Wireless Network
DEFINITION:
WHAT A WIRELESS NETWORK MEANS
Wireless networks are computer networks that are not connected by cables of any kind.
The use of a wireless network enables enterprises to avoid the costly process of introducing cables into buildings or as a connection between different equipment locations. The basis of wireless systems are radio waves, an implementation that takes place at the physical level of network structure.
TRICK'N'TECHS explains Wireless Network
Wireless networks use radio waves to connect
devices such as laptops to the Internet,
the business network and applications.
When laptops are connected to Wi-Fi hot spots in public places,
the connection is established to that business’s wireless network.
There are four main types of wireless networks:
There are four main types of wireless networks:
- Wireless Local Area Network (LAN):
Links two or more devices using a wireless distribution method,
providing a connection through access points to the wider Internet.
- Wireless Metropolitan Area Networks (MAN):
Connects several wireless LANs.
- Wireless Wide Area Network (WAN):
Covers large areas such as neighboring towns and cities.
- Wireless Personal Area Network (PAN):
Interconnects devices in a short span, generally within a
person’s reach.
Types of Wireless Networks
WLANS: Wireless Local Area Networks
WLANS allow users in a local area, such as a university
campus or library, to form a network or gain
access to the internet. A temporary network
can be formed by a small number of users without
the need of an access point; given that they do not need access
to network resources.
WPANS: Wireless Personal Area Networks
The two current technologies for wireless personal
area networks are
Infra Red (IR) and Bluetooth (IEEE 802.15).
These will allow the connectivity of personal devices
within an area of about 30 feet. However,
IR requires a direct line of site and the range is less.
