The correct answer is D. LTE based network.
3G (third-generation) cellular networks are a set of standards for mobile telecommunications that provide an array of services, including voice, data, and multimedia. 3G networks are designed to offer higher speeds and data rates than previous generations of cellular networks, such as 2G and 2.5G.
Some of the key features of 3G networks include:
- Voice over IP (VoIP): 3G networks support VoIP, which allows users to make and receive phone calls using data instead of traditional voice channels.
- Unparalleled network capacity: 3G networks are designed to handle much more traffic than previous generations of cellular networks. This allows for more users to be connected to the network at the same time, and for data to be transferred at higher speeds.
- Multi-megabit Internet access: 3G networks support data rates of up to 2 Mbps, which is much faster than the data rates supported by 2G and 2.5G networks. This allows users to access the Internet and download data much faster.
- Multimedia support: 3G networks support multimedia services, such as video calling, streaming music, and downloading games and applications.
LTE (Long Term Evolution) is a standard for 4G cellular networks. LTE networks are designed to offer even higher speeds and data rates than 3G networks. LTE networks are already being deployed in many parts of the world, and they are expected to become the dominant type of cellular network in the future.
Therefore, the answer to the question “Which of the following is not a characteristic of 3G network?” is D. LTE based network.
