This document discusses the challenges of deploying small cell networks and the role of wireless backhaul solutions. It contains the following key points: - Small cell networks are aimed at providing cost-effective cellular capacity and coverage where needed, but challenges include seamless integration with existing macro networks and supporting various mount locations. - Wireless backhaul is preferable to fiber/Ethernet in many cases due to limited availability of wired solutions in areas needing capacity/coverage and the lower cost of deploying wireless networks. - Fastback Networks provides wireless backhaul solutions for small cell deployments, having deployed over 10,000 units with tier 1 mobile operators to address both macro and small cell connectivity needs.

3. The Small Cell Challenge
• Goal
– Cost effective cellular capacity and coverage where needed
• Requirements
– Seamless operation with existing Macro Network
– Fill-in coverage and capacity gaps
– Supports location flexibility
– Low-cost (TCO/ROI)

4. Why Wireless?
4
• Limited availability of Fiber/Ethernet/Broadband where
capacity and coverage is needed
• Cost to deploy fiber/Ethernet/Broadband where it is needed
• Speed to deploy
• Multitude of mount locations and types
• Long term TCO/ROI
• 5.XGhz can work in NLOS and nLOS situations, support twist &
sway of street level mount resources

5. Network Densification – the Challenge
5
• Cellular base stations will migrate from towers and rooftops to street level

12. Lessons Learned
12
• Need a rich tool-box of solutions
• TCO/ROI of Wireless is generally superior
• Training of the install team is critical
• Each municipality will offer unique challenges and
opportunities – very difficult to establish cookie-cutter
approach
• NLOS is not a science, but getting easier to predict
