Techniques for Assessing the Specteum Impact of Future Systems

The length of the average system development cycle is such that the question of spectrum impact must be examined long before the actual operational environment can be clearly defined. The necessity for early evaluation of spectrum availability and environment compatibility causes special analysis problems for the system planner. He must locate and assemble data which will define the expected usage of the spectrum at some future date. He must then assess how that usage will affect the prospects of his system, even though he may not know specifically how his system will be ultimately deployed in the environment. If his assessment is negative, then he must develop viable alternatives or discontinue the development.
