Wireless communication is
among technology’s biggest
contributions to mankind.
Wireless communication involves
the transmission of information
over adistance without help of
wires, cables or any other forms
of electrical conductors. The
transmitted distance can be
anywhere between a few meters
(for example, a television’s
remote control) and thousands of
kilometers (for example, radio
communication).

Common examples of wireless equipment in use today include:
Cellular phones and pagers -- provide connectivity for portable and mobile
applications, both personal and business
Global Positioning System (GPS) -- allows drivers of cars and trucks, captains of boats
and ships, and pilots of aircraft to ascertain their location anywhere on earth
Cordless computer peripherals -- the cordless mouse is a common example; keyboards
and printers can also be linked to a computer via wireless
Cordless telephone sets -- these are limited-range devices, not to be confused with
cell phones
Home-entertainment-system control boxes -- the VCR control and the TV channel
control are the most common examples; some hi-fi sound systems and FM broadcast
receivers also use this technology
Remote garage-door openers -- one of the oldest wireless devices in common use by
consumers; usually operates at radio frequencies
Two-way radios -- this includes Amateur and Citizens Radio Service, as well as
business, marine, and military communications
Baby monitors -- these devices are simplified radio transmitter/receiver units with
limited range
Satellite television -- allows viewers in almost any location to select from hundreds of
channels
Wireless LANs or local area networks -- provide flexibility and reliability for business
computer users

• Advantages
• Wireless communication has the following
advantages:
• Communication has enhanced to convey the
information quickly to the consumers.
• Working professionals can work and access Internet
anywhere and anytime without carrying cables or
wires wherever they go. This also helps to complete
the work anywhere on time and improves the
productivity.
• Doctors, workers and other professionals working in
remote areas can be in touch with medical centers
through wireless communication.
• Urgent situation can be alerted through wireless
communication. The affected regions can be
provided help and support with the help of these
alerts through wireless communication.
• Wireless networks are cheaper to install and
maintain.
• Disadvantages
• The growth of wireless network has enabled us to
use personal devices anywhere and anytime. This
has helped mankind to improve in every field of
life but this has led many threats as well.
• Wireless network has led to many security threats
to mankind. It is very easy for the hackers to grab
the wireless signals that are spread in the air. It is
very important to secure the wireless network so
that the information cannot be exploited by the
unauthorized users. This also increases the risk to
lose information. Strong security protocols must
be created to secure the wireless signals like WPA
and WPA2. Another way to secure the wireless
network is to have wireless intrusion prevention
system

Wireless communication
Wireless communication is the transfer of
information without any physical connection
between the sender and the receiver using the
radio frequency spectrum (air) and hardware,
software, and various technologies to transmit
information.
The wireless communication systems used SIESA
Group are designed with a Data very low cost,
which does not use telephone lines or satellite
coaxial cable. Compared with other similar
technologies requires a considerably lower initial
investment
• In 1973 Martin Cooper introduced the
first radio telephone while working for
Motorola, Cooper pioneering company in
this technology, it is regarded as "the
father of the cell phone." In 1979 the
first commercial system appears in Tokyo
Japan by NTT (Nippon Telegraph &
Telephone Corp.) two years later in the
United States the first commercial analog
cellular system working in the 800 MHz
band also arises. In other countries the
same thing happened and were many
parallel but mutually incompatible
technologies

• The wireless communication systems used SIESA Group
are designed with a Data very low cost, which does not
use telephone lines or satellite coaxial cable. Compared
with other similar technologies requires a considerably
lower initial investment.
• Among the applications of these systems include:
streaming video and audio, remote video surveillance,
extension of LAN (Local Area Network), Internet Services
Broadband, PBX extension (PBXs), voice over IP and
multicast video (video transmission to multiple locations
simultaneously).
• The wireless communication systems SIESA Group offers
are perfect for the project you wish to undertake, since
no other technology can reach remote places and
transmitting information at a higher speed.
