Notification of the National Telecommunications Commission
On Radio Frequency Plan
Regarding Radio Frequency Plan for Fixed Service in the Frequency Band of 6.7 GHz
_________________________
Whereas it is deemed expedient to specify the radio frequency plan to support
consideration of radio frequency assignment, pursuant to Section 51 (1) of the Act on
Organization to Assign Radio Frequency and to Regulate the Broadcasting and
Telecommunication Services B.E. 2543 (2000), the N ational Telecommunications Commission
hereby issues the Notification on Radio Frequency Plan regarding Radio Frequency Plan for
Fixed Service in the Frequency Band of 6.7 GHz as detailed in the Radio Frequency Plan No.
NTC FP 107-2550 appended hereto.
This Notification shall take effect on and from the day after the date of its publication
in the Royal Gazette.
Announced on the 20th
day of September B.E. 2550 (2007)
General Choochart Promphrasid
Chairm an of the National Telecommunications Commission

Radio Frequency Plan
For Fixed Service in the Frequency Band of 6.7 GHz.
1. ScopeThis radio frequency plan determines channels and conditions on the use of frequency
channels for fixed service in the frequency band of 6.7 GHz based on the Radio Regulations and
the Recommendations of the International Telecommunication Union (ITU -R Recommendations).
2. Channeling ArrangementsThe channeling arrangements in the frequency band of6.7 GHz based on the ITU-R
F. 384-9 recommendations 1 and 2 are as follows:
2.1 Channeling arrangement in the 6.7 GHz band with a frequency range of 6430-7110 MHz;
2.2 Channeling arrangement expressed by the following relationships:
For systems with a carrier spacing of 20 MHz:
Lower half of the band fn =f0 350 + 20 n
Upper half of the band fn =f0 - 10 + 20 n
n = 1, 2, 3,, 16
f0 = 6770 MHz
For systems with a carrier spacing of 40 MHz:
Lower half of the band fn =f0 350 + 40n
Upper half of the band fn =f0 - 10 + 40 n
n = 1, 2, 3,, 8
f0 = 6770 MHz
Where:
f0 be the frequency at the centre of the 6.7 GHz band (6430 - 7110 MHz).
fn,fn be the centre frequency of radio -frequency channel in the lower -upper
half of the band channel n.
