CWISA-103 Question #33: Real Exam Question with Answer & Explanation

The correct answer is B. LoRa is the modulation method (using CSS modulation at the Physical Layer) and LoRaWAN is. 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

Question

What is the primary difference between LoRa and LoRaWAN

Options

ALoRa uses RF and LoRaWAN uses light-based communications
BLoRa is the modulation method (using CSS modulation at the Physical Layer) and LoRaWAN is
CLoRa is the Physical Layer and LoRaWAN is the Transport Layer
DLoRa is used for communicating across the Internet and LoRaWAN is used only on the local link

Explanation

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.
