This application report describes a 2.4-GHz anti-jamming frequency-hopping system

　　consisting of a designated Transmitter and Receiver， each with distinct functions to

　　avoid RF-channel interference. The Transmitter board emulates the control device

　?。╡.g.， remote control） by sending commands to be processed on the Receiver side

　?。╡.g.， TV， stereo， set top box， or gaming console）。 Since many popular consumer

　　devices use the 2.4-GHz RF spectrum （e.g.， cordless phones， wireless routers，

　　microwaves， and PC/Bluetooth? accessories）， these systems need to implement a

　　proprietary frequency-hopping scheme in the event that the channel being used by the

　　Transmitter/Receiver pair is already being used by other wireless systems in the

　　vicinity. The specific radio device used for this demo is the TI CC2500 （2.4 GHz） RF

　　transceiver module. The TI portfolio also includes the CC1100 RF transceiver

　　（315/433/868/915-MHz ISM/SRD bands）， which shares a common set of configuration

　　registers as those used in the CC2500. This makes it easy to switch between these two

　　RF transceiver devices， so the radio-specific portion of this demo can be used for both

　　types of TI CCxxxx devices
