• 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


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

Macro layerFrequency f1

True seamless mobility


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


Propagation of frequency over physical layer more accurate than over packets

SyncE used to derive frequency and PTP used to drive phase

SyncE and PTP traceable to common source

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
