Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1]
Examples: Frequency allocation band plans decided by standardization bodies, by national frequency authorities and in frequency resource auctions. Deployment of base station sites (or broadcasting transmitter site) Antenna heights; Channel frequency plans; Sector antenna directions; Selection of modulation and channel coding parameters
As a matter of convention, the ITU divides the radio spectrum into 12 bands, each beginning at a wavelength which is a power of ten (10 n) metres, with corresponding frequency of 3×10 8−n hertz, and each covering a decade of frequency or wavelength. Each of these bands has a traditional name.
Spectrum management is a growing problem due to the growing number of spectrum uses. [6] Uses include: over-the-air broadcasting, (which started in 1920); government and research uses (which include defense, public safety—maritime, air, police—resource management, transport, and radio astronomy); commercial services to the public (including voice, data, home networking); and industrial ...
The allocation might be primary, secondary, exclusive, and shared. primary allocation: is indicated by writing in capital letters (see example below) secondary allocation: is indicated by small letters (see example below) exclusive or shared utilization: is within the responsibility of national administrations; Example of frequency allocation
The allocation of radio frequencies is provided according to Article 5 of the ITU Radio Regulations (edition 2012). [ 3 ] In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is with-in the ...
Bandwidth allocation is the process of assigning radio frequencies to different applications. The radio spectrum is a finite resource, which means there is great need ...
In Canada, the United States, Mexico, the Bahamas, etc., there are 101 FM channels numbered from 200 (center frequency 87.9 MHz) to 300 (center frequency 107.9 MHz), though these numbers are rarely used outside the fields of radio engineering and government. The center frequencies of the FM channels are spaced in increments of 200 kHz.
