The End of Cell Phones?
The past few years has seen VoIP usage
increase exponentially with the main draw being cheaper call rates
especially for international callers. VoIP users are now numbered in
the millions; some predictions indicate that the US alone will have
over 12 million VoIP users by 2009. The majority of these users are
taking advantage of broadband to provide their VoIP service with
either an ATA or VoIP phone. The key here is the broadband enabling
technology - without broadband VoIP would not provide a viable
alternative to the traditional telephone network. Eventually
(although this is still several years away) VoIP will completely
replaced the traditional PSTN.
Fairly recently, a new trend has
appeared - publicly available WiFi. Many shops, cafés,
airports and public buildings are providing WiFi networks for the
convenience of their customers. This allows people with WiFi enabled
laptops and PDA's to browse the web or email while they are having a
coffee, or even compare shop prices with an on-line price (not sure
this is so good for the shops!). In some cities the WiFi networks
mesh together and provide internet connectivity over very large
areas. This is not restricted to city centres either; there are
plans for some rural
communities without high speed internet access to be provided
with WiFi as an alternative to installing a lot of expensive cabling!
So what does this mean? In the same
way that broadband enables users to replace their traditional
telephone service with a VoIP one, public WiFi could allow users to
replace their cell phone with a VoIP enabled PDA. There are lots of
WiFi enabled PDAs out there that can easily provide voice services at
massively discounted rates when compared with the cell phone network.
A call using a cell phone typically costs many times that of a
comparable call from a land line, which again typically costs more
than a VoIP call. As an extra bonus, users with a VoIP enabled PDA
that use a VoIP service at home could use the same service for their
VoIP enabled PDA and have the same incoming number for calls at home
and while on the move. I doubt if this will happen overnight, but as
WiFi coverage increases, expect to see mobile phone rates decrease!!
