This part of the Cellular Network has 37 MCQs questions along with answers and their explanations.
1. What is the general frequency range for a CDMA network?
- 600 to 1350 MHz
- 700 to 1500 MHZ
- 700 to 2333 MHz
- 700 to 2500 MHz
Answer & Explanation
Answer: (4) 700 to 2500 MHz
Explanation:
A typical CDMA device service frequency ranges from 700 to 2500 MHz.
2. What is the full form of CDMA?
- Code Division Multiple Device Authenticity
- Code Division Machine Access
- Code Division Multi-user Access
- Code Division Multiple Access
Answer & Explanation
Answer: (4) Code Division Multiple Access
Explanation:
CDMA stands for Code Division Multiple Access.
3. In the network and communication, ranges are typically referred to as?
- Ranged Web
- Bands
- Bandwidth
- Broad-width
Answer & Explanation
Answer: (2) Bands
Explanation:
In-network and communication, ranges are referred to Bands such as tri-band and quad-band.
4. Which type of mobile device generally doesn’t have SIM slots?
- CDMA Phone
- GSM Phone
- TDMA Phone
- All devices have SIM slots
Answer & Explanation
Answer: (1) CDMA
Explanation:
CDMA phones don’t pose SIM slots.
It means, NO SIM = CDMA Phone.
While GSM phones have a dedicated SIM slot. But some CDMA phones need SIM cards.
5. Assertion (A): CDMA uses Analog to digital conversion which if transmitted are nearly impossible to clone.
Reason (R): Because transmission frequency varies according to a defined pattern. There are trillions of these patterns which make it hard to clone.
- Both (A) and (R) are correct
- (A) is correct, but (R) is incorrect
- Both (A) and (R) are incorrect
- (A) is incorrect, but (R) is correct
Answer & Explanation
Answer: (1) Both (A) and (R) are correct
Explanation:
No explanation for this Forensic Cellular Network MCQ question.
6. Which of the cellular network is based on TDMA?
- GSM
- CDMA
- Both (1) & (2)
- None of the above
Answer & Explanation
Answer: (1) GSM
Explanation:
GSM is based on the TDMA technique. TDMA stands for Time Division Multiple Access
7. GSM stands for:
- Golden System of Mobile
- Global System of Mobile Device
- Global System of Mobile Communication
- Global System for Mobile Communication
Answer & Explanation
Answer: (4) Global System for Mobile Communication
Explanation:
GSM is a widely used digital mobile network. Global System for Mobile communication uses a variation of time division multiple access (TDMA).
8. Assertion (A): At transmission from GSM device, information is transformed into digital data and is given a specific time slot. Similarly, at the receiver end, it has to be the same specific time slot to get digital data.
Reason (R): It is the basis of all cellular communication.
- Both (A) and (R) are correct
- (A) is correct, but (R) is incorrect
- Both (A) and (R) are incorrect
- (A) is incorrect, but (R) is correct
Answer & Explanation
Answer: (2) (A) is correct, but (R) is incorrect
Explanation:
In the general scenario, the assertion statement (A) only defines the basis of GSM digital wireless telephony services, not all other communication services.
9. CDMA uses which transmission techniques?
- Analog to digital data packets
- Patterns
- Voice data packets
- 12 bits packet data
Answer & Explanation
Answer: (2) Patterns
Explanation:
CDMA uses a defined pattern transmission technique.
10. GSM uses which of the following transmission technique?
- TDMA
- Voice data packets
- 12 bits packets data
- Digital packets Data by Cellular networks
Answer & Explanation
Answer: (1) TDMA
Explanation:
Transmission techniques used in GSM technology is Time Division Multiple Access (TDMA)
11. What is the set frequency range for GSM networks?
- 750 to 2100 MHz
- 750 to 2800 MHz
- 850 to 2100 MHz
- 850 to 2800 MHz
Answer & Explanation
Answer: (3) 850 to 2100 MHz
Explanation:
The frequency range for a GSM network is 850 to 2100 MHz.
Note: It is noted that these ranges may differ as per the network services carrier you choose, but all fall in the range of 850 to 2100 MHz.
12. Assertion (A): All CDMA phone does not possess SIM card slots.
Reason (R): Because all CDMA device does not need a SIM to connect to a cellular network.
- Both (A) and (R) are correct
- (A) is correct, but (R) is incorrect
- Both (A) and (R) are incorrect
- (A) is incorrect, but (R) is correct
Answer & Explanation
Answer: (3) Both (A) and (R) are incorrect
Explanation:
Assertion (R) and reason (R) is wrong because some CDMA devices need SIM cards to connect. Example: 4G CDMA device.
13. Assertion (A): All GSM mobile device needs a SIM to connect to cellular networks.
Reason (R): Without SIM in GSM mobile, any calls are not allowed.
- Both (A) and (R) are correct
- (A) is correct, but (R) is incorrect
- Both (A) and (R) are incorrect
- (A) is incorrect, but (R) is correct
Answer & Explanation
Answer: (3) Both (A) and (R) are incorrect
Explanation:
In case of emergency, a GSM mobile does not need a SIM to communicate. Example calling 911.
