FCC 15.247 Compliant Long Range Mode Reference Design with CC1120 High Performance RF Transceiver


This TI design provides a software example which implements a frequency hopping driver for the CC112x and CC1200 family of devices. The driver is written to enable users to make IoT wireless applications that are compliant with the FCC part 15.247 frequency hopping system: also allowing long range to be achieved.

  • Longest range is achieved by utilizing the FCC 15.247 frequency hopping for the operation of unlicensed wireless devices in the 902-928MHz ISM band that allows up to 30dBm (1 watt) maximum output powerLowest transmit side power is achieved through the asynchronous features of the fast scanning receiver allowing the transmitters to remain in low power sleep modesMaximum robustness is achieved through utilizing frequency diversity and time diversity in the communication protocol
