Nokia Hits 428 Mbps w TD-LTE with 3-Band CA and 256QAM

Nokia Networks, together with SK Telecom, demonstrated 428 Mbps data transmission using TD-LTE 3xCA with 256 QAM.

The test used a Qualcomm  Snapdragon X12 LTE modem along with Nokia's Flexi Multiradio 10 Base Station and software to aggregate three carriers on the TD-LTE band 41 spectrum (2496 – 2690 MHz).

The companies said this lays the foundation for the introduction of TD-LTE in Korea, with Nokia’s Single RAN Advanced platform as a foundation for SK Telecom.

• In November, Nokia Networks has achieved a transmission speed of 19.1 Gbps and lower latency using 5G cmWave technology in a trial in South Korea. 

• The trial used an OFDMA-based TDD system with 4x100 MHz carriers and 8x8 Multiple-Input Multiple-Output (MIMO), enabling eight independent data streams sent between the base station and the user device. In addition, 256QAM modulation enables the sending of eight bits of information per modulation symbol. The scaled OFDM has a shorter symbol length and Transmit Time Interval (TTI) that is expected to achieve a lower latency than with LTE.

Facebook Shows GPU-based System for AI

Facebook will open source its design for a GPU-based system optimized for machine learning (ML) and artificial intelligence (AI).

The hardware system, code-named "Big Sur", was developed by Facebook's engineering team to run its software capable of answering questions based on ingested stories and articles. Big Sur is Open Rack-compatible and incorporates eight high-performance GPUs of up to 300 watts each, with the flexibility to configure between multiple PCI-e topologies. It uses NVIDIA's Tesla Accelerated Computing Platform.

Facebook said its plan to open-source Big Sur and will submit the design materials to the Open Compute Project (OCP).

O3B Lands $460 Million to Expand Global Satellite Constellation

O3b Networks closed $460 million in incremental financing to support its next-generation satellite network.  The company plans to use the money to expand the total number of satellites in its constellation from twelve to twenty.

O3b began full commercial operations in September 2014. The company said it now supports connectivity for more than 40 customers worldwide, with more than 50% of those customers having already upgraded their service commitments to O3b during the first year of commercial operation.

“This is an incredibly exciting time for O3b and its customers. Our constellation is highly scalable and can be grown in direct response to market demand. In only a little over a year from our full commercial launch, we can already see the need for substantially more capacity in orbit to serve our customers. We are the No.1 operator in the Pacific and, together with Royal Caribbean, we have revolutionized the cruise connectivity market. Our Telco customers are expanding their service offerings and growing their markets on the back of O3b’s performance and capability,” said Steve Collar, CEO of O3b Networks.

Wind River Offers Reference Design for Virtual Business CPE (vBCPE)

Wind River introduced a reference design for a virtual business customer premises equipment (vBCPE), following extensive collaboration with four Network Functions Virtualization (NFV) software partners: Brocade, Check Point, InfoVista and Riverbed.

The vBCPE design, which runs on the Wind River Titanium Server™ NFV infrastructure (NFVI) platform, supports virtual network functions (VNFs) from each of these partners.

"We are grateful to our VNF partners for their collaboration in developing this reference design,” said Charlie Ashton, senior director of business development for networking solutions, Wind River. “Together we have demonstrated that it’s possible to integrate VNFs from multiple sources into a service chain that provides the end-to-end functionality for an enterprise-class vCPE solution, running on an NFVI platform that ensures carrier grade reliability.”

Huawei Outlines Vision for Application-driven Carrier Networks

Huawei outlined its vision for a carrier-grade Application-driven Network (ADN) network architecture.

The idea is to prioritize network applications and service demands in network design, unlike conventional approaches that focus on resource utilization and optimizing network operations.

The company said its ADN will support 5G network slicing and will bolster both near and long-term network evolution. ADNs will differ from existing NFV and SDN concepts, but will integrate NFV and SDN technologies that have not yet delivered any economic benefits into a comprehensive network architecture that focuses on user experience.

Speaking at IEEE Globecom 2015 in San Diego, Huawei Fellow Dr. Wen Tong said: "Our innovative ADN architecture vision puts applications at the network's core to deliver significant efficiency gains for network applications. Unlike traditional network architectures, ADNs will support application abstraction, network reorganization, global and local coordination of network resources, and application decoupling by service layering. With these advantages, ADN is poised to meet a variety of future application demands, for example, in 5G networks."
