It seems like NO is wrong according to Norwegian rules This is how NO currently looks like in wireless-regdb-2011.04.28.tar.bz2 -------------------START------------------- country NO: (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ 40), (N/A, 20) (5250 - 5330 @ 40), (N/A, 20), DFS (5490 - 5710 @ 40), (N/A, 27), DFS --------------------END-------------------- This is what the Norwegian rules say about general usage of frequencies for wi-fi: Note: The following text is a translation from a subsection of the following document written in Norwegian: http://www.lovdata.no/for/sf/sd/xd-20090602-0580.html#7 -------------------------------------START-------------------------------------- (3) the frequency band 5150-5350 MHz is authorized for indoor data transfer including radio-based local area networks (WAS / RLAN) with a maximum radiated power of 200 mW eirp the frequency use defined in the standard EN 301 893 If any other use than indoor use, the average spectral density in the frequency band 5150-5350 MHz is limited to 10 mW / MHz eirp in any 1 MHz range. (4) the frequency band 5470-5725 MHz may be used for data transfer with maximum radiated power of 1 W eirp Maximum average spectral density shall not exceed 50 mW / MHz eirp in any 1 MHz band. The radio equipment shall implement transmit power control (TPC) which provides an average attenuation of at least 3 dB. If TPC is not in use, the maximum allowed radiated power and power density is 3 dB lower than that following the first and second sentence. The radio equipment will use Dynamic Frequency Selection (DFS) as specified in the standard EN 301 893 (5) The frequency bands 5725-5795 MHz and 5815-5850 MHz for data transfer with maximum radiated power of 4 W eirp Maximum average spectral density shall not exceed 200 mW / MHz eirp in any 1 MHz band. The radio equipment shall implement Dynamic Frequency Selection (DFS) as specified in the standard EN 302 502 Radio equipment shall transmit power control (TPC) which provides an average attenuation of at least 3 dB. If TPC is not in use, the maximum allowed radiated power and power density is 3 dB lower than that following the first and second sentence. On the border between Norway and neighboring power density shall not exceed -122.5 dBW / m 2 measured with a reference bandwidth of 1 MHz unless otherwise stated in the coordination agreement. (6) The frequency bands 5725-5795 and 5815-5850 MHz for point-to-point radio links with maximum radiated power of 200 W eirp Maximum permitted power supplied antenna is 1 W. The maximum average spectral density shall not exceed 10 W / MHz eirp in any 1 MHz band. The concept of point-to-point radio links exclude all forms of point-to-multipoint, omnidirectional systems and transmitters send the same information located in the same place (sector antennas). The radio equipment shall implement Dynamic Frequency Selection (DFS) as specified in the standard EN 302 502 On the border between Norway and neighboring power density shall not exceed -122.5 dBW / m 2 measured with a reference bandwidth of 1 MHz unless otherwise stated in the coordination agreement. --------------------------------------END--------------------------------------- Here is the link to google english-translated section mentioned above: http://translate.googleusercontent.com/ ? NwIZhFVA#7 According to that documentation, NO should probably look like this instead: -------------------START------------------- country NO: (2400 - 2483.5 @ 40), (N/A, 20) (5150 - 5350 @ 40), (N/A, 23) (5470 - 5725 @ 40), (N/A, 27), DFS --------------------END-------------------- Question 1: The norwegian laws also says that if TPC is available, then the maximum allowed TX power of the 5470 -> 5725 MHz frequency range changes from 27 dBm to 30 dBm, I don't know how to write that in wireless-regdb. Question 2: The norwegian laws for the 5470 -> 5725 MHz frequency range seem to exceed the European restrictions in 802.11n-2009, I'm guessing that the upper 5725 MHz frequency needs to be decreased to comply with the European restrictions? if so, I'm not sure what frequency it should be decreased to. Question 3: The norwegian documentation also mentions these radio frequencies for wireless data transfer: * 5725 -> 5795 MHz and 5815-5850 MHz: point-to-point radio links * 17,1 -> 17,3 GHz: * 57 -> 66 GHz: Does these belong in the wireless-regdb as well? I hope my limited knowlege doesn't cause anyone unreasonable much work, I'm really trying to get better at this. -Robert Gr?nning (Norway)
