Wavebands

The following table gives a list of all the bands authorized in the world.

The indicated limits correspond to the maximum noted; very often, local legislations of countries impose more restricted limits.

Name	Lower limit	Upper limit	Notes
BF MF HF bands (long, medium and short waves)
2 km	135,7 kHz	137,8 kHz	Band limited to the numerical modes (Morse included) with 1 W PIRE, authorized since the 2007 CAMR.
600-meter band	501 kHz	504 kHz	Used only in Germany, Belgium, Canada, Denmark, the United States, Ireland, Iceland, Norway, Netherlands, Czech Republic, the United Kingdom, Sweden. The upper limit of the band is variable according to the countries.
160-meter band	1 800 kHz	2 000 kHz	Upper band limit variable according to the countries
80-meter band	3 500 kHz	4 000 kHz	Band shared with other services, limits variable according to the countries.
60-meter band	5 200 kHz	5 405 kHz	Used only in the United States, in the United Kingdom, in Norway, in Finland and Iceland with channels inside the band.
40-meter band	7 000 kHz	7 300 kHz	Upper band limit variable according to the countries. The radio hams have a secondary statute until 2009, date on which the range from 7100 Khz to 7200 Khz will be completely allotted to them.
30-meter band	10 100 kHz	10 150 kHz
20-meter band	14 000 kHz	14 350 kHz
17-meter band	18 068 kHz	18 168 kHz
15-meter band	21 000 kHz	21 450 kHz
12-meter band	24 890 kHz	24 990 kHz
10-meter band	28 000 kHz	29 700 kHz

VHF/UHF bands
6-meter band	50,000 MHz	54,000 MHz	Variable limits and restrictions according to the countries
4-meter band	70,000 MHz	70,500 MHz	In certain countries only
2-meter band	144,000 MHz	148,000 MHz	Limited to 146 MHz in area 1.
1,25 m	219,000 MHz	225,000 MHz	Only in area 2.
70 cm	420,000 MHz	450,000 MHz	Restricted from 430 MHz to 440 MHz in area 1 and from 430 MHz to 450 MHz in area 2. On frequency 433 MHz the radio hams have priority and have notable powers of emission so that the domestic facilities without licence and of very small powers are likely to be disturbed.
33 cm	902,000 MHz	928,000 MHz	Only in area 2.
23 cm	1 240,000 MHz	1 325,000 MHz	Upper band limit variable according to the countries
13 cm	2 300,000 MHz	2 450,000 MHz	Variable limits according to the countries. On the frequency 2400 MHz the radio hams have priority and have notable powers of emission so that the domestic facilities Wi-Fi without licence and of very small powers are likely to be disturbed.

6 cm	5,650 GHz	5,925 GHz	Band limits variable according to the countries
3 cm	10,000 GHz	10,500 GHz
12 mm	24,000 GHz	24,250 GHz
6 mm	47,000 GHz	47,200 GHz
4 mm	75,500 GHz	81,000 GHz
