A brief history of EE From Bristol and Borehamwood to the whole of Britain
• EE was formed in 2010 following the merger of Orange and T-Mobile in the UK. Launched UK’s first 4G network in 2012
• T-Mobile began as Mercury one2one, founded in Borehamwood in the early 90s. It rebranded as one2one before purchase by Deutsche Telekom in 1999 and rebranding as T-Mobile
• Orange was founded in Bristol and in 1996 became the youngest ever company to enter the FTSE 100. It was acquired by France Telecom in 2000
• At EE we have 26 million customers, 15,000 staff and over 600 retail stores, all with one core vision: To provide the best network and the best service so that our customers trust us with their digital lives

1. Small cells in this presentation refers to all sites/cells that do not form part of the macro layer and are 4G
2. This includes
– Outdoor low power (5-10W) cells deployed in dense urban environments for capacity
– Outdoor low power (5-10W) cells deployed in rural areas for coverage
– Indoor low power (250mW-2W) cells deployed in dense urban environments for capacity
– Indoor low power (100mW-1W) cells deployed for coverage
– For simplicity this presentation does not include 2G, 3G, DAS or WiFi solutions

Building an innovative new network for Hetnet The EPC was a big leap as the first “all packet wireless core” – It was designed assuming a world of
homogeneous macro cells
If you were to design it today… for the HetNet …
– What would it look like?
– What enterprise capabilities would it enable?
9 Cambridge Wireless 03/04/2014
• Automated coverage and capacity management
• Virtualizing core capabilities and preparing for future ones
• Bring own coverage capabilities when needed
• Lower cost commodity hardware with network as software
• Support effective QoS by dynamically deciding on appropriate traffic priorities
• Resilience for reliability, mission critical uses

Enabling the Future of Enterprise Class Wireless Data
Cambridge Wireless 03/04/2014
Resilience for Enterprise Class Data
11
Architectural Resilience • Internet has resilience in its core design, homogeneous
legacy LTE network architecture does not • HetNets need to have resilience in their core design as
default operation
HetNet RAN Resilience
• To increase power from neighboring cells when a eNodeB fails
• For auto-configuration, including replacement of faulty RAN equipment
• For re-optimization as user patterns evolve
HetNet Packet Core Resilience
• Fault-resilient core functions via NFV/removing hardware dependence/graceful scaling
• Core virtualization to enable heterogeneous core also provides active/passive standby everywhere

Small Cells … Big Opportunities Specialised Nodes
• Your building is on fire and your Small Cell is
inside the building
• Your building lost backhaul connection …
• There is network outage or a natural disaster..
• A Small Cell could provide
– An instant network
– Self-configuring, self-healing, instant-on
– Mitigates interference
– Extend coverage
IF
Then

Small Cells … Big Challenges… HetNet is Evolving: • Different types of backhaul and network topologies: fibre
connected cells, multi-hop LTE backhaul
• A mix of in-building eNodeBs, dynamic in-vehicle eNodeBs, portables, and much more
• Network components supporting different 3GPP releases
• Different SON approaches for macro, small cell, and other types of access
Full interworking and seamless/secure handoff between macro layer and small cells
Dynamic common management, policy and content resource allocation and optimization

Small Cells … Big Challenges
Cambridge Wireless 03/04/2014
• Overload and congestion control • Resource sharing
• Small form factor • It’s not a beauty contest, but form factor matters
• Cost • Deployment and management cost must be low enough
to achieve lower Capex and Opex compared to macro
• Resilience • As the number of Hetnet components grow, they are
more prone to outages, physical breakdown, etc.
• Standardisation • Ability to use different vendor solutions seamlessly

Summary
15
• Small Cell solutions to support mission critical needs is an area of our interest, and we find it as one of the most innovative solutions in this arena
• We see 4G small cells as a solution to capacity needs in areas of high demand, and as a coverage solution in some areas, building on our 4G macro, typically in band.
• Hetnet in our views will provide higher levels of resiliency, interoperability, resource sharing and over all network intelligence at a lower cost.

We will do everything in our capacity to provide our customer with the best network and best service in the UK
Challenges will always be there, but we are prepared to face them

We believe that to find the limits of what is possible, sometimes we may need to go into the realms of what is perceived to be impossible
If you have something innovative which people think is impossible,
we would like to know more…..
