Spectrum management – brief introduction

10.12.2007 / Mika Husso 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:1) Blocks of spectrum allocated to services by international

agreements2) National Regulatory Authorities (NRAs) assign licenses

for use of specific frequencies to operators3) When old systems ”die” frequencies can be reallocated

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)

10.12.2007 / Mika Husso 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

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?• …
