Fundamentals and Principles in Spectrum Management



Fundamentals and Principles



The Authority, in spectrum management, considers;

  • a) Providing efficient competition and ensuring non -discrimination among operators in electronic  communications  sector,  providing  transparency,  effective  and  efficient  usage  of spectrum, preventing radio broadcasts from constituting electromagnetic interference on each other,
  • b) The strategies and policies set by the Ministry of Transport as well as the current and future needs of our country,
  • c) The decisions of the international and regional organizations such as ITU, IMO,  ICAO and CEPT, in electronic communications sector, bilateral and multilateral agreements and EU legislation,
  • d) Implementation of technological innovations and promoting research and development activities and investments,
  • e) Giving priority to national security and public order requirements and emergency situations such as natural disasters and extraordinary situations. 
  • f)  Preventing or minimizing the effects of harmful electromagnetic interference that may occur in the borders on the neighbouring countries when making frequency allocation and assignment and providing efficient and effective use of spectrum mutually.


Preparation and Updating of National Frequency Plan


1-)  Frequency band allocated for electronic communication is from 9 kHz to 3000 GHz. In case of international regulation, frequency bands over 3000GHz could also be used for electronic communication,

2-) In the National Frequency Plan, frequency band is divided into nineSub -bands as indicated in Table 1. Units of the frequencies in the interval of;

  • a) 3 - 3000 kHz is indicated as kHz,
  • b) 3 - 3000 MHz is indicated as MHz,
  • c) 3 - 3000 GHz is indicated as GHz .

3-) The  National  Frequency  Plan  is  prepared  under  the  fundamental  basis  and principles  expressed  in  Article  5.  National  Frequency  Plan  consists  of  general  and  detailed frequency   plan,   frequency   interval   for   projected   systems,   output   power,  authorization procedure,  reference  information  and  remarks.  Technical  terms  and  abbreviations  used  in spectrum   management   and   in   the   National   Frequency   Plan   concerning   the   wireless applications,  wireless  stations  and  systems,  application  terms,  common  usage  of  frequency and space applications are published with the National Frequency Plan.

4-) In the National Frequency Plan, frequency bands which will be assigned to Turkish Armed Forces and bands which will be assigned to Radio and Television Supreme Council for broadcasters are indicated separately,

5-) Terms   and   conditions   regarding   the   National   Frequency   Plan   and   its implementations are announced via official web site of the Authority. In case of necessity, the announcement may be done via web sites of international and regional organizations of which Turkey is a member, such as ITU and CEPT

Frequency Assignment



1-) Those that are willing to install and operate radio equipments or systems must have their frequency assignment and registration procedures approved by the Authority. However, for the frequencies which are indicated in the regulations of the Authority and that can be used without any permission of radio system installation and usage and without any radio licence, frequency assignment is not done. The radioequipments and systems to be used without a need for permission for installation and use and radio license, are used so as not to cause any electromagnetic interference on the radio equipments and systems of operators or users that are given authorisation by the Authority and the users of such equipments and systems must accept the electromagnetic interference ca

used by the radio systems using the assigned and registered frequencies.


2-) Turkish  Armed  Forces  including  the  needs  of  General  Command  of  Gendarmerie and  Coast  Guard  Command,  Undersecretariat  of  the  National  Intelligence  Organization, Ministry  of  Foreign Affairs,  and  Security  General  Directorate  shall  be  given  priority  in frequency assignment as well as the emergency situations thereof.

3-) Turkish  Armed  Forces  and  Radio  and  Television  Supreme  Board  make  and  implement frequency planning in frequency bands allocated thereto, within the framework of the National Frequency Plan.


4-) The  channel  plan  in  frequency  assignments  is  made  considering  the  decisions  of international organizations such as ITU, IMO, ICAO, EU and CEPT.

5-) The  frequencies  are  assigned  to the  operators  that  are  subject  to  authorization  for not much than the duration stated in certificate of competency of the right of use.

6-) For the users of radio systems that are not subject to authorization, assignment of frequencies is done for maximum of five years, and if necessary, this is done with the grant of the  radio  system  installation  and  usage  permission  on  the  basis  of  common  usage  basis.  The duration  of  use  of  the  frequencies  assigned  is  equal  to  the  duration  of  the  permission  of system  installation  and  use.  At  the  end  of  the  duration  of  permission,  the  demands(s)  of  the users  of  the  radio  systems  are  evaluated  and  their  duration  for  use  could  be  extended according to the result of evaluations.

7-) The frequencies that will be assigned for  all kinds of maritime and aerial band radio communications systems and navigation safety communications systems, whose installation, having third parties to construct and issuing permission for usage and registration procedures are carried out by Directorate General of Coastal Safety, are determined by the Authority.  

8-) In frequency assignments, in order to meet the need of radio communication sufficiently, restrictive measures can be taken on the number of frequencies to be assigned.  Additionally, for the frequencies assigned, necessary limitations can be put on the technical parameters such as the location of the usage of the system, transmission power, antenna type, antenna direction and antenna height by the Authority. 

9-)  The Authority shall take the necessary measures in order to ensure that the frequencies assigned to the operators within the framework of authorisation regime are not  affected by any harmful electromagnetic interference.

Frequency Registration

1-)  Those that are willing to install and operate radio equipments or  systems must have their frequency registration procedures done by the Authority. However,  for the frequencies to be used in the radio equipments and systems which do not need any  permission of radio system insta llation and use and radio license as stated in the Regulations  published by the Authority, frequency registration is not done.


