  2. 3 What Questions What is the most cost effective manner to handle this traffic? What are the key requirements to handle this traffic? What do we need to take into account in order to maintain a consistent Quality of Experience for the subscribers?

  3. Breakdown in Cost of Production 95% of Cost of Production Source: ABI/Cisco May 2011

  4. Modeling Economics of Indoor Small Cells 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 Source: ABI/Cisco Cost of Production Analysis, assuming CPE offered without cost to consumer and depreciated over 3 years.
