Examples
Check FCC Part 15 limits
→ Returns 43.5 dBuV/m @ 3m (quasi-peak)
Compare FCC vs CISPR
→ Shows both limits with distance correction notes
Check restricted bands
→ Yes - aeronautical emergency frequency
Look up LTE band
→ UL: 2500-2570 MHz, DL: 2620-2690 MHz (FDD)
Find carrier bands
→ Low: n71, Mid: n41/n77, mmWave: n260/n261
Frequency to band lookup
→ LTE Band 42, NR n77, NR n78
Check ISM bands
→ Yes - 2400-2500 MHz ISM band
