This is Broadband everywhere


Broadband everywhere adds value

Users quickly get used to everywhere access

“the ability to connect the Mobile workforce to the main office with a mobile

PC is becoming a critical productivity factor for both private and public sector...”

EU Commission, June 2004

50% agrees on the statement “Having high speed Internet everywhere is

important to me”ConsumerLab Internet Frontiers study 2007


HSPA enables new business

Broadband on the move� Attracts more passengers� Preferred choice for longer rides

Healthcare to all and everywhere� Enhanced consultation service to patients� Increased number of patients

Enterprise Business� Effective Fleet Management� Improved customer services

Mobile connectivity increases productiveness


Case Study: Telstra provided HSPA to 98% of pop in 10 months.HSPA 14/1.4 Mbps nation wide, up to 200km cell range

HSPA enables cost effective broadband to all...

HSPA Evolution


� Spectrum flexibility:– Use of new, re-farmed or unused spectrum– FDD and TDD– Variable channel bandwidth

� Performance:– Higher peak rates– Higher bandwidth– Designed for ”always on applications” from start

� Cost:– IP-based flat Network Architecture

(no circuit switched domain)– Low OPEX– Simpler operation with less to configure and higher degree

of self configuration

Driving forces behind LTE


3GPP LTE performance

� High data rates– Downlink: >100 Mbps– Uplink: >50 Mbps

� Low delay/latency – User plane RTT: <10 ms– Channel set-up: <100 ms

� High spectral efficiency � High Performance

Broadcast services� Cost-effective migration

� LTE radio access– Downlink: OFDM– Uplink: SC-FDMA

� Advanced antenna solutions– Diversity– Multi-layer transmission (MIMO)– Beam-forming

� Spectrum flexibility– Flexible bandwidth

(1,25 up to 20MHz) – New and existing bands– Duplex flexibility: FDD and TDD

1G1st Generation (1970’s, national spectrum)

– NMT, AMPS & TACS

What is a Generation?

2G2nd Generation (1980’s, CEPT)

– GSM, PDC & cdmaOne

3G

3rd Generation (WARC-92 & WRC-2000, ITU, global spectrum)

– IMT-2000 (WCDMA/HSPA & cdma2000 EV-DO)– Evolved 3G (LTE and EV-DO rev C)

4G4th Generation (WRC-07, ITU, global spectrum)

– IMT-Advanced

A Generation is defined by a technology and spectrum harmonization event


IMT-Advanced- more bandwidth needed

•• Increased voice trafficIncreased voice traffic

•• Increase in information based trafficIncrease in information based traffic

•• New capable services require high data ratesNew capable services require high data rates

--> need for an enhanced> need for an enhanced radio technology, radio technology, providing yet higher peak data rates and shorter providing yet higher peak data rates and shorter

IMT-Advanced cannot only be deployed within the current spectrum

Goal:• 50 - 100 MHz channels• Speeds of up to 1 Gbps

Conclusions

� Demand for Mobile broadband

� HSPA, already a huge commercial success

� HSPA on par with fixed broadband and evolving (40-80Mbps)

� LTE for increased performance (>150Mb/s) and cost efficiency

HSPA, 70% of mobile broadband subscriptions 2012
