Accredited Persons Conflicting Assignments | ACMA

Accredited Persons Conflicting Assignments

Accredited persons most often use data from the overnight update service as the basis for their assignments. In almost all cases this arrangement is perfectly satisfactory. In bands of particularly high activity, however, such 'non-live' data may lead to two people making conflicting assignments within the same band and region. Both assignments may be entered into RADCOM and the problem may not be realised until an interference situation eventuates. The only way to guarantee that no conflicting assignment has been made is to repeat the coordination process after a spectrum access appears in RADCOM.

The ACMA believes that the potential for such conflicts is small, and as re-coordination requires a substantial additional work load, the ACMA is not prepared to make such a procedure mandatory for either the ACMA assigners or accredited persons. It is therefore up to each accredited person to decide if the risk of conflicting assignments being made justifies the resources expended on repeating the coordination process. Any instances of assignment conflicts that do occur will be managed on a case by case basis, and would generally be resolved on a first-in-time basis.

While re-coordination is the only way to guarantee an absence of conflicting assignments, there are other things accredited persons can do to minimise the potential for problems. Firstly, the most up-to-date data available should be used, particularly in bands of high activity. Such data may be obtained either through the overnight update service or an ASL provided by an area office. Note, however, that because ASL production works on a distributed model, the data obtained from an ASL may be no more up-to-date than the overnight update service (ie it may be up to 24 hours old).

Secondly, the assignment should be provided to the ACMA for entry into RADCOM as soon as it is completed. An assignment may be 'held' on RADCOM for ten working days to allow time for the submission of a licence application (see section below for further information regarding the 'hold' policy for assigned frequencies). A charge will only be imposed for holding an assignment where an application is not submitted in the ten working day period.

Important information regarding the 'hold' policy for assigned frequencies

The ACMA policy of 'holding' a frequency for up to 10 working days following the lodgement of a Frequency Assignment Certificate (FAC) form R110 [PDF or Word] is simply intended to assist with frequency coordination. A held frequency is not protected from subsequent applications on the Application for apparatus licence(s) (R057) form. Should a validly completed application be received by the ACMA before the 10 day period has expired, that application would take precedence over the FAC and the frequency that has been 'held'.

Applications for apparatus licences are made under section 99 of the Radiocommunications Act 1992 (the Act), and should be made using approved form R057.

While the FACs are referred to in section 100(4A) of the Act, they do not constitute an application under section 99. The FAC is not an approved application form. Rather, section 100(4A) merely permits the ACMA to take the FAC into account when deciding whether to issue an apparatus licence.

Experience has proven that the potential for competing assignments is very low. However, a practical way to secure a particular frequency is to lodge the R057 application at the same time as the FAC. To assist in this process, the declaration on form R057 allows an agent, such as an accredited person, to sign on behalf of the applicant.
