The calculations are complicated, and rely on the national DTT coverage data - the UK DTT tables alone (in uncompressed form) are expected to be many GBs in size. In some jurisdictions the calculations also depend on frequently updated tables of other primary users. It simply wouldn't scale for every "master device" to contain that data, nor keep them up to date. Furthermore, the telecoms regulators typically only permit contracted (or licensed) database operators to have access to this raw data, perform the calculations, and subsequently assign frequencies and power levels to devices.
