Which frequency band is commonly associated with 4G and 5G cellular services?

The frequency band commonly associated with 4G and 5G cellular services indeed falls under the category of high GHz frequencies. These technologies utilize a range of frequency bands that extend into the higher frequency spectrum, allowing for increased data capacity and faster speeds.

For instance, 4G LTE predominantly uses frequencies starting from 700 MHz up to 2.6 GHz; however, 5G significantly expands its range, utilizing frequencies from sub-1 GHz all the way up to 100 GHz and even higher in some cases. The utilization of high GHz frequencies is pivotal in unlocking the potential for low latency and enhanced bandwidth, which are fundamental characteristics of 5G technology.

In contrast, the other options represent frequencies typically used for different applications. The 2.4 GHz and 5 GHz bands are primarily associated with Wi-Fi communications. The sub-GHz band, while relevant for various other communication protocols and IoT usage, does not encompass the primary frequency ranges utilized by 4G and 5G networks. Therefore, selecting high GHz frequencies accurately reflects the advanced capabilities and uses of modern cellular technologies.
