Client successes

STEM is used by operators, vendors and enterprise users to model service-level requirements for networks and to calculate the financial implications of different technology or roll-out scenarios going forward.

STEM features an integrated cost-allocation function which supports detailed profitability analysis at the service level.  For an equipment vendor, STEM adds great value for marketing and business development units as a persuasive medium for communicating equipment sales propositions.

A business model for WiMAX mobile

Another Masters student at CEFRIEL has considered the economic aspects of WiMAX. A previous STEM model for a nationwide mobile access network has been updated and improved with a more accurate path-loss model, more detailed tariffs, and additional network elements.

Evaluating DVB-H value chains in Italy

Researchers at CEFRIEL have developed a STEM model for the introduction of DVB-H which considers the selection of geographical areas and customer segments to be served, the services to be provided, and the technology used to provide the services, for several value-chain scenarios.

Modelling the costs of ICT infrastructures for tendering purposes

Clients demand a single price-per-port for convergent solutions which integrate network platforms, LANs, telecommunications systems and voice traffic volumes. This article, first published in the German-language telecoms journal NET, describes how the costing of telecommunications projects can be made with STEM.

The important economic decision-making criterion for IPTV networks

Carriers who are seeking to build new IPTV networks face a number of architectural questions and issues. Juniper Networks has developed modular bottom-up models with STEM to help carriers evaluate different technical solutions for their networks.

Analysing the impact of the incumbent's wholesale prices

Lator, a Croatian telecoms consultancy, has used STEM to build a bottom-up business model of an alternative operator using carrier pre-selection (CPS), identifying the key drivers through sensitivity analysis.

Modelling public safety radio networks
