•  Who we are, what we do, how we do it: Our release program

•  What’s the small cell forum doing about… Backhaul •  Residential •  Enterprise •  Urban •  Rural and Remote

•  Coming soon… Fronthaul for Virtualised Small Cells

Overview

Who we are:

65 operators covering 3 billion global mobile subscribers – 44% of total

Providers of small cell technology representing all parts of the ecosystem

The Small Cell Forum Comprises 140 Mobile Operators and Technology Providers working together to accelerate commercialisation

Clarifying drivers and providing example operator business case

We report on these using our Release Program

What we do: Accelerating adoption of Small Cells

Lobbying and tracking regulator activity

Identifying barriers to adoption

Driving consensus into standards

Sharing success stories and best practices

Tracking and reporting market progress Organising Plugfest Events

The release program: Covers all angles on all types of small cell

•  On site LAN needs to be configured to support small cell traffic •  WAN backhaul likely to be operator provided to ensure QoE of voice service •  A small cell centric SLA includes:

•  Backhaul bandwidth provisioned according to end user usage as opposed to small cell capacity limits

•  QoS prioritisation and security features

Provides  guidance  on  LAN  configuraXon  and  WAN  SLA  

11

• Urban small cells are cells deployed by operators in areas of high demand density on an open-access basis to all the customers of the operator.

•  They can be deployed outdoors on street furniture or indoor public locations such as transport hubs and retail malls.

What’s next for Small Cell Backhaul?

© Small Cell Forum Ltd 2015

•  Small Cell Forum’s release program reports on a range of activities which accelerate adoption of small cells towards large scale commercial deployment

• Operators identify backhaul, sites and deployment as key challenges for public access small cells

•  Forum members have worked together to develop best practice guidelines on business cases, technologies and processes. All downloadable from www.scf.io

• Get involved to shape industry thinking on small cell evolution: Virtualisation, LAA, Lean Deployment, SON and more…
