5. Spectrum management – brief introduction

6. Spectrum management – brief introduction • Spectrum management objectives: • Economic efficiency (spectrum to those who benefit the most from it) • Technical efficiency (high spectral efficiency and utilization) • Public policy (consistent with goverment goals for facilitating competition in telecoms market, retaining frequencies for emergency needs etc.) • Historically done by: • Blocks of spectrum allocated to services by international agreements • National Regulatory Authorities (NRAs) assign licenses for use of specific frequencies to operators • When old systems ”die” frequencies can be reallocated Oper.1 Oper. 2 Oper. 3 Oper. 4

7. Spectrum management – brief introduction • Known problems • Regulatory burden (increasing regulatory resources seldom solves problems related to regulation itself) • Inefficiency (inflexibility, users need to meet regulatory requirements even when not economically sensible) • Ineffictiveness (due to rapid change of needs but stable resources allocation, spectrum is not optimally distributed)

8. Spectrum management – brief introduction • How to attack the problems? • Utilization of market mechanism (spectrum auctions, trading of licenses) • The commons approach (licence exempt operation) • Creating financial incentives for efficient spectrum use • Generally, the principle would be to expose all spectrum users to the opportunity cost of the spectrum which they occupy * As spectrum is a scarce resource, its use involves an opportunity cost

9. Questions to be answered… • To what extent should spectrum be regulated and by whom? • When should and should we not let markets handle spectrum management? • How do we guarantee sufficient competition im the market to enable efficient distribution of spectrum? • How should we price the spectrum? • What steps should we take next to facilitate more efficient use of spectrum? • …
