Q71.
Spectrum decision over heterogeneous spectrum band with different characteristics is a challenge in spectrum management.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:xG users operate in licensed and unlicensed spectrum bands. In licensed spectrum bands, the operations of the primary users are collected during spectrum analysis and the decision taken should not affect the primary user transmission. Likewise, intelligent spectrum sharing algorithms should be selected for xG users operating on the licensed bands which have equal rights for spectrum access.
Q72.
What is spectrum mobility?

a.

Spectrum mobility involves seamless channel switchover

b.

Spectrum mobility involves sharing spectrum information among secondary users

c.

Spectrum mobility involves managing spectrum sensing and spectrum sharing

d.

Spectrum mobility involves sharing spectrum information between secondary users and xG base station

Discuss
Answer: (a).Spectrum mobility involves seamless channel switchover Explanation:Spectrum mobility involves performing seamless channel switchover while maintaining the performance of current secondary user communication. Spectrum mobility is required when degradation of the current channel condition is observed or when the primary user arrives in the licensed band.
Q73.
Which among the following statements is false?

a.

Arrival of primary user triggers handoff

b.

Primary user communication is of high priority

c.

Secondary user can occupy licensed spectrum band until completion of communication

d.

Secondary user moving in a band should not interrupt primary user communication

Discuss
Answer: (c).Secondary user can occupy licensed spectrum band until completion of communication Explanation:In the licensed band, primary user communication holds a higher priority than the secondary user. The primary user can initiate handoff by appearing in the licensed spectrum band. It can also initiate handoff when secondary user transmission coverage overlaps with that of a primary user in the same band.
Q74.
What are the units of spectrum mobility?

a.

Spectrum sensing and spectrum sharing

b.

Spectrum handoff and spectrum management

c.

Connection management and spectrum management

d.

Spectrum handoff and connection management

Discuss
Answer: (d).Spectrum handoff and connection management Explanation:Spectrum handoff is the process of transferring current data communication from one channel to another channel. Connection management adjusts the protocols associated with each layer of the OSI model to sustain the quality of service requirements of secondary user communication.
Q75.
Which among the following is a concern of a primary user?

a.

Link maintenance probability

b.

Number of handoff

c.

Handoff latency

d.

Effective data rate

Discuss
Answer: (c).Handoff latency Explanation:Spectrum handoff is the process of transferring current data communication from one channel to another channel. The delay caused by spectrum handoff is termed as handoff latency. High handoff latency at the secondary user increases the amount of interference at the primary user.
Q76.
Which among the following is an essential feature of spectrum mobility in FTP communication?

a.

Storage of packets

b.

Authentication

c.

Encryption

d.

Data recovery

Discuss
Answer: (a).Storage of packets Explanation:Connection management in spectrum mobility enforces protocols with respect to the application for maintaining communication. FTP requires protocols to store packets that are transmitted during handoff. But real-time applications do not require storage of packets as the information is obsolete for the corresponding application.
Q77.
Which among the following is the basic unit of spectrum pool?

a.

Contiguous licensed spectrum band

b.

Non-contiguous licensed spectrum band

c.

Contiguous unlicensed spectrum band

d.

Contiguous licensed spectrum band

Discuss
Answer: (d).Contiguous licensed spectrum band Explanation:The spectrum pool comprises of a collection of contiguous licensed spectrum bands. Each spectrum band contains several channels. A spectrum band is considered as a preliminary bandwidth unit for operating any wireless access technology.
Q78.
What is link maintenance probability?

a.

Link maintenance probability is the measure of duration of transmission before handoff

b.

Link maintenance probability is the measure of sustenance of transmission during handoff

c.

Link maintenance probability is the measure of duration to find back-up channels

d.

Link maintenance probability is the measure of the strength of link during transmission

Discuss
Answer: (b).Link maintenance probability is the measure of sustenance of transmission during handoff Explanation:Link maintenance probability is the measure of sustenance of the communication of secondary user, when the secondary user vacates a channel. Link maintenance probability increases with the number of handoffs. Link maintenance probability is one of the performance measuring parameters of spectrum mobility.
Q79.
Which among the following is integrated in IEEE 802.22 Wireless Regional Area Network?

a.

Route decision model

b.

Back up channel list

c.

Interference floor

d.

Spectrum decision model

Discuss
Answer: (b).Back up channel list Explanation:The most preferred approach for mitigating performance degradation, due to poor channel characteristics, is building a backup channel list. The potential target channels are added to a list. The list is maintained by sharing information between users in the area. It is integrated in the IEEE 802.22 Wireless Regional Area Network.
Q80.
What is the terminology used for a handoff between spectrum bands without changing the current base station?

a.

Intra-cell/Intra-pool handoff

b.

Inter-cell/Intra-pool handoff

c.

Inter-cell/inter-pool handoff

d.

Intra-cell/inter-pool handoff

Discuss
Answer: (a).Intra-cell/Intra-pool handoff Explanation:When an xG user switches from one spectrum band to another in the same spectrum pool without selecting an alternate base station, it is termed as intra-cell/intra-pool handoff. A cell is a unit of coverage area. Spectrum pool is a set of contiguous licensed spectrum bands.
