Name two common wireless frequencies and discuss their typical use cases.

• A. 2.4 GHz: longer range but more interference; 5 GHz: higher speed but shorter range.
• B. 2.4 GHz: shorter range and less interference; 5 GHz: lower speed and more interference.
• C. 900 MHz: common for Wi-Fi; 2.4 GHz and 5 GHz
• D. 3 GHz and 4 GHz

Answer: (A)

Lower wireless frequencies travel farther and penetrate obstacles more effectively, while higher frequencies carry more data but lose strength more quickly with distance and through walls. Two common Wi‑Fi bands reflect this: 2.4 GHz typically provides longer range and broader coverage, but it’s crowded with many devices (Bluetooth, microwaves, cordless phones, etc.), so interference is more likely. On the other hand, 5 GHz supports higher data speeds and has more channels, with generally less interference, but its signal doesn’t travel as far and is more easily attenuated by walls and distance. This combination is why many networks are dual-band, letting devices choose between the broader reach of 2.4 GHz and the faster performance of 5 GHz as needed. Other frequency options listed aren’t standard Wi‑Fi bands and don’t describe the typical trade-offs accurately.
