Wireless - The Future Of Connecting To The
Internet
Kevin Erickson

What is WiFi?

Wifi or Wireless Fidelity, allows you to connect to the
internet from virtually anywhere at speeds of up to 54Mbps.
WiFi enabled computers and handsets use radio technologies
based on the IEEE 802.11 standard to send and receive data
anywhere within the range of a base station. Wireless is a
technology that's inexpensive, easy to use, and practical and
yet... it's a technology that's still very young. Here's a
quick look at what the future could hold for wireless.

The Radio and the Phone

Wireless networks will always win over wired ones, if for no
other reason, simply because it is much cheaper for signals to
travel through the air than it is to install and maintain
wires. For example... consider that telephones were originally
used for sending and receiving news reports. When radio was
invented, this stopped almost overnight - why bother going to
all that expense when it's free 'over the air'? The same
principle applies to computer networking.

Imagine having a choice between a wired Internet connection and
a wireless one. The only reason to choose a wired connection
would be cost because currently it's cheaper? However, that
will change soon. Wireless is also easier. Once the cost gap
closes, if given the opportunity, there's no logical reason why
anyone wouldn't switch to a wireless connection.

WiMAX

WiMAX is the next generation of wireless. It will use a
standard called 802.16. The current standard is 802.11. It's
still a work in progress, but the possibilities are exciting.

WiMAX stands for Worldwide Interoperability for Microwave
Access and is designed to complement existing wireless
equipment... rather than replace it. The big advantage of WiMAX
is that it greatly increases range. Rather than being measured
in square meters, which is how the current standard is measured
in, WiMAX ranges will be measured in square kilometers. Some
estimates say the best WiMAX stations will be able to transmit
up to 50 kilometers or about 30 miles!

Clearly, this opens an incredibly wide range of possibilities.
Wireless access would move from LANs (Local Area Networks) to
MANs: (Metropolitan Area Networks) covering a whole town or
city with wireless access. The question would no longer be if
you could connect via wireless, but what WiMAX network you
wanted to connect too.

Other benefits of WiMAX include speed of up to 70Mbps (almost
10 MB per second) and better security. Imagine a future where
ordering Internet access is as simple as connecting your
existing wireless equipment to the network, opening your web
browser and buying a low cost subscription. That's it - done.
No more access points, no more routers, no more
configuration... just wireless Internet, anywhere and
everywhere at broadband speeds. WiMAX is in the process of
taking the world by storm.

For the latest news on WiMAX visit the WiMAX Forum (a
non-profit industry group set up to promote WiMAX) at
http://www.wimaxforum.org. WiMAX has been in development since
2001 and the first WiMAX equipment is expected to hit the
market in late 2005 or early 2006.

What is Bluetooth?

Bluetooth is a new standard for short range radio connectivity.
It is the new and promising field in the wireless communications
standardization activities, which will profoundly affect the
operation and applications of electronic gadgets of the future.
The most obvious purpose of Bluetooth technology is to replace
USB and it's designed to eventually replace almost every wire
there is… except power cables. What does that mean? It means
that someday your TV could be connecting to your DVD player via
Bluetooth or your speakers could connect to your radio with it,
and so on and so on.

As you get older, expect to see fewer and fewer wires. I know…
people said the same thing about paper but it turns out that
people like paper and don't want a 'paperless society'. On the
other hand, how many people do you know who have cable or wire
fetish? The biggest remaining article is reliable wireless
power. When they figure out how to provide reliable wireless
power (i.e. better batteries)… look out because the flood gates
will really open up.

A Simpler Life

Convenience... the first benefit of wireless technology that
comes to my mind. Wires have so many flaws, especially when
they go long distances and the overall wireless project is to
remove the vast majority of them from our lives. Of course,
another nice benefit will be cost because once wireless if up
and going full-bore it will cost less than wire based
transmission.

My prediction... within 10 years, wireless access will be
making everyone's life much easier and it will be the norm. The
future is wireless!
