Which technology is marketed as a high-speed alternative to DSL and early 2G and 3G cellular internet?

WiMAX stands for Worldwide Interoperability for Microwave Access, and it is a wireless communication technology designed to provide high-speed internet access over a wide area. It was developed to serve as a faster alternative to traditional DSL connections, as well as early-generation cellular networks like 2G and 3G. WiMAX offers broader coverage and can deliver data at higher rates, making it suitable for both fixed and mobile broadband applications.

The technology uses microwave frequencies to transmit data and can support multiple users and devices simultaneously. Its ability to deliver high-speed internet wirelessly sets it apart from DSL, which relies on copper telephone lines and has limitations in terms of speed and distance.

While fiber optics also offers high speeds, it isn't specifically marketed as a direct alternative to DSL or early cellular technologies, as it primarily pertains to wired connections. Satellite technology can provide internet access in remote areas, but it typically experiences higher latency and is not classified as a high-speed option compared to WiMAX.
