Mobile Industry Observations
• Currently Over 3 billion mobile phone users, estimated to grow
to 5 billion in 2010
– Growing dependence on mobile connectivity
– Demand for Data mobility
– Significant increase in Data, video and application development
• Traffic growing exponentially due to consumer demand for
mobile data services for e-mail, text messaging, web access
etc
• Push for more bandwidth accelerated by new handsets such as
iPhones that combine digital media entertainment with web
based applications

Analyst Predictions, Statistics and
Trends
• Demand for bandwidth will grow
exponentially while revenue for the
operator will taper off
• Carriers are exploring various
technologies to provide cheaper
and more effective ways to meet
the capacity growth at a lower
CAPEX and OPEX cost
• Evolution towards Ethernet/IP
based mobile solutions
• Bandwidth demands

Backhaul the Critical Link
•The Mobile Backhaul network :
• Is the critical link between the mobile subscriber and the
network or the Internet
• Links the remote base stations and cell towers to the mobile
operators core networks
• Provide access to both the voice network and the internet

Mobile Evolution
With downstream data rates capable of delivering a theoretical 14.4 Mbps of user
throughput, the demand for bandwidth in the backhaul network is increasing by an order
of magnitude from where it is today
Impact of New Services on Backhaul
Circuits
• New services provide additional capabilities but
require more bandwidth.
• T1/E1 TDM Backhaul Circuits traditionally used
are ideal for carrying high-value voice services
but are not optimized for high bandwidth data
services.
• Backhaul links are becoming congested
Possible Solutions
• Separate mobile voice services directly at
the cell site.
• Data traffic can be backhauled using lower
cost broadband technologies (xDSL, cable
modem, Carrier Ethernet)
• Migrate all services voice and data to a
single platform that meets all the needs
required to deliver service to the customer
The Future of Mobile Backhaul
• Economic advantages of Ethernet will lead to its
widespread use for mobile backhaul networks
• Introduction of Ethernet and IP interfaces in
mobile base stations and radio controller
equipment
• Migration of legacy TDM circuits to Carrier
Ethernet Solutions
• Global Consensus and Adoption of Carrier
Ethernet Standards
Advantages of Carrier Ethernet
Backhaul
•
Ethernet
•
Most mobile data traffic is broadband/IP centric
•
Overcomes TDM (T1/E1) scalability
– Economically meets exploding bandwidth requirements currently constrained by the prohibitive
costs of legacy network upgrades
– Efficient and simple for service providers to manage and maintain
– Reliable with full SLA support and full OAM capabilities
– Ethernet is optimized for packet data traffic
– This makes Carrier Ethernet the compelling choice
•
Packet can be extended to the cell site over other physical technologies:

WiMAX
xDSL
Bonded Copper
GPON/EPON
Time/urgency
– Ethernet NodeB’s are being deployed now by all major networks
– Carrier Ethernet removes the barrier for timely network upgrades
Ethernet Options Solve Backhaul Cost Problem

 Backhaul traffic via TDM/SDH network
 All bandwidth is “nailed-up”
 All scaling must be planned well before
provisioning
 Separate networks for backhaul and core
Pseudowires – The solution to
the Internetworking Challenge
• Enable the use of new packet networks
• Provides a choice among multiple available
packet network technologies
• Uniquely combine circuit emulation and service
emulation over a packet network
• Deliver a solution allowing the transport of TDM,
HDLC, and ATM based services over framebased technologies such as MPLS, IP and
Ethernet Networks
