Developed from the same software base which created AttoEPC, AttoEdge is a 3GPP standards-compliant core network product that provides public network extension and pushes core functionality right out to the network edge. AttoEdge supports a local breakout capability, which enables SIPTO based data offload, compliant to TR 23.859: “Local IP access (LIPA) mobility and Selected IP Traffic Offload (SIPTO) at the local network”.
The principal components of AttoEdge are :

Enterprise Networks
The growing availability of unlicensed and light licensed LTE capable spectrum, such as that enabled by CBRS, supplementing the ubiquitous licensed 4G capable spectrum, has significantly increased the opportunity to bring mobile network innovation into the enterprise through the deployment of small cell RANs and innovative mobile core software solutions.
To address this opportunity, AttoEdge can be deployed in the enterprise as part of a public network extension. Basic capabilities provided by public network extensions include enhancing coverage and capacity within the enterprise, whilst providing enterprise network users with access to all of the usual public network services.
AttoEdge builds on these basic capabilities to provide value-added capabilities that can not be delivered by traditional methods of extending the public network, such as DAS (Distributed Antenna Systems).
The introduction of AttoS1GW isolates the enterprise network from the public network. In addition to reducing the burden of new S1 connections connecting in the public network’s existing macro core, this isolation also allows AttoS1GW to manage handovers between enterprise deployed eNodeBs, without the need for complex, time-consuming and resource-hungry interaction with the macro core.

Enterprises benefit from purpose-built corporate data networks and from high capacity broadband access to the public internet. A major benefit of an AttoEdge enabled enterprise mobile network is the ability to offload data from the mobile network onto the corporate data network or public internet.
These networks are specifically created to handle large quantities of data and the use of such networks is now rarely charged on the basis of usage. From both the performance perspective and the cost perspective, data offload makes sense.
By deploying AttoLGW as part of the AttoEdge installation in the enterprise network, enterprises gain the ability to enable SIPTO based per APN data offload, sending their mission critical data directly over the networks best able to hand them, instead of overworked public network mobile cores.

Residential Deployment
AttoEdge is an excellent choice for deployment in residential applications, as part of a residential data offload solution. When deployed inside residential Femtocells, the ability of AttoEdge to automatically load balance across the available CPU cores significantly reduces latency, as individual packets are distributed across different CPUs.
AttoEPC is implemented as distinct Linux applications, maximising deployment flexibility. These applications can be deployed directly on the bare metal of a standalone COTS server. This COTS server could be located remotely, in an enterprise, or could be deployed in a data centre, or in the Cloud.
In this residential deployment, AttoEdge utilises the same AttoS1GW and AttoLGW components as are deployed in the enterprise application:

In each case, the data offload functionality provided by AttoEdge has the same data offload impact on the residential network, offloading broadband data from the mobile network onto the residential broadband network, a fast and efficient connection, which has been specifically created to cost-effectively carry large quantities of data at high speed.
The benefit to the mobile network operator is that expensive resources within the macro network core are no longer required to carry this data, giving the core more opportunity to focus on its essential signalling functions and other operational support responsibilities.
