Internet of Things (IoT) Practice Exam 2025 – Comprehensive Prep Resource

Mobile 4G/LTE technology is designed to provide high bandwidth and significant range, making it fundamentally different from the other options listed. In terms of bandwidth, 4G/LTE networks offer data rates that can reach up to several hundred megabits per second, depending on the specific implementation and conditions. This high data capacity allows for robust mobile internet experiences, enabling activities like video streaming, online gaming, and extensive web browsing.

Additionally, the range of 4G/LTE technology is considerably broader than the technologies mentioned in the other choices. While it may vary from one location to another, 4G networks can typically cover several kilometers of distance from a cell tower in urban and suburban areas, making them suitable for wide-area communications.

In contrast, the other technologies listed, such as NFC, Bluetooth, and LoRa, are characterized by their lower bandwidth and range, limiting their applications to more localized communications. For instance, NFC operates effectively over very short distances (a few centimeters) with low bandwidth, and Bluetooth has slightly increased range and bandwidth but is still considered low by the standards of mobile broadband. LoRa, meanwhile, is designed for long-range, low-power communication; however, its bandwidth is also limited. Therefore, the
