The 250 Series RF transceiver module from Linx Technologies (Boulder, CO) is designed for reliable bi-directional transfer of digital data over distances of up to 4 miles (6.4 km), line of sight. Operating in the 902 to 928 MHz ISM (Industrial Scientific and Medical) frequency band, the transceiver module is capable of generating +23.5 dBm into a 50-ohm load and achieves an outstanding typical sensitivity of –105 dBm. This high output power gives the module remarkable range and also helps overcome noisy environments at shorter ranges. Regulations in the country of operation dictate the maximum legal output power, so the final system range may be less depending on the country of operation. Features include:
- Frequency Hopping Spread Spectrum (FHSS) protocol.
- Universal Asynchronous Receiver Transmitter (UART) serial interface that can be connected directly to microcontrollers, RS-232, RS-485 converters or USB adaptors.
- Carrier Sense Multiple Access (CSMA) algorithm assures the channel is clear before sending data.
