CWNP Exam CWISA-102 Topic 5 Question 25 Discussion

Actual exam question for CWNP's CWISA-102 exam
Question #: 25
Topic #: 5
[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.

References:

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.

D) LoRa is used for the internet and LoRaWAN is only for local links? Ah, the old 'internetworks vs. local area networks' trick. Nice try, but I'm not falling for that one.

C) LoRa is the Physical Layer and LoRaWAN is the Transport Layer? Hmm, that doesn't sound quite right. I'm going to have to think about this one a bit more.

A) LoRa uses RF and LoRaWAN uses light-based communications? What is this, some kind of optical version of LoRa? I'm pretty sure that's not right.

B) Oh, I see. So LoRa is more about the modulation technique, while LoRaWAN is about the network protocol.

I think the key difference is that LoRaWAN is the protocol stack for managing communication, while LoRa is just the physical layer technology.

I believe LoRaWAN is designed for long-range communication and LoRa is just the modulation technique.

B) LoRa is the modulation method and LoRaWAN is the MAC sub-layer? That makes sense, I guess I'd better brush up on my networking protocols.
