Q3:

What is the typical range of a wireless body area network (WBAN)?

A: 1-2 meters

B: 10 square meters

C: 10 centimeters

D: 10 meters

Correct Answer: A
WBAN Range:Wireless Body Area Networks (WBANs) specialize in short-range communication around the human body. Typical ranges fall within 1-2 meters.

Purpose:This range is designed to:

Connect sensors monitoring health metrics.

Transmit data to a central coordinator device (e.g., smartphone).

Minimize interference potential with other wireless networks.

Q4:

How does OFDMA differ from OFDM?

A: Subcarriers of OFDMA can contain data destined for a different receiver

B: OFDMA offers greater range by using multiple channels at once

C: OFDMA allows multiple devices to transmit simultaneously on the same frequency

D: OFDMA uses multiple radios to achieve higher throughput

Correct Answer: C
OFDM vs. OFDMA:

OFDM (Orthogonal Frequency-Division Multiplexing):Divides a channel into multiple subcarriers for data transmission.

OFDMA (Orthogonal Frequency-Division Multiple Access):Extends OFDM by allowing multiple users to share subcarriers simultaneously, improving efficiency and spectral utilization.
