What does the number in the various Quadrature Amplitude Modulation levels, such as 16 in QAM-16 and 64 in QAM-64, indicate? (Choose the single best answer.)
- A . The speed of data transfer, which is four times the number in the QAM level
- B . The channel width, which is stipulated in MHz
- C . The number of target points in the QAM constellation, which are equivalent to amplitude and phase combinations

What primary component is required to implement a wireless transceiver in a device?
- A . GPIO pins
- B . SRAM
- C . Flash memory
- D . Radio
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
What metric is used to express a relative increase or decrease in signal strength?
- A . W
- B . dBm
- C . dB
- D . mW
As an RF signal propagates it becomes weaker at any given measurement point as it gets farther away from the transmitter.
What concept is described?
- A . RF latency
- B . Free Space Path Loss
- C . Beamwidth
- D . Diffraction
