Everyone wants broadband: end-users want access to the latest entertainment service providers want to provide attractive and competitive service offers governments want to realize socio-economic benefits with e-health and e-learning Access to broadband is not enough – you need high speeds to support all these applications. You need ultra-broadband. Australia was on of the first countries to define a national broadband plan, setting ultra-broadband targets. Governments around the world have followed Australia’s example, and have defined their own broadband plans EU Digital Agenda Connecting America in USA New Zealand Ultra-Fast Broadband (UFB) + Rural Broadband Initiative (RBI) Broadband China Strategic Plan, announced this summer India National Broadband planAs Alcatel-Lucent, we’re involved in the largest and most advanced ultra-broadband roll-outsI want to share some of our experiences with you , and show how service providers and governments around the world are planning to meet those broadband targets[NOTE: the colors on the map represent broadband (ADSL or better) availability today. Lighter = better.]
A few years ago, technology options for ultra-broadband were limited ADSL was widely deployed, but only delivered around 10Mbps Many operators upgraded their DSL network to VDSL2, delivering 20 to 40 Mbps – because it’s relatively quick to deploy and allowed them to compete with cable But if you were looking at ultra-broadband speeds, 100Mbps or more, optical fiber was really your only option – easily delivering 100Mbps or 1Gbps
However, technology has evolved. VDSL2 Vectoring is a new technology that boosts DSL speeds – delivering 100Mbps over an existing telephone line Vectoring is an amazing technology It works by removing the interference or noise on a VDSL2 line just like noise-cancellation headphones And it won’t doesn’t stop with VDSL2 vectoringWe continue to innovateBy the way, when I say “we continue to innovate”, I mean that quite literally.Alcatel-Lucent was first with ADSL and VDSL. We built the first large-scale GPON networks. We were first with VectoringNow we’re working on G.fast, which will still take a few years but could deliver speeds of 1Gbps over very short distances. And we’ve already shown that you can combine G.fast with Vectoring
These new technologies provide more fixed ultra-broadband deployment optionsNot only can you deploy fiber all the way to the homeYou can also bring fiber to any convenient location close to the end-user, and from there, use Vectoring to deliver ultra-broadband speeds over the existing telephone lines The advantage of this approach is that you don’t have to dig up every street, every front yard, or go into every home It’s not just about FTTNode (cabinets), but also FTTBuilding, FTTtelephonepole, etc. – you can even deploy fiber to the sewer or manhole.Any location where you can install some equipment, and connect to the telephone lines will work Having all these options – from FTTH to FTTN, and anything in between- means that for every city, street, or user, you can select the best technology and deployment model, to deliver ultra-broadband in the quickest and most cost effective way As a result, you can connect more people, quicker, and that’s really what it’s all abou
- So how do you select the right combination of technologies and deployment models for your network?It depends on a number of factors:The closer you deploy fiber to the end-user, the higher the bandwidthFTTx deployments with Vectoring are typically more cost-effective (e.g. FTTN investment can be 3x lower than FTTN)Vectoring is also quicker to deploy (e.g. FTTH can take 4x longer than FTTN). And this is very important, because 1) nobody wants to wait for their ultra-broadband connection (we all want it today)2) as a service provider, you can also start generating revenue sooner – and that revenue can be used to connect more peopleObviously, it also depends a lot on local conditionsIf you can use available ducts or aerial fiber, that makes FTTH cheaperIn areas where you have existing copper infrastructure (or existing DSL cabinets), FTTx with Vectoring makes a lot of senseHourly wages can have a big impact on the cost of digging and installationAnd of course… any investment in fiber (as part of your FTTx roll-out) can later be re-used for FTTH.
Because of its low cost, quick roll-out, and high bandwidth, Vectoring has caught the interest of service providers all around the worldWe see interest not just from operators with VDSL deployments (for whom Vectoring provides an easy upgrade to ultra-broadband)But also from operators with fiber deployments, who are looking to complement their FTTH roll-out with FTTx, to speed up their roll-out and make it more cost-effective.This map shows the more than 55 trials we’ve successfully concluded all around the world. All of them confirm that Vectoring delivers on its promise.And believe me – these are no easy testsTypically, an operator will dig up the ugliest and worst piece of copper cable he can findAnd make us prove that vectoring worksThe good news is – it really works as advertizedAnd we see consistently good results. Even on bad cables.We also signed up 17 customers… … who already deployed more than 2.4M vectoring lines More importantly, we also shipped enough vectoring processors to vector 2.6M linesWhy is this important? installing the vectoring processor is the last step before activation so this number shows that service providers are very close to start offering vectoring servicesWe expect that the first commercial vectoring services will be launched in the next few months
Since Vectoring became available (in December 2011), many service providers have embraced mixed deployments, in which they combine FTTH with Vectoring to deliver ultra-broadband services to more people, in a more rapid and cost-effective way. This chart shows an overview of deployment models used by selected operators, about 18 months ago. Back then, we clearly saw two distinct strategies or religionsOne group of customers (about 190 of them) was deploying fiber-to-the-homeAnother group of our customers (about 90) was deploying FTTN with VDSL2 – mostly because they needed to deploy quickly to counter cable competition
Now look at the situation todayIt’s clear that many operators have embraced a mixed approach. Everyone has FTTH as the end-goal But it simply makes sense to complement an FTTH roll-out with FTTx and Vectoring to achieve faster Time-to-Market, and he fastest ROI
So, what next for Australia?The first point is that Australia’s approach has always been visionary. One of the first countries to define a national broadband plan, setting ultra-broadband targets.The second point is that Australia’s NBN has always been a network of multiple access platforms: satellite, fixed wireless and, FTTP for the large majority.I know that the deployment model is now under review to include additional platforms using copper infrastructure.As you can see from my previous comments, this change and flexibility brings Australia more into line with global operator trends.If the objective is to get more broadband to more people more quickly, this is the right way to go.There are many variables but there are also an increasing number of technical solutions and flexible options.It is actually more a matter of economics than technology.KEY LINE: As I have said, Australia’s NBN has always been one of the most visionary, it now has the chance to be one of the smartest broadband rollouts in the world. This is a unique opportunity.I would say, that the important thing is to get the review right and Alcatel-Lucent is ready to help however we can.It is also important that the review be done efficiently and that momentum in the market not be lost.Therefore I welcome news that NBN Co will work with Alcatel-Lucent on a trial of FTTB using vectoring starting soon.
Delivering Ultra-broadband to everyone is the goal. FTTH deployment have started everywhere, but they take time But technology continues to evolve, and new ultra-broadband technologies like VDSL2 Vectoring are now available Service providers around the world are combining FTTH with FTTx to accelerate deployments and make them more cost-effective In the end, that allows them to connect more people, quicker – to get to fast, faster - and that’s what it’s all about
