Google to Light 6th Undersea Cable in Which It has Ownership Interest
Google to Light 6th Undersea Cable in Which It has Ownership Interest
Google is working with Facebook, Pacific Light Data Communication and TE Subcom to build the first direct submarine cable system between Los Angeles and Hong Kong. The move highlights changes in the way global wide area network capacity is created and supplied.
The Pacific Light Cable Network (PLCN) will have 12,800 km of fiber and an estimated cable capacity of 120 Tbps, making it the highest-capacity trans-Pacific route, a record currently held by another Google-backed cable system, FASTER.
The project represents the sixth submarine cable in which Google has an ownership stake, joining the ranks of the Unity, SJC, FASTER, MONET and Tannat projects. The new network is expected to be operational in 2018.
Though http://finalevil2009.blogspot.com /2015/03/what-drives-global-bandwidth-demand.html" style="text-decoration: none;">data center traffic is a fraction of end-user traffic or traffic within single data centers, intra-data-center traffic has the fastest growth rate, at about a 32 percent compound annual growth rate.
In addition to http://finalevil2009.blogspot.com /2015/03/cloud-computing-drives-global-bandwidth.html" style="text-decoration: none;">cloud computing and cloud-based apps, video, mobile users and Internet access now drives wide area network capacity demand.
Those apps and functions now drive “in the data center” traffic, long haul and metro traffic growth. In fact, wide area network traffic, though growing robustly, is not growing as fast as “within the metro” demand.
Metro-area traffic likely surpassed long-haul traffic in 2015, and will grow nearly twice as fast as long-haul traffic from 2014 to 2019.
The higher growth in metro networks is due in part to the increasingly significant role of content delivery networks, which bypass long-haul links and deliver traffic to metro and regional backbones.
Content delivery networks will carry over half of Internet traffic by 2019. Globally, 62 percent of all Internet traffic will cross content delivery networks by 2019 globally, up from 39 percent in 2014.
Traffic from wireless and mobile devices will exceed traffic from wired devices by 2019. By 2019, wired devices will account for 33 percent of IP traffic, while Wi-Fi and mobile devices will account for 66 percent of IP traffic. In 2014, wired devices accounted for the majority of IP traffic at 54 percent.
Though there has been a mix of “carrier-purchased” and “enterprise private networking,” the current trend in the WAN market includes a higher mix of “owned” networking by big app providers such as Facebook and Google.

It Has Taken a Couple of Decades but Fixed Wireless is Coming Back in a Big Way
It Has Taken a Couple of Decades but Fixed Wireless is Coming Back in a Big Way
Windstream plans to expand its fixed wireless access operations in 40 U.S. markets, using 39-GHz millimeter wave spectrum, presumably for backhaul and business customer access.
Ironically, Windstream in 2008 wrote down the value of its 39 GHz spectrum holdings to zero, as part of a sale of mobile and wireless assets to AT&T Mobility.
The collapse of a millimeter-wave access services business is not terribly unusual. Whole companies (Windstar and Teligent, for example) went bankrupt after trying to build an enterprise access business using millimeter wave technology, after the passage of the Telecommunications Act of 1996.
But times change. Platforms become more capable. Costs go down. And with coming 5G mobile networks embracing millimeter wave technology, what was a broken business model two decades ago might well become an essential underpinning of next generation networks, both mobile and fixed.
Google Fiber, Facebook, AT&T and Verizon are a few of the leading firms now developing or planning to use fixed wireless in a significant way for Internet access.
Cambridge Broadband Networks (CBNL) is providing the radios and and Straight Path Communications is supplying the spectrum licenses for the Windstream rollout.
The new technology will allow Windstream customers data speeds of up to 275 Mbps full duplex, and it also supplements Windstreams other fixed wireless access technologies that range in speed from 1 Mbps to 1 Gbps.
Windstream will deploy in seven existing markets where it currently offers fixed wireless access technology - Chicago, New York City, Boston, Cleveland, Philadelphia, Milwaukee and Little Rock using equipment from CBNL and spectrum from Straight Path.
Windstream will also deploy CNBL equipment in 33 new markets where it will begin offering its fixed wireless technology. Those markets include Atlanta, Baltimore, Charlotte, Cincinnati, Dallas, Detroit, Kansas City, Miami, Minneapolis,Nashville, Oklahoma City, Phoenix, Richmond, San Antonio, Seattle and St. Louis.
Under the agreement, Windstream has the option of eventually expanding fixed wireless to an additional 32 markets where Straight Path owns 39 GHz spectrum.
