  • Why C-RAN deployments will give you more headaches than D-RAN
    Why C-RAN deployments will give you more headaches than D-RAN Jean-Sébastien Tassé, Product Manager, EXFO Recorded: May 9 2017 33 mins
    On the road to 5G, centralized radio access network (C-RAN) architecture is a key stepping stone. C-RAN is the next logical evolution in fiber-to-the-antenna (FTTA) networks, or distributed RAN (D-RAN), and involves centralizing several baseband units (BBUs) in a location away from the towers and antennas, rather than collocating BBUs with the remote radio head (RRH) on the antenna site.

    In this whiteboard video, we will explore 2 specific challenges of C-RAN networks, namely the attenuation issues induced by the long distance between the BBU and the RRH, and the interconnection problems – and finally how to solve them.

    This webinar will conclude with a live Q&A session!
  • Defining Virtualization to Power your Network Transformation
    Defining Virtualization to Power your Network Transformation Yves Gagnon, Product Manager, EXFO Recorded: Apr 26 2017 36 mins
    Virtualization brings with it so many promises, changes and so much uncertainty. Will smarter networks actually deliver? Network transformation is imperative if you’re planning to be part of the massive digital transformation sweeping the industry. However, your transformations can’t negatively impact customers, despite the new level of complexity brought on by the virtualization and abstraction technologies required to meet the explosive demand for new, tailored services.

  • Test your way to NB-IoT success
    Test your way to NB-IoT success Nisar Sanadi, Product Line Manager, EXFO Wireless Core and Uday Parida, Product Manager, EXFO Wireless division Recorded: Apr 20 2017 64 mins
    The ratification of the 3GPP R13 specifications last year was like the firing of a starting pistol, kicking off the race to deploy NB-IoT networks. NEMs are racing against the clock to support the many changes mandated by these specifications. For their part, MNOs are announcing aggressive schedules to launch their NB-IoT networks and time to market pressures are intense. However, quality and reliability cannot be compromised. Ensuring a successful launch under these conditions requires rigorous and comprehensive testing in a time & cost-effective manner. Not only do compliance, functionality and inter-working need to be verified, but also the ability to handle the load and traffic patterns that can be expected in a live network with several million IoT devices.

    This webinar will delve deeply into what it takes to test IoT network elements and networks in order to get them ready for launch. Whether you are interested in conducting end-to-end testing of the network or isolating certain specific elements for testing, such as the eNodeB, MME, SGW or SCEF, for example, you will gain new insights based on our extensive 3GPP technology testing experience.

    Topics that will be covered:
    -Evolution of 3GPP architecture due to IoT
    -Implication of IoT on functionality, performance, capacity aspects of network elements
    -Potential challenges and pitfalls with IoT deployments

    3 main benefits they will get from attending the webinar:
    -A thorough understanding of the impact of IoT on 3GPP networks
    -A deep dive into key testing use cases and KPIs to ensure quality & reliability
    -A proven methodology for successful deployment

    Who should attend:
    -Test Managers
    -Test Engineers
    -Service Deployment Managers
    -Quality Assurance Personnel

  • Developing 5G: Rough waters ahead!
    Developing 5G: Rough waters ahead! Uday Parida, Product Manager, EXFO Recorded: Nov 2 2016 63 mins
    5G continues to generate buzz and grab the attention of many. It will be the platform enabling growth in many industries, ranging from the IT sector to the automotive, entertainment, agriculture and manufacturing industries. Different sectors have different use cases and network requirements. Some require superfast downloads while others require ultra-reliable communication. 5G networks will have to cater to an extremely wide variation in requirements.

    While the official 5G specifications are set to be published in mid-2018, there are already announcements by major network operators about its launch starting as early as next year. The anxiety around 5G, the race to be the first, and the unavailability of global standards could bring about a few challenges at the beginning.

    Join our webinar to learn more about:
    •Various use cases of 5G and their diverse requirements
    •Virtualization as the key enabler in delivering differentiated services
    •The 5G New Radio and the many connectivity options to the core network
    •The new testing challenges associated with the above changes, and how to best address them
  • Enabling Closed Loop Assurance through Real Time Analytics
    Enabling Closed Loop Assurance through Real Time Analytics Jose Anes Product Manager - Analytics, EXFO Recorded: Sep 29 2016 42 mins
    One of the advantages of software-defined networking (SDN) and network functions virtualization (NFV) is the ability to modify the network on the fly. A closed feedback loop between the service assurance solution and the orchestration system enables network self-healing and self-optimization when providing mission critical services. By identifying performance issues we can take immediate action to solve problems or improve service reliability, thus reducing mean time to repair (MTTR).

    You need to ensure that the analysis is performed in real time. Most service assurance solutions set real-time analytics as a goal. Being such a key component of the service assurance solution, further analysis is required on how close to that goal the solution can reach. There are many areas in this type of solution that demand attention: data collection, normalization, correlation, analysis, service-level impact, alerting and more. Each element requires a specific set of strategies to optimize the time taken to make a determination.

    Key questions you need to ask when defining real-time analytics include: How many moving pieces do we have on the service assurance solution? How many different vendors are involved? How many data collection systems? Do you need to transfer that data to a second service quality or service experience analytics solution before deciding you need to request a change from the orchestrator? How does your system scale? How many times do I need to manipulate the data to integrate it across multiple systems? Do you need to aggregate collected data at multiple levels before a decision is made?

    In this webinar, and its associated whitepaper, we go deep into these aspects of how real-time analytics are crucial to enable closed-loop service assurance in your SDN or NFV solution. The webinar will provide you with ideas on how to optimize your service assurance platform.
