  • Decentralized Backhaul:
    Decentralized systems distribute the processing across multiple nodes, which can balance the load and improve redundancy. They offer enhanced performance but require more robust management protocols.

Mesh Network Backhaul

Mesh networks have gained popularity as a solution for enhancing WiFi coverage in larger areas. In this context, mesh backhaul refers to how the routers and nodes communicate with one another.

Within a mesh network, each node typically connects to multiple others, creating a web of interconnections. This architecture allows devices to connect to the node that provides the best performance at any given time, reducing congestion and potential slowdowns.

Factors Affecting WiFi Backhaul Performance

Many elements can influence the effectiveness of a WiFi backhaul system, significantly impacting the overall performance of a network.
