Final answer:
The claim that 3G cell phone systems are based on LTE technology is false. 3G predates LTE, which is considered a 4G technology. 3G provides lower-speed data services in comparison to LTE.
Step-by-step explanation:
The statement that third-generation (3G) cell phone systems are based on LTE technology is false. 3G technologies are based on a set of telecommunications standards that preceded LTE, which stands for Long-Term Evolution. LTE is a standard for wireless broadband communication and is considered to be a 4G technology, not 3G. 3G systems provide mobile telecommunications services and support mobile data along with voice and video calls but at lower speeds compared to LTE.
The evolution of mobile networks has been marked by a transition from the earlier 2G networks mainly for voice and simple data, to 3G which improved on data speeds, and then to 4G/LTE which offers high-speed internet and improved data services. A cell phone uses a radio receiver and a weak radio transmitter that operates on microwave frequencies, enabling it to communicate with a network through various broadcast towers as the user moves from one location to another.
