 Some disadvantages of the lottery method was that some firm would engage in rent-seeking behavior, and try to get multiple licenses that they did not intend to use, but only intend to sell to another firm.In this situation not only were firms using rent-seeking behavior on a public resource, but the negotiations between firms could go on for years, meaning that frequencies were not being used and the public interest was not being served.A third method used to allocate bands is the administrative process, also called comparative hearings.
