Wi-Fi stands for Wireless Fidelity. It is often used to refer to wireless networks -WLANS and was associated with equipment such as laptop computers and PDAS, allowing them to connect to wireless Internet connections.

Computers may be built with Wi-FI pre installed, or you can purchase a Wi-Fi networking card, allowing your desktop computer to become wireless. Now, Wi-Fi has been associated with VoIP phones.

Now that VoIP and Wi-Fi have joined forces their new acronym is VoWiFi. This stands for Voice Over Wireless Fidelity. Basically, VoIP is the ability to transmit phone calls over an IP address or High speed Internet connection and Wi Fi is the culmination of wireless internet. So Vo WiFi is transmitting a phone call through wireless Internet. Connections to a Wi Fi server are made when a Wi Fi device can connect to a Wi Fi access point. The access points are spread out, and are called, “hotspots”. It is possible to use someone else’s access point with your wireless device, and this has raised the question of security. This poses to be VoWiFi’s greatest current challenge. Currently, wireless customers can access other’s access points just by entering their hotspots. This has led to laptop’s suddenly switching networks, or joining in another’s access points without permission. There have already been instances of people tapping into files and documents due to the fact that wireless hot spots transferred networks. There are other technical kinks to work out as well.
