•  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

[078] Enterprise Small Cells

© Small Cell Forum Ltd 2014 Enterprise SCBH comprises separately managed LAN and WAN

segments

• 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.

12

•  “Finds benefits of small cells outweighs the costs to yield a positive business case overall, even where an operator plans to evolve both macrocell capacity and spectrum holdings as well

•  Although timing and quantity of deployment will vary markedly amongst operators, we nevertheless see that a fully-featured small cell layer will be an essential component of future networks”

•  Perspective of the people, tools and processes needed to plan, design, build and maintain urban small cell networks

•  How processes which have typically been the domain of the mobile operator from a macro-cell perspective can be streamlined and/or outsourced for potential cost savings in large-scale small cell deployments.
