CWNP Exam CWISA-102 Topic 1 Question 17 Discussion

Actual exam question for CWNP's CWISA-102 exam
Question #: 17
Topic #: 1
[All CWISA-102 Questions]

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.

Haha, I love the confusion between LoRa and LoRaWAN. It's like trying to tell apart your Wi-Fi router and your internet service provider. But hey, at least this question is testing our networking knowledge, not our comedy chops.

Hmm, I think option B is the winner here. LoRa is the modulation technique, while LoRaWAN is the higher-level protocol that builds on top of it. Simple as that!

User 2: That makes sense. LoRaWAN is like the next level up from LoRa.

I agree, option B is correct. LoRa is the modulation method and LoRaWAN is the MAC sub-layer.

Correct me if I'm wrong, but isn't LoRaWAN kind of like the Wi-Fi of the LoRa world? It's the standard that governs how devices communicate on the LoRa network. I'm pretty sure that's the primary distinction.

I believe LoRa is used for long-range communication, while LoRaWAN is more about managing the network and data.

I agree with Helene, LoRaWAN is more about the network layer while LoRa is about the physical layer.

Ah, I remember learning about this in my networking class. The key difference is that LoRa is the physical layer technology, while LoRaWAN is the protocol that defines the MAC layer and network architecture. Pretty straightforward if you ask me.
