1. The Smart Way To LTE
Dr Shahram G Niri - NEC Europe
Broadband World Forum 2009 - Paris

2. LTE - Realizing True Mobile Broadband
•Broadband • Everywhere
Mobility •Mainly in Buildings •Affordable Mobile Broadband:
A reality today and to be the dominant means of
Mobile Broadband Mobile broadband connectivity in the near future But will need
Telephony Internet Broadband improvement in capacity, coverage, performance and
Today ~ 4 Billion operation yet at a lower cost!
Today ~ 1.2 Billion Today ~140 Million
<80% 3GPP family
• Lower TCO (LTE Vs HSPA+) Traffic
Cost Aggressive growth
HSPA+ needs major H/W upgrade to offer
Upgrades Life time
satisfactory performance & capacity; may have Moderate growth
short life time If aggressive mobile traffic NW capacity
Performance • LTE offers better user experience (lower
latency, higher data rate, better avaibility of
higher data rate, better QoE at cell edge)
LTE
Operation •Technology leadership HSPA+
HSPA Time
Higher revenues for 1st mover & Followers (in
order to remain competitive)
When
• Traffic per sub & number of connections and
therefore capacity demand
LTE: A cost effective, much better performance & •Spectrum availability & country regulatory situation
future proof technology for true Mobile Broadband •Service provision strategy
•Competitors’ movements

4. Think Big – Deploy Small Cells
Why LTE deployment derivers
• Use 2G and 3G networks (already provide macro coverage)
• Use 2.6GHz & deploy LTE initially for high data traffic hot spots
1 4
• Use an overlay cheap , easy to install and operate micro/pico /Femto LTE
• Address indoor coverage and capacity with LTE Femto enterprise
2
• Improve macro (HSPA) coverage by overflowing the traffic to LTE 3
• Use Digital Dividend later on & when the older technologies phase out for LTE macro
1 Capacity Driven
Benefits Hotspots and high traffic zones
• Invest where the traffic and hence the revenue is
• Improve your overall data traffic capacity and performance 4
• Start small and build as your number of users / traffic increases 3

5. LTE (eNB) & SAE (ePC) Deployment Options
Upgrade
eNB
Upgrade - SW & HW
• Most current NBs & xGSNs will not allow for a cost effective upgrade LTE
RF
RF
• Different/new requirements & no room for compromise 3G
• Technology limitations (e.g. processing, memory, power ) BBU BBU
• Risks of impacting existing 2G/3G performance
• Limit the choice of selecting the right vendor (best of breed Vs existing)
Overlay LTE
LTE Femto
New -> Overlay
New eNB & ePC - Dedicated eNB & ePC for high capacity & ePC SW
performance
• Freedom in terms of product form factor, vendor & deployment type 2G/3G HW
• Freedom in selecting best of breed
• Min impact on the existing NW performance S/P GW MME
• Faster rollout and suitable for initial deployments
• Choice of new platform independent of the existing platforms
S/P GW
• various deployment options xGSN
