CWNP Exam CWISA-102 Topic 3 Question 27 Discussion

Actual exam question for CWNP's CWISA-102 exam
Question #: 27
Topic #: 3
[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.

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!

User 2: Oh, I see. So LoRa is more about how the data is transmitted, while LoRaWAN is about the network structure.
