2 Content! Market Information! Move to All Ethernet Mobile Backhaul! Why 480 Detail Features/Functionality Agnosticity in the backhaul Sample Migration Path! Sample Business Model Copyright Ericsson AB All rights reserved. 2
3 Mobile Backhaul - Current Status! Currently the biggest bottleneck in mobile networks! Need an efficient solution to improve cost-per-bit! Operators face large investments on backhaul to address new and upcoming high speed data applications HSPA, UTRAN LTE! Backhaul costs a high percentage of overall OPEX 40% of the OpEX in 2G 60% of the OpEX in 3G $22 Billion/yr Global Spend (Source: Yankee Group)! The market for mobile backhaul is huge, with Ethernet leading it The IP/Ethernet portion of mobile backhaul equipment revenue is set to explode! $36M in 2007, growing to $3.1B in 2011! 205% 5-year CAGR Copyright Ericsson AB All rights reserved. 3
4 TDM Leased-lines vs. Carrier Ethernet Services Price Comparison Nominal Prices Ethernet Leased-lines $ Price per bit Leased-line 1 2 Mbps 2 Mbps 2 10 Mbps 4 Mbps Mbps 34 Mbps 8 GBE 140/STM-1 Ethernet Source; A European operator 6-10 Mbps Bandwidth Operator Expectation: Lower Mobile Backhaul cost by 20-40% with Ethernet Carrier Ethernet services are more cost-effective than TDM leased-lines in capacities over 6-10 Mbps Copyright Ericsson AB All rights reserved. 4
5 Worldwide Mobile Backhaul Equipment Revenue ($M USD) $9,000 $6,000 $3,000 $135 $849 $764 $10 $26 Source: Infonetics 2008 $188 $167 $201 $546 $2,662 $198 $333 $2,380 $640 $246 $2,740 $1,522 $865 $280 $2,377 $2,595 $1,945 $320 $2,342 $3,702 $3,089 $ In Billions of USD $3,5 $3 $2,5 $2 $1,5 $1 $0.5 $0 Calendar Year Other PDH NIU SONET/SDH Ethernet Microwave Ethernet copper and fiber PDH/SDH microwave Revenue from Ethernet (Copper and Fiber) Copyright Ericsson AB All rights reserved. 5

7 Why Ethernet Backhaul! Ethernet to alleviate an Unsustainable Business Model: Increase in Bandwidth, plus increase in the cost of TDM (linear to increase in bandwidth); and flat ARPU! New Ethernet wireline (Ethernet over fiber or copper, DSL, etc.) costs are much cheaper! Ethernet is Cost Effective Easy to setup and operate Can t compromise on carrier class resiliency, QoS and OAM capabilities.! Ethernet speeds up convergence of wireline and wireless in the metro! Can utilize IP/MPLS over Ethernet for hard QoS and low-latency Copyright Ericsson AB All rights reserved. 7
