LoRa vs. LoRaWAN
Information – Property of Semtech Corporation 6 11/8/2017
LoRa – ”Long Range” is the physical layer, like FSK, FM, etc. It’s theData modulated by the radio and transmitted from the antenna. The spread spectrum
modulation have to be received by a LoRa enabled receiver to be converted back to serial data again.
Possible to use in Frequencies from ~138MHz to >1GHz. (SX1272, SX1276) Modulation BW, 125kHz, 250kHz, 500kHz. (SX1272, SX1276) Several transmissions possible with different spreading factors SF7-SF12 within the same
frequency band. The radios SX1272 and SX1276 can still use FSK,
GFSK, OOK.. Etc. LoRa and FLRC radio at 2.4GHz (SX1280, SX1281).
• The SX1280 can also do ranging P2P. Energy efficient Star Network Topology

LoRa vs. LoRaWAN
LoRaWAN – the protocol, the MAC layer, like BLE, WiFi etc. LoRaWAN™ defines the communication protocol and system architecture for the
network Several transmissions at different spreading factors within the same frequency band.
• In EU (ETSI) LoRaWAN uses 10 band in 867MHz – 869MHz at 125kHz BW with SF7- SF12 + one FSK. – Linkbudget: 155dB
• In North America, (FCC) LoRaWAN uses in 902 - 928MHz up to +30dBm. +20dBm is sufficient. – Uplink: 64x125kHz + 8x500kHz (up to +30dBm) – Uplink Linkbudget: 154dB – Downlink: 8x500kHz (up to +27dBm) – Downlink Linkbudget: 157dB
LoRaWAN - values
Resilliant communication Bidirectionality and is symmetrical. High Security Easy commissioning (in manufacturing or OTA) GeoLocation without GPS The Ecosystem is growing Private vs. Public, no difference in arcitecture. ADR – Adaptive Data Rates Easy Scalability No need for TCXO with LoRaWAN (as in narrow-band)
