Wireless - The Future Of Connecting To The Internet
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!
