The wireless standard that is used for local area networking and Internet access, Wi-Fi ostensibly stands for Wireless Fidelity. Using radio frequency technology, Wi-Fi routers enable computers or laptops equipped with Wi-Fi adapter cards to communicate with each other or access an Internet access point without the need to be physically connected to a cable. There are several Wi-Fi standards and Wi-Fi equipment are rated against these standards. The earlier standards were 802.11a and 802.11b, the current standard is 802.11g. Standards a and g have a maximum throughput of 54 Mbps and an active radius of about 30-35 meters indoors. Thus, if you would like to browse the Net while on your balcony, get yourself a wireless router; if you are using a laptop, chances are it comes Wi-Fi enabled already.
