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

95% of
Cost of
Production
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:
Busy Hour Mbps
> 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

SP WiFi - Addressing the Challenges
Architecture Issue
SP 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

with EAP-based trust indication
•
WISPR 1.0/802.11i/HS2.0 support for AAA
based roaming
•
PMIPv6 delivering IP persistence to
simple IP clients
•
HS2.0 management object for discovery
and selection of access networks
•
HS2.0: auto login, service advertisement
and online sign-up
•
I-WLAN tunnel over 3rd party untrusted
network to access home operator services
Inter Technology Handover
•
Simple virtual adaptor for basic inter-technology offload
•
DSMIPv6 and DSMIPv6/IPSec for handover between trusted/un-trusted networks
•
IP Flow mobility for static policy based offload
•
Enhanced ANDSF for dynamic policy offload
