What is the maximum communication range of Wi-Fi?

The communication range of Wi-Fi depends on several factors, including the signal strength of the router, the device's receiving capability, and environmental obstacles such as walls or interference from other electronic devices. Generally, a standard home Wi-Fi router can cover an indoor range of approximately 30 to 50 meters (about 100 to 165 feet). In open outdoor environments, the communication range might be longer, but the actual distance can vary depending on the specific performance of the Wi-Fi module being used. It’s important to test the range in the actual environment to determine the most accurate distance for your setup.

What Wi-Fi protocols are supported?

Wi-Fi technology is typically based on the IEEE 802.11 series of standards, with the following key versions:

1. 1. 802.11b: One of the earliest Wi-Fi standards, offering a maximum transfer rate of 11 Mbps and operating on the 2.4 GHz frequency band. It’s often used in older devices.
   2. 802.11g: This standard increases the maximum data rate to 54 Mbps while still using the 2.4 GHz frequency band. It’s commonly found in older Wi-Fi routers and devices.
   3. 802.11n: A significant improvement over earlier versions, 802.11n offers faster speeds and better coverage. It supports multiple antennas (MIMO) and operates on both the 2.4 GHz and 5 GHz bands.
   4. 802.11ac (Wi-Fi 5): A more recent standard that provides faster transfer speeds, reduced interference, and operates primarily on the 5 GHz frequency band. It is commonly used in modern Wi-Fi routers and devices.
   5. 802.11ax (Wi-Fi 6): The latest Wi-Fi standard, Wi-Fi 6 offers even faster transfer speeds, lower latency, and better network capacity management. It also improves performance in environments with many connected devices, providing a more stable and efficient connection.
