Using spectrum allocations to address indigenous policy obligations: the case of New Zealand

Bronwyn Howell & Xin Tang
Radio spectrum is fundamental to the operation of wireless communications services. In order to allocate radio spectrum for different services, spectrum is regulated via national laws, coordinated by an international body, the International Telecommunications Union (ITU). For the most part, national (state) governments undertake the legal definition and allocation of spectrum. The most common method of allocation is auction, where competing parties bid for the rights to use specific bundles of spectrum, ensuring that the...
