Wi-Fi is a type or brand of wireless technology that is co-owned by a group called the Wi-Fi Alliance. The W-Fi Alliance’s goal is to improve the inter-operability of wireless local area networks or (WLAN) products by following the IEEE 802.11 protocols and standards.
This technology is usually reserved for mobile computers and lately, mobile phones as well as PDAs are designed to be Wi-Fi-friendly as well. As it is a wireless network, Wi-Fi does not have the familiar Ethernet cables that are used to connect one computer to another or as way to connect a computer to fast internet.
Another term being kicked around in the wireless WLAN community is, Wi-Fi hotspots, or just simply hotspot. A Wi-Fi hotspot is a public area that offers paid or even free wireless internet connection to your device… (laptop, phone, PDA etc.). Most of these services cover only a small area (for example. hotel lobby’s or libraries), while others may cover an entire city or downtown area. (known as municipal hotspots).
While having these Wi-Fi hotspots has made for cheap affordable and convenient internet connection possible, there are some security issues that accompany this technology.
Some Wi-Fi hotspots are left unsecured, so any data you may sent over the Wi-Fi network is not properly encrypted. Because of this, malicious hackers can monitor the data you send who are using the same Wi-Fi network. This can open yourself up to identity theft or worse.
There are however several solutions such as Virtual Private Networks or (VPN’s), that has recently been made available. VPN’s are secure, but are not yet widely used because of the costs of implementing the network.
