Not a characteristic of 3G network: LTE based network

Explanation:

3G (Third Generation) network technology revolutionized the way we use mobile devices by providing faster data transmission rates and improved connectivity. It introduced several features and capabilities that were not available in the previous generation networks. Let's discuss each option to determine why LTE based network is not a characteristic of 3G network.

- Communication over VoIP: One of the characteristics of 3G network is the ability to facilitate communication over Voice over Internet Protocol (VoIP). This means that users can make calls using internet connectivity rather than traditional telephone lines. This feature allows for more efficient use of network resources and enables additional services like video calling and multimedia messaging.

- Unparalleled network capacity: 3G network offers a significant improvement in network capacity compared to its predecessors. It has the ability to handle a large number of simultaneous connections, allowing more users to access the network without experiencing significant bottlenecks. This increased capacity enables better network performance and supports a wide range of data-intensive applications.

- Multi-megabit Internet access: Another key characteristic of 3G network is the provision of multi-megabit Internet access. This means that users can enjoy faster download and upload speeds, allowing them to stream videos, browse the web, and download files at a much higher rate compared to previous generations.

- LTE based network: LTE (Long Term Evolution) is a technology that was introduced in the 4G network. It is not a characteristic of 3G network. LTE offers even faster data transmission rates, improved network capacity, and lower latency compared to 3G. It provides a seamless experience for data-intensive applications, such as online gaming, video streaming, and video conferencing.

In conclusion, while communication over VoIP, unparalleled network capacity, and multi-megabit Internet access are all characteristics of 3G network, LTE based network is not. LTE is a technology that belongs to the 4G network and offers additional features and capabilities beyond what 3G can provide.
