Welcome. CCA, Chennai 10 th October 2007. Radio Frequency spectrum. Radio frequency spectrum and satellite orbits are limited natural resources. Radio frequencies are arbitrarily confined between 3 kHz and 3000 GHz. Do not respect or obey international geographical boundaries.

Governments of India constituted the Wireless Planning and Coordination Branch (subsequently re-designated as Wireless Planning & Coordination Wing) in the year 1952 vide Ministry of Communications (re-designated as Ministry of Communications & I.T.) order No.1-E (5)/52 dated the 8th October, 1952 to deal with all matters related to radiocommunication services in India. The functions of this Branch, (subsequently changed to Wing), were also identified:
- Spectrum be utilized efficiently, rationally economically and optimally;
- Need for a transparent process of allocation of frequency spectrum.
- The NFAP forms the basis for development and manufacturing
of wireless equipment and spectrum utilisation in the country;
- NFAP-2002 is a public document containing detailed information regarding allocation of frequency bands for various services, without including security information;
- Draft NFAP-2005 is placed on WPC Wing website “www.wpc.dot.gov.in”.
GSM 900 890-915 MHz paired with 935-960 MHz
GSM 1800 1710-1785 MHz paired with 1805-1880 MHz
CDMA 800 824-844 MHz paired with 869-889 MHz
Cor-DECT 1880-1900 MHz (TDD - unpaired)
IMT 2000 1920–1980 MHz paired with 2110–2170 MHz
(3G) 2010 – 2025 MHz (TDD – unpaired)
* Under Revision
Spectrum Charge = M x W x C
Where “M” = 1200 for MW link upto 5 kms
= 2400 for MW link above 5 kms and upto 25 kms
= 4800 for MW link above 25 kms and upto 60 kms
= 9000 for MW link above 60 kms and upto 120 kms
Where “W” = 30 for adjacent channel separation of 2 MHz
= 60 for adjacent channel separation above 2 MHz and upto 7 MHz
= 120 for adjacent channel separation above 7 MHz and upto 28 MHz
Where “C” = Number of RF channels used (2 for duplex network)
