Mesh Network Benefits

One of the positives is better coverage as you’re no longer relying on a router in one spot. Instead, a network of nodes working together.
No more problems of a single point of failure. If one node can no longer operate, the network can reroute to still communicate between the remaining nodes.
Taking the network down is impossible unless there is a worldwide catastrophe that wipes out all electronic devices.
The network works with minimal infrastructure and can therefore be deployed faster at a lower cost than traditional infrastructure.
There is no centralized authority in a mesh network. For that reason, some people compare it with what the Internet was back in the day: localised, anonymous, citizen-based, secure communication.
Additional devices in a mesh topology will not affect its network connection. Hence it will improve the traffic in the network.
