WE MAKE BROADBAND NETWORKS WORK

WIRELESS EXPERT IN ADVANCED IP NETWORK MIGRATION

The Global Broadband Data Explosion

• Massive growth in mobile traffic and demand for mobile video and applications

• Major Government sponsored drive for broadband delivery to the underserved around the world

FEBRUARY 2010, VERSION 1B2 AVIAT NETWORKS |

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

FEBRUARY 2010, VERSION 1B3 AVIAT NETWORKS |

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

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

FEBRUARY 2010, VERSION 1B7 AVIAT NETWORKS |

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

Right-Sized to Win

Aviat is unlike monolithic telecommunication vendors, who subscribe to a “one size fits all” approach to serving operators – large and small.

This often results in vendor lock-in, compromised bundled solutions, slow pace of innovation, proprietary technology, and inattentive or complacent service and support.
