Open RAN: the new 'open' mobile network launched in Faenza

05/12/2021 - 11:00 AM

Faenza is the starting point for TIM's Open RAN revolution, the Open Radio Access Network technology that makes it possible to create new-generation mobile networks, increasing performance and the flexibility of the services they offer.

Open RAN is one of the most important evolutions of the mobile access network being developed internationally. This is an initiative led by the Open RAN Alliance, the international group which has been bringing some of the leading telecommunications operators, including TIM, together since February 2018. The aim is to develop mobile infrastructures with open interfaces, thus facilitating collaboration between different actors.

Thanks to the development of Open RAN solutions, new standards are being defined that make the development of antennas and radio access network hardware and software components independent, so that different industrial players can offer solutions that are interoperable with those of other operators. This fosters the growth of a broader and more diverse industrial ecosystem and opens the door to start-ups and other innovators, reducing the time it takes to develop new services for customers and businesses.

Among the technologies at the heart of this evolution is 5G, which, together with the Cloud and Edge Computing, will make the widespread dissemination of increasingly secure and advanced digital services for people, businesses and the public administration possible. This includes services linked to new solutions for Industry 4.0, smart cities and autonomous driving.

The first city in Italy to adopt this open network model is Faenza, where TIM has set up a mobile radio network in collaboration with JMA Wireless - a leader in mobile coverage activities and in the development of Open RAN software and Microelectronics Technology (MTI).

Open RAN Alliance activities are ongoing, leading to the definition of guidelines for the technological priorities that will guide the development of standards for new mobile networks across Europe.

Technical Priority Documents – March 2022

This Open RAN Technical Priorities Release 2 is an update of the document published in June 2021. It is the result of the work carried out under the MoU on Open RAN signed by Deutsche Telekom AG, Orange S.A., Telefónica S.A., TIM S.p.A. and Vodafone Group Plc.

Release 1 focused on the main scenarios and technical requirements for each of the building blocks of a multi-vendor RAN. Release 2 builds on those requirements and focuses on intelligence, orchestration, transport and cloud infrastructure, with the aim of promoting a fully automated and interoperable Open RAN system.

The energy efficiency goals and targets to support sustainable Open RAN deployments have also been addressed. It is expected that Open RAN networks will gradually become more energy efficient than traditional RAN, benefiting from Open RAN concepts such as cloudification, disaggregation and native AI.

The overall objective is to promote a fast pace for the development of competitive Open RAN solutions in Europe, across other regions and ultimately accelerate the global adoption of the technology. These requirements will evolve over time following the progress of Open RAN standardisation and market development of Open RAN solutions.

Security White Paper – March 2022

The ‘Open RAN Security White Paper’ is the result of the work carried out by the security experts of Deutsche Telekom AG, Orange S.A., Telefónica S.A., TIM S.p.A. and Vodafone Group Plc being the signatories of the Open RAN MoU.

This document starts with an introduction of the MoU framework, and the O-RAN Alliance organisation and its activities. It focuses on all security aspects within Open RAN technology, describing the risk-based threat modeling and remediation analysis conducted within the O-RAN Alliance for building an effective Open RAN security architecture.

In addition, it provides details on the Open RAN Security Focus Group (SFG) activities, which focuses on developing the four security specifications that are the pillars of the Open RAN security architecture. These include threat modeling, security requirements, protocols and tests.

Near Real Time Radio Intelligent Controller – November 2021

During the Open RAN Plugfest 2021, held in November in the TIM Innovation lab in Turin, TIM developed the Near RT RIC in collaboration with Keysight.
It is a software platform that collects network data in real time so that they can be analysed by various applications: then Machine Learning techniques are used to find possible problems and identify improvements in the functioning of the 4G / 5G network.

Open RAN Technical Priorities - Executive Summary

As a result of the work carried out under the MoU on Open RAN signed by Deutsche Telekom AG, Orange S.A., Telefónica S.A., TIM and Vodafone Group Plc we are publishing the executive summary of the Open RAN Technical Priorities with a list of requirements to guide and foster a competitive open RAN ecosystem, promoting openness and flexibility.

The overall objective is to ensure a fast pace for the development of open and virtualized RAN solutions while ensuring they reach parity with best-in-class traditional RAN solutions, and support a timely roll-out of open RAN networks in Europe.

The comprehensive list of Open RAN technical priorities will be published shortly.

Open RAN Technical Priority Document, by the Open RAN MoU signatories - June 2021

The “Open RAN Technical Priorities Document” is the result of the work carried out under the MoU on Open RAN signed by Deutsche Telekom AG, Orange S.A., Telefónica S.A., TIM and Vodafone Group Plc. This document offers a comprehensive list of technical requirements that the signatories of the Open RAN MoU consider priorities for Open RAN architecture to guide and foster a competitive open RAN ecosystem, promoting openness and flexibility. It includes the main scenarios and radio configurations targeted for operators’ deployment, providing hardware and software requirements for each of the building blocks of a disaggregated RAN. The overall system relies on open interfaces to allow multi-vendor deployment in a fully interoperable manner, and intelligent radio controllers and orchestration in a cloud-native environment to unleash the potential of a fully automated network. The overall objective is to promote a fast pace for the development of open, virtualized and programmable RAN solutions, and support a timely roll-out of open RAN networks in Europe
