Important: While other people’s phones are used to send a message, only the sender and the receiver are able to see the content of the message. The more phones you have, the further a message is able to travel. Basically, multiple phones create a path of communication.
When turned on, the signal is able to piggyback from one cell phone to the next, until it reaches its intended destination. Some mesh messaging apps have a P2P mode. There is, however, a way to increase the distance a message is able to travel: through a peer-to-peer mode (P2P). You basically have to be at proximity to be able to communicate. Neither Bluetooth nor direct Wi-Fi allow for a wide range when trying to send messages between two phones. The range of a direct Wi-Fi connection is roughly about 200 feet, or 60 meters. Regular wireless networks typically use multihop communication. The wireless connection only exists between the two devices, which is why it’s also called a single-hop communication. Unlike a Wi-Fi signal you connect to from a router, direct Wi-Fi (sometimes also called ad-hoc Wi-Fi) is a limited connection that is created between two phones. The maximum range between devices is about 300 feet, or 100 meters. It’s the same technology when you use Bluetooth to transfer music or images from one device to another. Two devices are able to use Bluetooth to set up a secure peer-to-peer connection. Instead, they rely on Bluetooth or direct Wi-Fi connection. The off-grid messenger apps, also known as mesh messengers, don’t need access to public infrastructure like cell phone towers or internet to send messages from one phone to another. Offline messaging is a new trend in secure communication. What is offline messaging, and how does it work? Can offline messengers replace messaging apps?
