OUTDOOR SMALL CELL GROWTH Operators start to shift from targeted hotspots to large-scale deployments Densification programs Spectrum availability Shift to capacity Maturing of HetNet enablers Drives demand for small cell backhaul $6.4bn spend between 2016 and 2020 on outdoor small cell backhaul kit (IHS) 85 173 287 412 528 667 13 20 30 50 67 88 0 200 400 600 800 2015 2016 2017 2018 2019 2020 ,000units Urban Rural+Remote Outdoor small cell shipments Source: Mobile Experts

- 6. BACKHAUL IS A MAJOR HEADACHE AGAIN Survey of over 65 MNOs - small cell barriers to mass deployment Backhaul has moved back up their priority list Changed from technology issue to one of scalability, process and architecture Many issues of 2013 have been addressed, new ones have arisen 2013 2015 2017 Backhaul Automation Automation/ scalability Securing optimal sites Integration with other networks Backhaul Provisioning and management Monetization Site issues Monetization Backhaul Monetization Site costs Site issues New architectures e.g. virtualization Top 5 barriers to outdoor deployment of small cells Source: Rethink MNO survey
- 7. THE CHANGING BACKHAUL ISSUES Was a technology issue … but More solutions coming to market More fiber in many markets, including dark fiber NLOS wireless backhaul maturing Self backhauling and aggregation New spectrum Still performance issues but higher confidence these will be addressed More providers entering space eg cablecos, SCaaS New issues are about large scale logistics Regulation non-harmonized eg street furniture SON needed to lower costs MNOs want standardized repeatable processes from site negotiation to management Uncertainty re spectrum, mmWave targeted for 5G access Virtualization – cost efficiencies and flexibility, but fronthaul issues Rural and remote issues Small cell backhaul is a moving target, will be central to new Small Cell Forum work program

- 9. 1 Regulation regarding telecom equipment installation varies with location • There is no clear and uniform regulation on how telecom equipment should be installed in public areas, street furniture, etc. Not even in the same country 2 NLOS wireless backhaul performance doesn’t fulfil expected targets: • Trials find uneven performance due to urban environment (trees, vehicles, …). Small Cell wireless backhaul performance lower than traditional wireless backhaul solution for Macro, but it is expected to provide similar performance between Macro and Small Cell 4G sites. 3 Today’s Small Cell wireless Backhaul is far from being “plug, play and forget” • Self-healing or self-organised features are not fully deployed, resulting in (unexpected) high O&M costs 4 High Uncertainty over Wireless Backhaul Spectrum • Unlicensed spectrum plus further 5G spectrum allocation is throttling Small Cells wireless backhaul rollouts.

- 10. We are keen to encourage further work into backhauling, the sort of things we have in mind are: • Self-backhauling options/techniques, • how backhaul options affect antenna design, • how to do backhauling for high-density deployments, • how to do backhauling for high reliability • Urban densification is definitely of interest, particularly comparison of different backhaul & fronthaul options: • Wireless options are very important to us as well as fixed-line • How can different functional splits be deployed over fixed line, both fibre and copper? • Can G.Fast support RRHs with a higher layer split than CPRI? • Can we make more efficient use of fibre assets using higher layer splits?

- 15. Urban Densification • 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. 15

Enabling Digitalized Enterprise Education of verticals – Via Enterprise Taskforce marketing group will develop an education program geared to specific vertical segments with a particularly urgent need for small cells. Internet of Things – defining the most promising commercial use cases for enterprise and vertical IoT services that rely on small cells, and ensuring the key technical elements are in place. Mobile Edge Computing – developing common frameworks based on ETSI MEC for delivering content close to the user, personalizing services and analyzing data locally, in order to add value to the enterprise small cell case. Multi-operator – detailing the business case and the enabling technologies for multi-operator and neutral host platforms, with a direct route towards 5G concepts like network slicing. Unlicensed – focusing on the enterprise aspects of deploying small cells in licensed, unlicensed and shared spectrum, including technologies such as LWIP (lightweight IP). What next: SCF Work Streams 2016-2017 Deploying Hyperdense Networks Interoperability – ensuring that enabling technologies, such as NFV, management and orchestration, and automation are fit for 5G purpose and fully interoperable. Backhaul – delivering affordable gigabit backhaul to meet next generation capacity requirements everywhere.

Editor's Notes
- #19: Looking for a clear way of describing this to journalists – two main workstreams: Deploying Hyperdense Networks and Enabling Digitalized Enterprise Looking for Champions. So far Deploying Hyperdense Networks, championed by AT&T, Jio; Enabling Digitalized Enterprise, championed by Orange, Vodafone; Hoping Ericsson & Huawei might do hyperdense Hoping Cisco, Spidercloud will do Enterprise – Spidercloud to carry on, Cisco because Lisa kicked off the taskforce
