Overview of frequency sharing
Abstract
Frequency engineering is the process of sharing spectrum space among many requirements in a manner which attempts to control potential operational interference. In most cases, the point that operational degradation occurs is identified by technical parameters. All frequencies are shared. In the case of the United States Army, the communication requirements exceed all possible spectrum space by approximately 8 times. The individual user of the radio spectrum would like to be unconcerned with sharing. However, this is not practicable for two reasons. First, the user must share his frequency with noise which is intrinsically involved with his system's design and environment. It influences his own design approaches and establishes limiting conditions of performance for the proposed operation. Secondly, the sharing environment forces him to recognize the presence of other users. In the assignment process, sharing is considered in one or more variations of four concepts.
