We have a framework that guides the transfer of spectrum licences. According to article 40 of that framework, such an analysis typically takes into account the following factors, among others: spectrum licence holdings; the general distribution of allocated spectrum; current and potential services; the availability of other spectrum bands; the relative usefulness of that spectrum; the degree of network deployment; the characteristics of the region; and any other relevant factors, taking into account the policy objectives.
