21 If the validity of a radio licence for operations in accordance with a network licence referred to in section 6 and a programming licence referred to in section 34 expires while the licence is still valid, the frequency reservation becomes valid again without an application. Section 46 Renewal of a radio licence without application Ficora may renew a radio licence without application by the licence holder for a maximum of ten years at a time, if the licence holder has given written consent to the renewal. Ficora may not renew a radio licence if the requirements of section 41 for granting a licence are not met or the requirements of section 49 for cancelling a radio licence are met. Section 47 Amending a radio licence During the validity period of a radio licence, Ficora may amend the licence terms without the consent of the licence holder if this is essential because of a change in the confirmed allocation plan for a radio frequency, regulations on frequencies or international treaty obligations, or if it is justified for the prevention or removal of interference in radio communications or on the basis of the radio frequency band’s primary purpose of use. For a network licence holder who has been granted a licence referred to in section 6(1), radio licence terms can also be amended if this is necessary due to a change in the economic or technical environment of the telecommunications operator or due to a new telecommunications operator entering the market or other change in market conditions that will necessitate a reorganisation of radio frequency use. The terms of a radio licence may also be amended by application of a radio licence holder. If a radio licence holder for an electronic communications service applies for an amendment to radio licence terms, Ficora shall, before issuing a decision, inform the licence holder of how re-examination would influence the radio licence, and allow the licence holder a reasonable time limit to withdraw the application. If the technology used in the provision of electronic communications services is not specified in the licence, the licence holder shall notify Ficora of the technology to be used prior to commencing operations. If the licence holder changes the technology used, it shall notify Ficora prior to implementing any changes. Section 48 Transfer and lease of a radio licence A radio licence for other than network or programming operations subject to a licence may be transferred. However, the transfer of a radio licence may be prohibited in the licence if the use of the radio transmitter requires a proficiency certificate referred to in section 265 or if the licence transfer would have a significant effect on the general development of the communications market. Such transfer shall be notified without delay to Ficora. Ficora may within a month of the reception of the notice reject the transfer of a radio licence if it is obvious that the requirements of section 41 for rejecting a radio licence are met. Relinquishing a licence to someone to whom a licence holder leases out or otherwise temporarily grants use of its radio transmitter is not considered transfer of a radio licence. In
