You are considering the implementation of a lab for testing wireless equipment. What is the primary benefit of such a lab? (Choose the single best answer.)
Provides a way to repurpose old hardware that is not ready for final removal
Provides a failover environment for your production systems
Provides for testing to determine how much RF exposure you can tolerate
Provides a safe environment in which to develop practical skills and knowledge of a technology and to test the technology
What function does the IEEE perform in relation to wireless technologies?
Designs wireless chipsets
Represents industry vendors
Promotes technology and standards development
Brings wireless products to market
What part(s) of the OSI network model does the IETF primarily focus on for the development of standards?
Network Layer and above
Physical Layer
All layers
Data Link Layer
What is the role of the ITU in wireless communications?
Defines international communications standards
Oversees communications regulatory agencies in each country
Coordinates the shared global use of the radio spectrum
Establishes wireless radiation exposure limits
What organization maintains and publishes the 802.15.4 Standard?
Bluetooth SIG
IETF
Zigbee Alliance
IEEE
What is the typical range of a wireless body area network (WBAN)?
10 meters
1-2 meters
10 centimeters
10 square meters
Which one of the following is NOT a typical Smart City application?
City-wide municipal Wi-Fi
Pollution monitoring
Demand-based road tolling
Self-driving ride sharing
You have been asked to consider smart building opportunities for your organization. Which one of these is a benefit of smart building technology?
Faster Wi-Fi connectivity
Increased vacation time for building managers
Reduced design and construction costs
Improved operational efficiency
What best describes the area covered or connected by a WWAN?

What is the benefit of using SINR as opposed to SNR to reference signal quality at a receiver?
SNR excludes the noise floor, which skews the results
SNR includes interference measurements that skew the results
SINR includes interference as well as the noise floor
SINR excludes interference and only measures the noise floor
What is defined as the weakening of signal amplitude as the signal passes through a medium?
Attenuation
Diffraction
Reflection
Scattering
How is ASK modulation different from FSK modulation?
FSK is more sensitive to noise than ASK
ASK does not work at high frequencies
ASK can carry more data than FSK
ASK varies the amplitude of the signal while FSK shifts its frequency
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.)
The number of spatial streams, which is the 1/4 the number in the QAM level
The speed of data transfer, which is four times the number in the QAM level
The number of target points in the QAM constellation, which are equivalent to amplitude and phase combinations
The channel width, which is stipulated in MHz
What factor severely limits the range of systems operating in the 60GHz band?
Atmospheric Scattering
Solar Radiation
Rain Fade
Oxygen Fade Answer: D Question: 269
What consideration is found in PtMP systems that is not found in PtP systems?
Interference avoidance
SINR optimization
Airtime management
Frequency selection
