The maximum effective distance for WiFi transmission is indeed around 300 feet. This distance can vary depending on several factors such as the specific standards being used for WiFi (such as 802.11n or 802.11ac), environmental obstacles, and interference from other electronic devices.
WiFi operates in the 2.4 GHz and 5 GHz frequency bands. The 2.4 GHz band tends to have a longer range due to its ability to penetrate walls and obstacles better than the 5 GHz band, but it is also more susceptible to interference. Under optimal conditions and using the appropriate technology, distances can approach 300 feet or more.
In practical terms, while this may represent a maximum theoretical distance, the effective and reliable distance for connectivity might be less in real-world settings. Thus, when planning for WiFi coverage, it’s important to consider these factors, which can affect the actual performance of the network at greater distances.
