A new approach to upgrading optical networking at the edge

3 March 2020 Sponsors: Huawei

In a world of 5G wireless networks and 400G Ethernet connections, it is easy to forget that other technologies can deliver significant benefits for users. Various technologies can drive enhanced services for carriers and their customers, thanks to some recent innovations. While the optical transport network (OTN) has been in the backbone of many carrier […]

Delivering on the Promise of Open RAN

13 February 2020 Sponsors: ECI Telecom

Open RAN promises many things; disaggregation, virtualization, a wider ecosystem, less reliance on a small number of suppliers, multivendor interoperability, a greater role for white box systems, more cost effective and scalable solutions, faster time to deployment and integration opportunities with edge computing. In time, many of these will be delivered but there is still […]

Carving Up the 5G RAN

13 January 2020 Sponsors: ECI Telecom

The migration to 5G is critical for carriers who are also moving towards cloud RANs and wanting, where possible, to move to open solutions. 5G will bring higher bandwidths, lower latencies, new radio technologies and a new wireless core. RAN disaggregation enabled by cloud RANs and open interfaces gives carriers the opportunity to benefit from […]

5G Changes the Game

28 Nov 2019 Sponsors: ECI Telecom

5G is rolling out faster than previous wireless generations and will have a much bigger impact on telecoms infrastructure and the supply chain. As mentioned in my previous post, 5G introduces a new radio specification (5G NR), a next generation wireless core network (NGC) and a modular RAN architecture that directly supports disaggregation and open solutions. […]

Opening Up 5G RAN Development

31 Oct 2019 Sponsors: ECI Telecom

Behind the headline grabbing transition from 4G to 5G wireless networks there is a significant shift in the radio access network (RAN) from a centralised architecture to a virtualized/cloud (vRAN) architecture. This shift in architecture enables the opening up of the RAN and associated infrastructure solutions, including xHaul networks and edge computing, through public and […]

Supersizing the C-Band

Tuesday, 21 May 2019 Sponsors: Huawei

Over the past seven years the optical transport industry has made huge strides in increasing the capacity of a single fiber using the C-band. The combination of higher order modulation, flex grid channel spacing, higher symbol rates and super channels has increased the spectral efficiency to deliver 32 Tbit/s per single fiber using the standard […]

Optical Networks for the Next Decade

Tuesday, 19 March 2019 Sponsors: ON2020

The volume of user traffic on carrier networks is growing at between 20% and 40% per year and if this trend continues as expected then optical transport networks will become overstretched without a significant increase in capacity beyond that currently planned by operators. The solution to this problem is likely to include a mix of […]

New Open Workgroup to Accelerate Edge Computing

Thursday, 3 January 2019 Sponsors: Netronome

Edge computing, artificial intelligence, machine learning and security are all applications that are important for cloud and networking service providers and can benefit from domain-specific accelerators. Domain-specific accelerators are silicon-on-chip (SoC) devices that are optimized to deliver cost-effective acceleration of specific applications and networking functions. The Open Domain-Specific Accelerator (ODSA) Workgroup is an industry initiative […]
