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


Technology Comparison

-90 dBm -100 dBm -148 dBm -117 dBm -126 dBm

100 m 200 m 15 km

Low High

168 dB

90 months 18 months >100 months 36-60 months


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)

What is LoRaTM- Modulation


LoRa TM Coverage Test

Coverage map from a single

gateway/concentrator located on

Cisco Webex building in San Jose

>20miles to San Bruno

A conservative 1 mile radius

allows for in-building

penetration even at

the edges

7 Gateways cover all

of lower Manhattan

Longest Range Coverage !


LoRa TM Technology Benefits
