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 »

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.

If there’s one thing that is absolutely unmistakable, going into this week’s IBC conference in Amsterdam, it’s the proliferation of Wi-Fi -- a technology that’s also a service, and the industry’s ticket to providing wireless broadband connectivity that simultaneously rivals mobile, and tightens consumer loyalty.
Note: I’m not the cheerleader type, and as such don’t use the word “bonanza” loosely. By definition it is “a situation or event that creates a sudden increase in wealth, good fortune, or profits.” That fits. Let’s go literal about the increase in wealth, good fortune, or profits. Here’s an impressive supporting number for you: As of this moment, we’ve shipped Read More »

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.

Think about what is going on in the APJC Mobile Market for a minute:
- In Korea, mobile data traffic on 2G, 3G, and 4G networks increased approximately 70% between 3Q 2012 and 3Q 2013.
- In China, mobile data traffic of China’s top 3 mobile operators grew 90% in 2012 and 72% from mid-2012 to mid-2013.
- In Japan, mobile data traffic grew 92% in 2012 and 66% from 3Q 2012 to 3Q 2013, according to Japan’s Ministry of Internal Affairs and Communications
- While in India, Bharti Airtel reported mobile data traffic growth of 112% between 3Q 2012 and 3Q 2013 and Reliance Communications reported mobile data traffic growth of 116% between 3Q 2012 and 3Q 2013.
