LoRa Airtime, Duty Cycle & Battery Cost: Spreading Factor Planner
Compare SF7–SF12 airtime, bit rate, link gain, hourly duty budget and battery cost per message. Enter your regional limit and device currents; optionally estimate ALOHA overlap.
Compare SF7–SF12 airtime, bit rate, link gain, hourly duty budget and battery cost per message. Enter your regional limit and device currents; optionally estimate ALOHA overlap.
Estimate LoRa link margin, Fresnel clearance and ridge diffraction. Compare free space with Hata models and check dated regional power and airtime presets.
Estimate inference and training VRAM, maximum sequence length and microbatch, runtime and cost for full fine-tuning, LoRA and QLoRA. Compare GPU sharding, checkpointing and editable MFU assumptions.
