Wi-Fi is the glue that brings connected experiences together in our homes—-from streaming video to online gaming, browsing the Web, and more. It’s the foundation for tomorrow’s entertainment too. But, how will it scale to new experiences like 4K, multiscreen HD, and fiber Internet speeds? How can we ensure that it’s reliable when so many new services depend on it to work perfectly, everywhere, all the time?
Our CPE CTO Charles Cheevers, reviews these topics and more. Check out his videos, below:
And we’re off… SCTE began yesterday and our end-to-end cable portfolio is at the center of this year’s conference, which has attracted more than 10,000 attendees to Denver this week.
We have several unique experiences on display—from new IP network solutions to our Wi-Fi Connected Home portfolio, network DVRs, D3.1 solutions and HEVC/ Ultra HD set-tops.
Check out some of our pictures below, but for the best view, be sure to stop by our booth this week (#1764)!

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.
This week at SCTE, everyone’s talking about the future of cable. But in the closing keynote of WICT’s (Women in Cable Telecommunications) “Tech It Out” Conference on Tuesday, our CEO Bob Stanzione will speak about one related topic that often goes unrecognized in that conversation: tomorrow’s engineers.
Tech It Out is about fostering leadership among women in technology, and this charter resonates with Bob’s belief that we have an obligation to inspire tomorrow’s engineers. To paraphrase his words, “We have a responsibility to foster a diversity of thought, starting with children and students—they’ll be engineering our future, so it’s vital that they represent the best that we have to offer.”
But, as Bob will point out, that isn’t the case in engineering, where women are underrepresented to our disadvantage. In his keynote, he’ll talk about the constricted pipeline of female engineers; cover some of the underlying challenges—like the education system, social paradigms, and media influence; and map out the necessary changes for our industry achieve the diversity it deserves.
As Sandy Howe, our SVP of Global Marketing, outlines here, there are many opportunities for women. On Tuesday, Bob will expand on that topic and talk more about the vital role that women play in inventing the future.

Consumers want TV on any screen. The cornerstone of service providers’ IP video migration is delivering this fully managed multiscreen experience.
Our ARRIS 2014 Consumer Entertainment Index found two-thirds of global consumers are interested in a service that allows them to watch any TV program from any device in any location. Almost half of smartphone owners watch TV on their smartphone for at least a few minutes a week, and nearly two-thirds of tablet owners do the same.
Meeting the challenge of a wide range of bit rates, for varying screen sizes, and varying network conditions requires flexible Adaptive Bit Rate (ABR) protocols. However, ABR protocols introduce their own challenges, including breaking the bandwidth capacity bank by requiring a unique stream per screen.
Multicast-assisted ABR has become the solution of choice to manage IP video scalability. To better understand the need and issues around implementing this solution, ARRIS analyzed live viewing behavior across more than 100,000 set-tops for intervals of more than a month. This allowed us to accurately quantify viewership and multicast gains. With this knowledge, we informed a model that allows operators to accurately deploy multicast-assisted ABR.
Our research led to the discovery of potentially significant issues around channel change behavior. In my SCTE paper and during Wednesday’s 9:30 a.m. panel on “Multicast & Unicast: The Best of Both Worlds to Enable Multiscreen Video,” I’ll discuss several mechanisms for mitigating the channel challenge issue.
I’ll also touch on the significant bandwidth capacity benefits of Multicast-assisted ABR, but noting the challenges around channel change events when implementing such a solution. And most importantly, I’ll highlight how these can be addressed for true IP video migration to be successful.
I hope you’ll join me at Wednesday’s session, and I look forward to seeing you in Denver!
Cable operators began using RF over Glass (RFoG) ten years ago to expand their HFC networks with FTTH offerings. The primary challenge for RFoG is what is called Optical Beat Interference (OBI)—a chronic performance issue caused by multiple modems communicating at the same time over the same fiber.
OBI has plagued fiber deployments and prevented mass rollouts for the past decade, because it created unpredictable performance, which worsened as providers added more upstream bandwidth to their networks. Despite several attempts to mitigate the problem, OBI persisted, rendering fiber upgrades costly, inefficient and non-scalable. The advent of DOCSIS 3.1 exacerbated the situation, increasing upstream which magnified OBI.
Today, ARRIS unveils AgileMax™, the industry’s only FTTP, RFoG solution that completely eliminates OBI. The ARRIS AgileMax engine supports split ratios, reaches, and data rates that were previously unachievable, while being completely transparent to xPON solutions. While this alone puts AgileMax in class by itself, it’s further differentiated as CMTS, ONU, and cable modem agnostic—making it the most cost-effective and operationally efficient solution available.
Here’s what John Caezza, President of ARRIS Access Technologies business had to say about it: “We weren’t satisfied with the temporary and operationally complex OBI solutions on the market, so we set out to develop a complete yet simple solution that operators could use to make a seamless transition to DOCSIS 3.1 and PON. ARRIS AgileMax not only delivers on all of those promises, but exceeds the performance of all other RFoG solutions.”
To learn more, stop by SCTE Booth #1764 this Tuesday through Thursday. The ARRIS team would love to answer your questions about AgileMax and talk with you about the company’s complete DOCSIS 3.1 solution, including an industry-leading CMTS/CCAP family.
