Q11.
Which among the following connection is established by xG base-station?

a.

Single hop for xG users

b.

Multi-hop for xG users

c.

Single hop for primary users

d.

Multi-hop for primary users

Discuss
Answer: (a).Single hop for xG users Explanation:xG base-station is capable of providing single hop connection for xG users accessing the licensed portion of the spectrum. It is similar to a primary base-station with fixed network infrastructure network components however it has additional xG capabilities.
Q12.
Which among the following statements is false about spectrum broker?

a.

Spectrum broker is also known as scheduling server

b.

Spectrum broker is connected to multiple networks

c.

Spectrum broker bridges primary network and xG network

d.

Spectrum broker is a central network entity

Discuss
Answer: (c).Spectrum broker bridges primary network and xG network Explanation:Spectrum broker is responsible for sharing the spectrum resources among the different users of the xG network. It also works as an information manager supporting the combined operation of several xG networks. A spectrum broker is connected to each network in an area for coordinated operation.
Q13.
What does the term spectrum heterogeneity mean in the context of xG architecture?

a.

Licensed band and unlicensed band

b.

UHF band and VHF band

c.

Radio band and visible light band

d.

Radio band and infrared band

Discuss
Answer: (a).Licensed band and unlicensed band Explanation:xG architecture exists in a mixed spectrum environment with licensed and unlicensed bands. Wideband access technology allows xG users to operate on both bands. xG users can communicate by using a base-station or by opting for a multi-hop connection.
Q14.
Which among the following does not come under network heterogeneity?

a.

xG network access

b.

xG ad hoc access

c.

Primary network access

d.

xG spectrum access

Discuss
Answer: (d).xG spectrum access Explanation:xG network access refers to the communication established via xG base-station on licensed and unlicensed spectrum band. xG ad hoc access refers to communication among xG users using an ad hoc connection on licensed and unlicensed spectrum band. Primary network access refers to the communication carried out using primary base-station on licensed spectrum band.
Q15.
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.
Q16.
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.
Q17.
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.
Q18.
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.
Q19.
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.
Q20.
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.
