Dear Friends,
I have a project for a high school, is needs one remote controller to control two lower power device in school. The transmitted distance is about 500~1000m only, the power of my transmitter is about 300~500mW and the operating battery is 9V battery. Can I use 315MHz carrier frequency without any approval in HK?? (such as, FCC, or......etc)
Thank your very much!!
