UAV Telemetry Frequencies allowed in Australia?

Posted by Brett Glossop on May 31, 2010 at 4:59am

I found some notes at www.acma.gov.au. Does this sound as though UAV telemetry at 900 MHz is allowed in Australia?

 

Are the Arduino devices spread spectrum?

From ACMA:

Frequency bands and power limits for spread spectrum and digital modulation devices

Device

Frequency band (MHz)

Maximum equivalent isotropically radiated power (EIRP)

Frequency hopping transmitters and digital modulation transmitters

915 to 928

1 watt (frequency hopping transmitters must use a minimum of 25 hopping frequencies)

Frequency hopping transmitters

2400 to 2483.5

500 milliwatts (a minimum of 15 hopping frequencies must be used)

 

Thanks in advance,

Brett

    Let's see you are using cellphone right ? it's YOUR device and using 900mhz band :) it totaly legal i think. but if your country still using 900mhz band there can be problems about your transmition.

    btw i cant belive there are places which still using 900mhz band :)

    I asked a similar question in another forum yesterday

     

    What did you find out?

     

    This would be interesting to know

     

    thanks

    I just found out that the Xbee rf tx would be a no go (unless modified) due to it overlapping with GSM mobile phone network.

    From ACMA in Aus:
    Please note: the Australian 900 MHz ISM band is strictly limited to 915 MHz – 928 MHz. Australian mobile telephone carriers operate their GSM mobile telephone networks between 890 MHz and 915 MHz so operating at or below 915 MHz will almost certainly interfere with these services. Severe criminal and civil penalties exist for interfering with licensed services.

    From Xbee datasheet:
    Frequency band: 902 - 928 MHz
    and no C-tick (Aus certification)

    Maybe someone here knows how to modify????
