Frequency Assignments
Assignment Procedure

Frequency assignment is the identification of suitable radio frequencies or channels in accordance with spectrum engineering principles and national regulatory policies. An assignment is supported by a relevant form of licence before the associated radio equipment can be taken into service.

TRCSL assigns frequencies in an efficient and effective manner by employing   a state of the art spectrum management tools that utilize internationally recognized propagation criteria and terrain data base as well as other administrative data bases.

An assignment is normally associated with a radio communication station operating at a specified frequency and location and clearly defined terms and conditions related to maximum power, maximum height and characteristics of the antenna.

The TRCSL is responsible for developing the policies and criteria for the assignment of radio frequency spectrum. Spectrum assignments are made based on following policies.
Process of assigning frequencies is  open, transparent and non -discriminatory for all users;
Issue frequency assignments in a timely manner and in accordance with published assignment criteria, in support of the overall licensing process;
Frequency assignments will be made for all users is in accordance with the National Frequency Allocation Table (NFAT);
Simple administrative processes is employed for the assignment of frequencies where demand for use of spectrum does not exceed supply. The frequencies will be assigned to the users on a first-come first-served basis;
Scarce and highly valued spectrum where demand exceeds supply will be assigned to the users through market-based spectrum management techniques such as auctions, competitive bidding, spectrum trading.
Frequency Co-ordination
Frequency co-ordination is a technical and regulatory process which is intended to remove /mitigate radio frequency interference between different radio systems which utilize the same frequency for operations.

TRCSL carries out national frequency co-ordination to ensure harmonious sharing of frequencies by various users and services. It also performs international and regional frequency co-ordination to avoid harmful interference of frequency users in different administrations.

Frequency assignments, which are capable of causing interference to neighboring countries, are regularly submitted to the ITU’s Radiocommunication Bureau (ITU-R) for purposes of coordination with other countries and then registered in the Master International Frequency Register (MIFR).
