So, if there are fewer devices in an area, you won’t be able to send your messages far. First is its dependence on running nodes. However, if there are enough devices in an area, the app can use these devices as nodes to transfer messages to longer distances.Īs you might have guessed, using Bluetooth or WiFi mesh network technology also has its fair share of disadvantages. In direct peer-to-peer messaging, an offline messaging app generally has a range of about 100 meters. This last feature helps offline messaging apps overcome one of the biggest drawbacks, which is “range”. The beauty of mesh networking is that not only it allows direct peer-to-peer communication but it can also broadcast information to all nearby devices.įinally, it can also use nodes to send messages to devices that are out of range using other nodes as data transfer nodes. So, if you and your friends have the same offline messaging apps installed on your device, you can communicate with each other without internet. The network uses these nodes to transfer data across devices.
Instead of using mobile or WiFi data like popular messaging apps such as WhatsApp, the offline messaging apps create a peer-to-peer Bluetooth mesh network or Wifi Direct-based network on your phone eliminating the need for mobile data services.Ī mesh network is a type of network technology where each and every single node is connected with one another.
This will help us understand not only how these app works but also there limitations. Before we get to our list, let’s first talk a little bit about the technology behind these apps.
