With reference to communications 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.
✓ Correct answer: d) Neither 1 nor 2
ExplanationStatement 1 is incorrect: LTE is a 4G (Fourth Generation) wireless communication standard, not 3G.It offers higher data transfer speeds compared to 3G technologies.VoLTE is a service that allows voice calls to be transmitted over the LTE network thereby providing high-quality voice services.Both LTE and VoLTE are associated with 4G technology, not 3G.Statement 2 is incorrect: LTE is not a data-only technology as it supports both data and voice services.However without VoLTE, voice calls on LTE networks typically fall back to 3G or 2G networks (a process called Circuit-Switched Fallback, or CSFB).VoLTE is not voice-only as it enhances voice call quality and efficiency while still supporting data services.73
