Free ISM Band in China

hi there, just wanted to know if 900 MHz & 2,4 GHz bands are free to use in China.

Thanks in advance !

I just know the 900M band occupied by GSM mobile communication in China.

yes, 900Mhz is occupy by gsm, and 2.4GHz is free.

hi all, thanks for your answers.
I search for an oficial chinese site where i can find some info about sprectrum allocations but i couldn′t find one. If you have a link please send it over (english or spanish would be great )
well, thanks in advance mates.

I guess the last pages of the following site about the frequency planning in china would be somewhat helpful.

But I think maybe you can write to the office directly.
Good luck.
