2 AFAS – Internal operation
The AFAS unit is a software with access to the internet with
permission to access the TVWS database and the NOC.
2.1 Adding new Base Station (BS)
Prior to deployment of new BS, operator needs to update AFAS
with the BS information, the expected installation location, the radio
capabilities, and the initial frequency which is selected from the database
manually and take into account the known interference in that area. After
adding is done and the BS is active, the AFAS is automatically submitting a
query to TVWS DB for allowed transmission channels for the new BS
(double check that all process is working properly).
After receiving the TVWS DB response, AFAS will check that the
initial frequency is in the allowed list, and in case of reject, it will use the best
frequency selection algorithm and will send a set frequency command to the
BS followed by start transmission command.
Note: In phase 2 of AFAS development, AFAS will send
measurement request to BS in order to verify the freshness of the
environment noise levels which are crucial inputs to the channel selection
algorithm.
