Monthly Mobile Broadband Flat Rate
Cost based on the price of the downloaded MB and the volume ofdownloaded data (use of the service). VAT, 30% of additional costs(aggregation, backhaul and core network) and a 30% profit included

Where and what is it used for?
Mobile Communications Regulatory Projects in collaboration with thegerman company WIK-Consult GmbH
Development of a 2G/3G Mobile Network cost model for the SwissRegulator BAKOMDevelopment of a 3G Mobile Network cost model for the AustrianRegulator RTR GMBHDevelopment of a Mobile Network cost model covering 2G, 3G andLTE for the German Regulator Bundesnetzagentur

Conclusions
This SW tool offers a solution to consulting companies for mobilecommunication regulatory projects:
- RAN strategic planning- Deployment Costs Optimization
It gives the chance of analyzing every radio access technologies thatare currently or going to be deployed in a near future, performingsimulations based on highly accurate, reliable and adaptablealgorithmsThis study is focused on the efficiency comparison, in terms of cost,between the two most relevant technologies when offering the mobilebroadband access service, HSPA and LTE
J.E. Sánchez-García (GHEODE) SNPT 28th November 2012 16 / 18
Conclusions
LTE is more efficient for transferring high binary rate data than HSPAInvestment cost savings from 70% to 80% when installing LTEequipment instead of HSPA equipmentFactors that should be taken into account when deciding whichtechnology is deployed:
- Type of subscriber and demand of the service- Urban, suburban or rural environment- Available spectrum for each technology (bandwidth and frequencyband)
