You are constructing a wireless network for a business custo

You are constructing a wireless network for a business customer and are developing a rough Wi-Fi access point placement plan. The access points all comply with the 802.11n standard and use the 5 GHz operating frequency. Assuming there are no obstacles in the area where you are constructing the wireless network, what is the maximum indoor range for radio signals for 802.11n devices?

A. 25 meters

B. 35 meters

C. 50 meters

D. 75 meters

Solution

C. The maximum range for radio waves transmitted by 802.11n-compliant devices is approximately 50 meters in an indoor environment. This assumes that there are no obstructions or any sort of interference. During an actual site survey to be conducted before constructing a Wi-Fi network, you would establish any barriers such as concrete pillars or metal cabinets that could limit range or circumstances that could result in radio “dead spots.” The outdoor range for 802.11n is approximately 250 meters.
