Summary

I am looking for an experienced RF/embedded systems engineer with expertise in proprietary 2.4 GHz wireless protocols, RF spectrum analysis, frequency hopping systems, and packet-level communications. I need an independent technical analysis of a wireless medical device system consisting of a remote controller and multiple wireless receiver units. The objective is to determine how the system actually operates, not to support any predetermined conclusion. Tasks include: • Review technical documentation and communication specifications. • Analyze RF behavior using spectrum analyzer data. • Determine actual operating frequencies and hopping behavior. • Determine whether receiver units share frequencies or use dedicated frequencies. • Determine whether receiver selection changes RF transmission behavior or only affects packet contents/identifiers. • Analyze packet structure, UID/device identification logic, synchronization behavior, and communication flow. • Review firmware/source code if available. • Create diagrams showing: * RF architecture * transmit/receive flow * packet flow * frequency usage * device selection process • Produce a written technical report explaining the actual communication architecture. Important: The analysis must be independent and objective. I am not looking for someone to advocate a position. I need a technically accurate description of how the system operates based on evidence, testing, and engineering analysis.
