29th IDATE International Conference

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

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?




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…?

Roadmap

Will the evolution towards 4G be incremental or revolutionary?

When do you expect 4G deployments?

Business conditions

Will the future system be able to deliver expected bit rates and costs?
