Since the dawn of humanity, a key issue with respect to development and progress, has been the need for communication between each other, present throughout history.
In recent years, new technology achievements have been the emergence of computers, telephone, cell lines, wired and wireless networks and satellite.
The main principle of communication is via speech on the relationship between sender, message and receiver. But technology today should not only refer to the voice, but should try to cover a wider gamma of applications, be it data transmission. Given this need is emerging computer networks like the intranet, extranet and internet.
Concerning the exchange of voice and data need to be connected to the world via the Internet is essential, where some problems arise concerning the implementation of wired networks because the transportation of equipment is necessary either within a local and within an office.
By presenting this need it became part of a group of larger study, from wireless networks, transferring data via infrared, as well as the application of satellite networks. They have failed to meet this need making the connection of users in different parts of the world. The application of wireless technology , is having a boom in transmission speeds , but not compete with the use of wired networks or the use of fiber optics , however satisfactorily meet the need of users movement . Let us start with the definition of wireless, this term refers to the use of wireless technology which allows you to connect multiple computers together.
Thus it has been becoming one focus of study for data transmission issues, gaining interest in places where it is not possible to install wired networks.
The use of this wireless technology allows you to leave forgotten cables without the need to stop a connection, disappearing limitations of space and time, giving the impression that an office can be located anywhere in the world.
One application of this case could be the relationship that is established between employees located in a place other than his workplace and becoming the largest company network flexibility. The devices are connected to other wireless devices to provide dynamic workers a strategy more effectively and with fewer complications job.
The desktop applications also make the network load is lighter.
Using wireless technology determines that the company increase productivity and efficiency, thus the employee is exclusively dedicated to what he does best, avoiding the disadvantages of a technological nature.
