What is the primary difference between LoRa and LoRaWAN?

ALoRa is the modulation method and LoRaWAN implements the higher network layers

BLoRa Is used for communicating across the Internet and LoRaWAN is used only on the local link

CLoRa uses RF and LoRaWAN uses light-based communications

DLoRaWAN is the Physical Layer and LoRa is the Transport Layer

Show Suggested Answer

Suggested Answer: B

LoRa:This refers to the underlying radio modulation technique using Chirp Spread Spectrum (CSS). It defines how data is physically encoded onto the wireless signal.

LoRaWAN:This is the network protocol built on top of LoRa. It manages device communication, network topology, and aspects like security. It operates at the MAC sublayer of the Data Link layer (Layer 2) of the OSI model

LoRa vs. LoRaWAN:Key takeaway is that LoRa is the physical layer technology, while LoRaWAN adds the networking layer for management.

As a LoRa enthusiast, I can confidently say that option A is the correct answer. LoRa is the physical layer, and LoRaWAN is the higher-level protocol. It's like the difference between a car's engine and its navigation system.

Haha, I bet the person who wrote this question is a real LoRa-dork. Anyway, I think A is the right answer. LoRa is the cool radio stuff, and LoRaWAN is the boring networking part.

Option A is definitely the answer. LoRa is the low-level radio technology, and LoRaWAN is the networking protocol that runs on top of it. Easy peasy!

Option A seems correct to me. LoRa is the physical layer modulation technique, while LoRaWAN defines the higher network layers and protocols.
