We believe that network sharing is key to do more, effectively and better for the benefit of our clients and all stakeholders, in view of the process of change that will be triggered by the launch of 5G in the years to come and that will be paramount for the development and digitalization of our Country”

Cisco customer wins at MWC: Airtel, KT, Softbank, Sprint

Airtel has selected Cisco to build India's largest 5G-ready, IP-based fully automated network. Airtel's IP-based network architecture will enable new functionality, including segment routing, traffic engineering and ethernet VPN that helps ensure seamless interoperability and the ability to leverage existing investments in its MPLS-TP network.

KT has selected Cisco to transition its network architecture to better manage upcoming 5G traffic with advanced routing and automation software, intelligent analytics and machine learning. Specifically, KT has rolled out a new 5G mobile network platform with automated and virtualized technologies on Mobile Edge Cloud, featuring Mobile Packet Core, network slicing, segment routing, control and user plane separation (Remote-CUPS). The new architecture with Remote-CUPS is designed to serve reliable, scalable, flexible and low-latency network services. The virtualized mobile packet platform is designed to remotely manage traffic at scale and accelerates packet processing to meet the requirements of commercial 5G services with high throughput and low-latency network services.

The end-to-end network includes a 5G routing backbone with Cisco Network Convergence System Router 6000 and ACI on Nexus 9000 switching platform at KT’s distributed data centers.

“As the global leader in 5G, KT is aligned with innovative technology partners like Cisco that can design and launch commercial 5G services focused on ultra-low latency as the world’s first CUPS architecture use in combination with the strong foundation of IP network hardware, software and cloud-powered technologies” said Su-Kil Lee, Senior Vice President of Network Research Technology Support Unit, KT Corp.

SoftBank is deploying Cisco's Segment Routing IPv6 (SRv6) networks nationwide to build a future network architecture. Cisco says current mobile networks are deployed as divided networks, with several layers and complicated control plane processing, which makes it difficult to respond to strict quality requirements like in the case of 5G. Deploying SRv6 in a 5G mobile network simplifies network layers and integrates user plane functions from end-to-end with only IPv6 protocol, making things simple, controllable, and flexible.

Sprint is relying on the Cisco Network Convergence System 540 router series, which is capable of tripling backhaul network capacity and delivering 100G connectivity into the core transport network, and the Cisco Network Services Orchestrator for performance optimization and network automation.

"Cisco NCS routing technology powered by automation software running traffic over dark fiber offers us an ideal blend of innovative technology to support our LTE Advanced and 5G network," said Greg O'Connor, vice president of Network Core and Access, Sprint. "This mix of innovation strengthens our backhaul network and our ability to support connect-to-everything experiences for our customers."

“We’re excited to partner with Verizon to take the next step in SD-WAN. 5G is a transformational technology, and when combined with Cisco SD-WAN, users’ application experience can be better than ever before,” said Scott Harrell, senior vice president and general manager, Enterprise Networking Business, Cisco.“Verizon’s new Mobile SD-WAN will help enterprise customers quickly and easily transition to 5G, giving them an edge as we embrace the next generation of mobile connectivity.”

Rajeev Suri: Nokia can meet demand for European 5G rollouts

It is bluntly not true that if a certain vendor is held back then 5G rollouts in Europe will be delayed and costs will rise, said Rajeev Suri, CEO of Nokia, speaking at a press event ahead of Mobile World Congress in Barcelona.

Taking the example of current 5G rollouts underway in the United States, Suri said that it is illogical to assume that timely 5G rollouts in Europe are dependent on one vendor. Europe is likely to face to 5G rollout constraints from spectrum availability, which will play out over several years.

Suri also stated that Nokia has the technology and industrial capacity to meet whatever commercialization demands that mobile operators require.

Suri went on to give 5 predictions about 5G

1. Security will become (even more) non-negotiable
2. Operators will start to make money from 5G especially from enterprise services
3. 5G will uncork global productivity
4. 5G will grow and grow for the next decade
5. 6G - apart from researchers at Bell Labs and certain politicians, there's no need to talk about 6G when so much is yet to be accomplished in 5G.

Samsung has shipped over 36,000 5G base stations

Samsung Electronics completed the development of its5G mmWave chipsets – comprised of Radio Frequency Integrated Circuits (RFICs) and Digital/Analog Front End (DAFE) Application-specific Integrated Circuits (ASICs) -- supporting 28GHz and 39GHz bands. The company said its chipset design, which is based on 28nm CMOS technology, enables about 25 percent reduction in size, weight and power consumption for 5G base stations when compared to the previous iterations.

Samsung’s new RFICs operate on bandwidths that have been expanded to a maximum 1.4GHz, compared to 800MHz for previous RFICs. The size of RFIC is reduced by 36 percent and overall performance is enhanced by decreasing the noise level and improving the linearity characteristics of the RF power amplifier. Samsung has developed RFIC solutions for 28GHz and 39GHz and plans to commercialize additional RFICs for 24GHz and 47GHz this year, allowing further expansions into markets that will use these higher frequency bands.

Samsung's DAFE ASIC provides analog-to-digital conversions and vice versa. The 5G DAFE manages large bandwidths of many that are hundreds of MHz and developing an ASIC allows for the reduction in size and power consumption of 5G base stations. Without investing in ASICs, the DAFE on its own would be too big and power insufficient to meet the product needs of carriers.

“Our breakthroughs in 5G R&D have been key driving forces behind successful 5G commercial services across the U.S. and Korea in 2018, with over 36,000 5G base station shipments,” said Paul Kyungwhoon Cheun, Executive Vice President and Head of Networks Business at Samsung Electronics. "At the forefront of ushering in the 4th Industrial Revolution, Samsung will continue to accelerate 5G commercialization, ultimately impacting industries and everyday lives by offering low latency, ultra-high speed, and massive connectivity.”

The company also noted that it has shipped over 36,000 5G base stations as of February.

Toshiba develops bridge chip using PAM 4 to boost SSD speed and capacity

Toshiba Memory has developed a bridge chip for connecting flash memory chips into faster and higher capacity SSDs.

In SSDs, multiple flash memory chips are connected to a controller that manages their operation. As more flash memory chips are connected to a controller interface, operating speed degrades, so there are limits to the number of chips that can be connected. In order to increase capacity, it is necessary to increase the number of interfaces, but that results in an enormous number of high-speed signal lines connected to the controller, making it more difficult to implement the wiring on the SSD board.

Toshiba said it has overcome this problem with the development of a bridge chip that connects the controller and flash memory chips (Fig. 1), three novel techniques: a daisy chain connection including the controller and bridge chips in a ring shape; a serial communication using PAM 4; and a jitter improvement technique for eliminating a PLL circuit in the bridge chips. By using these techniques overhead of the bridge chips is reduced, and it is possible to operate a large number of flash memory chips at high speed with only a few high-speed signal lines.

The ring-shape configuration of the bridge chips and the controller reduces the number of transceivers required in the bridge chip from two pairs to one pair, it achieves chip area reduction of the bridge chip. In addition, adopting PAM 4 serial communication between the controller and the daisy-chained bridge chips lowers the operating speed in the bridge chips’ circuits and relaxes their required performance.

The prototype bridge chips were fabricated with 28nm CMOS process, and results were evaluated by connecting four bridge chips and a controller in ring-shape daisy chain.
