Nokia today announced the availability of a software based upgrade that will enable its 4G/LTE radios to be migrated seamlessly to 5G/NR.
These features will have a high value to Nokia’s customers as they provide immediate support for approximately one million radios, reaching 3.1 million by the end of the year and over 5 million in 2021. By upgrading existing radio elements via software, Nokia is helping to streamline the process of refarming 4G/LTE spectrum into 5G/NR. The move will also support existing customers and the installed base by offering a seamless and cost-effective upgrade path to 5G/NR.
Most of the 5G/NR deployments to date have been performed with TDD cmWave and TDD mmWave deployment but the next big wave of 5G/NR rollouts will be delivered by refarming existing FDD bands to 5G/NR. TDD spectrum benefits from enlarged coverage and capacity when combined with already deployed FDD network infrastructure and spectrum bands via TDD/FDD Carrier Aggregation.
The ability to upgrade 4G/LTE radios via a software update will significantly smooth out the deployment of 5G/NR FDD, avoiding costly and disruptive site visits. Nokia has a vast customer base of 359 4G/LTE customers with deployed FDD RF units most of which are possible to upgrade. This will provide a new and smoother way for operators to build 5G/NR coverage in lower bands via spectrum refarming. Nokia’s 4G/LTE radios are market leading and outperform all vendors according to independent testing.
Nokia also has Dynamic Spectrum Sharing (DSS) already in live networks covering 2G/GSM-3G/WCDMA-4G/LTE and recently introduced DSS for 4G/LTE-5G/NR. This capability completes a DSS solution, covering all access technologies and making the radio frequency refarming to 5G/NR a simple and efficient process.
In a typical case DSS will be introduced to one or few 4G/LTE bands which are then combined with carrier aggregation between other bands running pure 4G/LTE or 5G/NR. Nokia has the market leading DSS solution covering all radio access technologies from 2G/GSM to 5G/NR.
Nokia estimates that this solution will save the telecommunications industry potentially tens of billions of euros in site engineering and re-visit costs as communication service providers are able to upgrade their networks to 5G/NR on FDD with software.
Chris Nicoll, Principal Analyst at ACG Research, said, "While Open RAN promises software upgradability to ease transitions between ‘Gs’ and add new features, Nokia’s Flexi and AirScale portfolio shows it is ahead of the game by providing a software upgrade to transition over 5 million 4G radios to 5G. Efficient FDD spectrum refarming is critical for fast, broad and deep 5G deployments. With Nokia supplying the majority of the world’s top 4G operators, supporting key advanced features such as DSS helps those operators lead with 5G.”
“We already provide market- leading LTE radios to hundreds of customers around the world. This is an important solution because it will help our customers, quickly and efficiently upgrade their existing LTE radios so that they are 5G ready saving them time and money.”
Ericsson has joined the O-RAN Alliance, a group of leading telecom service providers and suppliers with the commitment to evolving radio access network (RAN) architecture and orchestration built on openness, intelligence, flexibility and performance.
As a member, the company will focus on the open interworking between RAN and network orchestration and automation, with emphasis on AI-enabled closed-loop automation and end-to-end optimization, to lower operating cost and improve end-user performance.
Ericsson will also focus on the upper-layer function as specified in 3GPP to provide interoperable multivendor profiles for specified interfaces between central RAN functions, resulting in faster deployment of 5G networks on a global scale.
Erik Ekudden, Senior Vice President and Chief Technology Officer, Ericsson, says: “Ericsson is a strong supporter of openness in the industry, and the benefits this has on global ecosystems and innovations. Our ambition is to actively support and drive discussions and developments around future RAN architectures and open interfaces. The O-RAN Alliance is an important coalition that creates an arena for these discussions, complementing other standardization and open-source initiatives in the industry which we are already active in.”
Ericsson has driven, and continues to drive, the industry towards open interfaces as part of its standardization work. The company is recognized as leaders in 3GPP and is actively contributing to several open-source communities including Linux, ONAP and OpenStack to secure open platforms useful for mobile networks.
The company’s engagement with the O-RAN Alliance is based on the future needs of mobile network service providers, and how networks must evolve to enable broad range of services with strong focus on quality, performance and security.
The O-RAN Alliance was formally formed at Mobile World Congress Shanghai on June 27, 2018 as a network operator-led effort to drive openness and intelligence in the RAN of next-generation wireless systems. At the end of 2018, the O-RAN Alliance was opened also for non-service providers to join.
Nokia and China Telecom have signed an agreement to expand the deployment of 4G technology in 19 provinces in China, allowing China Telecom to enhance coverage and capacity as well as the quality of experience for subscribers, while paving the way toward the introduction of 5G technology.
By expanding the radio access network, China Telecom will meet growing subscriber demand with ubiquitous 4G coverage and faster access to the internet and online content, as well as improve access in urban and suburban areas. The agreement with Nokia will also lay the foundation for China Telecom's intended launch of Voice over LTE (VoLTE) services in 2017.
China Telecom's subscriber and traffic growth has been growing rapidly: at the end of June the operator had nearly 207 million mobile subscribers, with 90 million users of 4G devices, an increase of more than 31 million during the first six months of 2016. Last year the company saw 4G traffic increase by more than six times, and it is predicted to account for more than 90 percent of mobile data traffic on the network by 2017.
Nokia is deploying its 4G technology in 19 provinces in China: Shanghai, Jiangsu, Shandong, Zhejiang, Hunan, Hubei, Guangxi, Fujian, Jiangxi, Shaanxi, Heilongjiang, Hebei, Henan, Sichuan, Anhui, Liaoning, Guizhou, Xinjiang and Inner Mongolia. Rollout includes Nokia's Flexi MultiRadio 10 Base Stations. Nokia Global Services - including project management, network design and installation - and also Care hardware and software maintenance services will also be provided. Nokia optimization experts will use Nokia NetAct(TM) to maximize the performance of the network for subscribers.
Mike Wang, head of Nokia Networks China and ASB joint management team, said: "This agreement with China Telecom builds on our long history of collaboration. Our deep-rooted knowledge of the Chinese market will enable China Telecom to meet the demands of an ever-growing and dynamic 4G subscriber base."
