Managing Noise and Maximizing xDSL and IPTV Quality of Experience

DSL services are more sensitive to interference than traditional phone services. High frequency (or wideband) noise can cause IPTV to tile or freeze and web access to be slow or intermittent. These situations require effective noise source mitigation. To detect wideband noise, and meet performance expectations, appropriate measuring techniques must be used. Also, with recent advancements in xDSL technologies, including bonding and VDSL2 vectoring, getting a full picture of today’s FTTx and hybrid networks is much needed.

In this webinar, you will learn:
- The effects of noise on DSL service performances
- Best practices for copper pair qualification and VDSL2 performance validation
- How to detect and locate common noise sources on VDSL2 and ADSL services

  • Why C-RAN deployments will give you more headaches than D-RAN Recorded: May 9 2017 33 mins
    Jean-Sébastien Tassé, Product Manager, EXFO
    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!

  • Developing 5G: Rough waters ahead! Recorded: Nov 2 2016 63 mins
    Uday Parida, Product Manager, EXFO
    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

  • Enabling Closed Loop Assurance through Real Time Analytics Recorded: Sep 29 2016 42 mins
    Jose Anes Product Manager - Analytics, EXFO
    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.

  • TESTING THE INTERNET OF THINGS Recorded: Jul 14 2016 62 mins
    Nisar Sanadi, Product Manager, EXFO
    To date, the buzz about the Internet of Things (IoT) has been more talk than walk. Promises—or warnings, depending on one’s point of view—of up to 30 billion devices by 2020 have been floating around for a while, yet hardly any progress has been made towards it.

    But that could all be about to change.

    From the perspective of mobile network operators (MNOs) and network equipment manufacturers (NEMs), the main roadblock had been the lack of IoT standards from 3GPP. While 3GPP has taken baby steps to address the IoT since Release 10 (R10) in 2011, there hasn’t been a comprehensive set of specifications—until now!

    Join the EXFO webinar to learn more about:
    - The NarrowBand IoT (NB-IoT) specification, ratified as part of Release 13 (R13) in June 2016
    - The impacts on 3GPP networks of NB-IoT and other 3GPP specifications related to the IoT
    - The new testing challenges associated with the IoT, and how EXFO’s simulator product line can address them
