VoIP vs Wifi Calling: A Comprehensive Comparison | Xinix

The significance of effective communication technologies in today’s interconnected world cannot be overstated. These technologies have a crucial role in empowering organizations through effective communication, fostering connections, driving progress and facilitating a global presence and connectivity. Technologies such as voice over internet protocol (VoIP), VoIP phone over Wifi and Wifi calling have transformed the whole concept of communication no matter its personal or commercial level communication.

However, there are certain limitations as well. Not every mode of communication is good and suitable for everyone. It largely depends on usage and the purpose intonated. Of course the business phone system is different and requires optimal continuity and reliability. VoIP or Wifi calling both have their own specifications this guide will help you have a profound understanding of both technologies so you can choose the best suited option in future:

Voice over Internet Protocol (VoIP)

VoIP is a group of technologies with which users can make calls through internet connection. This technology converts data into small IP packets called codecs which are then transmitted over the internet. VoIP calls are not operator dependent. Furthermore, you do not need a sim card to make calls. However, you will need a stable wii connection or mobile data to have internet access and to make a call. 

Wifi calling

Wifi calling is somewhat the same as the conventional phone calls and offers the same features as well. The main difference is that Wifi calling establishes the connection through wireless internet connection. Typically, when we make a call, the connection is established through the mobile provider’s network. However, in case of Wifi calls, the calls are routed to Wifi instead of mobile network.

Simply put, the Wifi calling uses VoIP technology and thus it is often called VoWifi referring to voice over Wifi. This calling feature is enabled by your cellular mobile network provider.

Here is how Wifi calling works: 

The mobile network provider enables the feature for voip over Wifi call. When you make a call with this feature enabled, your phone will automatically identify the strongest network available near you. It can be Wifi or even a mobile data network, given that it provides stable internet connection. The call will be routed through a mobile or Wifi network.

Usually, the mobile network providers do not charge additional fee for voip over Wifi calling. instead, they will deduce the Wifi call minutes from your monthly calling plan.

  • VoIP is data transmission over an IP based network.
  • It requires a proper infrastructure such as server and routers provided by network provider

  • Unlike VoIP, Wifi call is specifically a feature of smartphones or mobile only.
  • Call quality is good given that internet connection is strong and reliable. However, it may be affected due to network area coverage.
  • Lastly, the cost is not an issue here. This calling feature is more like a value added feature offered by mobile network providers.

  • Some devices may not be compatible and do not have inbuilt feature  
  • This feature is only for mobile phones and lacks advanced features of VoIP  
  • Possible delay in data transfer due to weak connection
  • Inability to make calls during international travel. And if roaming is enabled, charges are high.
  • Additional charges of mobile data may incur in case of weak Wifi connection

VoIP vs Wifi calling – the better choice

Having a thorough understanding of both communication technologies is important for the users to make the right decision. Both VoIP and Wifi calling offer amazing features and call quality. However, there are certain limitations with both.

For instance, if you are based in a small area with poor network coverage, Wifi calling can be a good choice. However, you will still need a strong and stable connection with sufficient bandwidth to handle the traffic for Wifi VoIP. It will improve call quality and minimize latency.

VoIP, on the other hand, is an ideal choice for business communication as it offers various advanced features. It is flexible, accessible from various devices, works well for remote workers too and is cost-effective too for business needs.

In any case, quality of services is the prime importance. Whatever the communication technology you choose, make sure it aligns with your personalized needs. It must cater to your needs of unified communication while being reliable and affordable as well.
