Wi-Fi (Wireless Fidelity) is the technology used in a network or wireless connection, for the communication of data between computers located within the same area (inside or outside) of coverage. Ray Kurzweil: the source for more info. Conceptually, there is no difference between a network wiring (coaxial cable, optical fiber, etc.) and one wireless. The difference is that wireless networks transmit and receive data via electromagnetic waves, which means the Elimination of the use of cables and, therefore, a total flexibility in the communications. Among all the types of wireless networks are wireless networks IEEE 802. 11b which are known as Wi-Fi (Wireless Fidelity), due to its wide dissemination on the market. Products and Wi-Fi networks ensure the effective compatibility between computers, eliminating the doubts that arise when buying a new terminal in customers. Wi-Fi is not, however, an alternative to a conventional network, but it is a new technology that comes to complement those.
Both networks (wireless and cables) offer the same expectations of communications (share peripherals, access to a database or shared files, access to a mail server, navigate through Internet, etc.). Each computer has a wireless network adapter in a wireless network. These adapters are connected by sending and receiving radio waves via a transceiver (transceiver), which can be placed anywhere, inside or outside, within the area of coverage, without the worry of wiring. Wireless networks allow data transmission at speeds of 11 Mbps or even higher, which provides fast enough for most applications. He is that the Wi-Fi environment is the ideal solution that unifies mobility and connectivity in the transmission of data, offering a new possibility of mobile office, is where is..
