Nokia and AT&T run successful trial of the RAN Intelligent Controller over commercial 5G

  • AT&T and Nokia are co-creating the Radio Access Network (RAN) Intelligent Controller (RIC) based on O-RAN architecture and publishing in open source
  • The limited live trial was performed over AT&T’s commercial 5G mmWave network in New York City
  • In the trial, the RIC ran at the network edge on an Akraino-based Open Cloud Platform

18 June 2020

Espoo, Finland – Nokia and AT&T today announced a successful limited live trial of the RAN Intelligent Controller (RIC) over AT&T’s commercial 5G mmWave network in New York City. Once fully implemented into the network, the RIC platform will enable increased network optimization capabilities through policy-guided, closed loop automation. 

Last year, AT&T and Nokia announced their collaboration to co-develop the RIC software platform, in alignment with the O-RAN Alliance target architecture, to accelerate the creation of open source software for the 5G RAN. The intent is to create open interfaces and an open ecosystem of interoperable components that will enable rapid, flexible service deployments and programmability within the RAN. The RIC software is available at the O-RAN Software Community.

For the recent trial, AT&T and Nokia ran a series of external applications, called “xApps,” at the edge of AT&T’s live 5G mmWave network on an Akraino-based Open Cloud Platform. The xApps used in the trial were designed to improve spectrum efficiency, as well as offer geographical and use case-based customization and rapid feature onboarding.

Ultimately, the trial achieved its test goals. Both companies tested the RAN E2 interface and xApp management and control, collected live network data using the Measurement Campaign xApp, the neighbor relation management using Automated Neighbor Relation (ANR) xApp, and tested RAN control via the Admission Control xApp – all with zero interruption to the live commercial network.

Mazin Gilbert, VP of Technology and Innovation at AT&T, said: “This successful trial is a testament to what we can achieve through openness and collaboration. Together with the O-RAN Alliance, AT&T and Nokia will continue to develop and contribute to the E2 interface and the RIC platform to help enable an intelligent and flexible 5G network.”

Michael Clever, Head of Edge Cloud Platforms at Nokia, said: “We are excited about the success achieved by the joint AT&T and Nokia team in proving out the RIC over AT&T's 5G network in such a great city. This represents a major milestone toward the advancement of RAN network intelligence, openness and programmability, with the ultimate goal of improving wireless networks efficiency and end user experience.”

Fingerprint Cards AB (publ) communicates view on long-term development of markets for biometrics and the company’s competitive position24.9.2020 14:30:00 CESTPress release

Over 80 percent of all smartphones sold currently have some form of biometric sensor. The technology is generally accepted and appreciated by users throughout the world, who use their biometric data to unlock devices, make payments and gain access to apps. There is still growth potential in the mobile industry, in part by increasing the attach rate of biometric sensors for smartphones and in part through new product innovations. However, Fingerprints expects the growth in biometrics to primarily occur in new areas. While the adoption of biometrics in areas outside of smartphones has been sporadic over the past few years, there are now clear indications that biometrics is on the verge of entering into several new consumer mass markets. Fingerprints would therefore like to communicate the company’s view on the long-term potential in key market segments, as well as our aspirations. Market potential in 2026 and beyond Mobile and PC For capacitive fingerprint sensors for smartphones, we see

Företagsakuten förlängs till 31 december 2020 Regeringen har beslutat att förlänga Företagsakuten. Företagsakuten är ett kreditgarantiprogram som infördes för att dämpa de ekonomiska skadeverkningarna av coronakrisen. Utformningen av garantiprogrammet är densamma som tidigare och innebär att Riksgälden kan ställa ut kreditgarantier för utlåning till i första hand små och medelstora företag i Sverige som drabbats ekonomiskt av coronaviruset men som för övrigt är livskraftiga. Riksgälden ställer ut garantin till banker och kreditinstitut som i sin tur lånar ut till företagen. Företag kan nu ansöka om lån inom garantiprogrammet fram till den 31 december 2020 genom att vända sig till sin långivare/bank. En lista på anslutna banker och kreditinstitut finns på Riksgäldens webbsida. Staten garanterar upp till 70 procent av lånebeloppet. Fram till och med vecka 38 (18 september) hade 615 lån till ett värde av 2,2 miljarder kronor beviljats inom Företagsakuten. För mer information se Riksgälden
