Wireless modulation technology
Physical (PHY) layer for long range communications
Operates in the license-free ISM bands all around the world
• 433, 868, 915 Mhz
• Regulated (power, duty-cycle, bandwidth) E.g: EU: 0.1% or 1% per sub-band duty-cycle limitation (per hour)
Sensitivity: -142 dBm
Link budget (EU): 156 dB
We’ll use LoRa
ISM Regulation ISM worldwide regulation 7
