Technology to Drive Wireless Disruption, Service Monetization Mired in Uncertainty
Global survey of mobile operators
to get decision-maker insights
Devices continue to drive change
among subscribers & operators
VoLTE is seen as necessary but
not a top priority
Small Cells and Wi-Fi offload
provide a capacity boost
LTE Advanced will bring improved
spectrum efficiency & lower costs
FDD & TDD will both succeed, but
not yet clear how they will coexist
Radisys sponsored this survey,
conducted by Senza Fili

Devices Drive New Usage Models
“New form factors will emerge, but change will continue to be driven by smartphones and tablets,
entering new segments and expanding their functionality.” – European survey participant
Devices will continue changing
the usage model
Smartphone adoption spreading
to feature phone users
Tablets may create a second
wave of traffic increase
Increase adoption of data-centric
devices drives innovation among
operators
Cloud applications will have an
impact on design of devices

Small Cell and Wi-Fi Offload: the Quest for Capacity Density
“Today it is Wi-Fi offload, but in the long-term small cells will become more important to increase
capacity.” – North American survey participant

LTE’s Future: LTE-A, TDD-FDD Networks
“LTE-A will be a gradual & incremental upgrade, with carrier aggregation as its main component. Without it, most
operators without 20MHz channels cannot fully benefit from the new technology.” – North American participant
“Traffic loads are growing so fast that FDD LTE will not be sufficient alone. We will need TD-LTE as well.”
– APAC survey participant
Wired Backhaul
LTE-Advanced (LTE-A) ITU-T’s True 4G… Marketing’s 5G…
3GPP R10
Carrier Aggregation • Aggregate multiple contiguous & non-contiguous carriers up to 100MHz
• Peak data rates 1Gbps

• Over-the-air (OTA) backhaul

‘Donor eNB’ Relay (RN)
SON Essential for HetNets
Centralised • SON solutions where SON algorithms are executed in a centralized entity – say, OAM
• In such solutions SON functionality resides in a small number of locations
• More control for operator (less scalable)
Distributed • SON solutions where SON algorithms are executed at network element (eNB / HeNB)
• In such solutions SON functionality resides in many locations
• Less control for operator (most scalable)
Hybrid • SON solutions where some of the SON algorithms are executed in the OAM system
while others are executed at the network element level
• Best option, most suited for adhoc networks (for femto / small cells)
• Operator can “move” to Distributed option as and when they have more confidence on
multi-vendor SON algorithms
VoLTE: Eventually Needed
“Circuit-switched voice is not going to disappear over the next five years. But we do need VoLTE to
gradually reduce our dependency from legacy 3G and 2G networks.” – APAC survey participant
Voice is still an essential
component and necessary to
LTE’s success
VoLTE needed to decrease
dependency on legacy
networks
Concurrent voice and data
connectivity is a driver to
deploy VoLTE soon
Revenues are largely
unaffected by introduction of
VoLTE
MPX-12000 – VoLTE MRF Video & Voice over LTE
VoLTE Media Resource Function
• High Definition Voice, including AMR-WB
• VQE – critical media conditioning in noisy
wireless environment
Conversational Video
• Video calling – HD video 720p, H.264
• Video conferencing
• Video Transcoding
Audio/Video VAS
• Conferencing, Ringback, Multimedia mail…
Open 40G ATCA Platform
"Mavenir has already integrated the Radisys CMS-9000 media server with our mOne Convergence
Platform for one of our LTE operator deployments…. Products like the MPX-12000 – with a design
objective to increase MRF media processing capacities for mobile video services – offers an enticing
MRF product evolution for LTE operators"
– Terry McCabe, CTO, Mavenir Systems
A Conspicuous Absence: Service Creation and Monetization
Drivers related to new
services & monetization
did not make it the top six
drivers: Why?
Path to revenues not as
clear as the technology
and device path
Many opportunities,
unclear strategy
“We cannot afford to manage traffic growth without a corresponding increase in revenues. We have
ways to increase capacity, but we cannot necessarily afford it.” – European operator

“Counting packets is not the way to make money.” – North American operator

Taking Charge of the Mobile Broadband Experience
“RAN-aware real-time traffic management brings the operator closer to what subscribers wants to
do, when and where they are.” – European operator
Carriers control a precious
asset: information on
subscribers’ location, activity,
and devices
Yet, they feel distant from
subscribers
What’s needed: fine tune
services to match network
resources & subscribers’
behavior & expectations
How: active, real-time traffic
management
Encourage service adoption,
increased data consumption to
reach sustainable profitability
