Q11.
The primary user must contain legacy protocols and xG protocols for xG communication.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Primary users do not undergo any modification to support xG base-stations and xG users. The operation of the primary user should not be hindered by unlicensed users. Similarly the xG users operating on the licensed band should not affect other primary users.
Q12.
What is the function of the xG network in the licensed band?

a.

Exploit unused spectrum holes

b.

Route xG users

c.

Route primary users

d.

Manage information for primary users

Discuss
Answer: (a).Exploit unused spectrum holes Explanation:The xG users on the xG network exploit the unused spectrum holes that are available for a limited time in the licensed spectrum band. This may be carried out by applying various cognitive communication techniques.
Q13.
Which among the following is an additional function carried out xG users in the licensed band?

a.

Route primary users

b.

Detection of the presence of primary users

c.

Detection of the presence of secondary users

d.

Route secondary users

Discuss
Answer: (b).Detection of the presence of primary users Explanation:An xG user should ensure that the primary user is not affected by the operations of the xG users. The primary user does not have the capability to detect the presence of the primary user and request for termination of the connection. Hence the xG user listens for the arrival of the primary user.
Q14.
Which among the following affects the channel capacity of spectrum holes?

a.

Interference at nearby primary users

b.

Interference at nearby xG users

c.

Distance between the xG user and primary base-station

d.

Distance between the xG user and xG base-station

Discuss
Answer: (a).Interference at nearby primary users Explanation:The amount of primary users prone to interference caused by xG users in unused spectrum holes of licensed spectrum band determines the channel capacity of spectrum holes. Interference avoidance with primary users is an important criterion in the design of xG architecture.
Q15.
What is the terminology used to refer to the transfer of users from one spectrum to another spectrum?

a.

Spectrum routing

b.

Mobile routing

c.

Mobile handoff

d.

Spectrum handoff

Discuss
Answer: (d).Spectrum handoff Explanation:If a primary user returns to a spectrum band currently being used by an xG user, the xG user should remove itself from the spectrum and continue operating in a different spectrum band immediately. This is referred to as spectrum handoff.
Q16.
Which among the following relies on efficient allocation of spectrum?

a.

Effective multiplexing

b.

Effective modulation

c.

Capacity of open spectrum access

d.

Diversity

Discuss
Answer: (c).Capacity of open spectrum access Explanation:Factors such as the capacity of open spectrum access and quality of service rely on the ability of a radio to efficiently allocate radio spectrum. xG network architecture aims for effective use of unlicensed spectrum band which have multiple heterogeneous networks.
Q17.
Which among the following is true about xG users in an unlicensed spectrum band?

a.

xG user has equal rights to access the spectrum

b.

xG user vacate the spectrum band upon arrival of the primary user

c.

xG user vacate the spectrum band upon arrival of another xG user

d.

xG users compete for the position of primary user

Discuss
Answer: (a).xG user has equal rights to access the spectrum Explanation:In the unlicensed spectrum band, each user has the same right to access the spectrum bands. The xG users present in one particular area may use the same portion of the spectrum band for communication.
Q18.
Which among the following is required for effective use of spectrum in an unlicensed spectrum band?

a.

Spectrum sharing algorithms

b.

Scheduling algorithms

c.

Planning algorithms

d.

Decision-making algorithms

Discuss
Answer: (a).Spectrum sharing algorithms Explanation:xG users compete to access the unlicensed spectrum band since every user has an equal right to access the spectrum. Intelligent spectrum sharing algorithms ensure effective spectrum usage and good quality of service. If many xG networks are present, impartial sharing on a network level is required.
Q19.
Which among the following may not be achieved by using xG networks for military applications?

a.

Select intermediate frequency bandwidth

b.

Improve security

c.

Select compatible modulation scheme

d.

Reduce interference

Discuss
Answer: (d).Reduce interference Explanation:xG networks allow the selection of intermediate frequency bandwidth, and compatible modulation and coding techniques. It is capable of adapting to the changing radio environment of a battlefield. xG networks also carry out secure spectrum handoff.
Q20.
Which among the following is a requirement of emergency networks?

a.

Quality of service

b.

Determine of charges for usage

c.

Minimum latency

d.

Parsing incoming information

Discuss
Answer: (c).Minimum latency Explanation:Emergency networks require minimum latency, and a large radio spectrum to accommodate a high volume of traffic including voice, video, and data. Since xG networks do not rely entirely on fixed infrastructure for communication and are capable of utilizing unused spectrum bands, they are used for reliable communication under emergency conditions.
