• Surge in devices and media-rich applications creates relentless demand for bandwidth and quality of experience
• Migration to 4G/LTE creates challenging architectural and scaling issues
• Mobile access network (MBH) represents up to 35% of MNO capex
ACCESS NETWORKS ECONOMICS ARE BREAKING
• Growing demand for business and residential broadband applications is straining existing access networks
• Service providers are struggling financially and operationally to provision, deploy, operate and manage thousands of 1GE and 10GE ports

IT’S TIME FOR A NEW ACCESS NETWORK
Vs.
Old
� Multiple access networks for different applications with many touch points
� Capacity focused – adding point to point bandwidth from access to aggregation
New
� Seamless end-to-end service delivery network for all applications and customers
� Operational intelligence and traffic steering make efficient use of existing bandwidth
7 Copyright © 2011 Juniper Networks, Inc. www.juniper.net
Vs.� “Innovation” has been limited to replacing TDM with Ethernet
� Macro cell backhaul
� Truck rolls often required for minor operational changes
� Inconsistent call quality (jitter, dropped calls, cell yell, etc.)
� Flexible services applied at the access layer and optimized per customer
� Macro cell AND Micro cell backhaul
� Remote provisioning for rehoming and other configuration changes
� Integrated synchronization for service quality and SLA commitment

Best solution is Macro and Small cell layers in separate spectrum.
LAYERED HETNET SOLUTION:MACROS + SMALL CELLS IN DIFFERENT SPECTRUM
• Large area, ubiquitous coverage• High-speed mobile users• Voice/Realtime services• Lower spatial reuse• Lower average user rate

Dense Small Cell layerFrequency f2Nomadic data
• Local, non-ubiquity• Nomadic/Stationary users• “Best effort” data• Micros/picos/femtos/APs• Higher average user rates
and scale independently
Separate spectrum simplifies and decouples the deployment
of the two layersLayers now deploy, optimize
and scale independently (for both RAN and Core)
COMBINED SYNCHRONOUS ETHERNET AND IEEE1588-2008 (PTP)Synchronization is a critical requirement for 3G/4G wireless networks

LTE SECURE NETWORKING OPTIONS
Backhaul Traffic SeparationUse L2 or L2.5 to create VPNs that naturally separate and protect router traffic. No S1-U ciphering (eNodeBbackhaul).
LTE lacks a ciphered backhaul interface for the use r plane (unlike 3G and 2G) so it may be required to secure backhaul when a 3rd party transport wholesaler is used
