What is Backhaul?
In both the technical and commercial definitions, backhaul generally refers to the side of the network that communicates with the global Internet, paid for at wholesale commercial access rates or at an Internet exchange point or other core network access location. The most common network type in which backhaul is implemented is a mobile network. A backhaul of a mobile network, also referred to as mobile-backhaul connects a cell site towards the core network. The two main methods of mobile backhaul implementations are wired fiber-based backhaul and wireless point-to-point backhaul.
Wired/Optical fiber Backhaul
Wired backhaul technologies rely on a direct physical connection via Optical Fiber to the repeater node or to the edge nodes. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fibre by using different wavelengths (i.e., colours) of laser light. With the technological advancements in these optical technologies Yash infosystems and its team promises to provide the unlimited bandwidth.
Wireless Backhaul options are also available in the form of refers to technologies that use point-to-point or point-to-multipoint radio or microwave frequencies to transmit signals between hub sites and an end-user receiver. The most common wireless backhaul, operate in the unlicensed wireless (license-exempt) 900MHz (902-928), 2.4GHz, 5.3GHz, 5.4GHz, 5.8GHz, 24GHz, and 60GHz frequencies of the RF spectrum.

Backhaul is connecting the edge to the core without the cost of wires. In a hierarchical network the backhaul segment of the network is the link between the core network, or backbone network, and the sub networks at the edge of the network.
