Discuss CWNP CWISA-103 Exam Topic 5 Question 15

What is the primary difference between LoRa and LoRaWAN

ALoRa uses RF and LoRaWAN uses light-based communications

BLoRa is the modulation method (using CSS modulation at the Physical Layer) and LoRaWAN is the MAC sub-layer of the Data Link layer

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

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.

I feel confused about the layers, but B seems right.

Rolande 2 months ago

Agreed! LoRaWAN is the MAC sub-layer. Makes sense.

Delmy 3 months ago

I think the answer is B. LoRa is the modulation method.

Alaine 3 months ago

So, LoRa is just the Physical Layer? Interesting!

Lavonda 3 months ago

C is wrong, LoRaWAN is not the Transport Layer.

Chaya 3 months ago

Wait, I thought LoRa was just for local links?

Keneth 3 months ago

Totally agree with B!

Eladia 3 months ago

B is correct! LoRa is the modulation method.

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.

Ashton 4 months ago

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

Rima 4 months ago

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.

Nelida 4 months ago

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