Detailed explanation-1: -The two main disadvantages of mesh topology are cost and complexity. Partial mesh setups help balance these issues, but a full-mesh, wired network is like a spider’s web of connections. Mesh networks have higher power consumption than other network types.
Detailed explanation-2: -In a mesh topology, all devices are connected directly to every other device on the network. If one link fails, there is always another available. It is the most fault-tolerant network topology.
Detailed explanation-3: -The theoretical number can get as high as 128 devices (eero) or 200 devices (Google WiFi). However, if these devices are doing high-bandwidth activities, like streaming or gaming, then the more accurate number is 28-30 devices at one time.
Detailed explanation-4: -Advantages of Mesh Topology Scalable: In a mesh topology, each node acts like Router. However, there are no exclusive Routers. It easy to add an additional node in this topology and connect it to the network. Additionally, to scale up the network, extra effort is not needed.
