Up, up and away! Cloud a Major Topic at IBC 2014

IBC 2014, the conference and exhibition hosted by the beautiful city of Amsterdam, in the generous confines of the RAI facility, came to a close last week. The exhibition, spread across 14 halls and spanning 5 days, attracted more than 55,000 attendees to see the latest offerings and technological advances of over 1500 exhibitors. It’s an exciting place to be… there is a tangible buzz generated from the proximity of so many industry experts and enthusiasts, from veteran business leaders to smart start-up engineers.

My overwhelming take-away from the event was of the continued pervasiveness of the cloud and the cloud services ecosystem. Media management in the cloud, transcoding in the cloud, metadata in the cloud, playout in the cloud, archive to the cloud, cloud DVR, cloud UI rendering, cloud collaborative editing and post-production… and more. The barrier to entry for service providers to launch new, cost-effective, value-add features has never been lower, leveraging the scalability, reliability and efficiency gains that cloud computing together with the SaaS model enables. The movement from hardware to software services is also a driving force behind a slower but inevitable transition, that is, the adoption of IP for the end-to-end video signal path from camera to cutting room to consumer.

The Shift to Content Delivery Networks (CDNs) Supports More and Better Customer Video Experiences

The Internet has emerged as one of the most powerful ways for businesses and consumers to communicate and learn. Its global reach, accessibility and speed have opened doors to areas of knowledge that in the past were available only to a privileged few. With the emergence of popular video-streaming services that deliver Internet video to the TV and other devices, content delivery networks (CDNs) have prevailed as a dominant method to deliver such content. However, the popularity of video and other IP-based multimedia is causing increased traffic for CDNs.

As consumers continue to demand greater amounts of high-quality content over the Internet, service providers (SPs) are finding it difficult to increase revenues while operating efficiently and containing costs. This is due mainly to two things: Read More »

LTE-U By Any Other Name is Licensed-Assisted

I recently read the rather interesting announcement from NTT DoCoMo where they demonstrated LTE running over the unlicensed 5GHz band.  They report a 60% increase in spectral efficiency over IEEE 802.11n Wi-Fi.  The article also noticed that LTE-U is now referred to as Licensed-Assisted Access using LTE or LAA-LTE.  This caused me to pause, and think about several things.

The comparison between LAA-LTE and Wi-Fi is not (and should not be) about spectral efficiency. Rather it is about several other factors:

  • A robust network with a diverse client ecosystem (does anybody reading this blog own an IP device without Wi-Fi? How many of those devices contain LTE? How many are Wi-Fi only, without any SIM card?)
  • The ability to support neutral host deployments (are stadium owners willing to deploy LAA-LTE if it only supports one operator?)
  • The ability to co-exist in a multi-operator environment (how would LAA-LTE operate in dense environments when it has to co-exist with LAA-LTE APs from other operators?)
  • The ability to co-exist in a multi-technology environment (would if it adversely affects the existing and extensive deployments of Wi-Fi infrastructure?)
  • A number of Mobile operators have agreements with Wi-Fi providers for offloading cellular traffic (how does one enable such a scenario with LAA-LTE?)

And if you really want to talk about speeds and feeds, it’s interesting that the test was done against 802.11n, when 802.11ac is now widely available, providing speeds that exceed LTE-Advanced speeds of 1 Gbps (IEEE 802.11 ac Wave 1 provides maximum speed of 1.3 Gbps and Wave 2 provides maximum speed of 3.5 Gbps).  It’s also important to note that LAA-LTE has not been defined yet and so it’s very likely that the LAA-LTE implementation tested here does not have the politeness mechanisms required in certain regulatory domains like Europe. These mechanisms allow fair usage of the unlicensed spectrum by allowing other users an opportunity to transmit and share the spectrum.  These mechanisms already integrated into Wi-Fi will add additional overhead to LAA-LTE that will reduce its spectral efficiency, a factor that needs to be taken into account in any comparison.

IP Traffic Will Need a Fast Lane for Video in 2018

Over the past two decades, Internet Protocol (IP) traffic has been on the rise and is anticipated to continue along a similar trajectory over the next five years. The increasing number of fixed and wireless devices and M2M nodes that are connecting to global IP networks is one of the primary contributors to global IP traffic growth. According to the Cisco’s Visual Networking Index™ Global Forecast and Service Adoption for 2013 to 2018, global IP traffic will increase nearly three-fold over the next five years. The growing number of Internet users and faster broadband speeds are also contributing to this traffic growth. However, another trend likely to increase global IP traffic is the increased use of video applications — online video streaming, live video feeds and video on demand (VoD), as well as various forms of video communications.

The Growth of IP Video

The world will reach 2.5 trillion Internet video minutes per month by 2018. That is nearly Read More »
