With reference to communication technologies, what is/are the difference/differences between LTE (Long-Term Evolution) and VoLTE (Voice over Long-Term Evolution)?
1. LTE is commonly marketed as 3G and VoLTE is commonly marketed as advanced 3G.
2. LTE is data-only technology and VoLTE is voice-only technology.
Select the correct answer using the code given below.
A
1 only
B
2 only
C
Both 1 and 2
D
Neither 1 nor 2
Correct Answer: Option D
Explanation
1. Statement 1 is incorrect. LTE (Long-Term Evolution) is a 4G wireless broadband standard, not commonly marketed as 3G. VoLTE (Voice over Long-Term Evolution) is a feature of LTE that allows voice calls over the 4G data network; it is not marketed as 'advanced 3G'.
2. Statement 2 is incorrect. While LTE was initially developed with a focus on high-speed data, it is the underlying network. VoLTE is specifically the technology that uses the LTE network to carry voice calls as data packets. VoLTE is not a 'voice-only technology' separate from the LTE data network; it is voice *over* the LTE data network. Without VoLTE, LTE networks often used older technologies (like 3G) for voice calls.
3. Therefore, neither statement accurately describes the difference.
