A sada mali izvodi iz: Article 5 of the ITU Radio Regulations
5.138 The following bands: 6765-6795 kHz (centre frequency 6780 kHz), 433.05-434.79 MHz (centre frequency 433.92 MHz) in Region 1 except in the countries mentioned in No. 5.280, 61-61.5 GHz (centre frequency 61.25 GHz), 122-123 GHz (centre frequency 122.5 GHz), and 244-246 GHz (centre frequency 245 GHz) are designated for industrial, scientific and medical (ISM) applications. The use of these frequency bands for ISM applications shall be subject to special authorization by the administration concerned, in agreement with other administrations whose radiocommunication services might be affected. In applying this provision, administrations shall have due regard to the latest relevant ITU-R Recommendations.
5.150 The following bands: 13553-13567 kHz (centre frequency 13560 kHz), 26957-27283 kHz (centre frequency 27120 kHz), 40.66-40.70 MHz (centre frequency 40.68 MHz), 902-928 MHz in Region 2 (centre frequency 915 MHz), 2400-2500 MHz (centre frequency 2450 MHz), 5725-5875 MHz (centre frequency 5800 MHz), and 24-24.25 GHz (centre frequency 24.125 GHz) are also designated for industrial, scientific and medical (ISM) applications. Radiocommunication services operating within these bands must accept harmful interference which may be caused by these applications. ISM equipment operating in these bands is subject to the provisions of No. 15.13.
5.280 - In Germany, Austria, Bosnia and Herzegovina, Croatia, The Former Yugoslav Republic of Macedonia, Liechtenstein, Portugal, Slovenia, Switzerland and Yugoslavia, the band 433.05 - 434.79 MHz (centre frequency 433.92MHz) is designated for industrial, scientific and medical (ISM) applications. Radiocommunications services of these countries operating within this band must accept harmful interference which may be caused by those applications. ISM equipment operating in this band is subject to the provisions of No. S15.13.

S15.13 Administrations shall take all practicable and necessary steps to ensure that radiation from equipment used for industrial, scientific and medical applications is minimal and that, outside the bands designated for use by this equipment, radiation from such equipment is at a level that does not cause harmful interference to a radiocommunication service and, in particular, to a radionavigation or any other safety service operating in accordance with the provisions of these Regulations.

U svakom slucaju, koga vise interesuje da cita ima na
www.itu.int da se pretplati :) pa neka cita hiljade i hiljade stranica preporuka... interesantna je opcija na CD-u jer moze da se pretrazuje kada ti zatreba... :) A i salju ti redovno update ako si pretplacen :)
No ono sto se odmah vidi je da 915Mhz ne pije vodu u evropi.. i druga bitna stvar... u svakom slucaju ti treba misljenje nadleznog ministarstva ili agencije. Onda oni izdaju "Misljenje Nr. 11244-545-45" u kome ti kazu da je bla bla u skladu sa frekventim planom razvoja RS i da bla bla firma moze da koristi blabla... na sledecim relacijama i tackama bla bla...
Skoro svaka zemlja ima drugacija pravila ponasanja u ovoj oblasti i to je dozvoljeno lokalnoj samoupravi da odredi:)) pardon.. drzavi :)
Zakukuljena je ova oblast :) Treba mnogo zivaca da sve bude regularno.... u svakom slucaju.. oprema koja radi na 900Mhz nije skupa, lako se nabavlja, ima dosta proizvodjaca jer je u Regionu 2 dozvoljena i koristi se, savrseno radi (probao u nekoj drugoj zemlji), pa ako ko uspe da u nadleznom ministarstvu dobije pozitivno misljenje povodom koristenja 915Mhz napravice stvarno revoluciju...
