Licensing
The application forms [Office® Format - Word Document - Office®.] Modelo 047 ANACOM(DOC 334 Kb) (*http://www.anacom.pt/render.jsp?contentId=55129), [Office® Format - Word Document - Office®.] Modelo 047M ANACOM(DOC 278 Kb) (Madeira) (*http://www.anacom.pt/render.jsp?contentId=55129), [Office® Format - Word Document - Office®.] Modelo 047A ANACOM(DOC 223 Kb) (Azores) (*http://www.anacom.pt/render.jsp?contentId=55129) are used to request licences for networks solely made up of mobile stations (installed in vehicles or portable) emitting in simplex channels.
To install networks ?without fixed structure? it is not necessary to previously apply for ?band indication?. Thus, so long as the form Modelo 047 ANACOM is correctly filled out, a network licence may be issued, dispensing with other formalities.
In module 2 ? Number of stations to install ? the category corresponding to the number of stations to install should be indicated.
Module 3 must only be filled out when more than one channel is requested, a situation which imposes clear justification.
In module 4 ? Preferred frequency band for channel assignment ? the interested party may indicate preferences for the band in which the frequencies will be assigned; ANACOM will try to follow those preferences, but reserves the right not to respect the order indicated, for radio spectrum management reasons.
If no preference is indicated, ANACOM will assign frequencies according to the ?Criteria for Assigning Frequencies to PMR Networks from Land Mobile Servicehttp://www.anacom.pt/template15.jsp?categoryId=82291?.
Module 5 ? Network objective - should designate the specific purpose of the communications, which may not coincide with the applicant?s activity. For example, a passenger transport company may need a network for vigilance and security of its facilities; a banking entity may need a network to transport assets. This field is meant to provide information on the network user?s ?profile?, in order to harmonise sharing situations in the channels in which it is to be included.
In module 6 ? Network service area ? cells should be filled out to approximately indicate the region/area for which mobile station communications are planned.
The network licence can be issued as long as Model 047 ANACOM is correctly filled out; it will indicate the network?s composition, structure, technical characteristics and working conditions. The network may be used after its title-holder has received the licence.
Signature: it is indispensable that the signature be legally recognised
