Ethernet Mobile Backhaul is Forecast to Soar
Mobile operators shell out $19.5B in mobile backhaul service charges in 2006

Infonetics Research, April 2007
The cost per mobile backhaul connection for leased lines PDH and ATM over PDH is about two and a half times that of new wireline connections (Ethernet, DSL, cable, PON), now and in 2010

Ethernet makes up just 1% of total mobile backhaul equipment revenue in 2006, but is forecast to soar to $2.5 billion by 2010, at which time it will represent 41% of the market

Mobile Backhaul Network Market
• Qualitative estimates for markets– US: ca. 90% leased lines
– Middle East & Africa: ca. 90% microwave radio links
– Europe: ca. 60% microwave radio links
– World: 50% to 60% microwave radio links
– Carrier Ethernet implementation divided roughly equal between Copper/Fiber and Wireless media
• Projected growth focus of mobile access networks– US & Europe: Increase in bandwidth only to existing sites
– Emerging markets: Build-out of new access and backhaul networks
– Carrier Ethernet plays an important role in network growth planning
MEF work for mobile industry is relevant and timely

Backhaul Evolution
Migration to Carrier Ethernet
8
• Cost and revenue decoupling• Define Ethernet services • Multiple technologies GSM, WCDMA, CDMA2000, and WiMAX 802.16e• Base stations collocation• Leverage install base
Business Challenges
• Increase Bandwidth• Increase Reliability• Adapt to multiple underlying available media: Fiber, Copper and Microwave• Adapt to multiple migration requirements• Service assurance and manage SLAs in the mobile backhaul networks
Deployment Challenges
Mobile Operator Challenges
• Current architectures are based on GSM GERAN and UMTS release R99 UTRAN access networks• Migration to UMTS R5 defines an all-IP network option
9
Reality of Network Migration
GSM
Abis interface is TDM based and carried over E1/T1 links
Circuit emulation required for Ethernet transport
UMTS R99
ATM connections carried over E1/T1 IMA links
Circuit emulation or Pseudowires required for Ethernet transport
UMTS R5
has all-IP access network option
Suitable for Carrier Ethernet, depending on base station config
CDMA 2000 EV-DO offers T1 or Ethernet interfaces at base stations
Mobile Core Network
Evolution
Towards IP/Ethernet
Split MSC architecture with IP/Ethernet interfaces
IP/Ethernet links between media gateways and MSC servers

Advantages of Ethernet Mobile Backhaul
Cost savingLower CAPEX and OPEX
Revenue per bit
Scalability
Ethernet services scale to meet traffic demand at radio sites
Architecture scaleability to meet current and future mobile network dimensions
Legacy supportSupport legacy deployments
Fixed mobile convergence
Ethernet allows both mobile, triple play, and enterprise services to run over the same network
Standardized services
Network carriers can offer new services
Ease interoperability and comparability

Work Groups, Scope and Timeline
12
MEF Work Groups for Mobile Industry
• Carrier Ethernet for Mobile operator network evolution– Mobile operator defined by using mobile networks as per GSM,
3GPP/3GPP2 (UMTS, CDMA2000) or IEEE802.16e (mobile WiMAX)
– Carrier Ethernet is PHY independent – It can be transported over copper, optical, or wireless media
• Marketing working group– Focus on industry education and market research
– Participate in mobile industry trade shows and conferences
– Liaise with analyst and telecoms press
• Technical working group– Technical project defines a Service Implementation Agreement (IA)
for Carrier Ethernet services in mobile operators backhaul networks
– MEF Service IA release planned for Q4/2008 or earlier
– Liaise and work with other organizations, e.g. MFA Forum
13
• Single MEN• Define Ethernet services • RAN backhaul part of mobile backhaul• GSM, WCDMA, CDMA2000, and WiMAX 802.16e• ‘Transparent’ or out-of-MEN sync methods• 4 main use cases
Scope of Phase 1
• Main use cases• Ethernet Service Types• CoS• Performance• Synchronization• Ethernet OAM• Protection and fault recovery• UNI Type definition

Technical Project Timeline
• 07 Q1 – Present project proposal to Technical Committee (TC)
• 07 Q2 – Use case specifications for Implementation agreement (IA)
• 07 Q3 – Initial draft of implementation agreement– Industry Survey Launch
• 07 Q4 – Approved draft, first straw ballot on implementation agreement
• 08 Q4 – Letter ballot of IA (might be earlier)Process is on track.
Interop lab demos based on IA draft are expected in 2008

New Terms for Mobile Backhaul Services
• RAN CE – generic term for mobile radio access network node or site; may depict both RAN NC & RAN BS nodes
• RAN NC – a RAN network controller or network controller site• RAN BS – a RAN base station or base station site• RAN I/F – a non-Ethernet based interface between a RAN CE and GIWF• GIWF – Generic Inter-working Function; enables a RAN CE with a RAN I/F to
connect to a UNI
