how far can wifi reach

The distance that Wi-Fi can reach depends on several factors, including:

1. Frequency band: Wi-Fi signals can operate on two main frequency bands: 2.4 GHz and 5 GHz. The 2.4 GHz band has a longer range, but it’s more prone to interference. The 5 GHz band has a shorter range, but it’s less prone to interference.
2. Router power: The power of the router’s transmitter affects the range of the Wi-Fi signal. More powerful routers can cover larger areas.
3. Antenna type: The type of antenna used on the router and devices can impact the range. External antennas can improve the range, while internal antennas may have a shorter range.
4. Physical barriers: Walls, floors, and ceilings can block or weaken Wi-Fi signals. Thicker materials like concrete or metal can reduce the range more than thinner materials like wood or drywall.
5. Interference: Other devices that use the same frequency band, such as cordless phones, microwaves, and neighboring Wi-Fi networks, can interfere with your Wi-Fi signal and reduce its range.

Typical Wi-Fi range estimates:

• Indoor range:

  • 2.4 GHz band: 150-200 feet (45-60 meters)
  • 5 GHz band: 100-150 feet (30-45 meters)

• Outdoor range:

  • 2.4 GHz band: 300-500 feet (90-150 meters)
  • 5 GHz band: 200-300 feet (60-90 meters)

To give you a better idea, here are some approximate Wi-Fi range estimates for different environments:

• Small apartment: 100-200 feet (30-60 meters)
• Medium-sized house: 200-400 feet (60-120 meters)
• Large house: 400-600 feet (120-180 meters)
• Office building: 500-1,000 feet (150-300 meters)
• Outdoor public area: 1,000-2,000 feet (300-600 meters)

Keep in mind that these estimates are rough and can vary depending on the specific environment and the factors mentioned above.
