CC1101: 902-928MHz FCC maximum power output when using OOK or FSK.

Hi Zebryk,

If FHSS or a digital modulation technique that gives a 6dB bandwidth of 500 kHz is not used FCC 15.249 restricts output power to 50 mV/m at
3 meters distance (approximately -1 dBm EIRP).

DN006 - CC11xx Settings for FCC 15.247 Solutions gives an overview of FSK settings that could be used to achieve a greater output power without the need of FHSS.

Hi,

What might that be in Pout (dBm) fed into a half wave dipole?

This is for developing a Hi-Fi “Intercom” for Pro-Audio applications.

The duty cycle or time-on-air could be virtually continuous.

Would this be permitted when using the method shown in DN006?

Would another chip be better having a higher maximum data rate?

Is Spread-Spectrum essentially required? Not a cost sensitive application.)

Also, this is desired to be full duplex. (Using (2) transceivers.)

Could this be done in a pocket sized device without a Duplexer.

Thanks,

Hi Zebryk,

That will depend on the exact antenna. Taking the typical value for a dipole of 2.15 dBi, that would be approximately -3.15 dBm.

before answering your other questions, about what effective data rate would your audio application require? (The audio bit rate)

Diego,

The want is 1Mbps. Almost doing it now at 650Kbps.

Our big challenge is getting the latency down to 5mS.

Peace,
