For any cost-conscious Internet user, the
sight of the latest phone bill lying on the
doormat is not a pretty one. Unfortunately, it
really is not something that we can
realistically avoid. After all, we need the
phone companies to gain access to our service
provider, even if we are usually able to get
this access at a local call charge. This state of
affairs is one that has been with us now for a
great deal of time, but will it continue?
Things change, they always do.
A small American company has decided
to kick the phone companies where it hurts, in
the pocket.
The Internet works by transmitting small
chunks or packets of data from place to place,
and so its use is limited to anything that can
be split into small chunks and then
reassembled upon receipt at the other end.
Normal phone calls, on the other hand, are
transmitted using a continuous signal that
permits the people at either end to speak
directly to each other. While we can convert
the packet technique, for use on normal
phone lines, (our modems do this
automatically), it is not possible to transmit
your voice from one end to another using
small chunks of data. Until now that is. Enter
and suddenly the whole face of the Internet
changes not only into something used to e-
mail your friends and flame your enemies,
but also into something you can use to talk to
anyone around the world for the cost of a local
phone call.
New Jersey-based VocalTec is a small
company that has successfully developed a
data compression technique that allows its
users to transmit audio information in packet
form. This means that anyone who owns a
Personal Computer, a sound card, a
microphone and a copy of this software can
physically talk to anyone else (who also owns
VocalTec's Internet Phone software) on the
Internet. A technique that exists to a certain
extent within the technology known as
Voicemail.
However for every silver lining there is a
cloud.
The technology is by no means perfect,
when you want to speak to someone on the
Internet, you are not able to simply have the
phone ring at the other end. Because of the
fact that the information is separated,
transmitted, reformed and then
decompressed, the transmission carries an
awkward time delay. Usually about 1 or 2
seconds. To cut down on the amount of data
that needs to be transmitted, the software
samples at a lower rate, and this tends to
make the voice partially distorted and fuzzy.
You may be wondering why this will worry
the Phone Companies? There has always
been a need to speak to people who are, for
whatever reason, out of earshot, and since the
phones invention we have been paying for the
privilege. Then along came the Internet. Now
many users pay, not only to speak to each
other, but also to wander the information
super highway. Double the business, double
the profit, double the phone companies fun.
Personally I don't think that the bubble
is about to burst though. While it will be
possible to talk to your friends or contacts on
the Internet, send pictures, text and any form
of structured or unstructured data, there is
still a limit to the speed at which this data can
be transmitted. At times the service can be
slow and cluttered, and with more data being
transmitted, surely it can only get worse.
What we really need is to increase our ability
to send large amounts of data over the phone
line, which requires a larger bandwidth. The
only people who can provide that at the
moment are the phone companies. I think
that if a balance isn't reached between the
users of the Internet and it's providers, then
we are unlikely to see any major assistance
from the very people who could make the
Internet into an international solution. After
all, would you willingly provide a service that
could potentially decrease your own business?
