Wireless Network At a glance
A wireless LAN or WLAN is a wireless local area
network that uses radio waves as its carrier: the last link with
the users is wireless, to give a network connection to all users
in a building or campus. The backbone network usually uses cables.
WLAN is expected to be an important form of connection in many
business areas. The market is expected to grow as the benefits of
WLAN are recognized. Frost and Sullivan estimate the WLAN market
to have been 0.3 billion US dollars in 1998 and 1.6 billion
dollars in 2005. So far WLANs have been installed primarily in
warehouses and resellers, but are recently being installed in
various kinds of schools. Large future markets are estimated to be
in health care, educational institutes and corporate offices. In
the business environment, meeting places, public areas and side
offices would be ideal for WLAN. WLAN is an alternative to cabled
LAN in places where cabling is difficult or impossible. Such
places could be old protected buildings or classrooms. WLAN
installations are also cheap because they consist only of the
access points and backbone network ins
Early development included industry-specific solutions and proprietary protocols, but at the end of the 1990s these were replaced by standards, primarily the various versions of IEEE 802.11 (Wi-Fi) (see separate articles) and HomeRF (2 Mbit/s, intended for home use). An alternative ATM-like 5 GHz standardized technology, HIPERLAN, has so far not succeeded in the market and might never do so. There are two possible types of infrastructure: Peer-to-peer or ad-hoc mode and the so called infrastructure mode. Peer-to-peer: This mode is a method for wireless devices to directly communicate with each other. Operating in ad-hoc mode allows wireless devices within range of each other to discover and communicate in peer-to-peer fashion without involving central access points. Infrastructure mode: This mode wireless networking bridges a wireless network to a wired Ethernet network. Infrastructure mode wireless also supports central connection points for WLAN clients. A wireless access point is required for infrastructure mode wireless networking, which serves as the central WLAN communication station.
Access Point ("Bridge")
Wireless Network Adapter
A Wireless network adapter is the device that usually connects to your computer or laptop. It is the linking point between your local Ethernet Card and the Network's Access point . |
