Question No: 55 – (Topic 1)

North America is in which of the following International Telecommunications Union (ITU) regulatory regions?

  1. 2

  2. 3

  3. One

  4. 4

Question No: 56 – (Topic 1)

A technician is assisting with a site analysis of a passive ultra high frequency (UHF) RFID system

for a conveyor application requiring several antennas to be placed in close proximity. The BEST reason for using absorptive materials would be to:

  1. absorb the RF from outside interference sources.

  2. protect the interrogator#39;s receiver from becoming saturated.

  3. decrease the likelihood of electrostatic discharge (ESD) affecting performance.

  4. increase the size of the field pattern covered by the antennas.

Answer: B

Answer: B

Question No: 58 – (Topic 1)

When comparing ultra high frequency (UHF) passive to high frequency (HF) passive RFID, which of the following statements is MOST accurate? (Select TWO).

  1. UHF is able to operate in highly reflective environments and worse at anti-collision.

  2. HF is less susceptible to RF absorbent material and better for long read range applications.

  3. UHF is more susceptible to RF absorbent material and better for high data rate applications.

  4. HF is more susceptible to highly reflective environments and better for close range applications.

Answer: C,D

Question No: 59 – (Topic 1)

Backscattering operates by:

  1. alternating between linear and circular polarization.

  2. using spread-spectrum to equalize the power over the band.

  3. transmitting with power from the interrogator.

  4. changing the reflection coefficient of the antenna.

Answer: D

Question No: 60 – (Topic 1)

An interrogator emits one watt from its antenna connector. The energy passes through a cable with 3dB loss to a linearly-polarized antenna with 6dB gain. Which of the following would be the Effective Isotropic Radiated Power (EIRP)?

  1. 4 watts

  2. 2 watts

  3. 0.5 watt

  4. one watt
