Hello, This question pertians to transmitting data in ISM band (902Mhz-928Mhz or 2.4Ghz band) Is there any limit on the bandwidth allowed to transmit data? Is it "mandatory" that transmitters operating in ISM band use spread spectrum techniques only? Cannot we transmit the data at high date rates in these bands by employing high bandwidth?
