Editor's Notes
- The Road to Densification Level Setting the terminology Each carrier brings a different starting point to the densification story (some are more dense than others) The term smallcell can be used to mean many things Densification in reality is investment below the clutter (<70” and indoors) Demand Projected demand will trigger densification to meet capacity and speed triggers Operators will have to purchase spectrum, densify, and consider unlicensed spectrum options HetNet Yesterday – a mix of solutions that didn’t always bring a seamless customer experience Tomorrow – HetNet will blend celuular, wifi across customer experience HetNEt lays the foundation for 5G
- Macro Typically above the clutter, greater than 40watts (approx. 80% of ATT network today) Micro/Pico (outdoors) Typically <70’ in the clutters, 1-20 watts (approx. 16% of ATT network today) Micro/Pico (indoors) Indoor deployment ranging from 50miliwatts to 1watt (approx. 4% of ATT network today) ATT network is currently competitively dense Operators w/ the lowest site density will typically begin to densify sooner than others Desnification is a blend of macro-micro-pico below the clutter
- Yesterday A mix of solutions that did not always result in the most efficient use of network assets Long lead times Tomorrow A blend of hetnet solutions across macro-micro-pico-wifi w/ licensed and unlicensed convergence Considerations Public vs Enterprise driven demands Opex, CapEx, Cycle Time Layer Management – Capacity, Technologies, and transport soltuions
- ATT Deployment Strategy Starting point Strong network density Balanced low/high spectrum portfolio Surgical densification in future years Macro Maximize LTE carrier adds against existing macro and spectrum portfolio Micro Drop below the 70’ clutter and deploy 20watts and less solutions Pico A blend of 1watt or less indoor/outdoor solutions Converge micro/pico across unlicensed WiFi as standards progress
- ATT Densification ATT must densify as macro LTE carrier adds exhaust across spectrum portfolio ATT will continue to surgically deploy micro/pico (Smallcell) for capacity and speed in 2016-2017 ATT forecasts critical mass of densification triggers in 2018+ ATT must densify across all morphologies (Urban, Suburban, rural) utilizing macro-micro-pico as well as convergence w/ unlicensed options
- The path to 5G Densification - Demand drives operators to acquire spectrum, densify and consider unlicensed options Macro-Mirco-Pico HetNet - Blending cellular, WiFi, and customer experience Transformation to 5G – Densification and HetNet approaches are Laying a foundation for 5G transformation
