], for a total amount of 400 MHz. The performances achieved will improve significantly during 2020, as the network will be able to use up to 800 MHz and afterwards up to 1.000 MHz.

Being able to achieve Gbps speeds and provide with high network capacity thanks to the wide bandwidth available, 26 GHz mmWave frequencies fit the further development of 5G Fixed Wireless Access (FWA) services both in the areas not yet covered by fixed ultrabroadband and the creation of “dedicated” 5G indoor coverage. Furthermore these features enable new Industry 4.0 scenarios based on services with exceptional high speed, extremely low latency and the highest security and reliability levels.

TIM achieved the significant milestone grounded on a standard 3GPP Non-Stand Alone (NSA) solution able to let devices and network components from different providers interacting and to aggregate TIM’s 4G and 5G network, already implemented in 3.7 GHz spectrum.

Michele Gamberini, TIM’s Chief Technology and Information Officer commented: “TIM has been pioneer in the millimeter-wave spectrum innovation and with this new European 5G record the company confirms its technological leadership, thanks to its strive toward innovation and a cutting-edge network infrastructure, able to enable the entire country’s digital transformation. This milestone paves the way to the development of new 5G solutions to grant fixed ultrabroadband to families, companies and public authorities not yet covered. This also includes coverage dedicated to the development of robotics and automation digital services in the smart manufacturing area. All of our customers will therefore be able to take advantage of a wide range of integrated solutions that will allow them to fully enter the Digital Society.

Emanuele Iannetti, Country Manager at Ericsson Italy, says “5G will be the main innovation platform of the next decade and it will allow Italy to be increasingly competitive and attractive in the global scenario. We are extremely pleased that TIM has chosen Ericsson’s 5G technology to achieve this important milestone, placing our country at the forefront of the commercial implementation of the fifth generation of mobile networks. Ericsson thus confirms its technological leadership and its readiness to anticipate any market demands.

“Qualcomm Technologies congratulates TIM on this significant milestone which again demonstrates the potential of 5G mmWave technology and shows how operators are able to use a wide range of spectrum bands to deploy 5G. 2020 will see a significant expansion in 5G coverage and the use of mmWave bands will play a clear role in the build-out”, said Enrico Salvatori, president, Qualcomm EMEA.

[1] 26GHz Club Use means the possibility – exclusive for 5G millimetre-wave spectrum assignees – to use the full 1 GHz band if not used by other assignees

Small Cell Cost Sharing

Ideas for Small Cell Cost Sharing – Short Report

There 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

This NGMN report aims 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 possibly anchored to an LTE coverage layer). This study considers different economic models (including such as independent “neutral host” or jointly owned infrastructure companies) as well as technology aspects.

Non-Terrestrial Networks Position Paper

NGMN’s Extreme Long-Range Communications for Deep Rural Coverage project presented in paves the way for the study of cellular coverage for sparsely populated areas. In this study, a number of Mobile and Satellite Technologies that could provide coverage to remote areas have been analysed and studied.

The present paper elaborates on that recommendation, providing an overview and analysis of non-terrestrial cellular technologies that can provide coverage to remote areas.

The aim of this work is to illustrate how 5G end-to-end deployment can meet vertical requirements and also highlight what are the main 5G URLLC technology enablers for use cases identified in the report. Some of these new use cases impose extremely low latency and high reliability requirements on 5G system from end-to-end perspective. This report also briefly describes 5G URLLC enablers along with reference architecture for specific use case and further evaluate how 5G URLLC can enable such use cases.

Continuous Delivery in Telecom Networks

Continuous Delivery in Telecommunication Network Environments

Today, production networks are strictly separated from test networks and development environment networks for security and operational reasons. This gap between “Continuous Integration” automation in one network zone and deployment automations in other network zones hinders seamless “Continuous Delivery” automation.

This white paper focuses on solving the this challenge.

5G E2E Architecture Framework

5G End-to-End Architecture Framework v3.0.8

The purpose of this document is to provide a high-level framework of architecture principles and requirements that provide guidance and direction for NGMN partners and standards development organisations in the shaping of the 5G suite of interoperable capabilities, enablers, and services. It builds on the architectural concepts and proposals implied by the NGMN White Paper and subsequent deliverables published by NGMN.

 

The elements of functional virtualisation shift of computing to the edges of the network, and leveraging of spectrum distribution and flexibility, are among the dominant themes that shape the 5G ecosystem. Optimisation of operational and performance efficiencies, while creating and delivering an exceptional and customisable user experience is of paramount significance.

Joint NGMN/WBA RAN Convergence White Paper

Joint NGMN/WBA RAN Convergence Paper

In order to examine the best future solutions for convergence of Wi-Fi and 5G, this paper examines the current Wi-Fi interworking solutions available for 4G systems using either trusted or untrusted Wi-Fi access, through either Core Network based or RAN level integration. It also reviews the 3GPP 5G system approach to Wi-Fi access, which includes integration of untrusted Wi-Fi access in Release 15 and the new opportunities in Release 16 for trusted Wi-Fi access as well as wireline and cable modem access such as from a residential gateway. Release 16 specified Access Traffic Steering, Switching and Splitting (ATSSS) functionality is analyzed which enables data session over one or more concurrent accesses.
