32khz Crystal Thermal Drift Characteristics in Sub-GHz Nodes
Uncompensated 32kHz tuning-fork crystal thermal drift expands sub-GHz node receive guard windows, consuming battery capacity during sleeping cycles.
Receiver Guard Time Expansion Mathematics under Non Linear Thermal Sleep Clock Drift
Integrating instantaneous frequency offset polynomials over sleep intervals expands receiver guard windows accurately without wasting battery capacity in low power nodes.
Mitigating Multi-Year Cumulative Phase Error Propagation in Unpowered Duty Cycle Aggregation Buckets
Persisting polynomial thermal compensations in non-volatile registers maintains multi-year radio synchronization without exceeding low-power current limits.
