The 1999 renamed Wi-Fi Alliance was previously incorporated under the name WECA (Wireless Ethernet Compatibility Alliance) and includes nearly about 300 companies. The organization deals with products from different manufacturers which are certified based on IEEE 802.11-standards, so that the use of different wireless devices works and can be ensured. This arose from the idea that a needed standard has not been fully implemented. The result was often an incompatibility between products from different manufacturers.
For this reason the Wi-Fi Alliance is testing the corresponding components according to their own guidelines. The products, which pass the examination, will receive the so-called Wi-Fi Certificate and can bear therefore the Wi-Fi Logo.
The so-called Ethernet is a series of frame-based computer networks for local networks. The name is derived from the term ether and declares therefore its name. In this case it defines a series of cables, signal systems, the common format and addressing. If someone will add the term of wireless, it means, that there is a network, which works without wire, – which will mean “wireless”. The networking within an office or the inside of a house works via a wireless connection. The benefit remains the same.
A wireless connection is useful for the reason, that the connection of the computer with cables in different locations is unnecessary.
The effort for a connection with the appropriate cables is not necessary. The access, the connection will be realized by a router, which can be reached by the different locations. By the Wi-Fi Certification, which has been mentioned elsewhere in the text above, it is ensured, that the various devices and products used on different PCs are compatible. In this way, a wireless connection, – will mean the Wireless Ethernet, can work without difficulties.
