In which frequency band do mobile phones generally function?

1. 1–100 MHz
2. 100–200 MHz
3. 1000–2000 MHz
4. 800–950 MHz

Correct answer: 800–950 MHz

Solution

Mobile phones typically operate within the 800–950 MHz frequency band, which is part of the UHF spectrum used for cellular communication, allowing for effective transmission and reception of signals over varying distances.
