Introduction to Mobile VoIP

Do you have a smartphone? Do you think you know everything about it? I bet you think you do. You can use an Internet browser, you have plenty of applications, e-books, pictures, audio, video and so on. Did you know, though, that a smartphone can provide more flexibility and better quality in your communication methods? Do you know how? This article will tell its basic facts to you, so if you would like to know the answers, then I suggest you to read it along and watch the video after.

VOIP

If you have used Skype, Google Voice, or any such applications on your computer, then you already know what VoIP means. It is a protocol that sets the rules of multimedia transmission over the Internet. That is where its name Voice over Internet Protocol comes from.

This protocol specifies the way of this transmission as digitalising analog audio signals, and then compress these data into data packets of 10-30 milliseconds of voice, before their transmission over the Internet. At their destination they are transformed back into voice signals coming from the speakers.

From here on, the article will enlist Internet connection types of cellphones and Mobile voip applications, which are supported by Ozeki Phone System, as demonstrated by Figure 1.

Mobile VoIP

It works similar on a cell phone as well. When you make a VoIP call, your phone connects to one of the following:

  • WAP: worst quality, hopefully your phone has access to any other type of Internet connection.
  • 3G: broadband Internet for cell phones with almost the speed of a DSL (Digital Subscriber Line, which uses phone lines for high-speed Internet connection).
  • Wi-Fi: Wireless Local Area Network, to which most smartphones are able to connect. Its advantage over 3G is that it is for free.

Applications

Cell phones need certain applications to be able to make and receive VoIP calls. The intent of this article is not to list them all, so here is a short list describing the most well-known and most popular ones.

  • Skype: You can call someone for free if he or she also uses Skype. You can also call a PSTN number, although its quality will not be the same.
  • Viber: It has a really great quality, unable to call PSTN (Public Switched Telephone Network, or the old, outwork network we use for communication for a century) numbers or a person using a different application, but it is for free.
  • Talkatone: It is based on a Google Voice account, and like Skype, it is great when you call some one using the same application, but when you call another application or a PSTN number the quality will also get worse.
  • Fring: It unites all the above mentioned applications, it has a good quality, and it is for free, unless you call a PSTN number.
