Practice questions
Q1With reference to licensed and licence-exempt spectrum, consider the following statements: 1. Wi-Fi uses licence-exempt bands subject to prescribed limits. 2. Commercial mobile 5G generally uses licensed spectrum assigned under telecom law. Which of the statements given above is/are correct?
Both statements are correct. Wi-Fi operates in licence-exempt bands within technical limits, whereas commercial mobile 5G generally relies on licensed spectrum assigned under telecom law. The two categories therefore do not follow identical assignment rules.
Q2Match List I with List II and select the correct answer using the code given below: List I (5G concept) A. Enhanced mobile broadband B. Massive machine-type communication C. Ultra-reliable low-latency communication D. Backhaul List II (Principal role) 1. Connects cell sites to the core network 2. Supports a very large number of connected sensors 3. Targets industrial control and safety uses requiring reliability and low delay 4. Provides high data rates for video and fixed wireless access
Enhanced mobile broadband provides high data rates for video and fixed wireless access; massive machine-type communication connects many sensors; ultra-reliable low-latency communication targets reliability-sensitive industrial and safety uses; and backhaul links cell sites to the core network. Therefore, option A gives the correct matching.
Q3Arrange the following components in the order in which user data ordinarily travels from a 5G handset towards an external service platform: A. Backhaul or transport network B. External data network or service platform C. Radio access network D. Core network Select the correct answer using the code given below.
The handset first connects over the air to the radio access network. Traffic then crosses the backhaul or transport link to the core network, which handles routing and connection to the external data network or service platform. Thus option C gives the correct order.
Q4With reference to spectrum bands used for 5G, consider the following statements: 1. Low-band spectrum generally provides wider coverage and better indoor reach than high-band spectrum. 2. Mid-band spectrum offers a practical balance between coverage and capacity. 3. A higher carrier frequency by itself guarantees a higher user data speed. 4. Millimetre-wave bands can provide very wide channels but generally have shorter range. Select the correct answer using the code given below.
Statements 1, 2 and 4 are correct. Low bands favour coverage and penetration, mid bands balance coverage and capacity, and millimetre-wave bands offer wide channels over shorter distances. Statement 3 is incorrect because usable bandwidth, antennas, backhaul and congestion also affect speed.
Q5With reference to telecom law and institutions in India, consider the following statements: 1. Union List Entry 31 provides Parliament with the principal legislative field for telecom, wireless and broadcasting. 2. TRAI itself assigns spectrum after fixing reserve prices and band plans. 3. Section 4 of the Telecommunications Act, 2023 makes auction the general route for spectrum assignment, subject to First Schedule exceptions. 4. The 2012 Presidential Reference held that auction is constitutionally mandatory for every natural resource in every situation. Select the correct answer using the code given below.
Statements 1 and 3 are correct. TRAI recommends spectrum terms, while the Department of Telecommunications and the Central Government handle assignment under law. The 2012 Presidential Reference clarified that auction is not mandatory for every natural resource in every situation.

6With reference to 5G network architecture, consider the following statements: 1. Massive multiple-input multiple-output creates additional spectrum for a network operator. 2. Edge computing is automatically present at every 5G tower. 3. A non-standalone 5G deployment uses a 5G core network without relying on a 4G core anchor. 4. A standalone 5G deployment can better support network slicing and low-latency uses. Select the correct answer using the code given below.
