Answer 1:
In order to communicate (and surfing the web is
just that) without using a cable, you need both
a transmitter and a receiver.
>Sure, it's possible. A television,
however, is only a receiver, so you would need a
transmitter as well.
Communication via light might also be slower,
since it would have to reflect light off of
satellites. In short, there are several technical
difficulties. However, I would wager a guess that
the internet of the future will be very much like
that, though I would not care to guess when. |
Answer 2:
This is already starting to happen - I am
using it. I have a telescope at the White
Mountain Research Station in the
Inyo-White Mountains in eastern California. I am
able to control my telescope from Santa Barbara
using the internet even though there are no phone
lines or cables going up to the station,which is
at about 12500 ft. elevation.
We have two methods of wireless
internet. The first one is by using a
dish to send signals to (and receive signals
from) a satellite which communicates with some
base station somewhere that is connected to
the wired internet. The other method uses
radios that send signals from a station in
Bishop, CA to an antenna on the peak of White
Mountain (elevation 14246 ft.) which then
transmits to another antenna where my telescope
is. The radio method is much faster than the
satellite method but we are still working out
reliability issues so it is nice to have both in
case one goes down for some reason.
In addition, there are ways of setting
up local wireless networks in small areas - like
inside buildings. Also, I believe some cell
phones have the equivalent of wireless internet
access. I think there are probably a lot of
issues to be worked out before we get to the point
where you could have some sort of antenna on your
PC that would allow you to hook up to the internet
wirelessly no matter where you are but it is
possible.

Answer 3:
Yes, that is indeed possible. In fact,
current cell phones use electromagnetic
waves to allow people to talk and access the
internet in much the same way you are imagining.
The only problem is cell phones don't have very
fast connections right now. The current speed is
around 10 Kbps (Kilobits per second)which is
slower than the speeds people can obtain from
regular modems which go at about 56
Kbps and considerably slower than cable modems and
DSL. However,there are new wireless technologies
such as 4G which are being developed and will
allow for speeds of up to 10 Mbps (Megabits per
second)! Thanks for your question!
