If one or two cellular carriers gain control of enough spectrum, they may be able to prevent current and potential rivals from getting the spectrum needed to compete effectively. Thus, regulators typically attempt to protect competition through some form of limit on how much spectrum any one...

Emerging technology, coupled with effective policy reform, could lead to tremendous gains in spectral efficiency. This would alleviate the spectrum scarcity that many nations have experienced. To be effective, reform in spectrum policy must fit the realistic capabilities of emerging technology,...

Regulators in most countries limit the amount of spectrum that a carrier is allowed to obtain as a way of reducing the risk that rival cellular carriers will be unable to obtain the spectrum they need to compete effectively. For similar reasons, regulators may consider how a proposed merger...

The current spectrum management policy typically gives exclusive and unlimited access to license-holders within their domain, and offers meager transmission opportunities for non-license-holders. This paper addresses spectrum management techniques in which no licensing is required and individual...

What has been driving consolidation of the cellular industry in recent years? Now that traffic volumes are increasing rapidly, the cost of expanding capacity has become a large portion of expenditures for cellular carriers. This paper develops an engineering-economic model of the principal...
