Terrestrial audio and video wireless links are used for a number of PMSE applications. The range of applications covered by PMSE spans from theatrical productions and corporate events to various levels of broadcasting contribution activities. PMSE includes services ancillary to programme making (SAP) and broadcasting (SAB) and the links of the narrower category known as Electronic News Gathering and Outside Broadcasting (ENG/OB). For a more detailed description of PMSE, please refer to ECC Report 204.

It is important to note that a number of PMSE uses, in particular those of News Gathering, happen at unpredictable times and locations and necessitate a very rapid response time. In such cases, it is very important that the delay and the procedures for frequency co-ordination and licensing are limited to the minimum. On the other hand, some of the PMSE uses, such as Outside Broadcasting are normally planned in advance of an event. Frequency assignments for such events may take longer to coordinate, in particular when frequencies have to be “borrowed” from other users of radio spectrum because the spectrum demand exceeds the availability of spectrum allocated to PMSE. Additional information on PMSE licensing at special events and other regulatory aspects may be found in ECC Report 44.

The use of PMSE equipment may not be fully harmonised across the CEPT countries due to divergent national frequency plans and differing PMSE requirements. This Recommendation therefore pursues the concept of tuning ranges, where the term “tuning range” for PMSE means a range of frequencies over which radio equipment is envisaged to be capable of operating; within this tuning range the use in any one country of radio equipment will be limited to the range of frequencies identified nationally (if any) within that country for PMSE, and will be operated in accordance with the related national regulatory conditions and requirements. Within each tuning range, CEPT countries may assign specific sub-bands or particular frequencies for PMSE links subject to availability, actual demand and sharing arrangements with primary services using those bands. Ideally, PMSE equipment should be capable of being operated within the whole tuning range and even beyond in order to provide flexibility for operation in different countries.

When considering the spectrum identified for use by PMSE on a tuning range basis, it can appear that there is a large amount of spectrum available. However, PMSE has always shared spectrum with a wide range of services and to manage use, individual licenses can be issued for a specific use on a specific date and at a specific location. The sharing conditions in a given country depend on the licence given to the new service. The available spectrum within the tuning ranges in any particular country is determined on a national basis; each tuning range may be wholly, partially or not available on a given day, in a given location, in a given country.
