[All CWISA-102 Questions]

How does OFDMA differ from OFDM?

ASubcarriers of OFDMA can contain data destined for a different receiver

BOFDMA offers greater range by using multiple channels at once

COFDMA allows multiple devices to transmit simultaneously on the same frequency

DOFDMA uses multiple radios to achieve higher throughput

Show Suggested Answer

Suggested Answer: D

Legacy Support:The primary reason to continue using older wireless technologies is the need to connect with devices that don't support newer standards (e.g., old sensors or equipment).

Other Reasons (Not as Strong):

Cost:Replacing legacy devices can be expensive.

Reliability:Some legacy technologies might be well-proven in specific settings.

Option D seems a bit too futuristic. I mean, who needs multiple radios when you can just use a single one and still get the job done, am I right?

Hmm, I'm not sure. OFDMA seems pretty complicated. I just hope I don't have to explain it to my grandparents, they still think the internet is a series of tubes!
