SRI's standard communications product line addresses both satellite and private land mobile data telemetry markets. The designs conform to a wide variety of standards and requirements, including IRIG, SGLS, STDN, AFSCN, FCC, ETSI, general MIL-STD’s and others. The products incorporate a multitude of modulation waveforms (PSK, FSK, AM, PM, FM, PM/PSK, FM/FSK ...) with a wide range of data rates. The RF portion of these designs covers 130 to 500 MHz for land mobile and 1.7 to 2.4 GHz for satellite telemetry, but can be modularly adapted for user specific frequency bands of interest.

Previous custom development efforts have addressed over-the-air frequency ranges covering HF to SHF, data rates from 50 bps up to 40 Mbps, a variety of advanced signal modulation waveforms, and have incorporated such capabilities as direct sequence spread spectrum, frequency hopping, and various coding formats (Reed-Solomon, BCH, convolutional, ...). SRI can produce fully documented product designs which customers then manufacture themselves, or enter into exclusive manufacturing agreements for custom and/or proprietary designs.
