Q171.
Which among the following factors hinders effective spectrum usage according to the SPTF?

a.

Lack of spectrum access

b.

Lack of antenna technology

c.

Lack of physical components of radios

d.

Lack of high capacity processors

Discuss
Answer: (a).Lack of spectrum access Explanation:Spectrum Policy Task Force identified the lack of capacity is due to the current regulations applied on spectrum access. SPTF supported multiple dimensional access of the spectrum. The FCC relies on SPTF to create spectrum policies and spectrum management techniques that could lead to better overall usage of the available spectrum.
Q172.
Which among the following areas will not have an impact on cognitive radio?

a.

Maximize the flexibility of spectrum usage

b.

Promote spectrum access in rural areas

c.

Apply a qualitative approach to interference management

d.

Allow easement for spectrum overlays and underlays

Discuss
Answer: (c).Apply a qualitative approach to interference management Explanation:The recommendations proposed by SPTF maximize spectrum usage by allowing unlicensed users and promotes opportunistic spectrum access through secondary market policies. The SPTF promotes spectrum access in rural areas by altering the power levels, leasing, and geographical licensing.
Q173.
The calculation of relative values of consumer services compared with scientific investigation and Earth exploration is a challenge imposed on policymakers by the mobile transmitter, mobile receiver configuration.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:The calculation of relative values of consumer services compared with scientific investigation and Earth exploration is a challenge imposed on policymakers by the mobile transmitter, fixed receiver configuration. This information helps in assigning the usefulness of creating a mechanism to access an unused spectrum in a location.
Q174.
Which among the following is false about the defence science board?

a.

Defence Science Board comprises of technology and business experts

b.

Defence Science Board is a Federal Advisory Committee for the US Department of Defence

c.

Defence Science Board researches for the FCC

d.

Defence Science Board is identified that using spectrum multiple dimension can reduce spectrum scarcity

Discuss
Answer: (c).Defence Science Board researches for the FCC Explanation:Defence Science Board is an advisory committee composed of technology and business experts, which conducts research pertaining to the US department of defence. It identified that by utilizing the spectrum in multiple dimensions such as time, frequency, and modulation, spectrum scarcity can be reduced. It promoted real-time sharing of spectrum.
Q175.
Which among the following do not belong to the fixed transmitter, mobile receiver configuration?

a.

Broadcasting

b.

Radio position determination

c.

Radio astronomy

d.

Standard time signal services

Discuss
Answer: (c).Radio astronomy Explanation:Broadcasting primarily includes consumer communication applications such as AM, FM, etc. Radio positioning includes services such as GPS and radio navigation. The long-wave standard time signal produced by The National Institute of Standards and Technology (NIST) which continuously broadcasts time and frequency signals at 60 kHz is an example of standard time signal services.
Q176.
Which among the following is a policy challenge for the fixed transmitter, mobile receiver configuration?

a.

Determining transmission parameters to avoid interference

b.

Determining reception parameters to avoid interference

c.

Determining the distance of propagation to avoid interference

d.

Determining coverage area to avoid interference

Discuss
Answer: (a).Determining transmission parameters to avoid interference Explanation:The major policy challenge for the fixed transmitter, mobile receiver configuration is the determination of transmission parameter levels which do not cause interference and are economically feasible. For example, determining the number of stations required for broadcasting in a region.
Q177.
Which among the following would result in increased out-of-band rejection at receivers while broadcasting?

a.

Periodic transmissions

b.

Increased transmission power

c.

Frequency reuse

d.

Close band spacing between stations

Discuss
Answer: (d).Close band spacing between stations Explanation:The close band spacing between stations is a potential method for increasing the station density. However it causes increased out-of-band rejection at the receivers. Reduction of transmission and increased frequency reuse are other approaches for increasing station density. However these methods result in reduced coverage.
Q178.
Which among the following is true about passive sensing configuration?

a.

Transmitter location is unknown

b.

Receiver location is unknown

c.

Base station location is unknown

d.

Operational area is unknown

Discuss
Answer: (d).Operational area is unknown Explanation:Mobile transmitter, fixed receiver configuration includes active and passive meteorological and Earth exploration system. In passive sensing configuration, the operational area is unknown. In the active sensing configuration, the transmitter location is unknown.
Q179.
What device characteristic is necessary for the mobile transmitter, fixed receiver configuration?

a.

Sensitive transmitter

b.

Sensitive receiver

c.

Sensitive analog to digital converter

d.

Sensitive digital to analog converter

Discuss
Answer: (b).Sensitive receiver Explanation:Mobile transmitter, fixed receiver configuration employs sensitive receivers. Sensitive receivers require the adjacent channel systems to have small out-of-band emission. This is achieved by using guard bands.
Q180.
Which among the following configurations include radio astronomy services?

a.

Fixed transmitter, mobile receiver

b.

Mobile transmitter, mobile receiver

c.

Fixed transmitter, fixed receiver

d.

Mobile transmitter, fixed receiver

Discuss
Answer: (c).Fixed transmitter, fixed receiver Explanation:Fixed transmitter, fixed receiver configuration includes point-to-point, point-to-multipoint, and radio astronomy services. Both endpoints are in fixed locations. The communication path may be one way between the transmitter and receiver or it may be two way between two transceivers.
