backhaul
Backhaul, in mobile networs, refers to the part of the network infrastructure that connects the edge of the network, such as cell towers or base stations, to the core network, which then connects to the internet or other networks. In mobile networks, backhaul connects mobile baseband units to the mobile switching center and then to the wider telecommunications network. It is essentially the link between the local networks and the broader internet.
The backhaul network is responsible for transporting all types of data, including voice, video, and other internet traffic, from the local networks to the core network. This is a critical function because it enables users to access the internet and other services.[1][3].
With the evolution of mobile networks to 4G LTE and 5G, the capacity and latency requirements for backhaul have increased significantly, leading to a greater reliance on fiber-based and point-to-point wireless backhaul solutions[1][3][4].
