Whats Driving 3G Evolution?Featuring Chris Evarts, Wireless Technology Specialist.

As wireless networks advance, mobile operators look to in-crease the capabilities of their networks with 3G. This sessionhighlights industry advancements that are driving wirelesscarriers to re-architect their networks with R99, R4/R5, LTE,CDMA 2000, and UMB, among others.

Monsho: Whats up? Its Monsho here,with another session o Get Schooled.Are you ready or todays pop quiz?Okay, here we go.

What are some o the applications driv-ing the 3G evolution? Is it: (a) binarycode is just so yesterday, (b) the de-mand or connectivity to in ormationand people, or (c) the new web concerthosted by Kenny G and his backgroundsingers? Get it, 3G?

Dont know the answer? Dont worry. Sit

back and relax. Its time to get schooled.Dave Morfas : Hi, Im Dave Mor as withTellabs, and today Im here with ChrisEvarts, and we are going to talk about 3Gevolution.

Are these sort o evolutionary steps thathave to take place one a ter the other, orare carriers going to jump rom one tothe other as they come out? I mean, is it,you know, a complete linear thing or is itadoption as they see necessary or theirapplications?

Chris Evarts : I think its going to be morethe latter o that, the adoption as theysee necessary or applications.

What weve seen in the industry is, therehave been times where steps have beenskipped going orward, so its not neces-sarily a sequential, you know, lockstepevolution. It takes time to develop thesestandards and to get the standards out.

One example, I think is UMTS. You hadRelease 99, then you had Release 4, you

have Release 5. Now theres Release 6and Release 7. It costs a lot o money todeploy these technologies. What youtend to see are the carriers, the olkswho have to build these networks, havea business case they have to justi y. Theyhave to fnd the economic model that willwork or them.

When theyre looking or that economicmodel, they have to fgure out, Well,how much bandwidth am I going todeploy, how many subscribers am I going

to have to support or each cell site?Things like that. They cant necessarilya ord to buy every single generation othe standards that came out.

And so what youll see is, maybe theylltake a partial step in a technology. I thinkyou can fnd EV-DO. They didnt spendmuch time in the Release 0 o EV-DO;they mostly went straight to Rev. A. Acouple o networks did do small deploy-ments o EV-DO, but Rev. A came along,it was really the solution that was goingto give them the bandwidth that theyneeded. So they started with Rev. 0, orRelease 0, but they didnt spend muchtime on it. They pretty much wentstraight to Rev. A.

I think in North America you could makethe same case or UMTS, where theyreally went to a Release 4, almost Re-lease 5, type o deployment architecture,

or their frst deployment o UMTS. Theyreally completely skipped Release 99.

So I think that sort o begs the questions,

will they actually do every single releaseo UMTS? Will they really do Rev. B,Rev. C? And its a timing thing, and amarket demand. You know, what do theyhave to do to compete with each other?You know, do the UMTS carriers have toget to Release 6 in order to compete withRev. A or UMTS? There are questionslike that.

I dont know the exact answer o what allthosewhich releases will be adoptedand which ones will be skipped. HSDPAis a good example o that. HSDPA wasntreally defned in Release 4. Theyre reallydeploying a Release 4 network with HS-DPA in it, because they need that high-speed download. Does that mean theyllgo straight to Release 5, or will they wait

or Release 6 be ore they go to the nextstep? Because every release they deployis a major investment or them. So theyhave to fgure out where do we get theeconomic beneft?

Dave Morfas : One o the things that we

talked about was, in the network thereis quite a bit o cost associated with thebackhaul piece o the network. Theresplenty o in ormation out there that sug-gests that its quarter o total OpEx or awireless operator.

So what are operators doing and/or whatis Tellabs doing to help operators opti-mize that cost?

Chris Evarts : Sure, that is a huge issueor wireless carriers. And its really an

issue o scale.

The reason that carriers have such ahuge percentage o their operating costsgoing towards these backhaul networksis because they have so many cell sites,because they have such a large popula-tion to cover. In North America and evenin some o the European countries, Iknow that the number o cell sites thattheyre supporting ranges rom 20,000cell sites up to 50,000-plus cell sites.

Whenever you start doing the mathe-matics behind that and say, Okay, I haveto deliver 3 megabits o bandwidth toa cell site and its going to cost me, youknow, $200 a month, $600 a month todeliver that bandwidth to that cell site,then you have to multiply that number by50,000 times, times 12 months, and allo a sudden you go, Wow, that is a hugenumber.

One o the areas that weve spokenabout is Ethernet. Ethernet is really atechnology that lowers the cost o largeamounts o bandwidth to transport. So it

moves away rom T1s towards Ethernet.Ethernet allows these carriers to get 10megabits out to a cell site on a singlepipe. It also allows them to expand thatbandwidth essentially via a so twareconfguration rather than having to addanother T1 and another T1.

Another area where Tellabs is workingwith carriers is in rearchitecting thatbackhaul network. Now that were reallymoving to a more data centric architec-ture, we can actually put aggregation

points urther out into the network tocollect tra fc closer to the cell sites, andwhen we aggregate that tra fc, we canshare bandwidth between di erent cellsites, and that sharing o bandwidth ac-tually helps the carriers lower their coststo deliver that transport. So thats an areawhere Tellabs is doing a lot o work withcustomers, really at evolving this network

rom a TDM architecture to a true packetarchitecture, leveraging strength likeEthernet.

Dave Morfas : I think in the end, then, theonly concept that we see, whether itsLTE or whatever technology is behind it,however these networks evolve, there isgoing to be change, there is going to be

evolution. There are going to be applica-tionssome that we know, some that wedont know at this pointthat are goingto change these networks.

Chris Evarts : Well, thats a great point.Change is defnitely occurring in thewireless networks. You could say that theInternet was invented 30, 40 years ago,but it really went through a huge, explo-sive growth phase in the 90s.

I think were seeing the same thingcome to wireless networks now, where

that data technology is really starting tohit the speeds thats going to make theadoption rate go up, and the networksgoing to undamentally have to change

because o this in ux o bandwidth thatsgoing to have to be supported.

So there is a large change going on.Were going to be going through it. Its anexciting time in wireless networks.

Monsho : That wasnt too hard, was it?The correct answer was (b) the demand

or connectivity to in ormation andpeoplelike a neighborhood block partywithout the chips and dip.

Come on back tomorrow or another popquiz, and maybe a little Kenny G.
