What is the efficiency of the spectrum?
The frequency spectrum
is a limited source and must therefore be used to provide end users with the best possible experience. The spectrum efficiency is defined as the optimized use of a bandwidth or spectrum that allows maximum data transfer with the least possible transmission errors. For example, in cellular networks, this applies to maintaining acceptable service quality, while allowing the maximum number of mobile phone users to access the network simultaneously. There are three main components for spectrum efficiency: economic, technical and functional. Each of the three components contributes to the overall measurement of the spectrum efficiency.
Economic efficiency takes into account the generation of income, profits and a value generated from a limited spectrum source. The assignment of the economic value to the overall measurement of the spectrum efficiency is essential for the effective use of market licensing. It is also important to effectively determining and setting the spectrum price models.
Technical efficiency takes into account the maximum amount of data that fromThere is a source of spectrum. Such factors include a covered geographical area, the volume used and the total bandwidth. Measurement of the technical spectrum is essentially important especially for cell networks, but is still involved in other evaluation of communication spectrum, such as radios.
Functional efficiency determines how well the use of the spectrum source meets the needs of end users, which allows these users to perform tasks such as conversation, both efficiently and efficiently. In addition, it can compare the current state of the source with other potential applications to be functionally determined. If the transport company relies on the ability to communicate immediate communication, it has delivered reliably and cost effectively in constant movement, then such a network requirements may not be compatible with a public network that is usually trying to maximize transport production. Public security and emergency services are other examples where JE measuring functional efficiency essential due to relying on the reliability and speed of a close connection.
Usually the measurement of the spectrum efficiency will take into account all three of these dimensions to determine optimal use. Often, however, different communication media inevitably scored in one area than in the others. For example, mobile radio and mobile services will receive a high -technical spectrum assessment compared to private mobile radios; However, it usually offers more functional efficiency of the spectrum. The overall measurement assessment is a qualitative and quantitative process that includes both technical measurements and feedback from end users.
