Wireless Basics
Wireless users can use the same applications they use on a wired network.
Wireless adapter cards used on laptop and desktop systems support the same
protocols as Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile network devices to
link to a conventional Ethernet LAN in order to use servers, printers, or an Internet
connection supplied through the wired LAN. A Wireless Router is a device used
to provide this link.
People use wireless LAN technology for many different purposes:
Mobility
- Productivity increases when people have access to data in any
location within the operating range of the WLAN. Management decisions based
on real-time information can significantly improve worker efficiency.
Low Implementation Costs
– WLANs (Wireless Local Area Networks) are
easy to set up, manage, change, and relocate. Networks that frequently change,
both physically and logically, can benefit from WLANs ease of implementation.
WLANs can operate in locations where installation of wiring may be impractical.
Installation Speed and Simplicity
- Installing a wireless LAN system can
be fast, easy, and can eliminate the need to pull cable through walls and ceilings.
Network Expansion
- Wireless technology allows the network to go where
wires cannot.
Scalability
– Wireless Local Area Networks (WLANs) can be configured in a
variety of topologies to meet the needs of specific applications or existing
infrastructure. Configurations are easily changed and range from peer-to-peer
networks suitable for a small number of users to larger infrastructure networks
to accommodate hundreds or thousands of users, depending on the number
of wireless devices deployed.
