Modeling Economics of Indoor Small Cells Source: ABI/Cisco Cost of Production Analysis, assuming CPE offered without cost to consumer and depreciated over 3 years. Macro Networks Mobile Internet Economics – significant incremental cost of production > Ranges from ~$2/GB (3 carrier config) to ~$6/GB (1 carrier config) Indoor offload solutions deliver very low incremental cost of production, similar to fixed Internet economics As Consumption rises, becomes more cost effective to offload traffic: > Compared with a 1-carrrier macro cell, femto delivers improved economics for users with >750 MB/mo consumption > Compared with a 3-carrier macro cell, SP WiFi delivers improved economics for users with >500 MB/mo consumption Busy Hour Mbps

SP WiFi - Addressing the Challenges Architecture IssueSP WiFi Functionality Unlicensed spectrum and interference RF is always a probabilistic environment. Clean air provides unique insight into RF Domain No single entity responsible for SP WiFi architecture definition 3GPP has defined an architecture for “trusted non-3GPP” – baseline for target architecture Challenging to deliver seamless experience PMIPv6 based architecture for seamless mobility across WiFi. IP Persistence can be delivered across inter-technology access Current Bring Your Own (BYO) WiFi approach devalues SP to bit-pipe provider Ability to integrate Consumer CPE into architecture Diverse range of client requirements Able to leverage client functionality whenever available Source: Cisco, 2012.
