Some Facts� Wireline Network subscriber population is shrinking
� Mobile Network will replace Wireline Network
� Mobile phone is convenience, flexibility, feature rich and multi-
functional
� Per head count mobile subscriber vs. per household wireline
subscriber
� US Mobile Subscribers surpassed 250 million in Nov. 2007 (85%
of population)
� Other countries have the same trend
� More people are considering to disconnect the wireline phones

Mobile Network is Evolving …� Just like VOIP is replacing PSTN
� IP/SIP based IMS core is replacing traditional mobile
core
� IP/SIP based IMS core started the fix mobile
convergence era
� Femto access will break down the air interface barrier
� This does not only mean technology advance, but also
business opportunities
� Mobile operator monopoly is collapsing
� Penetrating opportunity for new comers

What are the opportunities all about� IP/SIP based IMS core opened up the core network
signaling and media
� Opportunities for wireline VOIP operators
� Femto access opened up the air interface
� Allows non-mobile operators to reach the mobile users
� Mobile operators still dominate the majority coverage
� However …
� Uncovered spots are opportunities
� less populated rural areas
� Inside the building
� Enterprise may seek for more economical alternate solutions

Build Up Low Cost Mobile Network Using Femto Cell� Femto Cell provides air interface � Base Station
� Broadband Internet connects Femto to IMS core via
FGW �make use of customer’s broadband
� Enterprise leased lines
� Residential broadband (Cable, DSL, FIOS etc.)
� SIP for call signaling
� Interworking to PSTN/PLMN
� Challenges
� Spectrum license & usage (secondary market lease or rental)

How the cash flow comes in …Business Model II� Personal Residential use
� Profit-sharing plan to encourage residential femto subscriber to
provide access to others
� Charge minutes to in-network users
� Charge roaming service fee to out-network users
� Bundle mobile service and VoIP service to attract
subscribers
� Shipping femto devices v.s. the current SIP adaptor
� Users use their mobile handset to gain access
� International call is the killer service
