1. What is the maximum communication range of WiFi?
The communication range of WiFi depends on various factors including router signal strength, device reception capability, and environmental interferences. Typically, standard home WiFi routers have an indoor coverage range of approximately 30 meters to 50 meters. In open outdoor environments, the communication distance may be greater, but specific distances require testing based on the WiFi module's performance.
2. What protocols does WiFi support?
WiFi technology standards are typically based on the IEEE 802.11 series protocols, which include the following main standards:
- 802.11b: The earliest WiFi standard with a maximum transmission rate of 11 Mbps, operating in the 2.4 GHz frequency band.
- 802.11g: Provides a maximum transmission rate of up to 54 Mbps, operating in the 2.4 GHz frequency band.
- 802.11n: Offers higher transmission rates and improved coverage, supports multiple-input multiple-output (MIMO) technology, and operates in both the 2.4 GHz and 5 GHz frequency bands.
- 802.11ac: Commonly referred to as WiFi 5, it offers higher transmission rates and reduced interference. It primarily operates
- 802.11ax: Known as WiFi 6, it is the latest WiFi standard that offers higher transmission rates, lower latency, and improved network capacity management.
