    Sory for my english.
    i think in france and other country we use the CE regulation
    and the power of transmit is less than FCC power
    somebody know if there is different i1 v2 ? one for CE and one for FCC ? and it s hardware ?
    or the difference it s software and how does it works ? release ? gps position ?

    thanks

    Hello

    If you use a iPad or iPhone you can you can skip the restriction and use the legal and complete FCC power of USA changing the region France by EEUU in general iPad settings.

    Best regards
    Fly safe ;)

    Does anyone know whether the maximum legal power in the UK is 100Mw or 250Mw - offcom site seems to say 100Mw & 2.4G....?

    100mW/20bBm maximum EIRP.

    ^^ Thanks for confirming, so the hoohah about transmitter power (V1 / V2) simply has no relevance here in the UK.
    Since 'EIRP' then any sort of directional antenna is definitely off [legal] limits...?

    Once your GO app locates it position the software adjusts manually.

    Correct - totally pointless.
    Not only will a directional higher gain antenna not be legal it is a double whammy since it would also be illegal to alter a fixed antenna 2.4ghz transmitting device in the UK. OFCOM would get the ar*e!

    i make a mesure of the power
    my inspire is 1 v2 (1510)

    the power on the antenne was 15 dbm is about 35 mw
    not big power
    the test was made in labo hf

    ^^ Mmmmmm.... Interesting finding. Then could it be that the software increases TX power up to 100Mw as and when necessary..?

    I have no idea what labo hf is but I would not trust anything other than a test set up in an anachoic chamber using calibrated equipment with no multipath errors.
    Having said that there is nothing unusual about a low rf output reading because OFDM FHSS technology ramps up and down the power as required.
    100mW carrier output when not needed would simply be wasted energy.
    It is the maximum EIRP that is restricted to 100mW/20dBm not a constant.
