The AutoLog WSN radio modem series (photo) is suitable for stand-alone wireless data applications or for integration into OEM products. A discrete component RF stage is used to give better performance than would be possible using the simpler “single chip” solutions found in other low-cost designs, says the manufacturer. VHF (138–225 MHz), UHF (406–512 MHz) and 869MHz (863–870 MHz) versions of the AutoLog WSN are available for simplex or half-duplex operation. The device has been optimized, through the use of advanced digital-signal processing (DSP) technology, for reliability and low current consumption, making it especially suitable for operation on remote sites without main power. — FF-Automation Py, Vantaa, Finland
