WIRELESS BACKHAUL SOLUTIONS ENABLING THE 4G/LTE FUTURE

IP MOBILE BACKHAUL SOLUTION

Global Broadband Data Explosion

• Mobile subscriber growth

• 1B to 3.5B subscribers in 3.5 Years

• More Mobile lines than fixed in the developing

world

• Demand for Smart phones

• Data traffic volume from mobile devices

growing by more than 10X per year

• Broadband video will drive 80% of

mobile traffic

The Operators' Dilemma

Operators must expand their market reach and introduce new differentiated services

Their Networks need to be upgraded to keep up with Smartphone driven data demand and prepare for 4G/LTE

However they often lack time, and internal resources and expertise


The Broadband Data Explosion – the AT&T experience

6,732% growth in traffic in past 13 quarters

3% of users generate 40% of traffic

Added 2,000 new cellsites and 100,000 backhaul circuits in 2009


Sources: Ralph de la Vega, AT&T, New York December 9, 2009

More and More Cellsites

Nearly 1 million new sites

worldwide by 2013

Fiber is the natural choice for LTE

backhaul, but connects less than

20% of sites today

Copper lines will not provide the

capacity scalability needed

Microwave is the natural choice

for sites where fiber cannot reach

economically

The Mobile Internet Tsunami meets the Backhaul Bottleneck

Backhaul is the central battleground for LTE network migration

Even now backhaul is not meeting the demand of 3G/HSPA

LTE backhaul requirements are still not well understood by operators


Mobile Backhaul Networks Must Evolve

Mobile backhaul networks must evolve

Maintain essential high- quality TDM voice services

Gradual migration path to all-IP for next generation 4G/LTE
