Which wireless technology offers the greatest coverage area?

Satellite technology offers the greatest coverage area among the listed options because it relies on satellites in space to transmit and receive signals over vast distances. This enables satellite connections to reach remote and rural areas where traditional wired or wireless infrastructures may not be available. Satellite can cover thousands of miles, making it suitable for global communications.

In contrast, Wi-Fi operates over limited distances, typically providing coverage only within a building or a small outdoor area. Bluetooth is designed for short-range communication, typically around 30 feet or 10 meters, and is used for connecting devices like headphones or keyboards to other devices. Wired Ethernet, while offering a stable connection, is constrained by the length of cables and is generally used in localized networks like homes or office buildings. Thus, satellite technology distinctly stands out for its extensive coverage capability.
