5. Spectrum management – brief introduction

6. 10.12.2007 / Mika Husso6 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: 1)Blocks of spectrum allocated to services by international agreements 2)National Regulatory Authorities (NRAs) assign licenses for use of specific frequencies to operators 3)When old systems ”die” frequencies can be reallocated Oper.1 Oper. 2 Oper. 3 Oper. 4

7. 10.12.2007 / Mika Husso7 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. 10.12.2007 / Mika Husso8 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. 10.12.2007 / Mika Husso9 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? …
