A mesh network means that each device is connected to other devices in range, rather than just to a central hub. Compared to a traditional network, such as home Wi-Fi, which can be thought of like spokes on a wheel all coming from the centre, a mesh network would be more of a web of interconnected nodes. This distributes the wireless signal more uniformly over a larger area, helping to provide a better coverage throughout a physical space, and allows for more reliable connections as there shouldn't be a single point of failure.

Building materials, wiring, and pipes within walls and floors can affect wireless signal strength, so it is not uncommon for there to be 'dead spots' where devices cannot connect to a central hub due to obstacles in-between them. Dead spots and signal interference are important considerations both in a finished building, including domestic dwellings, but also apply to construction sites and other temporary venues like music festivals. If set up correctly, mesh networks allow devices to be placed in those locations where they would be incapable of communicating with a central hub and bypass the obstruction by communicating with another device in a different direction.
