Wi-Fi offload impact on revenue or Subscriber experience
• The carrier WiFi and small cells infrastructure market will grow
at CAGR of 37% over next five years, accounting for nearly USD
9 Billion in revenues by the end of 2017.
• The carrier WiFi market alone is expected to account for nearly
USD 5 Billion in global revenues worldwide by 2017, growing at
a CAGR of 33 % between 2012 and 2017.
• The small cells market is expected to account for nearly USD 4
Billion in global revenues worldwide by 2017, growing at a
CAGR of nearly 40 % between 2012 and 2017
• The continued demand for mobile broadband services will play
a critical role in maintaining the Carrier WiFi and small cell
market's growth, amid a growing demand of convergent,
intelligent and vendor agnostic small cell platforms by Carriers.
• Fixed line carriers are capitalizing on their infrastructure
investments to offer Small Cells as a Service (SCaaS). Mind
Commerce expects Fixed line carriers to form an integral part of
the industry's value chain representing as much as 20% of the
revenue share.

11. SOLUTION : WIFI-LTE INTEGRATION ON SMALL
CELL
 Integration of Wi-Fi n/w to LTE n/w based on LIPA
method. Wi-Fi as associated data network.
 Where data plane could be distributed over two
different LIPA n/w. Though the control and mobility
is maintained wrt LTE n/w only.
 UE would be using Wi-Fi and LTE radio
simultaneously.
 UE capability for multiple PDP context. For Normal
PDP as well as for LIPA PDP context.
 Traffic based offloading and homogeneous policy
management.

16. WHAT ? THE SOLUTION ADDRESSES
• Number of user coverage, LTE small cell back-
off, data traffic calculation.
• WiFi Hotspot 2.0/Passpoint with SIM based
authentication to improve user experience
 How to handle the amount of traffic to be
offloaded by WiFi network?.
• WiFi network traffic management and seamless
integration with 4G network.
• Network coordination and interference
management with macro networks.
• Network discovery and Selection of backhaul
network and other processes in network
management.
• Security , authentication, billing, policy and how
to reduce the handoff latency between LTE and
WiFi.
• Need for end user satisfaction, reduce
infrastructure investments and operating
expenses.
• To Evaluate the cost and benefit of using WiFi,
Femto cells, pico cells to reduce network
congestion and improve network coverage per
cell.
• Wi-Fi offloading data is in market for long time, but due to
mobile data traffic it is hot topic now.
• Small cells are the competitor for Wi-Fi offload solution in
long run, but in current scenario it is more complicated
(because of RAN, business models, management tools)
and cost over run solution.
• Now a days most of equipment vendors provide Wi-Fi
built-in small cell modules.
• seamless Wi-Fi offload is the ideal remedy to both
problems as carriers can offload 50% or more of their
traffic to Wi-Fi, and at the same time offer high-value,
convenient new services to stand out in the market. -
Aptilo Network
• Around 60 % of mobile data will be offloaded to Wi-Fi ,
with integrated Wi-Fi solutions– juniper research
• Femtocell and Wi-Fi network integration for indoor mobile
data traffic with power saving feature.
• To meet rising demands, operators going towards to
install more advanced accessing technologies, more
base station/hotspot and combination of network
technologies
• 24% of all traffic generated from smartphones, laptops,
games consoles and e-Readers which have an active
3G/4G connection will be onloaded to the cellular
network by 2016. - Juniper Research

17. ISSUES AND CHALLENGES
 Availability of LIPA connectivity to UE, as no
standard procedure available. 3GPP define the
LIPA requirements TR23.829 V10.
 Making core aware of local network so that it can
provide UE with LIPA related info.
 ANDSF (TS 23.402) functionality is being explored to
help in this regards.
 Provisioning of extended GTP tunnels through NAS
procedures is being explored.
 Mobile may be required of having Client software
with GTP-U.
