Certifications
Radiocommunications Agency Netherlands
LSA is incorporated in the regular process of the Radiocommunications Agency Netherlands. It is compulsory for the PMSE sector to use the LSA booking system in the 2.3-2.4 GHz band. This obligation is incorporated in the licenses of PMSE users in this band.
Ofcom UK
White Space Devices (WSD) operation in TVWS will be controlled by White Space Databases (WSDB) qualified by Ofcom to provide spectrum information services to WSDs. A WSD will need to contact a WSDB, which will respond to the WSD with a set of operational parameters including the frequencies and maximum powers at which the WSD can transmit. Ofcom’s arrangements with WSDBs will include requirements setting out how those operational parameters should be calculated to meet Ofcom’s objective of ensuring a low probability of harmful interference to existing users of the band and services adjacent to the band.
WSDBs will need to go through a process of qualification in which Ofcom tests a database to gain assurance that the database is capable of operating in accordance with the terms on which it has been appointed. Hence, a key component of the qualification process will be testing that the database is capable of implementing Ofcom’s coexistence framework. In order to perform the necessary calculations that result in a set of operational parameters for a particular WSD, Ofcom will provide a WSDB with certain data.
Communications Authority of Kenya
The operation of white space devices will be controlled by databases qualified by the Authority. A WSD will need to contact a database, which will respond to the WSD with a set of operational parameters including the frequencies and maximum powers at which the WSD can transmit. The Authority’s arrangements with geolocation database providers will include a detailed methodology to calculate coexistence parameters that meets the Authority’s objective of ensuring a low probability of harmful interference to primary users of the target band and services adjacent to the band.
The database providers will undergo a qualification process through which the Authority will determine their compliance with rules for the operation of geolocation databases for spectrum sharing. The main objective of the qualification process is to test whether the database is capable of implementing the Authority’s coexistence rules. In order to perform the necessary calculations that result in a set of operational parameters for a particular WSD, the Authority will provide a database with data on active DTT Transmissions.
This data will include designated DTT transmitter locations, active channels, maximum radiated power and other parameters described in the rules. The database will compute transmission parameters for use by WSDs that will ensure a low probability of harmful interference to DTT reception and guarantee adherence to Kenya’s international obligations regarding neighbouring countries use of the UHF band.
