Now Calls Can Be Made Over The Phone Without A Network, Through Vowifi.
Wi-Fi is the name of a wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for "wireless fidelity," however this is not the case. Wi-Fi is simply a trademarked phrase that means IEEE 802.11x.
Wi-Fi networks have no physical wired connection between sender and receiver by using radio frequency (RF) technology -- a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space.

Wi-Fi is supported by many applications and devices including video game consoles, home networks, PDAs, mobile phones, major operating systems, and other types of consumer electronics. Any products that are tested and approved as "Wi-Fi Certified" (a registered trademark) by the Wi-Fi Alliance are certified as interoperable with each other, even if they are from different manufacturers. For example, a user with a Wi-Fi Certified product can use any brand of the access point with any other brand of client hardware that also is also "Wi-Fi Certified".
Wireless networking - which is often just known as Wi-Fi - is a way of getting broadband internet without wires.
Wi-Fi allows you to connect several computers at once, anywhere in the house - or if you have a laptop, to even use your computer in the garden. You don’t need to install extra phone lines or cables.
Wi-Fi creates a network in your home or office – a little zone where computers can get broadband internet. It uses radio waves, just like TV or mobile phones. You may sometimes hear this zone referred to as a WLAN (Wireless Local Area Network).
A device called a wireless transmitter receives information from the internet via your broadband connection. The transmitter converts the information into a radio signal and sends it.
You could think of the transmitter as a mini radio station, broadcasting signals sent from the internet. The ‘audience’ for these transmissions is the computer (or computers, as more than one, can connect at the same time) which receives the radio signal via something called a wireless adapter.
The whole process, meanwhile, works in reverse, with the computer sending information to the wireless transmitter. It then converts them and sends them via your broadband connection.
