4. CHALLENGE EVERYTHING 2G to 3G was fairly painless HSPA pushes limits Customer experience becomes an issue Rollout 4G LTE In-fill with Wifi offload+Small Cells Densification is a table-stake Source: Heavy Reading 2012 small cell survey And the industry is preparedOr is it ? Small cell per macro forecast, 2013-15 So…

5. HOW FAR CAN WE STRETCH ? How does VoLTE change the game? How will on demand video affect customer experience? How does mobile cloud computing affect device + network dependency? 40% of advance mobile broadband users will churn in the next 12 months The Quality of Experience will be the key differentiator for converged operators

6. COVERAGE, CAPACITY, COST: “THE 3Cs” Elastic Backhaul Coverage: –Be able to cover a wide area with a single radio unit to prevent overcrowding –Be able to extend the range of your backhaul coverage easily through relay nodes

7. COVERAGE, CAPACITY, COST: “THE 3Cs” Elastic Capacity: –Supply more capacity than demand –Be able to scale capacity as demand grows –Look at providing at least 10x more capacity than existing wireless backhaul solutions

8. COVERAGE, CAPACITY, COST: “THE 3Cs” Elastic Cost: –Pay as you grow business models will be required –Be not only capex but opex efficient –Minimise installation, site rental and operational costs with compact units that can generate area coverage

19. ELASTIC BACKHAUL IN ACTION We must stop provisioning for the mean, And start stretching ourselves for the peak. Stretch your capacity, coverage and control costs. 2 Gbps, 1.5km2 Gbps, 1.5km 10x capacity of current solutions10x capacity of current solutions LTE-A eNB – 350 Mbps, total 1.4 Gbps HetNet cell – 50 Mbps, total 500 Mbps Relay (Extender)Relay (Extender) Compact, all outdoor, solution for low opexCompact, all outdoor, solution for low opex Extends coverage and capacity as new hot spots appearExtends coverage and capacity as new hot spots appear

20. ELASTIC BACKHAUL IN ACTION Create a right sized area of massive capacity that can easily be extended to in-fill new, unplanned hotspots. No need to compromise on customer experience at the expense of TCO

22. Predicting demand in network planning is increasingly difficult Service providers’ backhaul solutions need to stretch across all the sites that will need it, with no compromise in performance, coverage, and total cost of ownership HetNets are here, and will continue to evolve A solution is required that can: –easily extend gigabit coverage –allow providers to plan and delivery for peak cost effectively –Seamless integrate with small cells, wifi offload strategies This will enable converged service providers to cost effectively deliver massive network capacity with no compromise on customer experience SUMMARY
