3G+, 3.9G or 4G?
4G is a general term referring to systems beyond 3.9G
Following the ITU terminology, IDATE assume 4G technologies will begathered under the IMT-Advanced umbrella
We propose the following roadmap for 4G developments:
4G still in research status but first elements are already there: LTE, UMB, 802.16m firstreleases in 2009.
Detailed IMT-Advanced specifications by 2009
Commercial IMT-Advanced networks are generally expected from 2012 / 2015

Technical RequirementsCompetition among access technologies
But at least, 3 competing standards are expected to be candidate forIMT-Advanced approval:
3GPP LTE
3GPP2 UMB
IEEE 802.16m
TD-SCDMA evolution?
Strong European position onstandardization and spectrum allocation
would strengthen European industry

Longer term developments: network architecture, SDR and CR
Longer term approaches to future mobile networks consider disruptive technical features
Cognitive Radio: dynamic spectrum access Software defined radio: remote software upgrades at terminal and network levels
Mesh networks with multi hop relays capabilities
The roadmap of these approaches could differ from IMT-Advanced agenda

SDR and Cognitive
radio :Full dynamic spectrum
allocation from 2015 /2020.
SDR: Soft upgradesfor mobile devices
from 2011.
Multiplication of
standards in mobile
devices (GPS,WiMAX, 3G, WiFi).
Cognitive radio: Smarter
cognitive radios techniquesfrom 2010.
(DECT already available )
SDR. Many experiments.
Platforms capable to connect
into WLAN (802.11) or UMTS(W-CDMA) networks, or to actas HDTV receiver.
Wired remote upgrade in base
stations from 2007.
Mesh networks. Manyexperiments.
Will the evolution towards 4G be incremental or revolutionary?

4G will allow fully ubiquitous services
The consensus is that users should have access to broadband internet
wherever and whenever they want through a wide range of terminals.
4G at the crossroad of Internet protocol, mobility and broadband.
Convergence is happening at three different levels.

Key enabler: radio spectrum requirements
Wider bandwidth
Data rates increase OFDMA performance improved with
wider channels
Up to 100 MHz channels to deliverexpected bit rates
Between 500 MHz and 1 GHz ofadditional radio spectrum formobile services below 5GHz
WRC 07: IMT-Advanced candidatebands
What came out of the WRC 07?
Peak data rates and channels for 3G and B3G technologies

29th IDATE International Conference
Operators’ criteria of choice for future access technologies
When deploying new mobile infrastructures, operators could decide to
switch to another technological path: Examples of migration from CDMA/EVDO to HSPA/LTE
Greenfield deployment of new access technologies
Operators’ main criteria for technology selection:
Deployments heritage
System performances
Ecosystem and roaming capabilities
Open standard / open interfaces
IPR policy
Radio spectrum availability and licenses’ conditions
Structure of the mobile services market
CAPEX and OPEX
There is a gap betweenoperators expectations and
vendors propositions
Agreement needed betweenoperators and vendors onroadmaps, IPR, spectrum
allocation…?

Business models meltdown
4G will reinforce the disruptive trends observed with latest 3G evolutions:
Mobile Internet: full browsing and peer to peer dominated ecosystem Vs. walled gardenstrategies
Accelerated trend towards voice commoditization
Improve business conditions for data offerings: lower cost per bit carried
Will the future system be able todeliver expected bit rates
and costs

Business models meltdown: no rush for 4G
Financial and competitive issues could slow adoption of future mobile
technologies by mobile operators:
Mobile operators want to avoid 3G failures:
High prices for spectrum licenses
Slow take off of customer adoption
Uncertainties about business models are weighing on operators’ strategies:
Defensive approaches to future developments
Mobile operators are facing increased competition: fixed operators, service providers,devices vendors
Mobile operators tend to slow the pace of investments in network infrastructures
When do you expect 4G deployments?

29th IDATE International Conference
Questions to panelists
Standardization
Do we need a European position on standardization and spectrum allocation?
What came out of the WRC 07?
Ecosystem _ positioning of operators and equipment vendors
Is there a gap between operators expectations and vendors propositions?
Do they need to agree on roadmaps, IPR, spectrum allocation…?
