Of the following options, what is not the highlight of the eLTE-loT solution is ()?

eLTE-IoT is a Low Power Wide Area (LPWA) technology designed for applications requiring low power consumption, deep coverage, and massive connections, not high bandwidth. Its key features include long battery life (up to 10 years), support for a large number of devices per cell, and reliable connections using unlicensed ISM spectrum. High broadband speeds, such as 100 Mbps uplink, are characteristic of standard 4G/5G technologies and are contrary to the design principles of eLTE-IoT, which prioritizes efficiency and power saving over data throughput.

A. eLTE-IoT is specifically designed to operate on the unlicensed ISM spectrum, making this a key highlight for flexible deployment.
B. Low power consumption is a fundamental advantage of eLTE-IoT, enabling long-term battery operation for terminals.
C. Supporting massive connections is a core design goal of eLTE-IoT to cater to the high density of devices in typical IoT scenarios.
