What is LoRaTM Technology?
LoRaTM is a proprietary wireless technology
developed by Semtech
Enable long range coverage and low power At +14dbm output power, 868MHz:
Up to 5km range in urban environment, up to 15km suburban
>10 year battery life capability
Robust communication Not susceptible to interference from Wi-Fi, Bluetooth, GSM, LTE, etc
Improved network capacity Connect more nodes, 100k to 300k nodes
High accuracy localization and ranging capability
(not available now) Modulation format permits high accuracy localization
Not RSSI based and accounts for multi-path and fading
Permits high value additional features

LoRa TM uses „Chirp‟ spread spectrum modulation
Innovative & cost sensitive implementation
Demodulate signals below the noise floor, improving sensitivity by ~20dB
Robust against interference, noise, and jamming
Multiples signals can occupy the same channel (CDMA)
Tolerant to frequency offsets (unlike DSSS)
