CWNP CWISA-103 Exam - Topic 5 Question 15 Discussion

What is the primary difference between LoRa and LoRaWAN
B) LoRa is the modulation method (using CSS modulation at the Physical Layer) and LoRaWAN is the MAC sub-layer of the Data Link layer
A) LoRa uses RF and LoRaWAN uses light-based communications
C) LoRa is the Physical Layer and LoRaWAN is the Transport Layer
D) LoRa is used for communicating across the Internet and LoRaWAN is used only on the local link

What is the primary difference between LoRa and LoRaWAN

Show Suggested Answer Hide 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.


LoRa Modulation:Technical explanations of Chirp Spread Spectrum (CSS).

LoRaWAN Specification:Official documentation detailing the network architecture and MAC layer functions.

OSI Model:Descriptions of the Data Link layer and its role in networking.

So, LoRa is just the Physical Layer? Interesting!

C is wrong, LoRaWAN is not the Transport Layer.

Wait, I thought LoRa was just for local links?

I’m not sure about the exact layers, but I remember LoRaWAN is definitely more about managing the network, while LoRa handles the signal itself.

I’m pretty confident that LoRa is the modulation method, and LoRaWAN is more about the network protocol, so I think B sounds right.

I feel like there was a practice question that mentioned LoRa being the Physical Layer and LoRaWAN being something else, but I can't recall the specifics.

I think I remember that LoRa is related to the modulation technique, but I'm not completely sure about the layers.
