scope:

The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable. The present document applies to digital equipment operating on radio frequencies between 1 785 MHz and 1 800 MHz. The present document does not preclude any digital FDMA modulation technique, provided that the modulation spectrum lies within the standardized spectral mask.
