Phases of WiFi Offload


WiFi has come in from the cold; it is becoming part of mainstream
operator
-
thinking


WiFi integration is user
-

and services
-
led; it is not primarily about
cost reduction


Ultimately WiFi will be considered a trusted access network on a
par with the 2G/3G/LTE RAN

How to decide
which network to
attach to?

How to integrate
with the core
network?


Device is best
-
placed to
understand local radio
conditions; but




May not know which APs
it has permission to access




May not know the
prevailing performance of
each access type


Some services *only* available
through the operator core



Core network not aware of radio
access conditions



Will ANDSF, policy & NGHI help
bridge these gaps?

Adaptability of WiFi creates diversity of implementation


Managed Hotspots are the focus of attention


Are Hotspots enough to make a
real

difference?



Poll Question #1



How important is it to your choice of mobile provider that your
smartphone tariff includes bundled WiFi access?



Not important at all; I prefer WiFi to be separate


Valuable at the margins, but not especially important


An important factor, but not decisive


Very important; a “must
-
have” feature

Poll Question #2


What is the biggest barrier to integrating WiFi into mobile operator
service portfolios?



It is hard to get a large enough WiFi footprint to make a real
difference to most users


It is hard to get a consistent device implementation and so
difficult to market and support


The back
-
end tools to mange provisioning and billing of devices
are not mature enough

Summary


WiFi is now a core part of the smartphone user experience



Operators are evaluating how to attract and retain customers
through integration of WiFi in their service portfolios and networks



Managed hotspots are the most viable starting point because of the
ability to influence service quality and monetize usage



The Next
-
Generation Hotspot Initiative makes an important
contribution towards making WiFi a carrier
-
class technology



Potential for WiFi to be considered a trusted access network on a
par with 3G or LTE
