In a hierarchical telecommunications network, the INSTAGRAM [1] part of the network includes an intermediate link between the main network, or backbone network, and small nodes at the edge of the network.

This is the most common type of network where the return flight is performed using a wireless network. As a feedback network, also called a feedback operator with the target cell, towards the main network. The two main deployment methods for mobile return cargo are fiber-optic return flight and point-to-point wireless return flight.[2] Other methods, such as data transmission via cable, satellite, and point-to-multipoint wireless technologies, are gradually being phased out, as bandwidth requirements and latency may be higher than in 4G and 5G networks.

In both technical and commercial definitions, backhaul typically refers to that part of the network that cooperates with the global Internet, paid at wholesale commercial rates for access to a data exchange point on the Internet or elsewhere accessing the main network. Sometimes mid-level networks exist between the private NETWORK and its display. This can be a local WAN connection.

Mobile phones that communicate with a single cell tower are local subnets; communication between the cell tower and the rest of the world begins with feedback from the ISP’s core network (point of presence). The return flight can include wired, fiber-optic, and wireless components. Wi-sharing, the use of microwave bands and networks, and national network topologies that can use a high-capacity wireless channel to transmit packets to the oven or fiber channel.
