Q. Consider the following statements:
1.LTE (Long Term Evolution) uses an All-IP architecture that integrates voice, video, and data services on a single Internet Protocol network.
2.VoLTE (Voice over LTE) requires the device to switch back to 2G or 3G networks to complete a voice call, which is why call setup time is increased.
3.VoLTE allows for the simultaneous use of high-speed data and voice calls without interruptions.
Which of the statements given above are correct?
Answer: C
Notes:
Explanation:
Statement 1 is correct: LTE is designed as a packet-switched IP network for better efficiency.
- Statement 2 is incorrect: One of the main benefits of VoLTE is that it does not need to fall back to older 2G/3G networks; it carries voice as data packets over LTE, reducing setup time to ~2 seconds.
- Statement 3 is correct: Unlike older standards, VoLTE supports high-definition voice and data usage at the same time.
