Small Cell Backhaul Architecture

A backhaul may include wired fiber optic and wireless components.

Small cell backhaul architecture.

In this paper we develop a novel wireless backhauling strategy for small cell networks based on dynamic base station bss cooperation which we call the fog radio access network f ran backhauling strategy. Additionally we are focused on the next generation of small cell architecture. This study analyses and compares various small cell backhaul deployment scenarios considering different starting situations backhaul technologies and small cell locations. The connection between the cell tower and the rest of the world begins with a backhaul link to the core of the internet service provider s network via a point of presence.

Developing efficient backhauling solutions for small cells is considered as one of the most significant challenges in the rollout of the upcoming 5g cellular systems where massive numbers of small cells will be deployed. Small cells are low powered cellular radio access nodes that operate in licensed and unlicensed spectrum that have a range of 10 meters to a few kilometers. This can take many forms. Cell phones communicating with a single cell tower constitute a local subnetwork.

For residential and many enterprise small cells this can be almost any broadband internet service including dsl and cable. This results in increased capacity requirements onto the backhaul links currently feeding the macro cell especially as more and more small cells are deployed. It has to be cheaper but it also has lower capacity requirements and many operators are willing to accept lower reliability and even to use license exempt spectrum. Small cell backhaul is the transmission link between the small cell and the mobile network operator s core network.

Small cell backhaul requirements different from macro cell backhaul. Small cells can be homed back to existing macro cells with combined small and macro cell traffic backhauled to the mtso. While 1gbps is the current maximum data rate of our backhaul products our engineers are developing 10gbps small cell backhaul solutions further lowering the total cost of ownership for mnos and making small cells even more cost effective.
