It's not exactly breaking news that our world is becoming
increasingly wireless. Many of our daily activities that
once needed a wired connection can now be done wirelessly!
Laptop Battery The cell phone craze was probably the first revolution
that
seemingly happened overnight. The convenience of being
constantly connected or plugged in to the your
business,
friends, or family was an undeniable need that was quickly
met. For many people it has become a necessary in their
daily lives.
While most laptops today feature integrated wireless connectivity, that is, they already have everything they need to connect to a wireless connection, some do require the use of a plug in card. standard PCMCIA (Personal Computer Memory Card International Association) slots on your laptop (the PCMCIA slots are the little doors on the side of your laptop which are about the width of a mobile phone and around half a centimetre thick). Once the card is plugged in and set up (youa ll need to install appropriate driver software), youa ll be able to connect to a wireless network.
Thinkpad Wireless computers, notebooks or laptops may just be the
second
wave in our struggle to becoming a totally wireless world.
The
ability to be constantly connected to your
business and/or loved
ones is revolutionizing the way we use computers and the
Internet.

Microsoft The ultraportable, versatile little notebook computer, will no
doubt
play a major leading role in our wireless struggle to be
constantly
connected. It's the 'portability' of the notebook or laptop
computer that holds the most appeal and is its major selling
point. And its popularity is growing.
Home wireless routers allow you to connect your home computers together into a network. If you want to use your router as a firewall also, in firewall. Otherwise, you can purchase a firewall separately. Wireless network routers will allow you to connect computers, notebook computers, PDAs and printers without wires. They are also useful for connecting laptops to the Internet and other networks, such as at work or at home.
Laptop Computers It is estimated that over 42 million computer notebooks
will be produced this year in 2005. The
market for laptop and
notebook computers is growing at a rate of 20% each year
according to Taiwanese notebook makers. And they should
know - they make 70% of these notebooks or their components
for such major players as Dell, Hewlett-Packard and Gateway.
Use this as your 'gateway' to connect multiple computers, including laptops, to your wireless network.
Laptop Computer But it's the portability and wireless communication these
devices
offer that's increasing their popularity among most users.
Broadband data service provided by your mobile wireless phone carrier is another option for high–speed Internet access. Broadband data service is available for users with wireless mobile smart phones. It is also available for a notebook computer, using a broadband data card provided by the wireless service provider that connects via a USB port or card slot). The broadband data service connects your computer to the nearest wireless mobile tower, enabling you to use it while the RV is parked or moving.
Desktop Computer Just how is this wireless communication accomplished by
the
notebook or laptop you ask?
Notebooks Wireless notebooks uses three major wireless data standards
in
order to transfer data. The one that is probably most common
is
802.11b, also called Wi-Fi which stands for Wireless Fidelity.
Lenovo Wi-Fi or 802.11b transfers data wirelessly at a maximum rate
of
11Mbps for up to 150 feet. It uses the 2.4GHz radio spectrum
and
although it says 11Mbps, you will probably only get around
4-6Mbps
in actual use. But this is enough bandwidth for high speed
Internet, gaming and most file transfers.
Hard Drive The 802.11a is another standard that uses the 5GHz radio
spectrum,
so it has 8 channels available instead of only 3 that's available
with
802.11b. The 'a' version also permits a larger transfer, at a
maximum
of 54Mbps.
Travelstar The other standard, 802.11g, is a hybrid of 'A' and 'B' - its
also
capable of 54Mbps but it uses the 2.4 GHz spectrum and is
compatible
with 802.11b devices. Some notebooks like the Fujitsu LifeBook
N6010,
have a tri-mode 802.11a/b/g wireless system that uses all three
forms!
Gateway The next technology in Wireless Communication is 3G EV-DO!
Sounds
like one of those funny robots from Starwars - but it stands
for
evolution-data optimized. This new technology will change how
we
view and use the world wide web.
Laptop Parts Verizon Wireless 3G EV-DO began commercial operations in Oct.
of
2003 and is now expanding to over 125 million US consumers by the
end
of 2005. With download speeds of 400 to 700 kbps and bursts up to
2 Mbps,
3G has really given us wireless Internet this time. It has or
will
turn the Internet into a truly wireless system that's devoid of
any
cables or lines. It will be everywhere - no space within our
biosphere
will be without the Internet very soon.
Software Of course, it should be kept in mind, that any group of
computers can be
made wireless by using a wireless router and a wireless network
adaptor
for each computer. Also, many notebooks and computers come with
a
Bluetooth module, which allows for wireless communication
between
any sort of electronic devices - from cell phones to computer
to
stereos to headphones.
Hard Drives However, if you're setting up a wireless network or if you're
using
your wireless notebook or laptop at hotels and airports -
security
will be a concern. Anyone, within distance possessing the right
equipment
and a little ingenuity may get access to this wireless system. For
major
corporations or the lowly homeowner; safeguards need to be taken
to
prevent unwanted visitors from interrupting your peaceful
wireless
universe.
Electronics There are usually two basic methods of securing wireless
networks, WEP
and MAC address filtering. The MAC (Media Access Control) is the
physical
address or unique hardware identifier given to each device in the
network.
Then you manually enter a list of addresses that can use or access
your
wireless network.
Canon The other filtering process is more secure, WEP or Wireless
Encryption
Protocol requires a shared key between the users and then using
this key to
encrypt and de-encrypt data that's transmitted between your
network users.
Desktop Pc Many major hotel chains and other businesses are now offering
'Wi-Fi'
services as an added convenience to their patrons. These 'hot
spots' are
popping up everywhere, even at some gas stations. You may need to
sign in or get
a password or key to access these services.
Desktop Computers But like your cell phone conversations, any radio transfer
or
transmission will not be as secure as a wired connection. Keep
this in
mind if privacy is a major concern for you. But don't let it stop
you
from enjoying the convenience, portability and practicality of
your
wireless notebook or laptop.
Think Pad It's a wireless world after all.
