Which of the following defines a first generation cellular technology?

The choice that defines first-generation cellular technology accurately describes the characteristics of these early mobile communication systems. First-generation (1G) networks were primarily analog systems that utilized frequencies around 30 KHz. They were designed to provide basic voice communication and had very low data transmission speeds, commonly around 2 Kbps.

This speed and frequency reflect the limitations and the specifications of 1G systems, which were meant for voice calls rather than data services. As technology evolved, subsequent generations (2G, 3G, and beyond) introduced digital communication and significantly higher data speeds, moving away from the analog foundation of first-generation technologies.

The other choices refer to either higher frequency ranges or data speeds associated with newer generations of cellular technology, thus making them invalid as representations of first-generation systems. Understanding these distinctions helps in recognizing the advancements in mobile technology and the gradual improvements in communication capabilities.
