A wireless network is a flexible data communications system, which uses wireless media such as radio frequency technology to transmit and receive data over the air, minimizing the need for wired connections. Now you can take your laptop and get connection to the Internet wherever is offered wireless service. But you have to follow some security steps to keep your data safe.

How wireless works
Wireless (Wi-Fi) or 802.11 networks is a method of connecting a computer to other computers or to the Internet without linking them by cables.
Wi-Fi networks use radio technologies called IEEE 802.11a, 802.11b or 802.11g to provide secure, reliable, fast wireless connectivity.

Security threats
 The most common wireless encryption standard, Wired Equivalent Privacy or WEP, has been shown to be breakable even when correctly configured
 Some electronic equipment can interfere with radio waves and disrupt your Wi-Fi network
 MAC Address Spoofing, etc.

How to protect your wireless connection
 Change default settings
 Use encryption
 Use anti-virus software
 Turn off your wireless network when you know you won't use it and also turn off identifier broadcasting on your wireless router. So your computer won't send a signal to any device in the vicinity announcing its presence
