A wireless network is a communication network where cables are eliminated and data transmission is carried out using waves. There are different types of networks that can be framed within this definition, networks that can be used for the provision of the Internet, for the provision of mobile phone services or simply for strictly personal use. Wireless networks are today an aspect of technology that has certainly contributed a lot to changing the way in which communications are developed within society and it is believed that they still have many more possibilities to offer, significantly increasing the amount of data that can to transmit.
Characteristics and relevance
The main function of a wireless network It is to establish communication between different devices without using cables. This circumstance has a great relevance from the point of view of costs, saving a great amount of money for the cables that will be put aside. However, the main problem that these types of networks have is that of security, a circumstance that has made it necessary to develop specific standards to keep them free from any attack, any theft of information that may occur; In the case of the Internet, these security systems are called WPA, WP2 and WEP.
Waves that transmit information
The waves that can be used to trace a wireless network they are varied. In the first case we have radio waves, waves that are oriented in all directions and that remain at relatively low frequencies. Then we have the so-called satellite microwaves, waves that are emitted from the Earth towards an orbiting satellite and from there they are sent back down in an amplified way. Finally, there are so-called terrestrial microwaves, waves that require parabolic antennas that must be aligned to allow transmission.
Revolution in constant development
Wireless networks have enabled a true revolution when it comes to telecommunications. In effect, they have meant real progress to the extent that they enable us to be easily connected in any populated place, a place where there is generally the necessary coverage. On the other hand, as has already been made clear, this process is carried out by significantly reducing costs by neglecting the laying of cables. Further improvements in wireless network technology are expected in the future, improvements that will increase its efficiency.
