Which internet of things (loT) connectivity technology operates on the 2.4GHz and 5GHz bands, as well as all bands between 1 and 6GHz when they…

The IEEE 802.11ax standard, marketed as Wi-Fi 6, is the correct technology. It is designed to operate in the 2.4GHz and 5GHz frequency bands, with its extension, Wi-Fi 6E, specifically utilizing the 6GHz band. The standard was developed to significantly increase the average throughput per user in dense environments and has a theoretical maximum data rate of 9.6 Gbit/s, which is in the range of the 11 Gbit/s specified in the question. Its design anticipates the use of additional bands between 1GHz and 7.125GHz as they become available for 802.11 use, making it the only option that fits all the technical requirements for frequency, speed, and future-readiness for high-performance IoT applications.

A. 3G: This is an older cellular technology operating on licensed mobile carrier frequencies, not 2.4/5GHz Wi-Fi bands, with maximum speeds measured in Mbps, not Gbit/s.

B. Z-wave: This is a low-power, low-bandwidth mesh networking protocol for home automation (IoT) that operates in the sub-1GHz band with data rates in the kbps range.

D. C-band: This refers to a broad range of microwave frequencies (typically 4-8 GHz), not a specific communication protocol or standard like 802.11ax.
