Final answer:
The radio frequencies between 300 and 3,000 MHz fall under the ultra high frequency (UHF) band and are used in various technologies such as UHF TV broadcasts, 4G cellular networks, GPS, and Wi-Fi.
Step-by-step explanation:
The ultra high frequency (UHF) band, spanning from 300 to 3,000 MHz, underpins a diverse array of technologies crucial to modern communication. Within this spectrum, television broadcasts (470 to 1000 MHz), 4G cellular signals (around 880 MHz), Global Positioning System (GPS) transmissions (1.228 and 1.575 GHz), and Wi-Fi networks (2.4 to 5 GHz) thrive. These frequencies offer distinct advantages, notably their reduced absorption by common building materials, rendering them ideal for indoor and urban environments. This characteristic enhances the reliability and efficiency of various applications, contributing to seamless connectivity in our daily lives.
From entertainment through television to the precision of GPS and the ubiquity of Wi-Fi, the UHF band plays a pivotal role in shaping the interconnected landscape of modern technology.
