Small Cell Backhaul Architecture

Additionally we are focused on the next generation of small cell architecture.

Small cell backhaul architecture.

This can take many forms. Small cell backhaul requirements different from macro cell backhaul. Cell phones communicating with a single cell tower constitute a local subnetwork. 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.

Fog radio access network. At first sight small cell backhaul can be perceived as a dressed down version of its macro cell counterpart. Piggybacked on macro cells. For residential and many enterprise small cells this can be almost any broadband internet service including dsl and cable.

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. 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. 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. 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.

Small cell backhaul is the transmission link between the small cell and the mobile network operator s core network. A backhaul may include wired fiber optic and wireless components. Recent fcc orders have provided size and elevation guidelines to help more clearly define small cell equipment they are small compared to a mobile macrocell partly because they have a shorter range and partly because they typically. 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.

This results in increased capacity requirements onto the backhaul links currently feeding the macro cell especially as more and more small cells are deployed.
