1. RM1101-USB-232 wireless module, wireless communication, TI's high performance CC1101 chip, a USB interface, serial data radio module, designed specifically for the host computer device wireless data trans applications, general wokds RM1100-232 TTL digital trans module for wireless data use, mainly used in the lower hine (MCU) with the host
2.Computer (PC computer end) , we also can use two RM1101-USB-232 module, wireless communication between two PC. Module external interface for USB, internal virtual serial port, the development and application is more easy than USB2.0 .
Compare CC1101 and CC1100 : 
Improve stray response; 
The more closely phase noise better improve adjacent word power (ACP) performance; 
Saturation level higher input; 
Higher efficiency of power output 
The expansion of the continuous frequency band, 
CC1100:400-464 MHz and 800-928 MHz 
CC1101:387-464 MHz and 779-928 MHz
– Low power module, biggest trans rate:10 mW . 
– Work In 433 MHz ,free ISM band,use without license. 
– High anti-interference ability and low bit error rate, based on FSK modulation method, Improve the ability of Data random anti-interference and burst anti-interference ability 
– Support transparent data trans and DL / 645 statute. Provide transparent data interface, can adapt to any standard or the standard user agreement. Automatic filtering out the air from the false data (Receiver is Transmitter); 
– Communication software support wireless meter reading system DL / 645 statute. 
– Biggest programmable channel: 256 (20 M frequency band).There is at least 256 channel in accordance with the 200 KHz interval frequency ; 
– Large data buffer. Interface baud rate is equal to the air effective baud rate, provide 3 kinds of user can choose baud rate: 4800, 9600, 19200 BPS (interface can be set up to the highest rate of 19200 BPS); – Data format for 8 N1/8 E1/8 O1 user defined, but trans for the longest 30 bytes of data frame, user programmable more flexible. 
– Intelligence data control, users need not prepare extra procedures.  Even if is half duplex communication, users also need not prepare extra program, as long as the/out the data from the interface can be, and other such as air charge/hair conversion, control operation, RM-1101 232 module automatically. 
– The model with high quality silver spring antenna, competitive. Also can be equipped with a variety of other gain rubber antenna, chuck antennas, meet the practical needs. 
– Wireless module nominal maximum communication distance refers to the distance in the communication between the microcontroller and the microcontroller to achieve one end or both when connected to the PC, due to the the computer radiation of RF electromagnetic interference, distance will greatly shortencommunication, such as between the RF1100-232 module microcontroller 200 meters connected to the PC when generally only reach around 100 meters .
