What is the wifi transmission distance range?

The Wi-Fi transmission distance range is between 30 meters and 100 meters in an indoor environment. Its range depends on many factors, including the power of the wireless router, antenna design, environmental conditions and obstacles, etc. Detailed introduction: 1. Wireless router power. The output power of the wireless router is one of the important factors affecting the Wi-Fi transmission distance. Normally, the power range of the wireless router is between 50mW and 200mW. Increasing the power of the wireless router can improve transmission distance, but within the legal range, the power of wireless routers is limited by regulations and regulations, etc.

The range of Wi-Fi transmission distance depends on many factors, including the power of the wireless router, antenna design, environmental conditions and obstacles, etc. Below we will introduce some common factors and technologies and their impact on Wi-Fi transmission distance.

1. Wireless router power: The output power of the wireless router is one of the important factors that affects the Wi-Fi transmission distance. Typically, the power range of wireless routers is between 50mW and 200mW. Increasing the power of a wireless router can improve transmission distance, but within legal limits, the power of wireless routers is limited by laws and regulations.

2. Antenna design: The antenna design of a wireless router has an important impact on the transmission distance and signal strength. The gain of the antenna determines the directivity and transmission range of the wireless signal. High-gain antennas can increase transmission distance, but usually at the expense of signal coverage. Antenna placement and orientation also have an impact on transmission distance.

3. Environmental conditions: Environmental conditions have an important impact on Wi-Fi transmission distance. Open, empty areas generally have longer transmission distances, while confined spaces, walls, obstacles, and other sources of electromagnetic interference reduce transmission distances. Wireless signals are affected by reflection, attenuation and multipath effects during transmission.

4. Frequency band and bandwidth: Wi-Fi networks usually work in two frequency bands: 2.4 GHz and 5 GHz. Under the same power and antenna conditions, the 5 GHz band generally has a shorter transmission distance but can provide higher transmission speeds and less interference. Wider bandwidths (such as 40 MHz or 80 MHz) can provide higher transmission speeds, but usually reduce the transmission distance.

5. Wi-Fi standards: Different Wi-Fi standards have different transmission distances. Newer Wi-Fi standards like 802.11ac and 802.11ax generally have better range and higher transmission speeds. Older standards such as 802.11b and 802.11g generally have shorter transmission ranges.

It should be noted that the specific value of Wi-Fi transmission distance is difficult to determine because it is affected by multiple factors and may vary greatly between different environments and devices. Typically, the Wi-Fi transmission distance in an indoor environment ranges from 30 meters to 100 meters. Outdoors or in open areas, Wi-Fi transmission distances may be farther, up to hundreds of meters.

In order to expand Wi-Fi coverage, you can take the following measures:

- Place the wireless router in a central location to avoid obstacles blocking signal transmission.

- Use high gain antennas or directional antennas to enhance signal transmission.

- Use a Wi-Fi signal extender or repeater to increase coverage.

- Avoid interference with other wireless devices and sources of electromagnetic interference (such as microwave ovens and Bluetooth devices).

To sum up, the range of Wi-Fi transmission distance is affected by many factors, including wireless router power, antenna design, environmental conditions and obstacles, etc. Typically, the Wi-Fi transmission distance in an indoor environment ranges from 30 meters to 100 meters. To extend Wi-Fi coverage, there are steps you can take to enhance signal transmission and reduce interference.
