• 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

• 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

25. • 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.