2-)  National  registration  of  the  frequencies  assigned  is  done  considering  the  duration of assignment;

  • a-) After the notification that the operators install the electronic communications infrastructure or network and begin to operate,
  • b) After giving permission of radio system installation and use to radio system users who are not subject to authorization,
  • c) After Turkish Armed Forces, General Command of Gendarmerie and Coast Guard Command as well as Ministry of Foreign Affairs, Telecommunication Communication  Presidency, Undersecretariat of National Intelligence Agency and the Security General  Directorate, limited to issues relating to their purview set out in their establishment laws, give  notice to the Authority following the installation of the systems.


3-) The international frequency registration procedures that should be done through ITU are done by the Authority. The internati onal frequency registration procedures that should be done through ICAO are carried out with the coordination of Directorate General of Civil Aviation by the Authority.

Change of Frequencies


1-) If the communication cannot be achieved or in spite of the technical regulations if the harmful electromagnetic interference cannot be removed frequencies assigned and frequency bands can be changed by the Authority. Besides, due to technological  progress, regulations made by Authority in order to ensure the effective and efficient usage of spectrum or due to changes in the National Frequency Plan made in accordance with the regulations done by international organizations, any change including cancelation of the frequencies assigned and registered to the operators and users can be done by the Authority. Regarding the changes to this registration(s) and assignment(s) made by the Authority, frequencies of the operators and users will be kept as it is as much as possible and in case of necessity, comments of operators and users will be taken. In addition, in the frequency changing process of operators with limited quantity of right of use, provisions of the tender specifications and certificate of competency of right of use are also taken into account.

2-)  In terms of the concession agreements, transactions such as the withdrawal of frequencies assigned, changes and additional frequency assignments are conducted due to the terms and conditions set forth in the relevant tender specifications document and/or contract.

3-) In case of any harmful electromagnetic interference, principle is that the priority is given to protect the frequencies assigned to the operators as it is. If a harmful electromagnetic interference occurs between any frequencies assigned, the previously assigned frequency of the operator and/or user is protected.

4-)  Authority gives a reasonable time to the operators and users in case of any change in frequencies assigned. Operators or users shall not have the right to demand indemnity or any expenditure item which arises as a consequence of the adaptation process for the changes to be done in the National Frequency Plan from the Authority or users.

Frequency Coordination


1-)  Frequency coordination transactions for terrestrial, aerial, maritime, satellite and radio and television broadcasting services, are conducted with the neighbouring and related countries via bilateral or multilateral agreements by the Authority. In case of lacking of such agreements frequency coordination is done by the Authority within the framework of procedures of ITU and CEPT. The international frequency coordination procedures that should be done through ICAO are carried out with the coordination of Directorate General of Civil Aviation by the Authority.

2-)  In case of any harmful electromagnetic interference caused by any system residing in  a neighbouringcountry,  necessary  actions  in  order  to  solve  the  problem  are  taken  by  the Authority.

3-) The operators have to comply with the regulations made by the Authority regarding the frequency assignment and registration and the National Frequency Plan and possible changes to be done in the National Frequency Plan. In order to prevent harmful electromagnetic interference on the operators in Turkey or in the neighbouring countries, the operators have to take all necessary measures defined in national legislation and international agreements  of  which  Turkey  is  a  party.  In  this  context,  the  operator(s)  may  sign  agreements with  other  operator(s)  in  neighbouring  countries  provided  that  they  carry  out  frequency coordination in coordination with the Authority and by having opinion from the Authority.

Withdrawal of Assigned Frequencies and Cancelation


1-) Due  to  technological  progress  and  decisions  made  by  international organizations  that  Turkey  is  a  member  of,  in  case  of  necessity,  the  Authority,  being  in coordination with the related sides, causing no deficiency in national security and intelligence, may withdraw or cancel all or some part;

  • a-) Of  assigned  frequencies  to  operators  and  users  who  are  not  limited  in  quantity  of right of uses,
  • b-) Of  frequency  bands  and  frequencies  assigned  to  Turkish  Armed  Forces  and  Radio and Television Supreme Council,


2-) The withdrawal of frequencies from the operators limited in quantity and have the  right  of  use  is  regulated  in  relevant  tender  specifications  and  in  relevant  certificate  of competency of right of use,

3-) Operators which are  authorized in the scope  of right of use  and are not limited in quantity may demand additional time with their due justifications, on the occasion that if they don’t start to provide service after the one year of the date of authorization. Authority may grant  maximum  of  six  months  of  additional  time  to  the  operator(s).  Authority cancels  the frequencies assigned to the operator if the operator does not start to provide service within the one  year  of  period  beginning  with  the  date  of  authorisation  and  does  not  demand  additional time  or  does  not  start  to  provide  service  within  the  additional  time  provided  that  operator cannot  document  any  force  majeure  reasons.  In  this  case,  the  Authority,  giving  a  reasonable amount of time, sends the decision with reasons regarding the cancelation of the frequencies assigned  to  the  operator.  The  operator  has  to  make  the  necessary  arrangements  due  to  the provisions  in  this  paragraph  within  the  time  period  set  by  the  Authority  regarding  the cancelation.

4-) For the users that have the permission for installation and use of radio equipment, if  the  work  is  not  completedat  the  end  of  the  given  amount  of  time,  including  due  time prolongation, the permission given and the frequencies assigned are both cancelled.

5-)  If  the  operator  or  user  gives  up  the  frequency  usage,  the  frequencies  assigned  are cancelled.

6-) The  Authority  does  not  take  on  any  responsibility  regarding  the  withdrawal  or cancelation of frequencies assigned.

7-)  The  authority  may  reassign  the  frequencies  which  are  withdrawn  or  cancelled  to operators and users in accordance with the relevant legislations.
