mobile service and fixed narrowband service

The mobile communications networks (terrestrial, maritime and aeronautical) for the exclusive use of the radio spectrum, as well as the links between fixed points (point-to-point and multipoint links) with low-capacity pipelines (normally below 1 MHz) and other radio services such as Maritime and Aeronautical Radionavigation, are included in the section on mobile and fixed narrowband service.

A radio network belonging to the mobile and fixed narrowband service can have three types of architecture: fixed narrowband, mobile or a combination of both. A network of the first type will consist of a minimum of two fixed stations and a radio link communicating both stations. A network of the second type will be formed by at least one or more mobile and/or portable stations linked to each other or to base and repeater stations. The networks of the third type are usually complex networks consisting of a combination of the above.

The mobile stations themselves are those located on board vehicles while the portable stations are those that a person can take with them.

The processing of electronic communications networks also corresponds to the mobile and fixed narrowband service. The particular and specific processing of these networks can be carried out in Electronic communications service in harmonized bands.

The frequency bands commonly used for narrowband mobile and fixed-band networks are those of 68-87.5 MHz, 108-137 MHz, 146-174 MHz, 400-470MHz and others (Collected primarily in Notes UN-132, UN-18, UN-19, UN-102, UN-98, UN-31 and UN-40 of the National Frequency Allocation Table) and the typical bandwidths of radio channels are 12.5 or 25 KHz.

The applicant (the owner of the network or his authorized representative) who wishes to obtain an enabling title for use of the radio spectrum by radio networks of this service must request it through the electronic headquarters of the Ministry.

To do this, you must have a qualified electronic certificate. More information on qualified electronic certificates can be found on the following page: Trusted Electronic Service Providers.

Once at the headquarters, perform the application process. It can be a request for a new network or to modify an existing network. This request must be accompanied by a technical project electronically signed by a qualified telecommunications technician.

The technical projects will be composed of an XML file according to the XSD schemes established and available in the electronic headquarters, as well as of the additional PDF files that include the supplementary information not collected in the previous XML file.

More detailed information on how these applications are handled is available at the Ministry’s e-office at Processing of Radio Networks of the Mobile and Fixed Narrowband Service.

Once the application has been submitted, the applicant will receive, where appropriate, the documents relating to the authorization of the enabling title: the Resolution of authorization of installation of the stations, a technical annex with the authorized characteristics and the receipt of the reservation fee of the initial public radio domain Model 990.

Through the same link to the electronic office indicated above, the applicant can carry out all possible procedures related to the authorized enabling title: corrections, cancellations, etc.

Once the Resolution has been received with the approval of the technical project and the subsequent authorization for the installation of the radio stations, the request for the commissioning of the fixed stations must be submitted, within the deadlines established in said Resolution. See more information in Authorisations for the commissioning of radio stations.
