The League also says that the ITS proposal and the FCC decision to deploy unlicensed National Information Infrastructure devices in the band could render 175 MHZ of spectrum in the 5.8 GHz range significantly less useful to hams. FCC ok's U-NII devices in the 5 GHz frequency range. The FCC has amended its rules to add to the flexibility and capability of Unlicensed National Information Infrastructure or U-NII operations. This says the FCC without causing an increase in harmful interference to those operations currently sharing the same spectrum. Specifically, on June 17th the Commission amended Part 15 of the rules to permit fixed, point to point U-NII devices in the 5.725 to 5.825 GHz band.
Transmitters can operate with one watt maximum output power.
They can also use directional antennas of up to 23 db of gain. According to Art Feller, W4ART, hams experiencing interference from what appears to be a Guatemalan land mobile station should gather as much information as possible about the intruder. This should include the call sign, frequency, emission type, and if possible, the content of its transmission. Also, note the date, time, and callsigns of the other amateur station you are attempting to communicate with. Report all of this information to your national IARU member society so that a formal complaint may be lodged through appropriate diplomatic channels.
