technologies & the impact on devices and applications Research reports on Broadband Traffic Management, Mobile VoIP,

Broadband Business Models, Femtocells, IMS

Probably coined the term Mobile data offload in 2008

Coined the term Under the floor player in 2009 Coined the term Happy pipe in 2010

Coined the term Telcowash in 2011

LTE is being deployed..

LTE challenges

Unclear business model

Policy management & charging challenges Unclear when full LTE coverage might be achieved

Too many spectrum bands 2600, 2300, 2100, 1900, 1800, 1700, 900,, ,

Increases component size, cost & power needs

Some auctions delayed anyway

Indoor coverage poor at >2GHz

Roaming nightmare (but does it matter?) Voice and SMS uncertainties

Massmarket handsets a long way off

Is LTE for dumb pipes, or happy pipers?


Should telcos be more scared of under-the-floor players

than over-the-top?

IMS: dead, but now nailed to the perch of LTE?(With apologies to Monty Python)


Mobile IMSFjords, aka RCS

Most likely outcome for LTE VoiceSolution 2011-2012 2013-2014 2015 onwards Notes

VoLTE Some trials. Many

problems found

Patchy rollout, more

in 700-900MHznetworks

Slow growth but not

universal. Used forroaming

If it works, OK for

basic telephony, notfor Voice 2.0

CSFB Few rollouts. Likelynot good userexperience

May be fixed, but notlikely

Fades out asmainstream option

Political choice byGSMA / 3GPP

VoLGA Unlikely to be used,maybe OTT

May come back ifother solutions asbad as feared

Good option forthose with long CSlegacy ahead

Could be revisited by3GPP under anothername

No operator voice.User picks 3rd pty

Used on laptops &tablets. Somesmartphone use

Common on LTEwholesale networks

May be 2nd voiceservice along withoperators own

Some operators willtake fixed bbandapproach

Optimised 3rd-partyVoIP

A few renegadeoperators

Depends on Skype,Google etc

Important in specificpockets but notuniversal

Could be providedfrom other telco aswholesale

Dual-radio Velcro Use for SVLTE inCDMA 1x + LTE

Replacement forCSFB in 3GPP?

Probably superseded Battery impact butbetter overall QoE
