Wireless Internet access,
sometimes referred to as
a hot spot, is a local
area network (LAN) run
by radio waves rather
than wires. Wireless
Internet access is
broadcast from the
central hub which is a
hard-wired device that
actually brings in the
Internet connection. The
hub, located at the main
computer system or
server, broadcasts Internet
connectivity to clients,
which is basically anyone
within hearing range
who is equipped with a
wireless LAN card.

In the home, a desktop
system setup for wireless
Internet access will
broadcast connectivity
throughout the immediate
area. Any family member
with a laptop or desktop
in another room can
connect wirelessly to the
Internet to share the main
connection. Neighbors
may also be able to
access your wireless
connection, which is why
most wireless LANs are
configured with password
security. In this case, any
machine that wishes to
get wireless Internet
access must first complete
a handshake with the
LAN, in which the
password is requested. If
the proper password is
not supplied, access is
denied. While initial
security technologies were
weak, security protocols
for wireless Internet
access have vastly
improved with Wi Fi
Protected Access (WPA)
and Wi Fi Protected
Access 2 (WPA2) options.

While wireless Internet
access is very convenient
in the home, it is doubly
so in the workplace. A
wired network is not only
very time consuming to
install throughout a
building, it is also very
expensive. Ethernet cables
used to connect client
machines might need to
be routed through walls,
ceilings and floors. In the
past, this disadvantage
was sometimes
overlooked due to the
advantages of greater
security and faster data
transfer speeds through
ethernet cables. However,
these advantages have
been largely mitigated.
Wireless LANs can be
installed in virtually
minutes by nearly anyone,
are extremely inexpensive,
and data transfer rates
rival hard-wired Ethernet
LANs. Furthermore, WPA2
encrypts all traffic on the
LAN, addressing the
problem of
eavesdropping.

One of the most popular
applications for wireless
Internet access is the
public hot spot. Internet
cafs are one example of
places where one can sit
with a laptop and sip
coffee while cruising the
Internet, checking email,
or doing research. Cell
phones and personal
digital assistants (PDAs)
equipped with Web
browsers can also utilize
wireless Internet access
points through public hot
spots. Some localities
provide free wireless
Internet access for
residents and visitors, such
as in the city of Hermosa
Beach, California. Since
wireless LANs use radio
waves that distort over
long distances, the radius
of the signal is limited.
The further from the hub,
the weaker the signal.
Therefore cities that
provide access will cover a
specific area within the
city where people can
park to gain access.

Technology for wireless
LANs is improving
constantly. If designing a
new wireless network, be
sure to get network cards,
a hub and wireless
modem that support the
latest protocols and
security measures. Follow
instructions carefully
when configuring wireless
Internet access and youll
be up and running with a
secure network in no
time!
