What is meant by spectrum allocation?
Spectrum allocation is the process of regulating the use of the electromagnetic spectrum and dividing it among various and sometimes competing organizations and interests.
How is spectrum allocation done?
They are divided into bands based on frequencies (see ‘Radio spectrum’). Mobile phones use two technologies based on different parts of the radio spectrum— GSM (global system for mobile communications) and CDMA (code division multiple access). Most of the radio spectrum is reserved in countries for defence.
What manages the allocation of RF spectrum?
The International Telecommunication Union (ITU) is the part of the United Nations (UN) that manages the use of both the RF Spectrum and space satellites among nation states.
How is radio spectrum divided?
The spectrum is divided into different frequency bands, and each band has been allocated for a specific application ranging from aeronautical and maritime communication to AM and FM radio stations.
Why do we allocate frequency?
Frequency allocation (or spectrum allocation or spectrum management) is the allocation and regulation of the electromagnetic spectrum into radio frequency bands, normally done by governments in most countries.
What are the factors need to be considered to allocate frequency?
Technical factors, predominantly frequency/propagation, and space location must be considered when allocating spectrum.
Why is frequency spectrum important?
Having more spectrum helps operators to deliver this better user experience. In particular, aggregating spectrum into larger downlink carriers raises peak data speeds but also more generally helps to provide the higher average speeds valued by many users.
What is digital spectrum?
A set of radio transmission techniques that vary the timing and frequency of the signal, thereby increasing the transmission’s bandwidth, reducing noise and interference while making the signal harder to detect or intercept.
