Sub-Gigahertz Band Sensor Radio Network

Data acquisition and control radio sensor network based on a Si446x single-chip programmable transceiver is proposed. Physical layer with GFSK modulation in sub-gigahertz band is considered. Data link layer implementation with generic frame structure for a network, operating in synchronous mode, is presented. Particular attention is paid to the transceiver application in frame address filtering mode and the usage of interrupts.
