WIRELESS TECHNOLOGY
[attachment=55467]
INTRODUCTION
Wireless is a term used to describe communications in which electromagnetic waves are used for communication purpose
The first wireless transmitters went on the air in the early 20th century using radiotelegraphy (Morse code). Later, as modulation made it possible to transmit voices and music via wireless
HISTORY
The theory of electromagnetic waves by Heinrich Hertz in 1888 Theory of electromagnetic waves were predicted from the research of James Clerk Maxwell Hertz demonstrated that electromagnetic waves and they were able to be received by an experimental apparatus
Difference between wired and wireless technology
Wireless networking has predominantly become more popular over the past few years, with advancements in technology, wireless speeds are getting closer to matching those of wired and many homes and businesses are implementing them into their network.
While wireless certainly offer flexibility and convenience there are also many other important factors to consider when using them in place of wired networks.
SPEED
The networking of the wired networks are more faster as compared to other types of wireless networking devices because they are able to provide the speed of more then 1000 Mbps.
INSTALLATION
Wired, ethernet cable must be on each computer to another computer or a central device. This often causes complications because of the length of cable required and necessary arrangements to wire the room neat.
Wireless, can be configured in 2 ways
Ad hoc networks
Infrastructure mode
Both ad hoc and infrastructure mode needs a Network adapter called WLAN cards.
RELIABILITY
Due to there being no physical medium, data has to transfer through the air and must pass through any surface in its path.
This means that signals can get blocked and deflected and this means your connection can suffer or even drop.
Wired network fails very rarely and provide good speed and performance
MOBILITY
In wired technology it cannot provide mobile network.
Difficult to lay down the cables and it looks very messy when install outside.
In wireless technology it is not very much reliable only best for mobile devices such as Laptops.
Not faster as compared to wired devices
CONCLUSION:
Use of Wireless technology is rapidly increasing an playing an important role in life of people throught the world very large number of people are replying on the technology directly or indirectly.
