MOBILE PHONES TO REPLACE TV AS PRIME AD MEDIUM
Mobile phones will replace TV as most important medium, says ad agency chiefBy Gary Silverman in London Published: April 7 2005 03:00 | Last updated: April 7 2005 03:00
Mobile telephones and other wireless communication devices will soon become the most important medium for advertisers to reach technology-savvy consumers, one of the world's leading advertising executives said yesterday.
The forecast by Andrew Robertson, chief executive of Omnicom's BBDO advertising agency, the world's third-biggest, underscores the uncertainties facing advertisers in developed markets as they shift from their traditional dependence on television.

What is 3G LTE
A step in performance and capabilities– Data rates up to 100 Mbps in local area
– Latency less than 10 ms
– Improved spectrum efficiency
– IP optimized
– Broadcasting
– Spectrum flexibility

3GPP Targets for Evolved UTRAN and UTRAfrom TSG-RAN meeting Athens Dec 2004: 1(2)
Increased data rates• Significantly increased peak data rate e.g. 100 Mbps (downlink) and 50 Mbps (uplink)
• Increase “cell edge bitrate” whilst maintaining same site locations as deployed today
Significantly improved spectrum efficiency ( e.g. 2-4 x Rel6)
Reduced latencies• Possibility for a Radio-access network latency (user-plane UE – RNC (or corresponding node
above Node B) - UE) below 10 ms
• Significantly reduced C-plane latency (e.g. including the possibility to exchange user-plane data starting from camped-state with a transition time of less than 100 ms (excluding downlink paging delay))
Designed for IP traffic• Efficient support of the various types of services, especially from the PS domain (e.g. Voice
over IP, Presence)
Support of further enhanced IMS and core network
Further enhanced MBMS

3GPP Targets for Evolved UTRAN and UTRAfrom TSG-RAN meeting Athens Dec 2004: 2(2)
Spectrum and deployment flexibility• Scaleable bandwidth
• 5, 10, 20 and possibly 15 MHz
• 1.25, 2.5 MHz: to allow flexibility in narrow spectral allocations where the system may be deployed
• Operation in paired and unpaired spectrum should not be precluded
• Possibility for simplified co-existence between operators in adjacent bands as well as cross-border co-existence
Cost effective introduction• Cost effective migration from Rel-6 UTRA radio interface and architecture
• Support for inter-working with existing 3G systems and non-3GPP specified systems
• Backwards compatibility is highly desirable, but the trade off versus performance and/or capability enhancements should be carefully considered.
• Reduced CAPEX and OPEX including backhaul
• Reasonable system and terminal complexity, cost, and power consumption.

Ericsson assumptions for S3G
• OFDM based radio
• S3G radio will support PS bearers only
• Common upper layer protocols between WCMDA PS-domain and S3G• Simplified S3G deployment• Seamless mobility between WCDMA PS-domain and S3G• Only one standard, common for WCDMA PS-domain and S3G, for
the 3GPP evolution
• S3G shall be possible to deploy as a stand-alone system
• Easy migration into all spectrum (e.g GSM) spectrum is essential
21 Open Workshop on NGN, Brussels, June 22, 2005© Copyright Ericsson AB 2005. All right reserved.
• The IP-optimized Layer2 and Layer3 protocols in Super 3G should be applicable also for HSDPA to enable:- Cost efficient roll-out of Super 3G starting in areas with need of high data rate - Efficient hand-off for service continuity between WCDMA/HSDPA and Super 3G- Cost efficient upgrades of existing WCDMA/HSDPA equipment to Super 3G
Cost efficient roll-out of Super 3G by sharing common IP-optimized protocols with WCDMA/HSDPA

Summary
• An important aspect of an NGN network is a multi-capable access
• Mobile systems are already evolving to have the capability to cater for Mobile Triple Play
• Voice already today• HSDPA and Enhanced UL for “ADSL” access to internet• HSDPA and MBMS for mobile TV
• 3G Long Term Evolution ensures the specification of a multi-capable access that is capable of carrying a wide range of different types of traffic also in the beyond 2010 time frame
