Macro Access Offload Three Parallel Tracks

Metro/Hotspot Access

Residential Access Office Based

Metro WiFi deployments driven by spectrally challenged operators

Stadium traffic set to dwarf any licensed capacity installed by MNOs

Licensed/Unlicensed Hotspot becoming an integral part of MNO offload strategy

Metro WiFi operators leasing real estate/ power/backhaul to MNOs for Pico deployment

Initial coverage based femto to address churn

Peak consumption occurs drives compelling macro offload economics

MVNO economics motivating MVNOs to accelerate residential macro offload deployments

Enhanced community deployments allows increased macro offload in dense urban environments

After, residential, office is second peak of consumption

Guest WiFi evolution facilitates ease of use of WiFi offload using enterprise infrastructure

Enterprise femto provides in-building coverage and enterprise capacity offload from macro cell

Enterprise GWs allow differentiated managed service opportunity.

Summary Small Cell Drivers

Future Networks supporting the Mobile Internet will need to seamlessly integrate a lot more smaller cells

Shifting from 104 cells to 106 cells will require a change of mindset and management automation

Key decisions that need to be considered:

Whether to use unlicensed, licensed technology or both? Unlicensed already being deployed for BYO offload Unlicensed suited to very high density deployments Licensed already delivering integrated mobility Licensed enables control over spectrum/interference Small Cell TCO driven by real-estate, power and backhaul

SERVICE PROVIDER WI-FI EVOLUTION


Recognized Evolution of SP Wi-Fi Capabilities

Yesterday

Web Authentication, no over the air security, open to simple MAC-spoofing attacks

MPC/EPC integration requires I-WLAN IPSec overlay

Charging records can be repudiated

Tomorrow

HS2.0 deployments

MSAP based service discovery

Heterogeneous Network selection and load balancing

Seamless WiFi/Cellular mobility

Today

802.1X/EAP based authentication and over the air encryption

Clientless MPC/EPC integration with seamless access to operators network

Wi-Fi Security moving centre stage for Service Providers

Now, it may be considered by operators that the security strength and ease of use of Wi-Fi is as acceptable as 3G/LTE. For example, the operator controlled hotspot with 802.11i could be treated as the trusted Non-3GPP Access. Source: 3GPP

Service Provider Wi-Fi Evolution

Over the last 12 years, Cisco has been defining and delivering Wi-Fi solutions for our Service Provider Customers

Now, more than ever, the industry accepts that traffic and signaling need to be offloaded from the macro RAN network

Ciscos goal is to enable a 4G like experience over Wi-Fi radio bearers

Over the last 3 years, Cisco has been developing an architecture based on 3GPP standards to enable the integration of a small cell SP Wi-Fi solution into scalable, converged policy and charging infrastructure

A unified architecture that is applicable both to MNO and non-MNO operators alike

Able to support legacy web-based traffic, but future-proof to support the latest use cases in terms of automated EAP based authentication and LTE seamless mobility

Recognized Evolution of Small Cell Licensed Radio Moving out of the Home

Today

Small Cell Licensed Radio solutions focused on the residential market

Home Node B primarily addresses poor in-home coverage

Effective churn reduction tool

Cost reduction opportunities as traffic gets offloaded from the macro network

Tomorrow

Small Cell solutions move out of the residential market

Enterprise use cases drive new requirements in terms of power, number of users, mobility and services

Transition outdoors as macro-small cell co-existence capabilities gets deployed

Release one [launched February 2013] is aimed at residential small cells. Release two is geared towards rapidly driving Enterprise small cell deployments within non-residential business environments.

Summary Integrating Licensed and Un-licensed Systems

55

The future growth in Mobile Internet consumption necessitates a shift to small cell systems

Cisco is executing on a converged architecture that is able to leverage licensed cellular and un-licensed Wi-Fi small cell access points

Service Provider Wi-Fi targets delivering a 4G experience using 802.11

Small Licensed Radio System targets delivering cellular coverage and capacity to indoor locations

Converged Access Points and Converged Gateways enable operators to lead with venue centric Wi-Fi propositions and then leverage the same gateway, real-estate, power and backhaul for licensed radio coverage and capacity

The orders of magnitude involved mandate a fundamental shift in tools, including self organizing and optimizing capabilities

Ciscos Quantum RAN Optimization leads the way in cellular SON delivering a set of tools necessary to accelerate the adoption of small cells
