Which technology is specifically designed for high-speed wireless communication over large distances?

WiMAX, which stands for Worldwide Interoperability for Microwave Access, is specifically designed for high-speed wireless communication over large distances. While Wi-Fi is typically used for local area networks (LANs) and operates over shorter ranges, WiMAX can cover much larger areas, often up to several miles, making it suitable for metropolitan area networks (MANs). This long-range capability is facilitated by its use of licensed and unlicensed spectrum, allowing for greater bandwidth and higher data transmission rates.

WiMAX is particularly advantageous in scenarios where traditional wired connections would be impractical or too costly, such as rural or underserved regions. It supports various applications, including broadband internet access and connectivity for multiple users simultaneously, providing a solution to bridge the digital divide.

In contrast, VoIP (Voice over Internet Protocol) is a technology primarily focused on enabling voice communication over the internet and does not pertain to wireless communication protocols or distances. Ethernet is a wired networking technology, and while it establishes high-speed local area connections, it lacks the wireless capabilities necessary for the scenario described. Therefore, WiMAX stands out as the appropriate choice for high-speed wireless communication over extended distances.
