Which cellular technology operates at frequencies of 2-8GHz and provides speeds between 100 Mbps to 1 Gbps?

The technology that operates within the frequency range of 2-8 GHz and can provide high-speed data transmissions between 100 Mbps and 1 Gbps is 4G. Specifically, 4G networks were designed to support advanced services such as high-definition mobile TV, video conferencing, and other data-heavy applications that require faster and more reliable connections.

4G technology utilizes various frequency bands to deliver improved performance over previous generations, and the specified frequency range is critical for enabling higher data rates and increased capacity. Although LTE (Long-Term Evolution), often associated with 4G, can technically fit into this category, it is important to recognize that not all LTE implementations reach the upper speed limits defined for 4G in general terms.

Therefore, when specifically referencing the broader capabilities of 4G technology, it is accurate to identify it as the correct answer in this context.
