Final answer:
LTE is a data communications technology often marketed as 4G, and VoLTE allows voice calls over LTE, enhancing call quality and affordability. The correct answer is [D] Neither 1 nor 2.
Step-by-step explanation:
The differences between LTE (Long-Term Evolution) and VoLTE (Voice over Long-Term Evolution) are commonly misunderstood. First, LTE is not commonly marketed as 3G but as 4G, which is a standard for wireless communication of high-speed data for mobile phones and data terminals.
It is a data-only technology, enabling internet access for mobile devices and data terminals. On the other hand, VoLTE is a standard for high-speed wireless communication for mobile phones and data terminals but it is specifically for voice communication. It allows users to make voice calls over LTE, enabling better-quality phone service and the potential for cheaper phone calls, especially long distance.
This shift toward improved communication methods like VoLTE is an extension of the trend where improvements in technology, such as microwave transmission and communications satellites, allowed multiple firms to provide telephone services, breaking up monopolies and leading to more consumer choice.
Therefore, the correct answer to the question is [D] Neither 1 nor 2 because LTE is a data communications technology marketed as 4G and VoLTE is a technology for voice calls that also uses the LTE network, not a separate voice-only technology.
