2020 “Straw Man”1bn LTE handsetsComms services ARPU $20 / mo[but 50% carried on 2G/3G/WiFi]$120bn revenue= equivalent to 2010 SMS market
Lots of options for voice on LTE networks
LTE network owner
Full IMS + VoLTE
“Velcro” CSFB or
Dual-radio
Data only. BYO-VoIP
Partner Skype / Google
etc
Cloud voice
Partial IMS / NGN VoIP
June 2011
+ need for continuity at LTE / 3G / 2G /WiFi boundary

LTE voice & VoLTE challenges
Too many spectrum bands Acoustics Offload / multi-bearer scenarios Unknown need for optimisation & tuning of RAN High probability of OSS / BSS headaches Lack of clarity around network-sharing / wholesale scenarios Indoor coverage problems, esp. with MIMO Massmarket handsets a long way off Where is SMS???
June 2011
VoLTE only addresses “old telephony”, not general-purpose voice for future apps. Should be called ToLTE

Some technology gaps?
June 2011
Telephony & messaging model for wholesale
LTEnetworks
VoIP and messaging in
complex offload
scenarios
Prioritisation & QoS
engines for complex
scenarios
Signalling management
for VoLTE, comms apps
& MBB
On-device measurement
of user-perceived
QoE
Advanced acoustic
technology optimised for mobile VoIP
Solution for SMS on LTE that works
Dual-radio GSM / LTE devices and
chipsets
