What
is WLAN?
Wireless LAN is a type of local-area network that
uses high-frequency radio waves rather than wires
to communicate between nodes. WLAN is a flexible
data communication system seen as an alternative
to, or an extension of a wired LAN. WLANs transmit
and receive data over the air using electromagnetic
waves, minimizing the need for wired connections.
Thus, WLANs combine data connectivity with user
mobility, and, through simplified configuration,
enable movable LANs. Mobile WLAN users can access
information and network resources as they attend
meetings or when they move to other campus locations.
WLANs is very popular in a number of vertical
markets that include the health-care, manufacturing,
warehousing, retail and academics. According to
Cahners –Instat, the market for wireless
LANs is projected to grow from $1.2 billion in
2000 to more than $5.6 billion in 2005.
Applications scenarios
 |
Handheld WLAN
devices help Doctors to get the status of
their patients instantly, even while they
roam around. |
|
In a meeting,
WLAN handhelds can give real time information,
thus making the decision making process faster. |
|
The cost of
LAN ownership in a dynamic environment is
minimized as the overhead of moves, adds,
and changes LAN are reduced. |
|
In educational
or training institutes, WLAN devices help
in information exchange and learning. |
|
Warehouse owners use wireless
LANs to exchange information with central
databases and increase their productivity. |
WLAN FAQ's
What is WLAN?
WLAN is a communication system that reduces the
need for wired connection. It is a data communication
system seen as an alternative to, or an extension
of a wired LAN.
How big is the Wireless LAN
market?
According to Cahners –Instat, the market
for wireless LANs is projected to grow from $1.2
billion in 2000 to more than $5.6 billion in 2005.
Another estimate from Frost and Sullivan forecasts
that manufacturers' revenue in the total worldwide
wireless LAN industry will approach $884.0 million
by the year 2002.
Will Bluetooth and WLAN interfere
with each other?
Although both 802.11b and Bluetooth operate in
2.4 GHz ISM band, yet the probability of interference
is low. Since Bluetooth devices use Frequency
Hopping and most WLANs use Direct Sequence Spreading
techniques so each appears as background noise
to the other and thus does not cause any performance
issue.
What is the transmission range
for Wireless LAN products?
The radius of coverage for typical WLAN systems
varies up to 500 feet (164 meters) depending on
the number and types of obstacles encountered.
Coverage can be extended, and freedom of mobility
and roaming can be provided for a greater area
through the use of multiple access points.
What is an access point?
An Access Point connects wired and wireless networks
together. It enables the sending and receiving
of data between wireless clients and the wired
network. Users can roam between access points
and still be connected to the network. Access
points are required for network access but not
for peer-to-peer connections.
What are WECA and Wi-Fi?
The Wireless Ethernet Compatibility Alliance (WECA)
is a non-profit organization formed in 1999. Its
mission is to certify interoperability of Wi-Fi
(IEEE 802.11b) WLAN products and to promote Wi-Fi
as the standard for wireless LAN deployment. Wi-Fi,
or ‘Wireless Fidelity’, is the trademarked
name that WECA uses to signify WLAN product interoperability.
