These paper select eight countries for describing the experience of cross over points of landline versus
mobile telephone: These countries are USA, Canada, Korea, Hong Kong, Denmark, Netherland, China
and India. We selected these 8 countries to represent the observed diversion in landline to wireless mi-
gration patter in voice telephone across various countries around the world. Using historical data for the
time period 1999 - 2007, we plot the subscribers of landline vs. wireless phone for all these 8 countries
which are shown in Figure-C below.
For each graph shown above, the vertical axis is displaying number of subscribers in million and the
horizontal axis is displaying corresponding time period. The graphs show that in all these countries,
number of wireless subscriptions crossed the number of landline subscriptions by 2006. However, dif-
ferent country reached this cross point at different times between the sample periods 1999-2007. Coun-
tries such as Korea and Hong Kong, being pioneer in telecommunications advancement, have reached
the cross over point in early 2002 whereas other European countries such as Denmark and Netherlands
reached that cross over point during 2005-2006. On the other hand, even though most of the technolo-
gies were available in USA, still the wireless-landline crosses over point took place in lot later than
other many other countries. Same is the scenario observed in Canada. The primary reason behind this
could be that landline infrastructures are so highly developed in these two countries and the landline
penetration rate is so high in each of these countries that phone subscriber's need of using wireless phone
is less in comparison to other countries with poor landline infrastructure. On the other hand, the country
like India and China, the landline penetration was not that high at the time when people around the world
started to use wireless phones due to lack of sufficient landline infrastructure and affordable price for
service. However, in recent past these countries are very rapidly increasing their wireless infrastructure
