Webinar slides with presentations from David Chamber/ThinkSmallCell and Amit Jain/Spidercloud contrasting the various Enterprise small cell architectures. The webinar considered building size segmentation, 3G/4G technology mix, alternative approaches for distributed radio and controller functions, with a forward looking section covering LAA, MulteFire and shared spectrum A Q&A session touched on the impact of Wi-Fi, how Enterprise IT departments look at co-existence of LTE/Wi-Fi, and whether small cells can be used to provide full multi-operator service.

3G and LTE Enterprise Small Cell Architecture 2016
- 4. © 2016 ThinkSmallCell Ltd. Growing emphasis on indoor soluKons • Outdoor-in LTE reaching its limits – Vodafone London, £200million but 40% deep indoors unlit • More commercial value in LTE vs Free Wi-Fi – EE posiKon themselves for network “onload” • Neutral host iniKaKves emerging – Some operators see value in differenKaKon, others in collaboraKon
- 5. © 2016 ThinkSmallCell Ltd. • LTE-only is not yet viable in many countries – VoLTE not yet widely deployed; CSFB to 3G common – SubstanKal proporKon of handsets sKll 3G only – Verizon, China Mobile early adopters • 3G-only is considered limited term investment – Ideal soluKon would be both 3G/4G capable • Recent mulKmode deployments include T-Mobile USA, America Moviles, Free France, Vodafone Group etc. 3G vs LTE vs MulKmode

Looking Ahead - Roadmap for Enterprise Small Cells 17 Technology Benefit LAA LTE 2x Capacity without 2x Spectrum in Single Operator Small Cell Deployments MulteFire Neutral host LTE in venues (where business case for single-operator small cells does not work) Authorized Shared Spectrum Neutral host LTE in venues Private LTE networks • LAA is part of 3GPP R13 and likely to be launched in 2017 to add network capacity • MulteFire requires standardization in 3GPP or similar organization. Will work in existing 5 GHz spectrum • ASA (aka CBRS in US) requires regulatory approval, standardization, and spectrum database systems

- 19. © 2016 SpiderCloud Wireless, Inc. DAS & RRH Systems Unsuitable for Unlicensed 19 Baseband Unit will lose opportunities to use unlicensed spectrum 1. LTE scheduler must either decide to use unlicensed channel after monitoring it for 34 µs, or risk losing channel to Wi-Fi AP 2. Each centralized baseband cell will overlap with dozens of Wi-Fi APs. If any of these Wi-Fi APs uses the channel, it will back-off Baseband Unit Ch1 Ch2 Ch3 Ch4 Ch1 Ch2 Ch3 Ch4 Ch1 Ch2 Ch3 Ch4 Wi-Fi AP LTE-LAA Baseband Unit connected to multiple remote radio heads. All RRHs use same channel for LAA Remote Radio Heads (RRHs) Coverage area of RRH Remote Radio Head Aggregator Baseband Unit and connected RRHs will reduce Wi-Fi system capacity 1. Baseband unit connected to multiple RRHs occupies the channel in a much larger region that it needs to service its subscriber 2. All Wi-Fi APs that use same channel as LTE cell will find the channel busy and will back-off, reducing Wi-Fi system capacity
