The Quest to Send 4K Video over Wi-Fi

24 Sep 2014

Charles Cheevers, CTO, CPE business at ARRIS

Almost daily, we see new evidence that people are video junkies-watching, posting, and downloading more video to more devices. Yet, we commonly expect our home Wi-Fi network to carry these experiences seamlessly.

Our ARRIS Consumer Entertainment Index found that almost two-thirds of us have problems streaming or downloading video. Whether it’s a slow connection, streaming delays or a frozen or blank screen—these issues can be maddening.

Wi-Fi can barely handle MPEG-4 video bandwidth, so how are we going to support 4K video transmission over the coming years?

At this year's SCTE, I hope to shed some light on that solution. I'm outlining my thoughts on various technologies and directions being considered to ensure that the Wi-Fi network has both the ability and quality of service to provide a reliable solution. I'll also cover ways we can pre-empt the congestion at 5GHz and show how software-oriented solutions can help facilitate the kind of quality we need to get new pay-TV video services over Wi-Fi.

Specifically, I’ll review the following key areas surrounding this topic:

  • 5GHz spectrum map and what happens when devices try and carve out some deterministic throughput rates;
  • Types of services and devices competing for this airtime;
  • Challenges and main goals ahead for the IEEE High Efficiency Task Force as it tries to create new wireless protocols to handle Gigabit Wi-Fi solutions in the home;
  • Convergence of LTE and Wi-Fi ;
  • Role of network managed Wi-Fi resources and airtime;
  • Emerging ideas around SDN, and SON-based assists to improving Wi-Fi performance.

I previewed this topic on SCTE's site, but welcome you to join me and Comcast at Thursday's 12:45 p.m. "Wi-Fi: The Quest for Quality" discussion. Look forward to seeing you at SCTE.
