Communication systems
Reliable point-to-multipoint embedded RF
A 2.4 GHz embedded network designed around packet integrity, acknowledgements, retry behavior, interface integration, and field validation.

Personal scope
What I owned
- Architected a coordinator-and-node communication model for a point-to-multipoint embedded network.
- Implemented packet integrity, acknowledgements, and automatic retransmission in the embedded protocol.
- Worked across firmware, radio configuration, antenna matching, interface behavior, and system-level EMI investigation.
Engineering approach
How I reasoned about it
- 1
Treat reliability as protocol state, not only as radio signal strength.
- 2
Make packet identity, acknowledgement windows, retry limits, and failure behavior explicit.
- 3
Evaluate firmware, RF path, antenna behavior, power integrity, and interference as one system.
Validation
How the signal was checked
- Packet-level checks for integrity, acknowledgement, retry, and recovery behavior
- Bench and field observation of end-to-end link behavior
- Spectrum and mixed-signal investigation when RF, power, and digital subsystems interacted
