The range of a Wi-Fi signal from a router depends on several factors, including the frequency band (2.4 GHz or 5 GHz), the environment (walls, floors, and other obstructions), and the power of the router. Here’s a general overview:
2.4 GHz Wi-Fi Signal Range
- Indoors: The 2.4 GHz band typically has a better range than 5 GHz because it can penetrate walls and other obstacles more effectively. Indoors, the range is usually around 150 feet (46 meters).
- Outdoors: Without obstacles, the 2.4 GHz signal can reach up to 300 feet (91 meters) or more in ideal conditions.
5 GHz Wi-Fi Signal Range
- Indoors: The 5 GHz band offers faster speeds, but has a shorter range and is more susceptible to interference from walls and other obstacles. Indoors, the range is usually around 50 to 100 feet (15 to 30 meters).
- Outdoors: In an open area without obstructions, the 5 GHz signal might reach up to 200 feet (61 meters), but this can vary greatly depending on the environment.
Factors Affecting Wi-Fi Range:
- Obstacles: Walls, floors, and furniture can significantly reduce the range, especially for 5 GHz signals.
- Router Power: Higher-end routers with more powerful antennas may provide better range.
- Interference: Other electronic devices, such as microwaves or cordless phones, can interfere with Wi-Fi signals, particularly on the 2.4 GHz band.
- Environment: Open spaces allow for longer range, while cluttered or heavily partitioned environments reduce it.
In summary, while 2.4 GHz Wi-Fi can reach farther, the 5 GHz band offers higher speeds but with a shorter effective range.
