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.
