SI32193-A-FM1R is an integrated digital wireless radio modem developed by Silicon Labs. This radio modem has been designed for long- range industrial communication, providing higher performance and greater reliability than traditional radio modems. SI32193-A-FM1R operates at 800 MHz, which is in the industrial, scientific, and medical (ISM) bands with both frequency shift keying (FSK) and orthogonal frequency division multiplexing (OFDM) modulations.

The SI32193-A-FM1R is suitable for many applications, including wireless point-to-point, point-to-multipoint, and wireless mesh networking. It is an ideal solution for wireless data acquisition, machine-to-machine (M2M) applications, and remote monitoring and control systems. The radio includes an integrated microcontroller that is programmable with the Silicon Labs platform. This integrated microcontroller enables rich, complex software applications.

The SI32193-A-FM1R has several features designed to reduce costs and simplify designs. These include a complete menu-driven command set; low power consumption; a smaller form factor; and high payload bit rates with maximum range up to 8 km. Also, the radio modem integrates field-programmable gate arrays (FPGAs) and digital signal processors (DSPs) to increase the performance of communications links. Additionally, it provides frequency agility, robustness, superior range, and modulation support.

The working principle of the SI32193-A-FM1R radio modem utilizes Frequency-Shift Keying (FSK) for simple transmission and reception of data. By changing the frequencies at which the signal is sent, it is possible to send binary data more efficiently. The frequency ranges where the FSK signals are transmitted are modulated and the receiving radio modem determines the demodulation in order to receive the data. The SI32193-A-FM1R also supports Orthogonal Frequency Division Multiplexing (OFDM). OFDM is a modulation technique used for digital data transmission which separates data into multiple parallel channels by using multiple precisely-spaced subcarrier frequencies. With OFDM, multiple data streams can be sent simultaneously over a single channel and there is no need to retransmit the signal or re-synchronize it at the receiver. This increases the throughput of the radio modem.

The SI32193-A-FM1R radio modem provides reliable and secure long-range wireless communications in a variety of industrial and commercial applications. With high payload bit rates and long range, it is an ideal solution for wireless data acquisition, M2M applications, and remote monitoring and control systems. It is easy to set up and configure, and provides high performance and robustness.
