Final answer:
LTE (Long-Term Evolution) is the technology that is similar to WiMAX, offering wireless broadband service with a maximum data rate of 84 Mbps. It provides higher capacity and speed compared to 3G and is different from Wi-Fi, which is a short-range wireless technology.
Step-by-step explanation:
The technology similar to WiMAX that offers wireless broadband service and has a maximum data rate of 84 Mbps is LTE (Long-Term Evolution). LTE is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is an improvement over the older 3G technology and provides increased capacity and speed using a different radio interface and core network improvements. On the other hand, Wi-Fi is more localized wireless technology that typically provides internet access within a short range of a wireless router which uses microwaves in the frequencies of 2.4 GHz to 5 GHz.
