NTT DOCOMO and NEC onboarding 5G SA core using AWS

By Aiste Kryzanovske March 1, 2022

NTT DOCOMO and NEC Corporation have launched a proof-of-concept (PoC) testing to run NEC’s 5G core network service in a hybrid cloud environment that leverages the Amazon Web Services (AWS) cloud using end-to-end cloud-native network architecture. Through the PoC, DOCOMO, NEC, and AWS expect to prove the viability of cloud-native mobile networks leveraging a public cloud for network function virtualization (NFV). The PoC will validate the energy efficiency and high performance that AWS Graviton2 processors can bring to NEC’s 5GC in the AWS cloud to achieve an energy-performance advantage over comparable solutions. As the first step, 5GC network functions will run in the cloud on AWS infrastructure and corresponding 5GC network functions will reside on DOCOMO’s on-premises infrastructure to verify availability and operational feasibility. The second step will deploy the 5GC network function on AWS Outposts (on Amazon EC2 compute instances powered by Graviton2 processors) on DOCOMO’s premises. AWS…

Docomo and Airbus conduct a high-altitude connectivity trial

By Aiste Kryzanovske November 16, 2021

Airbus and NTT DOCOMO have tested the possibility of supplying future wireless broadband access using the solar-powered Zephyr High Altitude Platform Station (HAPS). The experiment was conducted in August in the United States, when the Zephyr S aircraft flew in the stratosphere for 18 days to assess different capabilities. The Airbus Zephyr S, which is equipped with an onboard radio transmitter, offered a highly flexible data link during its stratospheric flight to mimic future direct-to-device connection. Test data was collected at different altitudes and during various hours of the day and night, with the goal of determining how weather conditions, varied elevation angles and aircraft flight patterns influence connectivity in the stratosphere. Various bandwidths were used in the tests to replicate direct-to-device services from the HAPS to end-users at low, nominal and high capacity. The demonstration proved the practicality and adaptability of the 2GHz spectrum for HAPS-based services,…

NEC Corporation trials a multicore fiber submarine cable

By Aiste Kryzanovske October 5, 2021

NEC Corporation, along with its subsidiary OCC Corporation and Sumitomo Electric Industries, has stated that they have conducted the first testing of an uncoupled 4-core underwater fiber cable and confirmed its transmission performance to fulfill the stringent requirements of global telecommunications networks. International data usage is anticipated to increase by 30-40% by 2026, owing to reasons such as the expansion of 5G mobile data and the necessity to exchange ever more content between data centers located around the world. Submarine networks are using space division multiplexing (SDM) technology to fulfill this need, which increases the number of separate spatial channels to maximize the overall capacity of the system, decrease energy usage and minimize the cost per bit transferred. Multicore fiber is projected to increase the number of parallel optical fiber cores without changing the size and structure of underwater cables, allowing the introduction of second generation of submarine SDM…

Centene partners with AT&T, Connected Nation, Dell Technologies and Intel

By Aiste Kryzanovske September 21, 2021

Centene has partnered with AT&T, Connected Nation, Dell Technologies and Intel to help reduce the digital gap among youngsters by providing foster agencies in Florida and Missouri better access to the Internet. Centene and the other organizations donated over 1,000 computers and 2,200 hotspots under the K-12 Digital Divide Program. The Digital Divide refers to the economic, educational and social disparities that exist between those who have access to the Internet and those who do not. The program, which is hoped will have a positive influence on the general welfare of the youth, was necessary during the pandemic since computers and internet connectivity were essential for routine activities, such as attending school or visiting the doctor. Mylayna Albright, AVP, Corporate Social Responsibility, AT&T, commented: “This program brings together major players in the health and technology industries to ensure foster youth can access important digital resources that address physical,…

AT&T announces Connected Climate Initiative

By Aiste Kryzanovske September 2, 2021

AT&T has established a Connected Climate Initiative (CCI), which aims to bring together partners and academics to further cut carbon emissions. The firm has set an industry-leading goal of reducing greenhouse gas (GHG) emissions by 1 billion metric tons by 2035. A gigaton is equivalent to roughly 15% of US greenhouse gas emissions and nearly 3% of worldwide energy-related emissions, or 1.6 billion flights from Los Angeles to New York. The company intends to convene the brightest minds from leading technology companies, AT&T Business customers, universities, and nonprofits through the newly formed Connected Climate Initiative to identify best practices, develop innovative new products and use cases, and scale the innovations of startup partners building future’s 5G- and other broadband-enabled climate solutions. At the heart of this initiative is a push to persuade business IT firms to use more renewable energy sources, as well as to move more application…

NEC to develop 5G network in the UK

By Aiste Kryzanovske October 27, 2020

NEC Corp., a major Japanese information technology company, has agreed to support the development of the UK’s fifth-generation wireless networks across the country, as reported by the British government. The announcement came after Japan and the United Kingdom signed a bilateral free trade agreement following Brexit. Details of the deal are currently unavailable. Since the UK has banned Huawei from deploying its 5G network and has decided to fully remove Huawei’s equipment altogether by 2027 because of potential security issues, the question of who can intervene to fill the empty space left by the Chinese seller has remained open. While European giants Ericsson and Nokia were obvious choices, other candidates also made an appearance. The UK government asked Japan to help deploy 5G networks in the country back in July. British officials then told colleagues in Tokyo that the Japanese technology companies NEC and Fujitsu could be the…
