Calculating the costs of a next generation access network

Trenching is extremely costlySo reduce this as much as possible

Central Office Buried drop point Facade drop point Aerial drop point

And reduce the total deployment length

Central Office Fiber cable Buried drop point Facade drop point Aerial drop point

By constructing a Steiner Tree

NP-hard heuristic techniques

Interesting research topicsClustering & cherry pickingRing structures for resilience

Finally there are also different fiber architectures for the access network

Service Provisioning

Up & Running

Deployment

The other parts of the physical deployment have a much smaller impact

Up & Running

Deployment

Using an alternative to trenching (here aerial) can save considerable

trenching72%

Aerial 30% of customers10% of the installation length

Service provisioning takes care of connecting the customer

Service provisioning consists of 4 large parts

Up & Running

Deployment

Especially the equipment consumes a large part of the costs

administrative11%

outdoor15%

indoor10%

equipment64%

Up & Running

Deployment

There is a trade-off between pre-installation and later installation

preinstallation12%

later installation24%

equipment64%

Up & Running

Deployment

maintenance and repair customer equipment

maintenance and repair inside plant

maintenanceand repair outside plant

operational planning

marketing9%

pricing and billing9%

continuous1%

Finally there is also the OpEx for keeping the network up and running

So – We’ve shown an approach forcost breakdown and balanced (zooming) estimation

up and running9%

deployment 67%

Up & Running

Deployment

1. Deployment (70%)

mainly trenching (80%) optimized installation tree cherry picking alternative installation types

Up & Running

Deployment

2. Service Provisioning (25%)

mainly equipment ONU (65%)

advantage of pre-installation reduced trenching early customer binding

Up & Running

Deployment

3. Keep up & running (10%)

mainly maintenance (60%)

In the future we plan to …

Proceed on this approach

Investigate trade-off between CapEx & OpEx Model the cost-structure in more detail Expand this approach to other technologies

(e.g. wireless)
