Wireless technology has become a very powerful tool world-wide paving the way for a ground breaking new, highly convenient, way of making phone calls using wifi VoIP phones. As financial issues arrive, forcing many into economic hardship, we find that free is good and yet so hard to find. That is why making free phone calls using VoIP is certainly something to get excited about.

Though the use of VoIP to make phone calls has been in use for some time, there were pitfalls to the service, the most important being that callers were limited to their computer. Manufacturers quickly went to work, implementing their know how to create what are known as WiFi phones so that callers could feel free to roam while they talk on the phone to friends and family.

There are many other companies who ended up picking up the usefulness of VoIP phone calls such as Skype. When you sign up for Skype, you can call someone who is also a Skype member and the whole call is free of charge and free phone calls mean longer conversations but no one wants to have to sit in one place while having a lengthy conversation. WiFi VoIP phones make it possible for you to walk and talk at the same time, free of restrictions.

WiFi phones come with an antenna which sends and receives information to your computer through a wireless router. The router picks up the signals emitted by your phone and passes those signals along to the internet so that it is possible to place calls to another phone or computer.

WiFi telephones are convenient and much like their counterpart, the cell phone. The wifi phone looks much like a cell phone and transmits frequencies like a cell phone. What makes WiFi phones different is the fact that they use 802.11b/g technology which the cell phone and LAN line phone do neither.

When you use a WiFi phone, you are still using your computer to make the initial phone call but it is the phone that sends the signal to your router and then to your computer so that the computer is able to connect the call. The computer sends the information about the call back to the phone so that when you turn it on, you are able to hear a dial tone, dial in your number and make your phone calls.

VoIP phone calls are broken down into bits of data. Whenever you are speaking on the phone, your voice is sent out as data to the computer and onto whomever you are speaking with. If you have ever experienced a VoIP phone call, it works just the same only with the convenience of an actual phone in your hand.

Since there are program which are specifically designed enabling you to use VoIP technology, many manufacturers have designed WiFi phones to use those certain programs such as the previously mentioned Skype calling. Vonage is another popular VoIP phone service.

When you purchase a WiFi phone from companies such as Netgear, Linksys, ZyXEL and a few others, they may explain to you that they work with certain companies like Skype and Vonage or at least similar to the two. If that is the case, you will have to open an account with the provider and have your phone configured so that it is capable of calling within that network. Not all wireless phones require you to have an account or a certain program in order to use them by enabling you to use an open protocol from just about any location.

Wireless technology has made the world a very convenient place to live in for everyone by using radio waves to send and receive thousands of packets of information in a very short amount of time. There are WiFi hotspots available all over the world, enabling people to use various tools such as laptops, cell phones, PDA's and even VoIP WiFI telephones. This means you can travel as you please and still make free or low cost phone calls to friends and family.

A wireless router connects multiple devices to the internet at once. This means that you can run your computer or laptop at the same time that you are using your WiFi phone. The router decodes the bits of information so that it can then be sent to the Internet. The Internet responds to this information so that you can happily go about your business. The speed in which this information moves is so fast that most people fail to notice.

The frequency used for carrying data from the WiFi phone to the router runs at 2.4 GHz or 5 GHz. This is because the higher a frequency, the more information a signal can carry back and forth. As far as 802.11 technology, 802.11b runs the least amount of data at only 2.4 GHz. 802.11g is one of the most popularly used technologies because it is slightly faster than g and still nearly as cheap.

802.11a is considered a very fast frequency and becoming just as popular as 802.11b as well as 802.11g due to the fact that it is quite a bit faster than b/g frequencies but it is also slightly more expensive. 802.11n is the fastest, and newest, wireless technology available moving large amounts of data per second with few interruptions.

Not everyone is hooked on wireless phone calls as a form of communication and without a decent sized network of contacts within the VoIP community, it would be more practical to stick to typical land line or cell phone calls, though spreading the good news of WiFi phone technology would benefit, not only you, friends and family as well.

The fact that WiFi phones are capable of picking up hotspots does not exactly bode well just yet either unless the phone has a browser since some WiFi locations require this in order for you to gain access to them. Since you are constantly moving, your wireless network would constantly be changing as well and your phone would have to adjust to the change of network causing too many pauses and interruptions.

If all the few kinks of VoIP WiFi phone technology can be ironed out, it will end up being a new fad that will take the globe by storm. People will realize the benefits, sign up to the net work and start calling those they know for the wonderful price of free. Until then, it is still a very useful tool, even with the kinks. Especially if you do know a lot of people on the VoIP network which then makes this the perfect way of communication for someone like you.
