This report sets out the results of NERA’s modelling of the economic benefits of three alternative scenarios for the use of the GSM 1800/DECT guard bands.

These three scenarios, which were set out in Ofcom’s Consultation Document of April 2003, are:

  • To make the spectrum available, on a national or regional basis, either to the existing GSM operators or to new entrants wishing to provide public mobile telecommunications services.
  • To make the spectrum available for short-range, low power use on a licence-exempt basis.
  • To retain the guard band and leave the paired band unassigned, in order to assist migration of GSM 1800 to future IMT-2000 use and to facilitate testing and development licensing.

In the report we set out:

  • NERA’s specification of the three scenarios for the purposes of economic impact modelling.
  • A discussion of the treatment of key modelling issues, such as:
    • the time period to be modelled;
    • how the benefits (both producer and consumer) are to be measured under the different scenarios; and
    • the stylised examples to be modelled under scenario 2.
  • A summary of the overall modelling approach that has been used, and how this differs between the different scenarios. This includes a schematic of the model, a high-level discussion of the modules within the model, and a description of how information will flow between these modules.
  • A description of the modelling work carried out in each module. This includes a discussion of data sources and any assumptions made.
  • The results of the economic impact modelling and a discussion of their implications.
