Wireless Networks
                     WIRELESS NETWORKS
INTRODUCTION
A wireless network refers to a 
computer network that makes use of 
Radio Frequency (RF) connections 
between nodes in the network. 
Wireless networks are a popular 
solution for homes, businesses, and 
telecommunications networks.

WIRELESS LAN
Wireless LAN (WLAN) technology 
provides internet access within a 
building or a limited outdoor area. 
First used within offices and homes, 
WLAN technology is now also used in 
stores and restaurants.

WIRELESS MAN
Wireless metropolitan area networks 
have been installed in cities 
worldwide to provide access for 
people outside an office or home 
network. These networks cover a 
wider area than office or home 
networks, but the principles are the 
same.

WIRELESS PAN
Wireless personal area networks 
cover a very limited area typically a 
maximum of 100 meters for most 
applications using protocols like 
Bluetooth and Zigbee. Bluetooth 
enables hands-free phone calls, 
connects a phone to earpieces or 
transmits signals between smart 
devices.

WIRELESS WAN
Wireless WANs use cellular 
technology to provide access outside 
the range of a wireless LAN or 
metropolitan network. These 
networks enable users to make 
phone calls to others.

5G INTRODUCES 
WIRELESS OPTIONS
The advent of 5G has suggested a 
possible fifth form of wireless, larger 
than a WAN but smaller than most 
MANs. Ongoing work is investigating 
a possibly less expensive alternative 
to cable: 5G to the home or office.

PRODUCTIVITY
Wireless access to the Internet and 
to your company's key applications 
and resources helps your staff get 
the job done and encourages 
collaboration.

EXPANDABILITY
You can easily expand wireless 
networks with existing equipment, 
whereas a wired network might 
require additional wiring.

REDUCED COST
Because wireless networks eliminate 
or reduce wiring expenses, they can 
cost less to operate than wired 
networks.
