Q1.
Which among the following statements is true about the wireless network without xG architecture?

a.

Existing wireless networks exhibit homogeneity in the spectrum policies and heterogeneity in the communication technologies

b.

Existing wireless networks exhibit heterogeneity in the spectrum policies and homogeneity in the communication technologies

c.

Existing wireless networks exhibit homogeneity in the spectrum policies and the communication technologies

d.

Existing wireless networks exhibit heterogeneity in the spectrum policies and the communication technologies

Discuss
Answer: (d).Existing wireless networks exhibit heterogeneity in the spectrum policies and the communication technologies Explanation:The currently available wireless networks express heterogeneity in both spectrum policies and communication technologies. For the effective incorporation of communication protocols, a clearly defined xG architecture model is required.
Q2.
Which among the following statement is true about the primary network?

a.

Primary network handles requests from xG users

b.

Primary network uses the spectrum band periodically

c.

Primary network has a dedicated spectrum band

d.

Primary network competes for access to a spectrum band

Discuss
Answer: (c).Primary network has a dedicated spectrum band Explanation:The currently available fixed infrastructure wireless network represents a primary network. It possesses the rights of a dedicated spectrum band. Cellular networks and TV broadcast networks are examples of the primary network.
Q3.
Which among the following options should replace the labels ‘A’, ‘B’, and ‘C’?

a.

Status monitor, Policy engine, Policy database

b.

Policy database, Policy engine, Status monitor

c.

Status monitor, Policy database, Policy engine

d.

Policy engine, Policy database, Status monitor

Discuss
Answer: (b).Policy database, Policy engine, Status monitor Explanation:The policy engine interprets and enforces spectrum policies. Additionally, it overlooks platform events to provoke alteration in the radio function. The interface between the policy engine and radio platform represents the controlling and monitoring functions of the radio.
Q4.
What are terms that should replace the label ‘A’ and ‘B’?

a.

Predefined protocols, Rule based protocols

b.

Static algorithms, Situation aware protocols

c.

Situation aware protocols, Static algorithms

d.

Rule based protocols, Predefined protocols

Discuss
Answer: (b).Static algorithms, Situation aware protocols Explanation:Under good network conditions, good throughput with low latency can be achieved with minimal protocol support. However with deteriorating channel conditions, advanced protocol mechanisms capable of adapting to the changing channel conditions required. These protocols have compensatory mechanisms extending towards applications that are not satisfied by traditional architectures.
Q5.
Which among the following options should replace the labels ‘A’ and ‘B’ in the model implementation of radio environment map?

a.

Learning, Local/Global radio environment map, Awareness, Decision

b.

Learning, Awareness, Local/Global radio environment map, Decision

c.

Awareness, Learning, Decision, Local/Global radio environment map

d.

Awareness, Local/Global radio environment map, learning, decision

Discuss
Answer: (c).Awareness, Learning, Decision, Local/Global radio environment map Explanation:The Radio Environment Map (REM) obtains information from sensor input of radio and the knowledge provided by network support. Awareness is obtained through observed information and REM. Learning helps the radio to adapt with the help of past experiences, decisions, observations, and plans. After a decision is taken, the REM is updated.
Q6.
Which among the following options should replace the label ‘A’, ‘B’, and ‘C’ in rule based system?

a.

Memory, Inference Engine, Knowledge Base

b.

Memory, Knowledge Base, Inference Engine

c.

Knowledge Base, Memory, Inference Engine

d.

Inference Engine, Memory, Knowledge Base

Discuss
Answer: (c).Knowledge Base, Memory, Inference Engine Explanation:The knowledge base of the rule based system is composed of rules specified in the form of “if-then” clauses. The memory unit consists of the current state of the system. The inference engine is responsible for pattern matching.
Q7.
Which among the following statement is false about the primary user?

a.

Primary users are also known as licensed users

b.

Primary users have exclusive right to use a spectrum band

c.

Primary users are a part of the primary network

d.

Primary users compete with the secondary users to access the spectrum band

Discuss
Answer: (d).Primary users compete with the secondary users to access the spectrum band Explanation:Primary users have exclusive rights to use a spectrum band. The primary base-station is responsible for monitoring and controlling the users accessing the spectrum band. Primary users have higher priority when compared to secondary users.
Q8.
What are the units of the primary network?

a.

Primary node and primary base-station

b.

Primary user and primary base-station

c.

Primary user and secondary user

d.

Primary user and primary node

Discuss
Answer: (b).Primary user and primary base-station Explanation:Primary users are licensed users of the spectrum. Primary base-station refers to the fixed infrastructure network component with a spectrum license. The primary base-station contains legacy protocols and xG protocols for supporting communication through xG networks.
Q9.
Which among the following is not a term used to refer to the xG network?

a.

Cognitive radio network

b.

Intelligent spectrum access network

c.

Dynamic spectrum access network

d.

Unlicensed network

Discuss
Answer: (b).Intelligent spectrum access network Explanation:The xG network is also known as the secondary network, unlicensed network, cognitive radio network and dynamic spectrum access network. The xG does not have an exclusive right to use any spectrum band. xG networks aim to make use of temporarily unused spectrum bands.
Q10.
What are the types of structures used to develop xG networks?

a.

Infrastructure and ad hoc networks

b.

Only infrastructure network

c.

Only ad hoc networks

d.

Centralised and distributed infrastructure network

Discuss
Answer: (a).Infrastructure and ad hoc networks Explanation:xG networks are made up of both infrastructure networks as well as ad hoc networks. xG users exist in a mixed spectrum environment and possess additional features to transmit on the licensed band. The path between the sender and the receiver depends on the type of network.
