Xpert wireless family of products will allow you to securely access the data you
want, when and where you want it. You will be able to enjoy the freedom that wireless
networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits
and receives data with radio signals instead of wires. Wireless LANs are used
increasingly in both home and office environments, and public areas such as airports,
coffee shops and universities. Innovative ways to utilize WLAN technology are helping
people to work and communicate more efficiently. Increased mobility and the absence
of cabling and other fixed infrastructure have proven to be beneficial for many users.
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 Access Point (AP) 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 are easy to set up, manage, change and
relocate. Networks that frequently change can benefit from WLANs ease of
implementation. WLANs can operate in locations where installation of wiring may be
impractical.
Installation and Network Expansion
- Installing a WLAN system can be fast and
easy and can eliminate the need to pull cable through walls and ceilings. Wireless
technology allows the network to go where wires cannot go - even outside the home or
office.
Inexpensive Solution
– Wireless network devices are as competitively priced as
conventional Ethernet network devices.
Scalability
– WLANs can be configured in a variety of ways to meet the needs of
specific applications and installations. 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.
