1. A method of allocating a shared radio frequency spectrum among a plurality of radio access networks (RANs), the method comprising:
receiving a request for access to the shared radio frequency spectrum from the plurality of RANS;
requesting an interference status from at least one of the plurality of RANs in response to the request for access to the shared radio frequency spectrum;
receiving one or more intolerability declarations, each intolerability declaration indicating an intolerable interference within the shared radio frequency spectrum between one or more user devices connected to a respective first RAN and a respective second RAN of the plurality of RANs;
granting the plurality of RANs initial access to a first radio frequency range of the shared radio frequency spectrum; and
dividing access to the shared radio frequency spectrum among the plurality of RANs such that for each intolerability declaration the intolerable interference is avoided;
wherein the dividing access to the shared radio frequency spectrum comprises granting the respective first RAN access to a second radio frequency range of the shared radio frequency spectrum which is different from the first radio frequency range.
