Evolution in Broadband Technology and Future of Wireless Broadband - Adoption, Usage, and Global Impact of Broadband Technologies - page 233

landscape. However, since the last actual in the
time series used in the forecasting is year 2008,
the impact of these events is not represented in
the history. This could be a factor in accelerating
the mobile broadband growth in the USA possibly
surpassing subscriptions in Japan and Korea. Thus,
we expect the US mobile BB subscription forecast
of 189M for 2013 to be substantially higher.
It would have been very interesting to study
the current and future trend in behavior of fixed
versus mobile BB adoption for large emerging
developing countries such as India and China.
However, due to limited data, we could not include
them in the analysis.

the diffusion behavior of BB access technology
in different countries around the world. Special
emphasis is given to study the evolving role of
various technologies in developing high speed BB
access to the Internet. Specifically, the focus is
to analyze the dynamics of subscription behavior
of fixed versus mobile BB connections over the
last few years and to predict a directional path of
that future trend.
To understand the dynamics behind the ob-
served difference in penetration rates of Fixed
BB access connections in various countries, we
study selects few countries for which reasonable
time series data are available. Functional data
analysis methodology is then applied to estimate
the velocity and acceleration of BB penetration
rates for those selected countries. Estimated
results show very differing temporal shapes for
the velocity and acceleration curves pointing to
distinct growth spurts associated with different
countries. This phenomenon is influenced by
country specific information policy initiatives and
their underlying structure of demand and supply

CONCLUSION

This chapter begins with the description of pri-
mary characteristics of various platforms of BB
access technology followed by a brief outline of
the benefits of deploying such technology. The
focus of the chapter is to analyze and explain
